Known composition of amorphous alkali metal silicate, obtained by spray drying with the secondary washing ability, containing anionic surfactant, water and optionally, an additional alkaline carbonate, with the molar ratio of M2O (M alkali metal) and SiO2is 1: (2,5-3,6) (see application DE N 2730951, CL C 11 D 17/06, 12.1.1978).

The objective of the invention is to expand the range of products, with high performance secondary washing ability.

The problem is solved by the proposed composition of the amorphous alkali metal silicate, obtained by spray drying with the secondary washing ability, containing anionic surfactant and water, due to the fact that the components of the composition are taken in the following ratio (% wt.):

amorphous alkali metal silicate - 15-80

anionic surface-actional metal) and SiO2in the silicate is 1:1.5 to 1:3.3, then the composition of the treated liquid components representing components of detergents or detergents, in particular nonionic surfactants.

The composition may further comprise about 30 to 70 wt.%, preferably 40 to 65 wt.% carbonate of an alkali metal.

The preferred composition of amorphous alkali metal silicate contains M2O and SiO2in a molar ratio of 1:1.9 to 1:3, in particular 1:2,5. In particular, the use of sodium silicate and/or potassium. For reasons of economy prefer silicates of sodium. However, if for reasons of application is desirable especially a high rate of dissolution in water, it is recommended that at least partially replace sodium with potassium. For example, the composition of the silicate of an alkali metal can be selected by software in its potassium content, calculated on the K2On leaving up to 5 wt.%. Preferably the alkali metal silicates are mixed with carbonate of an alkali metal, preferably sodium carbonate and/or potassium. The water content in these preferred compositions of amorphous alkali metal silicate preferably predpochtitelney.

The proposed composition obtained by spray drying aqueous suspensions containing silicates of the alkali metal and anionic surfactants, resulting in gain, in particular, compounds of alkali metal silicate having a water content of 14 to 19 wt.%. In particular, for sprinkling take aqueous suspension, optionally containing alkali metal carbonates, preferably sodium carbonate and/or potassium. Spray drying can also be carried out with the use of superheated steam. Thus obtained composition of amorphous alkali metal silicate liquid components representing components of detergents or detergents. This processing can be performed by conventional methods, for example, by mixing or spraying in a mixing apparatus or the apparatus for granulating, if necessary, additional heat treatment.

As the anionic surfactants used in the composition of the amorphous alkali metal silicate, especially suitable surfactants of the sulfonate type and/or sulfate. Among the surfactants of the sulfonate type preference is unsulfonated, oxyalkylene and disulfonates obtained, for example, by sulfating monoolefins from 12 to 18 carbon atoms with terminal or internal double bond by using gaseous sulfur trioxide, with subsequent alkaline or acidic hydrolysis products sulfating. Suitable are also alkanesulfonyl derived from alkanes with 12-18 carbon atoms, for example, by sulfochloride or sulfoximine with subsequent hydrolysis or neutralization. Suitable surfactants of the sulfate type are difficult monetary sulfuric acids from primary alcohols of natural and synthetic origin. As ALK(EN)insulaton prefer salt of an alkali metal, in particular sodium salts of complex profirov sulfuric acid of fatty alcohols with 12 to 18 carbon atoms, for example, alcohol, coconut oil, alcohol, fat, lauric, miristinovoi, cetyl or starlogo alcohol, or oxaspiro with 10-20 carbon atoms, and complex palefire secondary alcohols with the same chain length. Further preferred are ALK(EN)insulate specified chain length containing synthetic, obtained on a petrochemical basis, unbranched alkyl CSO raw materials. From the point of view of the washing process are of special interest ALK(EN)insulate with 16-18 carbon atoms. This may be particularly advantageous, in particular, in the case of detergents for washing machines, to use ALK(EN)inculpate in combination with low-melting anionic surfactants, in particular, such surface-active substances, which have a low point Krafft and at a relatively low temperature washing, for example, room temperature or temperatures up to 40oC, with little tendency to the formation of crystals. Therefore, according to the preferred form of execution of the invention the composition contains a mixture of alkyl sulphates of fatty acids with short and long chain, preferably a mixture of alkyl sulphates of fatty acids with 12 to 14 carbon atoms or from 12 to 18 carbon atoms with alkyl sulphates of fatty alcohols with 16 to 18 carbon atoms, in particular alkyl sulphates of fatty alcohols with 12 to 16 carbon atoms with alkyl sulphates of fatty alcohols with 16 to 18 carbon atoms.
