ABSTRACT:
A phosphate-free granular laundry detergent having a cleaning performance comparable to that of a premium phosphate-containing laundry detergent has a surfactant content of 1-30% and a detergent builder content of at least 50% by weight and contains:
(A) as its sole surfactant, a mixture of 20-98% by weight of an ethoxylated fatty alcohol corresponding to the formula Z(OCH.sub.2 CH.sub.2).sub.n OH in which Z is an alkyl group containing 8-30 carbons and n is an integer of 1-50, 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 and
(B) as its sole detergent builder, a mixture of a sodium aluminum silicate, an anti-redeposition agent, sodium silicate, and at least one different water-soluble inorganic salt in proportions such that the laundry detergent contains 1-50% by weight of the sodium aluminum silicate, 0.1-5% by weight of the anti-redeposition agent, 1-20% by weight of the sodium silicate, and 10-80% by weight of the different inorganic salt.
