C11-15 PARETH-15.

Valuable CAS 173244-48-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A versatile nonionic surfactant that excels at creating stable emulsions and solubilizing hydrophobic ingredients in skincare formulations. With an HLB value of 14.7-16.7, it effectively bridges oil and water phases while maintaining gentle cleansing properties suitable for sensitive skin.

Summary

surfactant emulsifying cleansing solubilizing

Science

Mechanism of Action

Functions by reducing interfacial tension between oil and water phases through micelle formation, enabling stable oil-in-water emulsions and enhanced solubility of lipophilic actives like vitamins and botanical oils

Key findings

  1. 01 Patent studies demonstrate 1.0% concentration effectively solubilizes poorly water-soluble actives like progesterone, creating stable 6-15 nm macromolecular assemblies
  2. 02 CIR assessment confirms safe use at 0.1-0.8% as co-emulsifier in personal care products with no sensitization reported
