Sulfosuccinates and Sulfosuccinamates are members of a large group of cosmetic chemicals best represented as the salts of substituted sulfosuccinic acids:
Regardless of substitution, the sulfonic acid group is always ionized, and M+ represents the counterion. In compounds in which X or Y represents an alkyl or substituted alkyl group, the remaining carboxyl function is also present in salt form, (e.g., Disodium Deceth-6 Sulfosuccinate). If both X and Y represent alkyl or substituted alkyl groupings, the sulfosuccinate is a diester, (e.g., Dioctyl Sodium Sulfosuccinate). Fairly complex multifunctional substituents can be present on the carboxyl groups of this category. Alternately, the XO or the YO groups may be replaced by a substituted N-atom, in which case the resulting sulfosuccinamate is a monoamide (e.g., Disodium Stearyl Sulfosuccinamate).
Sulfosuccinates and Sulfosuccinamates are used in cosmetics as emulsifiers and wetting agents. Depending on the type of substituents carried by these molecules, they may also function as (substantive) skin and hair conditioners. Others exhibit characteristics which make them useful in diverse specialty applications. |
