Definitions

  • the present invention relates to a process for producing particles of amine reaction product.
  • perfumed products are well-known in the art. However, consumer acceptance of such perfumed products like laundry and cleaning products is determined not only by the performance achieved with these products but also by the aesthetics associated therewith. The perfume components are therefore an important aspect of the successful formulation of such commercial products.
  • perfume additives make such compositions more aesthetically pleasing to the consumer, and in some cases the perfume imparts a pleasant fragrance to fabrics treated therewith.
  • the amount of perfume carried-over from an aqueous laundry bath onto fabrics is often marginal and does not last long on the fabric.
  • fragrance materials are often very costly and their inefficient use in laundry and cleaning compositions and ineffective delivery to fabrics results in a very high cost to both consumers and laundry and cleaning manufacturers. Industry, therefore, continues to seek with urgency for more efficient and effective fragrance delivery in laundry and cleaning products, especially for improvement in the provision of long-lasting fragrance to the fabrics.
  • the mixing of the amine reaction product with a carrier having specific melting point to form a particle fulfills such a need.
  • the obtained particle is thereafter treated to form a coated particle.
  • both viscous and non-viscous amine reaction product when processed by the present invention exhibit better deposition and long lasting release than amine reaction product which have not been processed according to this process.
  • the mixing with such carrier acts as a shell around the amine reaction product, thus protecting it from the aggressive wash liquor as well as enhancing its fabric deposition properties.
  • viscous it is meant a product which has a viscosity higher than 1000 cps.
  • the viscosity is measured on a rheometer, TA Instrument CSL 2 100 at a temperature of 25C with a gap setting of 500 microns.
  • the carrier for use herein has a melting point, measured at atmospheric pressure, of less than 30°C.
  • the present invention is a process for making particles of amine reaction product of a compound containing a primary and/or secondary amine functional group and an active ketone or aldehyde containing component, and which comprises the steps of:
  • the processed amine reaction product is further processed to form a coated particle.
  • the processed amine reaction product or coated particle is incorporated in a finished composition.
  • the amine reaction product for use herein is a product of reaction between a compound containing a primary and/or secondary amine functional group and an active ketone or aldehyde containing component, so called hereinafter "amine reaction product".
  • primary and/or secondary amine it is meant a component which carries at least one primary and/or secondary amine and/or amide function.
  • the primary and/or secondary amine compound is also characterized by an Odour Intensity Index of less than that of a 1% solution of methyl anthranilate in dipropylene glycol.
  • Odour Intensity Index it meant that the pure chemicals were diluted at 1% in Dipropylene Glycol, odor-free solvent used in perfumery. This percentage is more representative of usage levels.
  • Smelling strips, or so called “blotters” were dipped and presented to the expert panellist for evaluation. Expert panellists are assessors trained for at least six months in odor grading and whose gradings are checked for accuracy and reproducibility versus a reference on an on-going basis. For each amine compound, the panellist was presented two blotters: one reference (Me Anthranilate, unknown from the panellist) and the sample. The panellist was asked to rank both smelling strips on the 0-5 odor intensity scale, 0 being no odor detected, 5 being very strong odor present.
  • a general structure for the primary amine compound of the invention is as follows: B-(NH2) n ; wherein B is a carrier material, and n is an index of value of at least 1.

