AMMONIUM C9-10 PERFLUOROALKYLSULFONATE.

Avoid / CLEANSING, SURFACTANT - CLEANSING

Ammonium C9-10 Perfluoroalkylsulfonate is an anionic fluorinated surfactant. It is primarily valued for its surface tension-lowering properties rather than direct skin benefits.

surfactant cleansing

Science

This ingredient significantly reduces the surface tension of aqueous solutions, functioning as a cleansing agent and emulsifier. Its robust perfluorinated chain provides high chemical and thermal stability, aiding even product distribution and foam stability.
