Science
Mechanism of Action
Operating as a surfactant, Disodium Stearyl Sulfosuccinamate reduces the surface tension between ingredients, facilitating the removal of impurities and oils from the skin. Its foam-boosting capability significantly improves the volume, texture, and stability of lather. Furthermore, it acts as a hydrotrope, increasing the aqueous solubility of other components, thereby optimizing formula stability and performance.

Stability
This ingredient is readily soluble in water and maintains stability across weak acid, weak alkali, and hard water conditions. However, it is prone to hydrolysis under strong acid or strong alkali environments, making it most suitable for neutral formula systems.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not formally concluded on the safety of Disodium Stearyl Sulfosuccinamate as a specific monoester. While other alkyl sulfosuccinate salts (diesters) have been evaluated, the Panel determined that their safety data could not be directly 'read-across' to address the safety profile of polar monoesters like this compound, indicating a specific lack of comprehensive review.

Verdict
While Disodium Stearyl Sulfosuccinamate offers effective cleansing and foam-boosting properties suitable for diverse skin types, a definitive safety conclusion by the CIR and specific irritancy/comedogenicity data for this monoester are currently unavailable.