  • Perfumed products are well-known in the art. However, consumer acceptance of such perfumed products like laundry and cleaning products is determined not only by the performance achieved with these products but also by the aesthetics associated therewith. The perfume components are therefore an important aspect of the successful formulation of such commercial products.
  • It is also desired by consumers for treated fabrics to maintain the pleasing fragrance over time. Indeed, perfume additives make such compositions more aesthetically pleasing to the consumer, and in some cases the perfume imparts a pleasant fragrance to fabrics treated therewith. However, the amount of perfume carried-over from an aqueous laundry bath onto fabrics is often marginal and does not last long on the fabric. Furthermore, fragrance materials are often very costly and their inefficient use in laundry and cleaning compositions and ineffective delivery to fabrics results in a very high cost to both consumers and laundry and cleaning manufacturers. Industry, therefore, continues to seek with urgency for more efficient and effective fragrance delivery in laundry and cleaning products, especially for improvement in the provision of long-lasting fragrance to the fabrics.
  • It has recently been found that an amine reaction product of a compound containing a primary amine functional group and an active ketone or aldehyde containing component fulfills such a need. Disclosure of such compounds can be found in recently filed applications EP 98870227.0, EP 98870226.2, EP 99870026.4, and EP 99870025.6, all incorporated herein by reference.
  • However, a problem now encountered with the use of these compound is their ease of incorporation into fully formulated compositions. Indeed, such amine reaction products are often viscous which renders their incorporation into these fully formulated compositions more cumbersome.
  • It is therefore an object of the invention to provide amine reaction product in a form suitable for easy incorporation into fully formulated composition.
  • It has now been found that the mixing of the amine reaction product with a carrier having specific melting point to form a particle fulfills such a need. Depending on the property of the carrier, the obtained particle is thereafter treated to form a coated particle.
  • Further, it has also been advantageously found that both viscous and non-viscous amine reaction product when processed by the present invention exhibit better deposition and long lasting release than amine reaction product which have not been processed according to this process. Not to be bound by theory, it is believed that the mixing with such carrier acts as a shell around the amine reaction product, thus protecting it from the aggressive wash liquor as well as enhancing its fabric deposition properties.
  • By "viscous", it is meant a product which has a viscosity higher than 1000 cps. The viscosity is measured on a rheometer, TA Instrument CSL2 100 at a temperature of 25C with a gap setting of 500 microns.
  • The carrier for use herein has a melting point, measured at atmospheric pressure, of less than 30°C.
    • Summary of the invention
  • The present invention is a process for making particles of amine reaction product of a compound containing a primary and/or secondary amine functional group and an active ketone or aldehyde containing component, and which comprises the steps of:
  • a)-providing the amine reaction product, and
  • b)-mixing therewith a carrier having a melting point of less than 30°C.
  • In a preferred embodiment of the invention, the processed amine reaction product is further processed to form a coated particle.
  • In another aspect of the invention, the processed amine reaction product or coated particle is incorporated in a finished composition.
    • Detailed description of the invention Starting materials 1)-Amine reaction product
  • The amine reaction product for use herein is a product of reaction between a compound containing a primary and/or secondary amine functional group and an active ketone or aldehyde containing component, so called hereinafter "amine reaction product".
  • A typical disclosure of amine reaction product suitable for use herein can be found in recently filed applications EP 98870227.0, EP 98870226.2, EP 99870026.4, and EP 99870025.6, all incorporated herein by reference.
    • A-Primary and/or secondary amine
  • By "primary and/or secondary amine", it is meant a component which carries at least one primary and/or secondary amine and/or amide function.
  • Preferably, the primary and/or secondary amine compound is also characterized by an Odour Intensity Index of less than that of a 1% solution of methyl anthranilate in dipropylene glycol.
    • Odour Intensity Index method
  • By Odour Intensity Index, it meant that the pure chemicals were diluted at 1% in Dipropylene Glycol, odor-free solvent used in perfumery. This percentage is more representative of usage levels. Smelling strips, or so called "blotters", were dipped and presented to the expert panellist for evaluation. Expert panellists are assessors trained for at least six months in odor grading and whose gradings are checked for accuracy and reproducibility versus a reference on an on-going basis. For each amine compound, the panellist was presented two blotters: one reference (Me Anthranilate, unknown from the panellist) and the sample. The panellist was asked to rank both smelling strips on the 0-5 odor intensity scale, 0 being no odor detected, 5 being very strong odor present.
    • Results:
  • The following represents Odour Intensity Index of an amine compound suitable for use in the present invention and according to the above procedure. In each case, numbers are arithmetic averages among 5 expert panellists and the results are statistically significantly different at 95% confidence level:
    Methylanthranilate 1% (reference) 3.4
    Ethyl-4-aminobenzoate (EAB) 1% 0.9
  • A general structure for the primary amine compound of the invention is as follows: B-(NH2)n;
    wherein B is a carrier material, and n is an index of value of at least 1.
  • Compounds containing a secondary amine group have a structure similar to the above excepted that the compound comprises one or more -NH- groups instead of -NH2. Further, the compound structure may also have one or more of both -NH2 and -NH- groups.
  • Preferred B carriers are inorganic or organic carriers.
  • By "inorganic carrier", it is meant carrier which are non-or substantially non carbon based backbones.
  • Preferred primary and/or secondary amines, among the inorganic carriers, are those selected from mono or polymers or organic-organosilicon copolymers of amino derivatised organo silane, siloxane, silazane, alumane, aluminum siloxane, or aluminum silicate compounds.

Preferred polyamines are polyethyleneimines commercially available under the tradename Lupasol like Lupasol FG (MW 800), G20wfv (MW 1300), PR8515 (MW 2000), WF (MW 25000), FC (MW 800), G20 (MW 1300), G35 (MW 1200), G100 (MW 2000), HF (MW 25000), P (MW 750000), PS (MW 750000), SK (MW 2000000), SNA (MW 1000000).
  • Preferred amino acids for use herein are selected tyrosine, tryptophane, lysine, glutamic acid, glutamine, aspartic acid, arginine, asparagine, phenylalanine, proline, glycine, serine, histidine, threonine, methionine, and mixture thereof, most preferably selected from tyrosine, tryptophane, and mixture thereof.

