ABSTRACT:
A clear liquid synthetic organic heavy duty laundry detergent composition includes a condensation product of a higher fatty alcohol and polymeric ethylene oxide, fluorescent brightener, water and lower monohydric alcohol. The liquid detergent composition is biodegradable. The substantial proportion of nonionic condensation product detergent present is prevented from gelling by the alcohol and in turn, aids in solubilizing the fluorescent brightener. In preferred compositions, small proportions of sequestering agents e.g., nitrilotriacetate, and salt-forming base, e.g., monoethanolamine, are also present. Surprisingly, cleaning of soiled laundry is comparable to that obtained with the equivalent quantities of phosphate-containing built detergents, even when the present liquid contains much less than a normal building proportion of nitrilotriacetate or other substitute for the phosphate.
