WASHING COMPOSITIONS

摘要

A washing composition comprising (a) a detergent material; (b) a fragrant aldehyde; (c) a polyethylene imine of the general formula -(CH2CH2NH)n-; and (d) an aromatic, monoethylenically-unsaturated carboxylic acid ester of the formula (I) where R<1> is selected from the group consisting of hydrogen, C1-C16 alkyl, C1-C16 alkoxy, aryl and substituted aryl, and R<2> is selected from the group consisting of aryl, substituted aryl and C6-C16 alkyl; the materials (b)-(d) each having an odour value of 10,000 maximum. The problem of rancidity, commonly encountered when low-grade detergent materials are used, especially in laundry soaps, is considerably reduced.