They can contain alanine, serine, aspartic acid, arginine, valine, threonine, glutamic acid, leucine, cysteine, histidine, lysine, isoleucine, tyrosine, asparagine, methionine, proline, tryptophan, phenylalanine, glutamine, glycine or mixtures thereof. In chemically modified amino acids, the amine or acidic function of the amino acid has reacted with a chemical reagent. This is often done to protect these chemical amine and acid functions of the amino acid in a subsequent reaction or to give special properties to the amino acids, like improved solubility. Examples of such chemical modifications are benzyloxycarbonyl, aminobutyric acid, butyl ester, pyroglutamic acid. More examples of common modifications of amino acids and small amino acid fragments can be found in the Bachem, 1996, Peptides and Biochemicals Catalog.
  • Preferred polyamino acids are polylysines, polyarginine, polyglutamine, polyasparagine, polyhistidine, polytryptophane or mixtures thereof. Most preferred are polylysines or polyamino acids where more than 50% of the amino acids are lysine, since the primary amine function in the side chain of the lysine is the most reactive amine of all amino acids.
  • The preferred polyamino acid has a molecular weight of 500 to 10.000.000, more preferably between 5.000 and 750.000.
  • The polyamino acid can be cross linked. The cross linking can be obtained for example by condensation of the amine group in the side chain of the amino acid like lysine with the carboxyl function on the amino acid or with protein cross linkers like PEG derivatives. The cross linked polyamino acids still need to have free primary and/or secondary amino groups left for reaction with the active ingredient.
  • The preferred cross linked polyamino acid has a molecular weight of 20.000 to 10.000.000, more preferably between 200.000 and 2.000.000.
  • The polyamino acid or the amino acid can be co-polymerized with other reagents like for instance with acids, amides, acyl chlorides. More specifically with aminocaproic acid, adipic acid, ethylhexanoic acid, caprolactam or mixture thereof. The molar ratio used in these copolymers ranges from 1:1 (reagent/ amino acid (lysine)) to 1:20, more preferably from 1:1 to 1:10.
  • The polyamino acid like polylysine can be partially ethoxylated.
  • Examples and supply of polyaminoacids containing lysine, arginine, glutamime, asparagine are given in the Bachem 1996, Peptides and Biochemicals catalog.
  • The polyaminoacid can be obtained before reaction with the active ingredient, under a salt form. For example polylysine can be supplied as polylysine hydrobromide. Polylysine hydrobromide is commercially available from Sigma, Applichem, Bachem and Fluka.
  • Examples of suitable amino functional polymers containing at least one primary and/or secondary amine group for the purpose of the present invention are :

    • N,N'-bis-(3-aminopropyl)-1,3-propanediamine linear or branched (TPTA); and
    • 1,4-bis-(3-aminopropyl) piperazine (BNPP).
  • The more preferred compounds are selected from ethyl-4-amino benzoate, polyethyleneimine polymers commercially available under the tradename Lupasol like Lupasol FG, G20,wfv, PR8515, WF, FC, G20, G35, G100, HF, P, PS, SK, SNA; the diaminobutane dendrimers Astramol®, polylysine, cross-linked polylysine, N,N'-bis-(3-aminopropyl)-1,3-propanediamine linear or branched; 1,4-bis-(3-aminopropyl) piperazine, and mixtures thereof. Even most preferred compounds are those selected from ethyl-4-amino benzoate, polyethyleneimine polymers commercially available under the tradename Lupasol like Lupasol FG, G20,wfv, PR8515, WF, FC, G20, G35, G100, HF, P, PS, SK, SNA; polylysine, cross-linked polylysine, N,N'-bis-(3-aminopropyl)-1,3-propanediamine linear or branched, 1,4-bis-(3-aminopropyl) piperazine, and mixtures thereof.
  • Advantageously, such most preferred primary and/or secondary amine compounds also provide fabric appearance benefit, in particular colour appearance benefit, thus providing a resulting amine reaction product with the dual properties of both fabric appearance benefit and delayed release of the active. Further, when the primary and/or secondary amine compound has more than one free primary and/or secondary amine group, several different active ingredients (aldehyde and/or ketone) can be linked to the amine compound.

  • In the above list of perfume ingredients, some are commercial names conventionally known to one skilled in the art, and also includes isomers. Such isomers are also suitable for use in the present invention.
  • In another embodiment, especially suitable for the purpose of the present invention are the perfume compounds, preferably the perfume ketones or aldehydes, characterised by having a low Odor Detection Threshold. Such Odor Detection Threshold (ODT) should be lower than 1ppm, preferably lower than 10ppb - measured at controlled Gas Chromatography (GC) conditions such as described here below. This parameter refers to the value commonly used in the perfumery arts and which is the lowest concentration at which significant detection takes place that some odorous material is present, as referred to for example in "Compilation of Odor and Taste Threshold Value Data (ASTM DS 48 A)", edited by F. A. Fazzalari, International Business Machines, Hopwell Junction, NY and in Calkin et al., Perfumery, Practice and Principles, John Willey & Sons, Inc., page 243 et seq (1994). For the purpose of the present invention, the Odor Detection Threshold is measured according to the following method :
    The gas chromatograph is characterized to determine the exact volume of material injected by the syringe, the precise split ratio, and the hydrocarbon response using a hydrocarbon standard of known concentration and chain-length distribution. The air flow rate is accurately measured and, assuming the duration of a human inhalation to last 0.02 minutes, the sampled volume is calculated. Since the precise concentration at the detector at any point in time is known, the mass per volume inhaled is known and hence the concentration of material. To determine the ODT of a perfume material, solutions are delivered to the sniff port at the back-calculated concentration. A panelist sniffs the GC effluent and identifies the retention time when odor is noticed. The average over all panelists determines the threshold of noticeability. The necessary amount of analyte is injected onto the column to achieve a certain concentration, such as 10 ppb, at the detector. Typical gas chromatograph parameters for determining odor detection thresholds are listed below.

