Science
Mechanism of Action
This compound functions by significantly lowering the surface tension of aqueous solutions, which improves their ability to wet surfaces and disperse immiscible phases. In cleansing applications, it aids in the breakdown and removal of lipid-based impurities by enabling the 'rolling up' and lifting of oily soils, followed by their solubilization and the formation of stable emulsions. However, as a strong surfactant, it is known to interact with the stratum corneum by binding to cellular membranes, potentially leading to membrane swelling and subsequent skin irritation.

Safety
Safety Profile
There is no specific Cosmetic Ingredient Review (CIR) safety assessment available for Sodium Hexyldiphenyl Ether Sulfonate. General chemical hazard classifications identify it as an irritant (Xi), particularly noting its capacity to cause serious eye irritation (H319). Its interaction with the stratum corneum, as part of its mechanism, is linked to potential skin irritation. The ingredient is also classified as dangerous for the environment, being toxic to aquatic life with long-lasting effects (H411).
