Definitions
- the present invention relates to a consumer product comprising a container, spray applicator and a liquid laundry treatment composition.
- low active or 'mild' spray formulations can overcome such issues. Items to be washed are sprayed with the spray formulation and then added into the wash process, for example into an automatic washing machine, without the need for any further detergent to be added.
- the spray application spreads the detergent composition over the fabric minimizing as such local product excess hence risk of potential local damage, and reduces the overall amount of treatment composition to be used and hence leads to reduced amount of water required in a rinse operation hence rinsing time requirement. As such short or delicate cycles or even just rinse cycles might already fulfill the need.
- the low active formulation provides a 'less harsh' treatment of the fabrics whilst still providing sufficient cleaning and/or refreshing of garments.
- GB2353287A discloses a detergent composition comprising 0.2-10wt% surfactant combination of anionic surfactant and nonionic surfactant in combination with a spray mechanism.

- Dv 50% average particle size
- liquid laundry treatment composition refers to any laundry treatment composition that is a liquid and is capable of wetting and treating fabric e.g., cleaning clothing in a domestic washing machine.
- the liquid composition can include solids or gases in suitably subdivided form, but the liquid composition excludes forms which are non-fluid overall, such as tablets or granules.
- the laundry treatment composition may be a laundry detergent composition, a laundry softening composition, a laundry care composition, a laundry scent refresher composition or a mixture thereof.
- the laundry treatment composition has both cleaning, refreshing and care properties, the latter including fabric softness and fabric shape and texture retention properties.
- the liquid laundry treatment composition comprises at least 80% by weight of the liquid laundry detergent composition of water. Such water levels are preferred to enable a 'less harsh' composition and also allow for easy spray application.
- the liquid laundry treatment composition comprises between 5% and 10% by weight of the liquid laundry treatment composition of non-soap surfactant.
- the non-soap surfactant is described in more detail below.
- the liquid laundry treatment composition comprises between 0.3% to 0.7% by weight of the liquid laundry treatment composition of a cationic polymer,
- the cationic polysaccharide technology will further provide fabric conditioning benefits including softness and multi-cycle shape retention benefits.
- the cationic polymer is a hydroxyethyl cellulose derivatised with trimethyl ammonium substituted epoxide.
- hydrophobically modified we herein mean that one or more hydrophobic groups are bound to the polymer.
- cationically modified we herein mean that one or more cationically charged groups are bound to the polymer.
- the cationically modified hydroxyethyl cellulose preferably is hydroxyethyl cellulose derivatised with trimethyl ammonium substituted epoxide.
- the cationic polysaccharide polymer can be synthesized in, and are commercially available in, a number of different molecular weights. In order to achieve optimal softening and care performance from the product, it is desirable that the cationic polymer used in this invention be of an appropriate molecular weight. Without wishing to be bound by theory, it is believed that polymers that are too high in mass can entrap soils and prevent them from being removed, as well as will be providing physical stability challenges especially in low viscous liquors required for spraying.
- cationic polymers with an average molecular weight of less than about 850,000 daltons, and especially those with an average molecular weight of less than 500,000 daltons can help to minimise this effect without significantly reducing the softening performance of properly formulated products while providing the desired optimum spray pattern.
- polymers with a molecular weight of about 10,000 daltons or less are believed to be too small to give an effective softening benefit.
- the cationic polymer according to the invention preferably has a molecular weight of from about 10,000 daltons to about 850,000 daltons, preferably from about 50,000 daltons to about 750,000 daltons, more preferably from about 100,000 daltons to about 600,000 daltons, most preferably from about 200,000 daltons to about 500,000 daltons.
- the cationic polymers according to the invention may also have a cationic charge density ranging from about 0.1meq/g to about 5meq/g, preferably from about 0. 15meq/g to about 4 meq/g, more preferably from about 0.2meq/g to about 2.5 meq/g, even more preferably from about 0.25meq/g to about 1.5 meq/g, most preferably from about 0.25 meq/g to about 0.7 meq/g, at the pH of intended use of the laundry composition.
- charge density of the cationic polymers is defined as the number of cationic sites per polymer gram atomic weight (molecular weight), and can be expressed in terms of meq/gram of cationic charge.
