Definitions
- the invention relates to a granular additive for washing and cleaning agents, which consists of two granular powder components of defined composition, on which liquid, semi-solid or solid nonionic surfactants are adsorbed. Both powder components have a porous structure and can absorb up to 30% by weight, based on the additive, of such nonionic surfactants without the free-flowing properties suffering.
- nonionic surfactants have a very high cleaning power, which makes them particularly suitable for use in low-temperature detergents.
- their proportion cannot be increased significantly beyond 8 to 10 percent by weight in the generally customary production of detergents by means of spray drying, since this would otherwise result in excessive smoke formation in the exhaust air from the spray towers and inadequate pouring properties of the spray powder.
- Methods have therefore been developed in which the liquid or melted nonionic surfactant is mixed onto the previously spray-dried powder or sprayed onto a carrier substance.
- water-soluble builder substances in particular spray-dried phosphates, carbonates, bicarbonates, soluble silicates and borates, and water-insoluble builder substances, such as sodium aluminosilicate (zeolite) and silicon dioxide (Aerosil), have been proposed as carriers, but the known agents often have only a limited ad ⁇ sorption capacity as well as certain technical disadvantages.
- zeolite sodium aluminosilicate
- silicon dioxide Aerosil
- phosphates are undesirable because of their eutrophic properties.
- Fine powdered zeolites also have only a limited absorption capacity for liquid substances, while special adsorbents, such as diatomaceous earth and aerosil, as inert components do not contribute to the washing action.
- DE 2418294 discloses detergents which consist of a powder component obtained by hot spray drying and granular sodium perborate tetrahydrate, the latter being impregnated with a defined mixture of nonionic surfactants. Due to the selection of non-ionic surfactants, the granulate is dust-free and free-flowing. According to EP 34 194, the perborate tetrahydrate is treated with nonionic surfactants which contain both ethylene glycol ether groups and propylene glycol ether groups. In addition to good flowability, the granules are notable in particular for being odorless.
- DE 25 07 926 contains examples of the preparation of premixes, powder mixtures of aluminosilicate (zeolite), perborate and optionally also a bleach activator being sprayed with nonionic surfactants.
- the resulting granules are then mixed with other powder components, in particular tower spray powder.
- a certain stickiness of the granules, which can also be transferred to the overall mixture, is a problem here, especially if the admixed tower spray powder contains no phosphates.
- EP 168 102 discloses a process for the production of high-density detergents in which nonionic surfactants are sprayed onto a powder mixture of sodium perborate monohydrate, zeolite and other builder substances.
- the base powder is granulated at the same time.
- Another part of the nonionic surfactants used overall is sprayed onto a second powder component which is free of sodium sulfate and consists of spray-dried granules, the usual surfactants, builder substances and others Contains detergent ingredients.
- Both the perborate-containing base powder and the spray-dried powder component contain considerable amounts of sodium tripolyphosphate in the agents according to the examples.
- absorbent carrier grains which consist of several constituents and are usually produced by spray drying. Examples of these are the agents according to US 3849 327, US 3 886098 and US 3 838 027 and US 4 269 722 (DE 27 42 683).
- these carrier grains which were developed especially for the adsorption of nonionic surfactants, contain considerable amounts of phosphates, which limits their possible uses.
- Phosphate-free carrier grains are known from DE 32 06 265 and DE 32 06 379. They consist essentially of sodium carbonate or hydrogen carbonate, zeolite, sodium silicate, bentonite and polyacrylate. The high proportion of carbonates, however, favors the formation of calcium carbonate in hard water, while the sodium silicate in conjunction with zeolite considerably deteriorates the dispersibility of the grains in water.
- EP 184794 discloses a granular adsorbent which is able to absorb high proportions of liquid to pasty detergent constituents, in particular nonionic surfactants, and (based on anhydrous substance) 60 to 80% by weight of zeolite, 0.1 to 8 % By weight of sodium silicate, 3 to 15% by weight of homo- or copolymers of acrylic acid, methacrylic acid and / or maleic acid, 8 to 18% by weight of water and optionally up to 5% by weight contains nonionic surfactants and can be obtained by spray drying. In practice it has been shown that in washing machines with unfavorably designed washing-in devices, the products do not completely dissolve in the course of the washing-in phase and leave residues.
- EP 425 804 discloses a granular additive for detergents and cleaning agents containing nonionic surfactants, which has improved washing-in behavior and consists of a granular adsorbent (I) and nonionic surfactants (II) adsorbed thereon, where (I) 50 to 75% by weight of finely crystalline zeolite, 2 to 10% by weight of a layered silicate, 3 to 15% by weight of the sodium salt of a (co) polymeric carboxylic acid, optionally up to 10% by weight of sodium sulfate and up to Contains 3% by weight of a surfactant and the rest water and minor constituents and the weight ratio of adsorbent (I) to nonionic surfactants (II) is 2: 1 to 20: 1.
- component (B) contains a water-soluble soap, which significantly improves the washing-in behavior in the washing machine.
- the soap-containing additive has a lower absorbency for nonionic surfactants and has a lower self-ignition temperature or an increased flammability.
- the object of the invention was to provide an additive for granular and phosphate-free detergents and cleaning agents which contains nonionic surfactants and which has both improved wash-in behavior and an increased autoignition temperature or a reduced flammability.

