Science
Mechanism of Action
This ingredient operates as an amphoteric surfactant, meaning it possesses both acidic and basic properties, allowing it to interact effectively with various substances. On the skin, its primary mechanism involves breaking surface tension and enabling water to intermix with hydrophobic oil and dirt particles. This emulsifying action allows these impurities to be easily rinsed away. Beyond cleansing, it contributes to product aesthetics and performance by boosting foam, providing antistatic effects, and acting as a hydrotrope to enhance the solubility of other compounds.

Safety Profile
While a direct, standalone CIR safety assessment for Disodium Stearoamphodiacetate is not available, the CIR Expert Panel has evaluated structurally similar fatty amphocarboxylates, such as Disodium Cocoamphodiacetate and Disodium Lauroamphodiacetate, and deemed them safe for cosmetic use within current industry practices and concentrations. The FDA UNII for this ingredient is 8N9P6X9C6N. Specific SCCS opinions were not identified.

Verdict
While effective as a cleansing and foam-boosting amphoteric surfactant, a definitive Moumoujus rating is currently precluded by the insufficient direct clinical and safety data for Disodium Stearoamphodiacetate itself.
