ABSTRACT:
The divalent ion sequestration rate of a zeolite is increased by blending it with an amine oxide corresponding to the formula RR'R"NO in which R is a primary alkyl group containing 6-24 carbons and R' and R" are independently selected from methyl, ethyl, and 2-hydroxyethyl to provide about 2.3-7.0 mmols of amine oxide per gram of zeolite. Preferred ingredients are zeolite A and N-tetradecyldimethylamine oxide, and the increased sequestration rate makes the zeolite more suitable for use as detergent builder in anionic surfactant-containing cleaning compositions.