- cationic polymers with a too high charge density are thought to be too sensitive to precipitate out with anionic compounds in the formulation, while cationic polymers with a too low charge density are thought to have a too low affinity to fabrics, compromising softness accordingly.
- Any anionic counterions can be used in association with cationic polymers.
- Non-limiting examples of such counterions include halides (e.g. chlorine, fluorine, bromine, iodine), sulphate and methyl sulfate, preferably halides, more preferably chlorine.
- the cationic polymer according to the invention might be "hydrophobically modified".
- hydrophobic groups are bound to the polymer. Without intending to be bound by theory we believe that hydrophobic modification can increase the affinity of the polymer towards the fabric.
- the one or more hydrophobic groups can be independently selected from C 1 -C 32 preferably C 5 -C 32 alkyl; C 1 -C 32 preferably C 5 -C 32 substituted alkyl, C 5 -C 32 alkylaryl, or C 5 -C 32 substituted alkylaryl, (poly)alkoxy C 1 -C 32 preferably C 5 -C 32 alkyl or (poly)alkoxy substituted C 1 -C 32 preferably C 5 -C 32 alkyl or mixtures thereof.
- Hydrophobic substitution on the polymer, preferably on the anhydroglucose rings of the cationic polymer may range from 0.01% to 5% per glucose unit, more preferably from 0.05% to 2% per glucose unit, of the polymeric material.
- the cationic polysaccharide polymers according to the invention include those which are commercially available and further include materials which can be prepared by conventional chemical modification of commercially available materials.
- Commercially available cationic cellulose polymers according to the invention include those with the INCI name Polyquaternium 10, such as those sold under the trade names: Ucare Polymer JR 30M, JR 400, JR 125, LR 400 and LK 400 polymers; Polyquaternium 67 such as those sold under the trade name Softcat SK TM , all of which are marketed by Amerchol Corporation, Edgewater NJ; and Polyquaternium 4 such as those sold under the trade name: Celquat H200 and Celquat L-200, available from National Starch and Chemical Company, Bridgewater, NJ.
- polysaccharides include hydroxyethyl cellulose or hydoxypropylcellulose quaternized with glycidyl C 12 -C 22 alkyl dimethyl ammonium chloride.
- suitable polysaccharides include the polymers with the INCI names Polyquaternium 24 such as those sold under the trade name Quaternium LM 200 by Amerchol Corporation, Edgewater NJ.
- synthetic derived cationic polymers can also be used within the scope of the application.
- the liquid laundry treatment composition may comprise less than 10%, preferably less than 8%, more preferably less than 5%, even more preferably less than 3%, most preferably between 0.5% and 2% by weight of the laundry treatment composition of fatty acid, neutralised fatty acid soap or a mixture thereof.
- a low level of fatty acid will enable faster wash suds to collapse during washing and upon rinsing, as such reducing risk of leaving detergent residues behind while maximizing active cleaning surfactant presence during the wash.
- a too high level of fatty acid though risks leaving calcium fatty acids deposits behind in presence of hard water and as such is not preferred.
- cleaning performance boosting technologies into the consumer product of the invention, enabling the formulator to keep overall surfactant levels low, facilitating suds control hence residue risk accordingly.
- a range of possible performance boosting technologies are described below.

- they may help to protect the surfactant system against water hardness by complexing calcium and magnesium ions present in the wash liquor.
- the laundry treatment composition preferably comprises between 0.01% and 3%, preferably between 0.025% and 2%, more preferably between 0.05% and 1.5% by weight of the laundry treatment composition of a soil release polymer, a polyethyleneimine preferably an alkoxylated polyethyleneimine, a zwitterionic polyamine or a mixture thereof.

Description
- The present invention relates to a consumer product comprising a container, spray applicator and a liquid laundry treatment composition.
- Laundry wash operations and the use of laundry treatment compositions are well known.
- However, for some wash operations, such as delicate garments, lightly soiled garments, or garments simply in need of a 'refresh' (maybe after being hung in a wardrobe for a period of time), current wash practices can be wasteful in terms of resource and environmentally unfriendly. Furthermore, consumers typically would prefer to wash these delicate items in isolation or with a very few items solely, this in order to further reduce the risk of damage due to inter-garment friction. In other words, the volume of wash composition, full washing loads and full wash cycles are not needed nor desired to achieve the desired benefit. In addition, with respect to the garments themselves, especially delicate garments, current wash process can be quite harsh on said garments.
