Science
Mechanism of Action
This ingredient operates by significantly lowering the surface tension of liquids and the interfacial tension between oil and water phases. Its molecular architecture includes both lipophilic and hydrophilic segments, enabling it to bridge these disparate phases. This dual functionality is crucial for forming stable emulsions, facilitating efficient cleansing by lifting impurities, and ensuring the uniform dispersion of oils and active ingredients within a formula. It also plays a role in generating and stabilizing foam.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that a broader group of 28 alkyl phosphates, chemically similar to this ingredient, are considered safe for use in cosmetics under current practices and concentrations, provided formulations are non-irritating. There is a recognized likelihood of irritation, with the risk potentially increasing when combined with other known problematic ingredients. No specific SCCS assessment or FDA regulation for this exact ingredient has been found.
