Abstract
Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of sulfosuccinic acid or a salt of sulfosuccinic acid present in an amount of at least about 4% based on the weight of the sulfosuccinate surfactant.
