RAPIDLY WATER-SOLUBLE SOLID DETERGENT COMPOSITION WITH LOW DENSITY AND LOW CONTENT OF BASIC DETERGENT COMPONENT Russian patent published in 2011 - IPC C11D11/02 

FIELD: chemistry.

SUBSTANCE: solid detergent composition has packed density of 100-500 g/l and contains: an anionic surface-active agent, a zeolite basic detergent component, a phosphate basic detergent component and other detergent ingredients. The composition contains 61-90 wt % powdered component of low density between 100 g/l and 426 g/l, and 10-39 wt % powdered component of high density of 426-5000 g/l. The powdered components contain inorganic and organic substances. The ratio (i) of the weight ratio of the inorganic substance to the organic substance contained in the powdered component (I) of low density to (ii) the weight ratio of the inorganic substance to the organic substance contained in the solid detergent lies between 0.3:1 and 5:1.

EFFECT: invention enables to obtain a solid detergent which, in a wide range of common dosages, dissolves well in water and provides an excellent washing effect, especially removing stains and preserving whiteness.
