AMMONIUM DIMETHICONE PEG-7 SULFATE.

Valuable / SKIN CONDITIONING

A hybrid silicone-surfactant that combines the conditioning benefits of dimethicone with gentle cleansing properties. This water-soluble ingredient reduces the harshness of traditional surfactants while providing slip and foam stability in cleansing formulations.

Summary

surfactant cleansing skin conditioning foam stabilizer

Science

Mechanism of Action

Functions as an anionic silicone surfactant by utilizing its dimethicone backbone for conditioning and surface tension reduction, while the sulfated PEG-7 group provides water compatibility and complexes with other surfactants to minimize irritation potential.
