SODIUM METHYL OLEOYL TAURATE.

Valuable CAS 137-20-2 / 7308-16-9 / ANTISTATIC, CLEANSING, FOAMING, SURFACTANT - CLEANSING

Sodium Methyl Oleoyl Taurate is a gentle anionic surfactant derived from oleic acid and taurine, designed for effective yet balanced cleansing without over-stripping the skin's natural lipids. It is highly valued for its low irritation potential and its ability to contribute to a rich, stable foam in formulations.

Summary

antistatic cleansing foaming surfactant emulsifier

Science

Mechanism of Action

Functioning as a mild anionic surfactant, Sodium Methyl Oleoyl Taurate significantly reduces surface tension, enabling it to efficiently emulsify and break down oil, dirt, and other impurities on the skin and hair, allowing them to be rinsed away. This mechanism provides thorough cleansing while helping to preserve the skin's natural moisture barrier. Furthermore, it enhances foam quality and stability, and can act as an emulsion stabilizer in skincare formulations.