- Both components can have the same or a different grain size within the specified limits. Mixing and treating them together with nonionic surfactants can result in a slight agglomeration of the particles, in particular by attaching finely divided components to larger grains, and thus overall a slight increase in the average grain size.
- the proportion of sodium perborate monohydrate (component A) is preferably 20 to 60% by weight and in particular 30 to 50% by weight.
- the proportion of component (B) is preferably 35 to 70% by weight and in particular 40 to 60% by weight.

- the perborate monohydrate is preferably used as a loose, expanded granulate with a liter weight of 450 to 650 g / 1, preferably 500 to 600 g / 1.
- Granules of this type are notable for good adsorption capacity for liquid to lard-like nonionic surfactants. Loading the granules with the nonionic surfactants generally increases the bulk density by about 50 to 200 g / l, which is in the interest of a higher total bulk weight and a saving in packaging and transport volume.
- Component (B) likewise preferably consists of a granular, porous material, as can be obtained by spray drying aqueous slurries of water-insoluble or water-soluble salts or salt mixtures. It contains synthetic zeolite of the NaA type in proportions of 45 to 75, preferably 50 to 72% by weight and in particular 55 to 70% by weight (based on anhydrous substance). Mixtures of zeolite NaA and NaX can also be used, the proportion of the zeolite NaX in such mixtures advantageously being below 30%, in particular below 20%. Suitable zeolites have no particles larger than 30 ⁇ m and consist of at least 80% particles less than 10 microns in size.
- Their average particle size (volume distribution, measurement method: Coulter Counter) is in the range of 1 to 10 ⁇ m.
- Their calcium binding capacity, which is determined according to DE 24 12837, is in the range from 100 to 200 mg CaO / g.

- Another advantageous component of component (B) is sodium sulfate, which is calculated as an anhydrous substance and is present in proportions of 0 to 30% by weight, preferably 1 to 25 and in particular 3 to 20% by weight.
- the sodium sulfate contributes to a considerable improvement in the grain structure of component (B) and the washing-in behavior of the detergent additive and at the same time increases its bulk density, which results in the possibility of saving packaging and transport volume.
- Another inorganic salt that can be combined with the zeolite is sodium carbonate, which can be present in proportions of up to 20% by weight, based on component (B). With regard to the flushing-in behavior, however, such mixtures are inferior to the mixtures of zeolite and sodium sulfate.

