C12-14 SEC-PARETH-7.

Valuable / EMULSION STABILISING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic surfactant and emulsifier featuring a secondary alcohol structure that provides superior wetting properties and enhanced product spreadability. Its dual hydrophobic-hydrophilic chain system effectively reduces interfacial tension to create stable oil-in-water emulsions. Particularly valued for its ability to stabilize challenging formulations including silicone-based products.

Summary

emulsifying surfactant emulsion stabilizing texture enhancer

Science

Mechanism of Action

Functions through its amphiphilic molecular structure, where the C12-14 secondary alkyl chain provides hydrophobic properties while the 7-unit polyoxyethylene chain offers hydrophilic characteristics. This dual nature reduces surface tension between oil and water phases, enabling stable emulsion formation and improved product texture and application properties.
