Binder-anionic synthetic surfactant paste or water-soluble polymer containing at least 50 wt.% of ethylene oxide, and preferably may contain a small amount of ethoxylated non-ionic surfactants. The agglomerates also essentially free from amorphous alkali metal silicates, if free water is present. S.p. f-crystals, 3 tables.

The invention relates to a method of agglomeration of crystalline aluminosilicate and/or layered silicate detergent components (additives) by mixing such materials with selected binders in high-performance mixer, such as mixer Erich.

The method leads to the formation of free flowing agglomeration having good dispersibility in water. The agglomerates are used as detergent additives, especially in the granular compositions for washing used in laundries.

The aluminosilicates also interact with carbonates and amorphous silicates, are typically present in the mixer for vertical mixing, which leads to the formation of granules with aggravated exchange capacity of calcium ion and solubility, respectively.

The agglomerates or particles containing aluminosilicate additive, also described in this field. For example, U.S. patent 4528276, Cambell et al., publ. July 9, 1985, discloses the agglomerates formed by the mixing of hydrated silicates of the alkali metal zeolites during heating and humidification.

U.S. patent 4096081, Phenicie et al., publ. June 20, 1978, discloses detergents containing solid particles of a mixture of aluminosilicate, salt and agglomerated agent, including polymers containing basic units of ethylene oxide. Particles are usually obtained by spray drying or cooling Publ. November 8, 1983, discloses agglomerates of zeolite (preferably amorphous), obtained using a water-soluble binder. Example 8 discloses the sinter obtained by mixing 50 PM amorphous zeolite and 50 sludge line Las (60% activity). It is noticed that when instead of amorphous zeolite used crystalline zeolite A, the resulting products pasty and will never be satisfactorily fluid."

In [1] revealed granular detergents containing 17 - 35% of surface-active substances (surfactants), at least part of which is anionic, and 28 - 45% of zeolite (anhydrous basis). The composition is prepared by granulation and compaction in high-speed mixer-granulator in the presence of a binder, preferably water. In examples 11 and 12 powder prepared by dry mixing line Las, non-ionic surface-active zeolite and other ingredients, seal and granularit after adding 1% of water as a binder.

In [2] in example 7 revealed "free-flowing granules obtained by granulating 12% non-ionic surfactant, 20% suspension (31% activity), surfactant-sulfonyloxy ester of fatty acid and 68% of zeolite.

Anionic surfactants are used here in the form of paste or concentrated mixtures with water. These anionic pastes contain 0 to 90% water, preferably from 2 to 75% water, and most preferably 4 to 60 wt.% water.

Such high viscosity binders are distributed more evenly on the surface of the crystalline additives Trast wax-like binder, which easily forms larger particles of the desired size in the mixer. The waxy binder system is not strong enough to keep the size of the particles larger than described here. This prevents the super-agglomeration and leads to the formation of uniform particles having a narrow size distribution.

Used anionic surfactants include water-soluble salts, preferably the alkali metal, ammonium and alkylammonium salts, products of organic sulfuric acid reaction, having in its molecular structure an alkyl group containing 10 to 20 carbon atoms and the ether group, a sulfuric acid or sulfonic acids.

Anionic surfactant paste can also contain minor amounts of ethoxylated nonionic surfactants. In such cases, the weight ratio of anionic surfactant to ethoxylated nonionic surfactant should be at least 3:1, preferably at least 4:1, more preferably at least 5:1.

Such nonionic what Kim hydrophobic compound, which can be, by their nature, aliphatic or alkylaromatic. Length polyoxyethylene group which condenses with a particular hydrophobic group can be readily adjusted to obtain a water soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.

Suitable nonionic surfactants include polietilenoksidnoy condensates of alkyl phenols, for example, condensation products alkylphenol having alkyl group containing 6 to 15, preferably 8 to 13 atoms of carbon, or straight or branched chains with ethylene oxide in an amount of 3 to 20, preferably 4 to 14, more preferably 4 to 8 mol per 1 mol of alkylphenol.

Preferred nonionic surfactants are water - soluble and water-dispersible condensation products of aliphatic alcohols or carboxylic acids having 8 to 22 carbon atoms, straight or branched chain, with ethylene oxide in an amount of 3 to 20, preferably 3 to 60 mol per 1 mol of the alcohol or acid.

Such polymers (or their mixtures) typically have a melting point not less than 35oC. Preferably, the polymeric material will have a melting point of at least 45oC, more preferably not less than 50oC and most preferably at least 55oC. Since the polymer materials used in the practice of the invention, usually a mixture of representing the area of molecular weights, materials tend to soften and become liquid in the temperature range 3 - 7oC above their melting points.

The polymeric binder may also contain ethoxylated nonionic surfactants described above, providing the weight ratio of polymer to ethoxylated nonionic surfactant of at least 1:1. Preferably this ratio is at least 2:1, more preferably at least 3:1. Such a mixture of a polymeric binder and a nonionic surfactant may also contain water without adverse effect on the agglomerates. However, a polymeric binder without ethoxylated pianosolo preferred binder system contains a mixture of polyethylene glycol, with an average mol. m 3000 - 10000 with ethoxylated nonionic surfactant which is the condensation product of C9-C16alcohols with ethylene oxide in amounts of 4 to 8 mol per 1 mol of alcohol. Such mixtures result in improved cleaning ability compared to other used binder systems. System linking polyethylene glycol/nonionic surfactant lose crystalline additive faster than other binders. This allows incremental material to start faster to carry out its functions in to the washing solution, to quickly and effectively reduce the hardness of water, one hundred and leads to improved cleaning ability.

In addition to the above, the amount of crystalline detergent additives to the binder should be selected so that the weight ratio of such additives to the binder is made from 1075:1 to 3.5:1, preferably from 1.9:1 to 3:1.

Moreover, to reduce the interaction between crystalline additive and amorphous alkali metal silicates, which may endanger the solubility product, the agglomerates of the invention are essentially free from amorphous alkali metal silicates commonly used in granular detergent substances remaining water.

The agglomerates of the invention may also contain minor amounts (e.g. up to 30 wt.%) other ingredients which do not reduce significantly the characteristics and physical properties. For example, the agglomerates may contain inorganic salts such as disclosed in the aforementioned U.S. patent 4096081, Phenicil eb cll, particularly from column 14,line 53 to column 15, line 8, to which reference is made. Such salts reduce the amount of binder required to obtain qualitative agglomerates according to the invention. Hydrotropes, such as toluene, xylene and kumulantami, can also be used to provide similar effects.

The agglomerates may also contain other surfactants or ingredients, including ingredients that are sensitive to heat or decomposed materials in a vertical mixer for mixing the slurry, which is subjected to spray drying to obtain equilibrium in the final detergent substance.
