DEA-C8-18 PERFLUOROALKYLETHYL PHOSPHATE.

Avoid CAS 223239-91-6 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

DEA-C8-18 PERFLUOROALKYLETHYL PHOSPHATE is a per- and polyfluorinated alkyl substance (PFAS) primarily functioning as a surfactant and emulsion stabilizing agent. While it aids in product formulation, its use is significantly restricted due to substantial health and environmental concerns.

Summary

Surfactant Emulsion Stabilizer Solvent

Science

Mechanism of Action

This ingredient reduces the surface tension of liquids, facilitating the mixing of immiscible substances like oil and water. It thereby functions as a surfactant, assisting in cleansing and foam production, and acts as an emulsion stabilizer to maintain product homogeneity and prevent separation.
