Abstract: The gelling temperature of liquid nonionic detergents is lowered by 2.degree. C. or more by the addition of aliphatic linear or aliphatic monocyclic dicarboxylic acids such as the C.sub.6 to C.sub.12 alkyl and alkenyl derivatives of succinic acid or maleic acid and the corresponding anhydrides. Non-aqueous heavy duty built liquid laundry detergent compositions which do not gel when added to water at a temperature near freezing are disclosed.
