Abstract (en)
[origin: WO9312217A1] A phosphate-free granular laundry detergent having a cleaning performance comparable to that of a premium phosphate-containing laundry detergent comprises: (A) 1-30 % by weight of a surfactant, (B) 1-50 % by weight of a sodium aluminum silicate detergent builder, (C) 1-20 % by weight of sodium silicate, (D) 0.1-5 % by weight of an anti-redeposition agent, and (E) 10-80 % by weight of inorganic filler, the surfactant consisting of: (1) a mixture of 20-98 % by weight of an ethoxylated fatty alcohol, 1-75 % by weight of an alkali metal or ammonium salt of an alkylbenzene sulfonate in which the alkyl group contains 10-18 carbons, and 1-20 % by weight of an amine oxide corresponding to the formula RR'R''NO in which R is a primary alkyl group containing 8-24 carbons; R' is methyl, ethyl, or 2-hydroxyethyl; and R'' is independently selected from methyl, ethyl, 2-hydroxyethyl, and primary alkyl groups containing 8-24 carbons, or (2) a mixture of 85-98 % by weight of the ethoxylate, 1-12 % by weight of a fatty acid soap, and 1-6 % by weight of the amine oxide.