    • 2)-Carrier
  • Another essential ingredient of the process invention is a carrier having a melting point of less than 30°C, preferably between minus 150°C and less than 30°C. By means of this carrier, particles of amine reaction product, suitable for spray-on application, will be produced.
  • Typical of such carrier includes liquid as well as solid carrier material. The liquid carrier can be in any suitable physical form like hydrophobic or hydrophilic form.
  • As used herein in relation to carrier materials, "hydrophobic" means substantially water insoluble; "hydrophilic" means substantially water soluble. In this regard, "substantially water insoluble" shall refer to a material that is not soluble in distilled (or equivalent) water, at 25.degree. C., at a concentration of 0.2% by weight, and preferably not soluble at 0.1% by weight (calculated on a water plus carrier weight basis). "Substantially water soluble" shall refer to a material that is soluble in distilled (or equivalent) water, at 25.degree. C., at a concentration of 0.2% by weight, and are preferably soluble at 1.0% by weight. The terms "soluble", "solubility" and the like, for purposes hereof, corresponds to the maximum concentration of carrier, as applicable, that can dissolve in water or other solvents to form a homogeneous solution, as is well understood to those skilled in the art.
  • Typical of materials that are in hydrophobic form include ingredients useful in perfumery. Typical of such ingredients are the perfume raw materials, solvents, and mixtures thereof. Typical hydrophobic raw materials include the ketones or aldehydes like hexyl cinnamic aldehyde, hydrocarbons like Limolene, d-Limonene, esters like Hercolyn D, benzyl salicylate, hexyl salicylate, triethyl citrate, iso propyl myristate, or mixtures thereof, or hydrophobic perfume composition preferably incorporating one or more of these raw materials.
  • Typical hydrophobic solvents include diethyl phthalate, ethers like butoxypropoxypropanol, and mixtures thereof.
    Also suitable for use herein are the finished perfume compositions which have hydrophobic properties.
  • Typical of materials that are in hydrophilic form include alcohols like methanol, ethanol, dipropyleneglycol, water, nonionic surfactants as above described but having a melting point below 30C, or mixtures thereof.
  • Preferred carrier materials are selected from benzyl salicylate, diethyl phatalate, dipropylene glycol, methanol, ethanol, and mixtures thereof.
  • Typically when the amine reaction product is only mixed with a carrier but not further processed, the amine reaction product will be present in an amount of from 1 to 75%, preferably 10 to 60%, more preferably 15 to 45% by weight of the processed reaction product. In this instance, the amount of carrier will be sufficient to add up to 100%. Of course, the processed amine reaction product may also contain minors but in quantities which will not exceed the amount of carrier material. Typically the carrier will be present in an amount of from 3 to 95%, preferably from 15 to 90% and most preferably from 45 to 85%, by weight of the processed amine reaction product.
  • By processed amine reaction product, it is meant the resulting product of the amine reaction product with the carrier material.
  • Processing of the amine reaction product with the carrier is done by thoroughly mixing the amine reaction product with the carrier. Advantageously, there is no need for additional ingredients to provide a resulting substantially homogenous mixture. This mixing is done at the lowest possible temperature, i.e. just above the melting point of the carrier or at room temperature. The mixing step is carried out until a complete homogeneous mixture is obtained. By "homogeneous", it is meant compositions which have similar appearance to the resulting composition of a 20g of amine reaction product mixed with 20g of methanol or 80g of diethylphtalate for 5 minutes by means of an Ultra Turrax , the temperature of mixing being room temperature.
  • The obtained processed amine reaction product may then be suitable for spray on applications when use of a liquid carrier is made.
    • Coating agents
  • When use of a carrier with a melting point of less than 30 °C is made for the mixing with the amine reaction product, it may then be preferred to further process the mixture to form a coated particle like e.g. by adsorption of the mixture onto a solid, preferably porous coating. The coating will advantageously protect the processed amine reaction product from the aggressive chemicals present in wash water.
  • The resulting coated particles can be in any form which is suitable for incorporation into liquid or powders, preferably powders, such as agglomerate, pellets, tablets, or mixtures thereof.
  • Suitable coating agents for both solid, including paste, and liquid mixtures are substantially water-soluble solid binder or agglomerating agents.
  • "Substantially water soluble" shall refer to a material that is soluble in distilled (or equivalent) water, at 25°C., at a concentration of 0.2% by weight, and are preferably soluble at 1.0% by weight.
  • A "solid" is defined as a material that is a solid at ambient temperatures, and so solid substantially water-soluble binder or agglomerating agent must have a melting point of at least 30°C, and preferably of at least 40°C.

Polycarboxylates containing three carboxy groups include, in particular, water-soluble citrates, aconitrates and citraconates as well as succinate derivatives such as the carboxymethyloxysuccinates described in British Patent No. 1,379,241, lactoxysuccinates described in British Patent No. 1,389,732, and aminosuccinates described in Netherlands Application 7205873, and the oxypolycarboxylate materials such as 2-oxa-1,1,3-propane tricarboxylates described in British Patent No. 1,387,447.
  • Polycarboxylates containing four carboxy groups include oxydisuccinates disclosed in British Patent No. 1,261,829, 1,1,2,2-ethane tetracarboxylates, 1,1,3,3-propane tetracarboxylates and 1,1,2,3-propane tetracarboxylates. Polycarboxylates containing sulfo substituents include the sulfosuccinate derivatives disclosed in British Patent Nos. 1,398,421 and 1,398,422 and in U.S. Patent No. 3,936,448, and the sulfonated pyrolysed citrates described in British Patent No. 1,439,000.
  • Alicyclic and heterocyclic polycarboxylates include cyclopentane-cis,cis,cis-tetracarboxylates, cyclopentadienide pentacarboxylates, 2,3,4,5-tetrahydrofuran - cis, cis, cis-tetracarboxylates, 2,5-tetrahydrofuran - cis - dicarboxylates, 2,2,5,5-tetrahydrofuran - tetracarboxylates, 1,2,3,4,5,6-hexane - hexacarboxylates and carboxymethyl derivatives of polyhydric alcohols such as sorbitol, mannitol and xylitol.

