Science
Mechanism of Action
This ingredient operates by reducing the surface tension between different phases within a formulation, acting as an effective surfactant. Its emulsifying properties enable the stable blending of immiscible liquids, while its dispersant capabilities ensure inorganic particles, such as mineral UV filters or pigments, are evenly distributed. This action prevents clumping, enhancing overall product stability and consistent delivery of active components.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of a broader group of alkyl phosphates, concluding they are safe for use in current practices and concentrations when formulated to be non-irritating. The panel did highlight a potential for ocular irritation if applied neat or as granular substances, advising manufacturers to consider this for products used near the eye.
