COMPOSITION OF AMORPHOUS ALKALI METALS SILICATE PREPARED BY SPRAY DRYING HAVING SECONDARY DETERGENT POWER, DETERGENT AND EXTRUDED DETERGENT COMPRISING SAID COMPOSITION Russian patent published in 2001 - IPC

FIELD: chemical industry. SUBSTANCE: described is composition of amorphous alkali metal silicate prepared by spray drying, having secondary detergent power and comprising anionic surfactants and water, ratios of components being as follows, wt: amorphous alkali metal silicate, 15-80; anionic surfactants, 0.5-mmore than 30; and water, the balance. M₂O to SiO₂ molar ratio is silicate varies form 1:1.5 to 1:3.3 (M is alkali metal), and composition is treated with liquid components which are essentially detergent components, more particularly nonionic surfactants. Said composition is component of (a) detergent containing 0-5 or 10-16 wt % of zeolite calculated for anhydrous active ingredient or (b) extruded detergent with bulk weight of more than 600 g/l comprising anionic and optionally nonionic surfactants. Said composition makes it possible to widen range of agents having highly efficient detergent power. EFFECT: improved properties of the composition. 10 cl, 4 ex, 1tbl