  • Of the above, the preferred polycarboxylates are hydroxycarboxylates containing up to three carboxy groups per molecule, more particularly citrates.
  • Borate, as well as builders containing borate-forming materials that can produce borate under detergent storage or wash conditions can also be used but are not preferred at wash conditions less that about 50°C, especially less than about 40°C.
  • Examples of carbonates are the alkaline earth and alkali metal carbonates, including sodium carbonate and sesqui-carbonate and mixtures thereof with ultra-fine calcium carbonate as disclosed in German Patent Application No. 2,321,001 published on November 15, 1973.

  • Although less preferred for use herein because of their lower solubility, partially water soluble coating agents may also be used as coating agent. These compounds are indeed less preferred because during the wash cycle the amine reaction product will still be at least partially coated and therefore can not display its full functionality of long lasting freshness on dry fabrics or hard surfaces. Examples of partially water soluble coating agents include the crystalline layered silicates. Examples of largely water insoluble builders include the sodium aluminosilicates.
  • Crystalline layered sodium silicates have the general formula NaMSixOx+1.yH2O wherein M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20. Crystalline layered sodium silicates of this type are disclosed in EP-A-0164514 and methods for their preparation are disclosed in DE-A-3417649 and DE-A-3742043. For the purpose of the present invention, x in the general formula above has a value of 2, 3 or 4 and is preferably 2. The most preferred material is δ-Na2Si2O5, available from Hoechst AG as NaSKS-6.
  • Suitable aluminosilicate zeolites have the unit cell formula Naz[(AlO2)z(SiO2)y]. XH2O wherein z and y are at least 6; the molar ratio of z to y is from 1.0 to 0.5 and x is at least 5, preferably from 7.5 to 276, more preferably from 10 to 264. The aluminosilicate material are in hydrated form and are preferably crystalline, containing from 10% to 28%, more preferably from 18% to 22% water in bound form.

  • Typically when the amine reaction product is mixed with a carrier and further processed to form a coated particle, the amine reaction product will be present in an amount of from 1 to 75%, preferably 5 to 30%, more preferably 6 to 25% by weight of the processed reaction product in the produced particle.
  • Typically the coating agent will be present in an amount of from 10% to 95%, preferably from 30 to 90%, more preferably, 50 to 75% by weight of the particle of the processed amine reaction product. In this instance, the amount of carrier will be sufficient to add up to 100%. Of course, the coated particle may also contain minors but in quantities which will not exceed either of the amount of carrier material or coating agent.
  • Preferred coating materials are selected from carbonate, starch, cyclodextrin, sulfate salts, silicates, and mixtures thereof.
  • The surface treatment of the particle can be carried out in a number of ways using equipment known in the art and the process may take in batch wise or continuous fashion.
  • One method for applying the coating material involves agglomeration. Any conventional agglomerator/mixer may be used including, but not limited to pan, rotary drum and vertical blender types. Molten coating compositions may also be applied either by being poured onto, or spray atomized onto a moving bed of the mixture of amine reaction product with carrier.
  • Another method for applying the coating is to pour the obtained mixture (so-called particle), as herein before described, onto the coating material and agglomerate it in a Braun Mixer. Care is also taken that the temperature during the mixing and/or coating step does not substantially exceed the melting point of the carrier material. For example, 50g of a mixture containing a hydrophobic perfume composition and 25g of the amine reaction product is poured at room temperature into a Braun Mixer containing 200g of starch. The mixing of the ingredients is carried out for about 5 minutes.
  • Once the coated particle is obtained, it may be useful to remove the carrier. Such removal can be made by conventional techniques. One typical of these technique is vacuum drying. By removal of the carrier, in particular with liquid carrier having a boiling point between 5 and 200°C, the original viscosity of the amine reaction product, i.e. higher viscosity, in the coated particle is restored which as a result gives a better stability of the coated particle towards the wash liquor environment. The coated particle can then be used as is for incorporation into the finished composition.
  • Accordingly, there is provided a processed amine reaction product as obtainable by the process of the invention.
  • If desired, the coated particle may also contain one or more additional ingredients like a surfactant for improved solubility or dispersability. Typical of such surfactant are the anionic, nonionic, or cationic surfactants. a cationic, anion or non-ionic surfactant like. Preferably, the weight ratio of such additional ingredient(s) to the coating agent is of up to 1:1.
  • In another preferred marketing execution, an additional coating on the coated particle can be provided, which depending on the nature of this additional coating will give improved storage stability, flowability and/or improved fabric substantivity of the coated particle. One typical example is polyvinyl alcohol.
    • Incorporation into finished composition
  • The finished compositions aspect of the invention, including laundry compositions, hard surface cleaning compositions, personal cleaning compositions, comprises the incorporation of the hereinbefore described processed amine reaction product together with one or more laundry or cleaning ingredient in a finished composition. Laundry compositions of the invention, which also encompass compositions providing color care, are suitable for use in any steps of the domestic treatment, that is as a pre-treatment composition, as a wash additive as a composition suitable for use in the rinse-cycle of the laundry cycle or applied on a dryer-sheet. Obviously, multiple applications can be made such as treating the fabric with a pre-treatment composition of the invention and also thereafter with a composition of the invention suitable for use in the rinse cycle and/or suitable for use as a dryer-sheet.
  • As mentioned hereinbefore, the incorporation of the processed amine reaction product is conveniently made depending on its end form by either by spraying when in sprayable liquid form, or dry-addition when in coated form.
  • Laundry compositions encompass laundry detergent compositions, including liquid, solid form like powdered, tablets as well as softening compositions including rinse added softening composition as well as dryer added softening compositions.
  • A conventional disclosure of softening ingredients to be used in the softening composition of the invention can be found in EP 98870227.0, incorporated herein by reference.
  • Finished compositions incorporating the processed amine reaction product will normally contain from 0.001 to 25%, more preferably from 0.02 to 10%, and most preferably from 0.05 to 5% of the processed product on a composition weight basis.