- the proportion thereof, in the interest of sufficient water solubility is not more than 50 mole percent, preferably less than 30 mole percent.
- Copolymers of acrylic acid or methacrylic acid with maleic acid as described in more detail in EP 25551, for example, have proven particularly suitable. These are copolymers which contain 40 to 90% by weight of acrylic acid or methacrylic acid and 60 to 10% by weight of maleic acid. Such copolymers are particularly preferred, in which 45 to 85 percent by weight acrylic acid and 55 to 15 percent by weight maleic acid are present.
- the molecular weight of the homopolymers or copolymers is generally 2,000 to 150,000, preferably 5,000 to 100,000.
- Their proportion in component (B) is, for example, 1 to 12% by weight, preferably 1.5 to 8% by weight. and in particular 2 to 5% by weight, calculated as the sodium salt.
- the resistance of the grains to abrasion increases with an increasing proportion of polyacid or its salts. With a proportion from 1.5% by weight, sufficient abrasion resistance is achieved in many cases. Mixtures with 2 to 5% by weight of sodium salt of polyacid have optimal abrasion properties.
- the zeolite in those cases in which the zeolite is used in the production of the granular component (B) not in powder or spray-dried form, but rather as a moist filter cake, it can contain dispersion stabilizers, as described in more detail in DE 2527388 .
- Suitable stabilizers are in particular nonionic surfactants with HLB values below 12, such as ethoxylated tallow alcohol with 3 to 8 E0.
- the proportion of these additives in the powder component (B) can, depending on the zeolite content, be up to 4% by weight, usually 0.3 to 3% by weight. In the final balance, this proportion of component (C) is added.
- the difference of up to 100% by weight is due to water, which is present in bound form and as moisture, the main amount being bound to the zeolite.
- a proportion of the water which is about 8 to 18 wt .-% (based on the agent) can be removed at a drying temperature of 145 ° C.
- Another portion which is between 4 and 8% by weight depending on the zeolite portion, is released at the annealing temperature by about 800 ° C. and corresponds to the water stored in the crystal lattice of the zeolite.

- the bulk density of component (B) in the preferred embodiment is 400 to 680 g / 1, preferably 450 to 650 g / 1. The adsorption of the nonionic surfactants also increases it by 50 to 200 g / l.
- the nonionic surfactants adsorbed on the mixture of components (A) and (B) are those which are usually used in washing and cleaning agents.
- Other suitable additives are organic solvents with which the cleaning ability of detergents and cleaning agents is improved, in particular with regard to greasy soiling, and which can be incorporated into a granular cleaning agent without problems in this way.
- other substances such as fragrances, finishing agents, optical brighteners and anionic or cationic surfactants, can also be mixed into the mixture of components (A) and (B) after prior dissolution or dispersion in organic solvents or the liquid or melted nonionic surfactants . These substances penetrate into the porous grains together with the solvent or dispersant and are thus protected against interactions with other powder components.
- Preferred detergent constituents which are bound to the granular mixture and are present together with this as a free-flowing mixture are liquid to pasty nonionic surfactants from the class of the polyglycol ethers, derived from alcohols with 10 to 22, in particular 12 to 18, carbon atoms.

- the bulk density of the additives according to the invention is preferably between 600 and 950 g / 1, in particular between 650 and 850 g / 1.
- the advantages of the additives according to the invention lie above all in that they have an increased autoignition temperature or a lower flammability with comparable flushing behavior compared to soap-containing additives of the prior art.
- additives of the prior art which contain zeolite and (co) polymeric polycarboxylates, but neither soap nor layered silicates, depending on the amount of nonionic surfactant applied, they have an analog to better auto-ignition temperature or flammability and better flushing behavior.
- An additional advantage of these additives is that they are more free-flowing than the additives of the prior art mentioned.
- the preparation of component (B) in the preferred embodiment is based, for example, on an aqueous batch containing a total of 40 to 55% by weight of water-free ingredients, which is sprayed into a drop space by means of nozzles and by means of drying gases, which have an inlet temperature of 150 to 280 ° C and an outlet temperature of 50 to 120 ° C, is dried to a removable moisture content at 145 ° C.