- For such applications it was found that low active or 'mild' spray formulations can overcome such issues. Items to be washed are sprayed with the spray formulation and then added into the wash process, for example into an automatic washing machine, without the need for any further detergent to be added. The spray application spreads the detergent composition over the fabric minimizing as such local product excess hence risk of potential local damage, and reduces the overall amount of treatment composition to be used and hence leads to reduced amount of water required in a rinse operation hence rinsing time requirement. As such short or delicate cycles or even just rinse cycles might already fulfill the need. The low active formulation provides a 'less harsh' treatment of the fabrics whilst still providing sufficient cleaning and/or refreshing of garments.
- However, an issue encountered with such formulations is that as the fabric treatment composition is sprayed directly on delicate clothes, local accumulation of chemistry on the fabrics may occur. Furthermore, if the spraying pattern is too concentric, this may motivate the consumer to spray more than needed to get the entire fabric surface area covered with the composition. This would again unnecessarily increase the amount of chemistry through the wash, rendering the overall treatment 'more harsh' again, and might eventually require more rinsing water and rinsing time again.
- Therefore, there is a need to provide a consumer product comprising a spray applicator and a low active laundry treatment composition wherein the composition can be sprayed as a broad fine dispersion of droplets onto fabrics, preferably without impacting performance of the composition.
- It was surprisingly found that the careful balance of non-soap anionic surfactant to nonionic surfactant in the laundry treatment composition provided for such broader spray patterns whilst still providing a laundry treatment composition capable of being sprayed and providing laundry treatment benefits.

The spray dispenser can be a pre-compression sprayer or an aerosol spray with a pressure control valve, both commercially available in the art.

- The term 'liquid laundry treatment composition' refers to any laundry treatment composition that is a liquid and is capable of wetting and treating fabric e.g., cleaning clothing in a domestic washing machine. The liquid composition can include solids or gases in suitably subdivided form, but the liquid composition excludes forms which are non-fluid overall, such as tablets or granules.
- The laundry treatment composition may be a laundry detergent composition, a laundry softening composition, a laundry care composition, a laundry scent refresher composition or a mixture thereof. Preferably the laundry treatment composition has both cleaning, refreshing and care properties, the latter including fabric softness and fabric shape and texture retention properties.
- The liquid laundry treatment composition comprises at least 80% by weight of the liquid laundry detergent composition of water. Such water levels are preferred to enable a 'less harsh' composition and also allow for easy spray application.
- The liquid laundry treatment composition comprises between 5% and 10% by weight of the liquid laundry treatment composition of non-soap surfactant.
- The non-soap surfactant is described in more detail below.
- The liquid laundry treatment composition comprises between 0.3% to 0.7% by weight of the liquid laundry treatment composition of a cationic polymer, The cationic polysaccharide technology will further provide fabric conditioning benefits including softness and multi-cycle shape retention benefits.
- The cationic polymer is a hydroxyethyl cellulose derivatised with trimethyl ammonium substituted epoxide.
- By "hydrophobically modified" we herein mean that one or more hydrophobic groups are bound to the polymer. By "cationically modified" we herein mean that one or more cationically charged groups are bound to the polymer.
- The cationically modified hydroxyethyl cellulose preferably is hydroxyethyl cellulose derivatised with trimethyl ammonium substituted epoxide.
- The cationic polysaccharide polymer can be synthesized in, and are commercially available in, a number of different molecular weights. In order to achieve optimal softening and care performance from the product, it is desirable that the cationic polymer used in this invention be of an appropriate molecular weight. Without wishing to be bound by theory, it is believed that polymers that are too high in mass can entrap soils and prevent them from being removed, as well as will be providing physical stability challenges especially in low viscous liquors required for spraying. The use of cationic polymers with an average molecular weight of less than about 850,000 daltons, and especially those with an average molecular weight of less than 500,000 daltons can help to minimise this effect without significantly reducing the softening performance of properly formulated products while providing the desired optimum spray pattern. On the other hand, polymers with a molecular weight of about 10,000 daltons or less are believed to be too small to give an effective softening benefit. Therefore, the cationic polymer according to the invention preferably has a molecular weight of from about 10,000 daltons to about 850,000 daltons, preferably from about 50,000 daltons to about 750,000 daltons, more preferably from about 100,000 daltons to about 600,000 daltons, most preferably from about 200,000 daltons to about 500,000 daltons.