    • Clay
  • The compositions of the invention may preferably contain a clay, preferably present at a level of from 0.05% to 40%, more preferably from 0.5% to 30%, most preferably from 2% to 20% by weight of the composition. For clarity, it is noted that the term clay mineral compound, as used herein, excludes sodium aluminosilicate zeolite builder compounds, which however, may be included in the compositions of the invention as optional components.
  • One preferred clay may be a bentonite clay. Highly preferred are smectite clays, as for example disclosed in the US Patents No.s 3,862,058 3,948,790, 3,954,632 and 4,062,647 and European Patents No.s EP-A-299,575 and EP-A-313,146 all in the name of the Procter and Gamble Company.
  • The term smectite clays herein includes both the clays in which aluminium oxide is present in a silicate lattice and the clays in which magnesium oxide is present in a silicate lattice. Typical smectite clay compounds include the compounds having the general formula Al2(Si2O5)2(OH)2.nH2O and the compounds having the general formula Mg3(Si2O5)2(OH)2.nH2O. Smectite clays tend to adopt an expandable three layer structure.
  • Specific examples of suitable smectite clays include those selected from the classes of the montmorillonites, hectorites, volchonskoites, nontronites, saponites and sauconites, particularly those having an alkali or alkaline earth metal ion within the crystal lattice structure. Sodium or calcium montmorillonite are particularly preferred.
  • Suitable smectite clays, particularly montmorillonites, are sold by various suppliers including English China Clays, Laviosa, Georgia Kaolin and Colin Stewart Minerals.
  • Clays for use herein preferably have a particle dimension of from 10nm to 800nm more preferably from 20nm to 500 mm, most preferably from 50nm to 200 mm.
  • Particles of the clay mineral compound may be included as components of agglomerate particles containing other detergent compounds. Where present as such components, the term "largest particle dimension" of the clay mineral compound refers to the largest dimension of the clay mineral component as such, and not to the agglomerated particle as a whole.
  • Substitution of small cations, such as protons, sodium ions, potassium ions, magnesium ions and calcium ions, and of certain organic molecules including those having positively charged functional groups can typically take place within the crystal lattice structure of the smectite clays. A clay may be chosen for its ability to preferentially absorb one cation type, such ability being assessed by measurements of relative ion exchange capacity. The smectite clays suitable herein typically have a cation exchange capacity of at least 50 meq/100g. U.S. Patent No. 3,954,632 describes a method for measurement of cation exchange capacity.
  • The crystal lattice structure of the clay mineral compounds may have, in a preferred execution, a cationic fabric softening agent substituted therein. Such substituted clays have been termed 'hydrophobically activated' clays. The cationic fabric softening agents are typically present at a weight ratio, cationic fabric softening agent to clay, of from 1:200 to 1:10, preferably from 1:100 to 1:20. Suitable cationic fabric softening agents include the water insoluble tertiary amines or dilong chain amide materials as disclosed in GB-A-1 514 276 and EP-B-0 011 340.

Preferred humectants are organic compounds, including propylene glycol, ethylene glycol, dimers or trimers of glycol, most preferably glycerol. The particle is preferably an agglomerate. Alternatively, the particle may be such that the wax or oil and optionally the humectant form an encapsulate on the clay or alternatively, the clay be a encapsulate for the wax or oil and the humectant. It may be preferred that the particle comprises an organic salt or silica or silicate.
  • However, in another embodiment of the invention, the clay is preferably mixed with one or more surfactants and optionally builders and optionally water, in which case the mixture is preferably subsequently dried. Preferably, such a mixture is further processed in a spray-drying method to obtain a spray dried particle comprising the clay.
  • It may be preferred that the flocculating agent is also comprised in the particle or granule comprising the clay.
  • It may also be preferred that the intimate mixture comprises a chelating agent.