- the spray drying is conducted in such a way that the particle size of the spray product has the distribution indicated above.
- Existing fine and coarse grains are screened before further processing. It has been shown that the rinsing behavior of the adsorbent impregnated with nonionic surfactants deteriorates with increasing proportion of fine grain.
- Both powder components are combined into a homogeneous mixture and then mixed with liquid or non-ionized liquid that is liquefied by heating. African surfactants or tensidge is treated.
- the nonionic surfactant is expediently sprayed onto the agitated mixture. Heating the nonionic surfactant to temperatures between 35 and 60 ° C, preferably 40 to 50 ° C, accelerates the adsorption process.
- the abrasion resistance and constancy of shape of the grains is so high if the specified proportions or production conditions are observed that the freshly prepared, but especially the cooled and, if necessary, reheated, matured grains treated with the liquid additives are treated under the usual spray mixing conditions and can be promoted without the formation of fine particles or coarser agglomerates.

- the mixing and spraying process can also be carried out in a single mixing apparatus in the case of continuous operation, the two powder components being combined in a first mixing section and the nonionic component being added in a final mixing section.
- a particular advantage of the invention is that the adsorption of the liquid nonionic surfactants and their diffusion into the interior of the grain takes place comparatively quickly. Shortly after leaving the mixing apparatus, the grain mixtures have their full flowability and can be processed further without intermediate storage or time-consuming post-ripening process.
- Suitable powdering agents have a grain size of 0.001 to at most 0.1 mm, preferably less than 0.05 mm and can be present in proportions of 0.03 to 3, preferably 0.05 to 2% by weight, based on that adsorbents loaded with additive are used.
- finely powdered zeolites for example, finely powdered zeolites, silica airgel (aero- sil ( R )), colorless or colored pigments, such as titanium dioxide and other powder materials already proposed for powdering granules or detergent particles, such as finely powdered sodium tripolyphosphate, sodium sulfate, magnesium silicate and carboxylmethyl cellulose.
- colorless or colored pigments such as titanium dioxide
- other powder materials already proposed for powdering granules or detergent particles such as finely powdered sodium tripolyphosphate, sodium sulfate, magnesium silicate and carboxylmethyl cellulose.

- granular detergents or detergent components such as are obtainable for example by spray drying or granulation
- bleaches or are mixed with bleach-containing detergents of known composition in any ratio are of great advantage, since an undesired formation of abrasion and dust is avoided.
- the powder mixtures are in turn stable in storage and do not tend to clump or exude the non-ionic surfactant. When used, they are particularly easy to flush in compared to known agents.
- the admixed spray powders and granules can also contain sodium sulfate, which is often advantageous for their grain properties, in particular in the absence of phosphates. These admixed detergent components are therefore preferably also phosphate-free.
- the absorption capacity of the granulate mixture according to the invention for non-ionic surfactants is so high that there is no need to apply these tenides to other mixture components.

- the additives AI, VI and V2 each contained 34.1% by weight of component (B); additives A2, V3 and V4 each contained 46.5% by weight of component (B).
- the mixtures of perborate monohydrate and component (B) were each sprayed with 25% by weight, based on the sprayed additive, of C ⁇ 2-C ⁇ 8 fatty alcohol with 5 EO; in the additives A2, V3 and V4, the mixtures of perborate monohydrate and component (B) were each with 12.6% by weight, based on the sprayed additive, Ci2-C]. 8 fatty alcohol sprayed with 5 E0.

On y est parvenu grâce à un additif granulaire et sans phosphate, qui comporte: (A) 10 à 70 % en poids de monohydrate de perborate de sodium ayant une grosseur granulaire moyenne comprise entre 0,2 à 1,2 mm, (B) 25 à 80 % en poids d'un mélange granulaire ayant une grosseur granulaire moyenne comprise entre 0,2 et 1,2 mm, qui est au moins à 75 % en poids de nature inorganique et dépourvu de peroxygène et (rapporté à la substance anhydre dans le constituant B) contient 45 à 75 % en poids de zéolithe synthétique en fins cristaux , 0 à 30 % en poids de sulfate de sodium et 1 à 12 % en poids de sels d'acides carboxyliques homopolymères ou copolymères, (C) 5 à 30 % en poids de tensioactifs non ioniques qui sont liés aux constituants granulaires (A) et (B), (B) comportant 2 à 10 % en poids, rapporté à la substance anhydre dans le constituant (B), d'un silicate stratifié.