- The cationic polymers according to the invention may also have a cationic charge density ranging from about 0.1meq/g to about 5meq/g, preferably from about 0. 15meq/g to about 4 meq/g, more preferably from about 0.2meq/g to about 2.5 meq/g, even more preferably from about 0.25meq/g to about 1.5 meq/g, most preferably from about 0.25 meq/g to about 0.7 meq/g, at the pH of intended use of the laundry composition. As used herein the "charge density" of the cationic polymers is defined as the number of cationic sites per polymer gram atomic weight (molecular weight), and can be expressed in terms of meq/gram of cationic charge. In general, adjustments of the proportions of amine or quaternary ammonium moieties in the polymer in function of the pH of the liquid laundry formulation in the case of amines, will affect the charge density. Without intending to be bound by theory, cationic polymers with a too high charge density are thought to be too sensitive to precipitate out with anionic compounds in the formulation, while cationic polymers with a too low charge density are thought to have a too low affinity to fabrics, compromising softness accordingly. Any anionic counterions can be used in association with cationic polymers. Non-limiting examples of such counterions include halides (e.g. chlorine, fluorine, bromine, iodine), sulphate and methyl sulfate, preferably halides, more preferably chlorine.
- The cationic polymer according to the invention might be "hydrophobically modified". We herein mean that one or more hydrophobic groups are bound to the polymer. Without intending to be bound by theory we believe that hydrophobic modification can increase the affinity of the polymer towards the fabric. Without intending to be limiting, the one or more hydrophobic groups can be independently selected from C1-C32 preferably C5-C32 alkyl; C1-C32 preferably C5-C32 substituted alkyl, C5-C32 alkylaryl, or C5-C32 substituted alkylaryl, (poly)alkoxy C1-C32 preferably C5-C32 alkyl or (poly)alkoxy substituted C1-C32 preferably C5-C32 alkyl or mixtures thereof. Hydrophobic substitution on the polymer, preferably on the anhydroglucose rings of the cationic polymer may range from 0.01% to 5% per glucose unit, more preferably from 0.05% to 2% per glucose unit, of the polymeric material.
- The cationic polysaccharide polymers according to the invention include those which are commercially available and further include materials which can be prepared by conventional chemical modification of commercially available materials. Commercially available cationic cellulose polymers according to the invention include those with the INCI name Polyquaternium 10, such as those sold under the trade names: Ucare Polymer JR 30M, JR 400, JR 125, LR 400 and LK 400 polymers; Polyquaternium 67 such as those sold under the trade name Softcat SK ™, all of which are marketed by Amerchol Corporation, Edgewater NJ; and Polyquaternium 4 such as those sold under the trade name: Celquat H200 and Celquat L-200, available from National Starch and Chemical Company, Bridgewater, NJ. Other suitable polysaccharides include hydroxyethyl cellulose or hydoxypropylcellulose quaternized with glycidyl C12-C22 alkyl dimethyl ammonium chloride. Examples of such polysaccharides include the polymers with the INCI names Polyquaternium 24 such as those sold under the trade name Quaternium LM 200 by Amerchol Corporation, Edgewater NJ.
- Alternatively, synthetic derived cationic polymers can also be used within the scope of the application.
- The liquid laundry treatment composition may comprise less than 10%, preferably less than 8%, more preferably less than 5%, even more preferably less than 3%, most preferably between 0.5% and 2% by weight of the laundry treatment composition of fatty acid, neutralised fatty acid soap or a mixture thereof. Without wishing to be bound by theory, a low level of fatty acid will enable faster wash suds to collapse during washing and upon rinsing, as such reducing risk of leaving detergent residues behind while maximizing active cleaning surfactant presence during the wash. A too high level of fatty acid though risks leaving calcium fatty acids deposits behind in presence of hard water and as such is not preferred.