  • The clay flocculating agent functions such as to bring together the particles of clay compound in the wash solution and hence to aid their deposition onto the surface of the fabrics in the wash. This functional requirement is hence different from that of clay dispersant compounds which are commonly added to laundry detergent compositions to aid the removal of clay soils from fabrics and enable their dispersion within the wash solution.
  • Preferred as clay flocculating agents herein are organic polymeric materials having an average weight of from 100,000 to 10,000,000, preferably from 150,000 to 5,000,000, more preferably from 200,000 to 2,000,000.

Suitable bicarbonates to be used herein include any alkali metal salt of bicarbonate like lithium, sodium, potassium and the like, amongst which sodium and potassium bicarbonate are preferred. However, the choice of carbonate or bicarbonate or mixtures thereof may be made depending on the pH desired in the aqueous medium wherein the granules are dissolved. For example where a relative high pH is desired in the aqueous medium (e.g., above pH 9.5) it may be preferred to use carbonate alone or to use a combination of carbonate and bicarbonate wherein the level of carbonate is higher than the level of bicarbonate. The inorganic alkali and/ or earth alkali carbonate salt of the compositions of the invention comprises preferably a potassium or more preferably a sodium salt of carbonate and/ or bicarbonate. Preferably, the carbonate salt comprises sodium carbonate, optionally also a sodium bicarbonate.

In solid detergent compositions of the invention, they may also completely or partially be present in detergent granules such as agglomerates or spray dried granules.
  • In one embodiment of the invention, an effervescence source is present, preferably comprising an organic acid, such as carboxylic acids or aminoacids, and a carbonate. Then it may be preferred that part or all of the carbonate salt herein is premixed with the organic acid, and thus present in an separate granular component.
  • Preferred effervescent source are selected from compressed particles of citric acid and carbonate optionally with a binder; and particle of carbonate, bicarbonate and malic or maleic acid in weight ratios of 4:2:4. The dry add form of citric acid and carbonate are preferably used.

