AQUEOUS DETERGENT COMPOSITION FOR SOLID SURFACES AND METHOD FOR IMPROVING QUALITY OF SOLUTION Russian patent published in 1998 - IPC

FIELD: detergents. SUBSTANCE: composition contains 3 to 35 wt % of a surfactant system. The latter includes at least 20% (based on total surfactant weight) of C₁₀-C₁₆-alkylethoxy sulfate with average number of ethylene oxide 1-10 per 1 molecule and other anionic surfactants, C₅-C₂₀- alkyldiethanolamide, and C₈-C₁₆-alkylamine oxide. Composition also contains 0.01-0.5% of calcium ions and functional additives (to 100%). Content of alkylethoxy sulfate in composition is at least 3 wt %. According to invention, calcium ions are added in the form of water-soluble calcium salt. EFFECT: improved touch quality of composition solution, got over deterioration of solution on storage, and improved its detergent ability. 11 cl, 1 tbl
