C11-13 PARETH-6 — Moumoujus

C11-13 PARETH-6.

Valuable CAS - / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic surfactant that excels at creating stable emulsions between oil and water phases while providing gentle cleansing properties. This ethoxylated alcohol derivative reduces surface tension to facilitate product spreadability and helps remove impurities without stripping the skin barrier.

Science

Mechanism of Action

Functions by lowering surface tension between oil and water phases to form stable emulsions, while its molecular structure allows formation of micelles that encapsulate dirt, oil, and debris for effective removal during cleansing.