    • Method of use
  • Also provided herein is a method for providing a delayed release of an active ketone or aldehyde which comprises the step of contacting the surface to be treated with a compound or composition of the invention, and thereafter contacting the treated surface with a material, preferably an aqueous medium like moisture or any other means susceptible of releasing the perfume from the amine reaction product.
  • By "surface", it is meant any surface onto which the compound can deposit. Typical examples of such material are fabrics, hard surfaces such as dishware, floors, bathrooms, toilet, kitchen and other surfaces in need of a delayed release of a perfume ketone and/or aldehyde such as that with litter like animal litter. Preferably, the surface is selected from a fabric, a tile, a ceramic; more preferably is a fabric.
  • By "delayed release" is meant release of the active component (e.g perfume) over a longer period of time than by the use of the active (e.g., perfume) itself.
  • Still in another aspect of the invention, there is provided the use of the product of the invention for the manufacture of a laundry and/or cleaning composition for delivering residual fragrance and fabric care, in particular color care, onto the fabrics on which it is applied.
  • The following are synthesis examples of compounds as defined in the present invention:
    • I-Synthesis of ethyl 4-aminobenzoate with 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde
  • To an ice cooled stirred solution of 10 g of 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde (0.07 mol) in 35 mL EtOH and molecular sieves (4Å, 20 g) 1eq of the amine was added via an addition funnel. The reaction mixture was stirred under nitrogen atmosphere and protected from light. After 6 days the mixture was filtrated and the solvent was removed. The yield of imine formation is about 90%.
  • Similar results were obtained where the 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde was replaced by bourgeonal, trans-2-nonenal, or trans-2-hexenal.
    • II-Synthesis of 1,4-bis-(3-aminopropyl)-piperazine with α-Damascone
  • In order to substitute both primary amine groups with a perfume, 2eq of perfume were used for 1eq of amino functional polymer. To an ice cooled stirred solution of 1mmol of α-Damascone in 6 mL EtOH and molecular sieves (4Å, 20 g), 0.5eq of 1,4-bis-(3-aminopropyl)-piperazine was added via an addition funnel. The reaction mixture was stirred under nitrogen atmosphere and protected from light. After the disappearance of the absorption peak from the NMR spectrum of the free perfume raw material (from 3 to 16 hours), the mixture was filtrated and the solvent was removed by vacuum distillation. The yield of β-aminoketone formation is about 90%.
  • Similar results were obtained where the α-Damascone was replaced by 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde, vertocitral, bourgeonal, δ-Damascone or citronellal. In these instances, Schiff-bases are formed.
    • III-Synthesis of Lupasol with Damascones and 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde
  • The β-amino ketone from Lupasol G100 (commercially available from BASF with a content of 50 % water, 50 % Lupasol G100 (Mw. 5000)) and α-Damascone (or δ-Damascone) was prepared using any one of these three different procedures described as follows:
  • 1. Commercially available Lupasol G100 was dried using the following procedure: 20 g of the Lupasol solution was dried at the rotating evaporator during several hours. The obtained residue, still containing about 4.5 g of H2O, was azeotropically distilled at the rotating evaporator using toluene. The residue was then placed in the desiccator dried at 60 °C (using P2O5 as water absorbing material). On basis of the obtained weight we concluded that the oil contained less then 10 % H2O. On basis of the NMR-spectra we concluded that this is probably less then 5 %. This dried sample was then used in the preparation of β-amino ketones. 1.38 g of the dried Lupasol G100 obtained above was dissolved in 7 ml. ethanol. The solution was stirred gently with a magnetic stirrer during a few minutes before 2 g Na2SO4 (anhydrous) was added. After stirring again for a few minutes 2.21 g α-Damascone was added over a period of 1 minute. After two days reaction, the mixture was filtrated over a Celite filter (vide supra), and the residue washed thoroughly with ethanol. About 180 ml. of a light foaming filtrate was obtained. This was concentrated until dryness using a rotating evaporator and dried over P2O5 in an desiccator at room temperature. About 3.5 of a colorless oil was obtained.
  • 2. 4.3 g Lupasol G100 solution was without drying dissolved in 10 ml. ethanol. The solution was stirred with a magnetic stirrer during a few minutes before 3.47 g α-Damascone was added over a 1.5 minutes period. After two days reaction at room temperature the reaction mixture was filtrated over Celite (vide supra) and the residue washed thoroughly with ethanol. The filtrate (200 ml., light foaming) was concentrated at the evaporator and dried in an desiccator (P2O5 as drying agent) at room temperature. About 5.9 g of a colorless oil was obtained.
  • 3. To 3.0 g of Lupasol G100 solution (used as such) was added 2.41 g α-Damascone. The mixture was stirred without using solvent. After stirring for 4 days the obtained oil was dissolved in 100 ml. THF, dried with MgSO4, filtrated and the filtrate concentrated at the rotating evaporator. After drying in the desiccator (P2O5) at room temperature about 4 g of a colorless oil was obtained. This oil still contained about 13 % (w/w) of THF, even after a prolonged drying (3 days).
  • The product obtained from the three procedures had identical NMR-spectra.
  • Similar results are obtained where Lupasol G35 or Lupasol HF is used instead of Lupasol G100.
  • Similar results were obtained where the α-Damascone was replaced by 2,4-dimethyl-3-cyclohexen-1-carboxaldehyde.
  • Still another possible route of synthesis is by using Lupasol P. The β-amino ketone from Lupasol P and α-Damascone was prepared using the procedure described as follows:
  • 1.8g Lupasol P solution (50 % H2O, 50 % Lupasol Mw. 750000, as obtained from BASF) was dissolved in 7 ml ethanol, the solution was stirred for a few minutes with a magnetic stirrer before 1.44 g α-Damascone was added. After three days the reaction mixture was filtrated over a celite filter (vide supra) and the residue washed thoroughly with ethanol. After concentrating of the filtrate and drying of the obtained oil in the desiccator (P2O5) at room temperature, about 3 g of the reaction product between Lupasol and α-Damascone was obtained.
    • Processing method 1)-Processing method for spray-on
  • Processing of the amine reaction product with the carrier is done as hereinbefore described. In particular, 20g of amine reaction product as above synthesised is mixed with 10 to 80g of a carrier, e.g. hydrophobic perfume composition, dipropylene glycol, diethylphthalate in an Ultra Turrax until an homogenous mixture is obtained. The temperature of mixing is about room temperature, and the speed of the mixer is sufficient to maintain such temperature substantially constant. Temperature and time will depend on the nature of the carrier but are a conventional step to skilled man. Of course, the amount of carrier relative to the amine reaction product will depends on the desired sprayability and the end viscosity of the resulting mixture. In the examples of the present invention, the viscosity was below 500Cps, as measured on a rheometer, TA Instrument CSL2 100 at a temperature of 25C with a gap setting of 500 microns.
    • 2)-Processing method for coating
  • Processing of the amine reaction product with the carrier is done as hereinbefore described. In particular, 20g of amine reaction product as above synthesised is mixed in an Ultra Turrax containing 20g of carrier, e.g. methanol or perfume mixture or composition for 5 minutes, the temperature of mixing being to about room temperature, and the speed of the mixer being sufficient so as to maintain such temperature substantially constant. Temperature and time will depend on the nature of the carrier but are a conventional step to skilled man.
  • When use of a perfume mixture is made, the composition in % by weight of a typical hydrophobic perfume mixture is as follows:
    Citronellol 7
    Geraniol 7
    Linalool 7
    Para Tertiary Butyl Cyclohexyl Acetate 10
    Phenyl Ethyl Alcohol 19
    Habanolide 4.5
    Para Methoxy Acetophenone 1.5
    Benzyl Acetate 4
    Eugenol 2
    Phenyl Ethyl Acetate 5
    Verdyl Acetate 6
    Verdyl Propionate 4
    Hexyl Cinnamic Aldehyde 3
    lonone Gamma Methyl 2
    Methyl Cedrylone 10
    P.T. Bucinal 7
    Para Cresyl Methyl Ether 1
  • When desired, the obtained processed amine reaction product from above is subsequently coated. In particular, the resulting mixture is maintained at a temperature substantially equal to the melting point of the carrier material and poured onto the coating material and agglomerated in an electrical mixer like a Braun Mixer. Care is also taken that the temperature during the mixing does not substantially exceed the melting point of the carrier material. For example, 100g of a mixture containing the methanol or perfume mixture and 20g of the amine reaction product is poured at room temperature into a Braun Mixer containing 300g of carbonate. The mixing of the ingredients is carried out for about 5 minutes. Again, temperature and time will depend on the nature of the coating agent but are conventional step to skilled man.
  • Once the coated particle is obtained, it may be desired to remove the methanol by vacuum distillation.
