Mechanism of Action
This ingredient functions as a disodium salt of a tridecyl alcohol half ester of sulfosuccinic acid. Its primary action as a surfactant is to significantly lower the surface tension between disparate substances, such as oil and water. This allows for efficient emulsification and dispersion, facilitating the removal of impurities and contributing to effective cleansing. Additionally, it boosts the stability and volume of foam and acts as a hydrotrope, thereby increasing the aqueous solubility of poorly soluble compounds.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Disodium Tridecylsulfosuccinate and related dialkyl sulfosuccinate salts are safe for cosmetic use, provided they are formulated to be non-irritating. The panel indicated a potential for ocular and skin irritation if not properly formulated, with safety data for this group often extrapolated from diethylhexyl sodium sulfosuccinate.
