Abstract
An aqueous liquid laundry detergent composition comprising an alkoxylated carboxylic acid surfcatant and a free radical scavenger in the mole ratio of from about 500:1 to about 20:1. The composition substantially prevents the degradation of the alkoxylated ester surfactant upon storage and is also color-stable.