- It will be highly preferred to add cleaning performance boosting technologies into the consumer product of the invention, enabling the formulator to keep overall surfactant levels low, facilitating suds control hence residue risk accordingly. A range of possible performance boosting technologies are described below.
- The laundry treatment composition may comprise less than 3%, preferably less than 2%, more preferably less than 1%, even more preferably between 0.01% and 0.5%, most preferably between 0.05% and 0.3% by weight of the laundry treatment composition of a chelant, preferably wherein the chelant is selected from amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof, preferably selected from the group consisting of glutamic-N,N-diacetic acid (GLDA), methyl-glycine-diacetic acid (MGDA), Diethylenetriamine penta methylphosphonic acid (DTPMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP), ethylenediaminetetra-acetates (EDTA), N-hydroxyethylethylenediaminetriacetates, nitrilo-triacetates (NTA), ethylenediamine tetrapro-prionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, aspartic acid-N-monoacetic acid (ASMA), aspartic acid-N,N-diacetic acid (ASDA), aspartic acid-N-monopropionic acid (ASMP) , iminodisuccinic acid (IDS), Imino diacetic acid (IDA), N- (2-sulfomethyl) aspartic acid (SMAS), N- (2-sulfoethyl) aspartic acid (SEAS), N- (2- sulfomethyl) glutamic acid (SMGL), N- (2- sulfoethyl) glutamic acid (SEGL), N- methyliminodiacetic acid (MIDA), alanine-N,N-diacetic acid (ALDA) , serine-N,N-diacetic acid (SEDA), isoserine-N,N-diacetic acid (ISDA), phenylalanine-N,N-diacetic acid (PHDA) , anthranilic acid- N ,N - diacetic acid (ANDA), sulfanilic acid-N, N-diacetic acid (SLDA) , taurine-N, N-diacetic acid (TUDA) and sulfomethyl-N,N-diacetic acid (SMDA), ethylenediamine disuccinate ("EDDS"), Hydroxyethyleneiminodiacetic acid, Hydroxyiminodisuccinic acid, Hydroxyethylene diaminetriacetic acid, or a mixture thereof, more preferably the chelant is selected from the group consisting of glutamic-N,N-diacetic acid (GLDA), methyl-glycine-diacetic acid (MGDA) and derivatives thereof, and/or Diethylenetriamine penta methylphosphonic acid (DTPMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP), and derivatives thereof, and mixtures thereof, most preferably Diethylenetriamine penta methylphosphonic acid (DTPMP). Without wishing to be bound by theory, the lower chelant levels are preferred to provide a less harsh laundry treatment composition while still facilitating stain removal especially bleachable stain removal.
- The laundry treatment composition preferably comprise a polycarboxylate, preferably selected from the group of consisting of malonic acid, (ethyl enedioxy) diacetic acid, maleic acid, diglycolic acid, tartaric acid, tartronic acid, fumaric acid, citric acid, more preferably citric acid, wherein the citric acid is preferably present at a level of 0.1% to 5%, preferably from 0.5% to 3% most preferably from 1% to 2% by weight of the liquid treatment composition.

- A spray bottle is placed on a bench at a distance of 20cm between the front exit of the nozzle and the spraying target. The spraying target is a vertical positioned plastic slide used for laser printing (003R98203 - XEROX A3 TRANSPARENCY - PET material), collecting one single spray of detergent composition. An image of the spray pattern is achieved through scanning the sprayed-on plastic slide using a Xerox A3 scanner (Xerox® DocuMate® 4830). The image is consequently analyzed for number of liquid particles (at a lower size threshold for smaller particles of 0.01mm), using publicly available ImageJ Java-based image analysis software developed at the National Institutes of Health. 2 identical spray bottles were used to test the example 1 versus the comparative example formulation. The average values of two replicates are reported.
- The below table summarizes the analyzed spray patterns of the nonionic based surfactant system outside the scope of the invention (Comparative Example 1), compared to a full anionic surfactant system outside the scope of the invention (Example 1). It can clearly be seen that an anionic based surfactant system (Example 1) leads to a more broadly dispersed spray pattern compared to the full nonionic (Comparative Example 1) formulation, as supported by a higher number of sprayed particles despite equal sprayed volume.
