Valuable CAS 128973-72-8 / SKIN CONDITIONING, SURFACTANT - EMULSIFYING

METHYLSILANOL TRI-PEG-8 GLYCERYL COCOATE is a versatile cosmetic ingredient that functions as an emulsifier, skin conditioning agent, and texture enhancer. Derived from silicones and coconut oil fatty acids, it helps create stable formulations while contributing to skin health.

Summary

emulsifying skin conditioning texture enhancing

Science

Mechanism of Action

This ingredient primarily functions by reducing the interfacial tension between immiscible oil and water phases, thereby facilitating the formation and stabilization of emulsions. As a skin conditioning agent, it supports the skin's overall well-being, helping to maintain its good physiological condition and texture.

Safety Profile

CIR Status
Safe with restrictions
Max tested
10%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEGylated alkyl glycerides, a group including structurally similar PEG glyceryl cocoates, safe for use at current practices and concentrations when formulated to be non-irritating. A maximum concentration of 10% is recommended for leave-on products, informed by ocular and sensitization data. While no specific SCCS or FDA status is detailed for METHYLSILANOL TRI-PEG-8 GLYCERYL COCOATE, the FDA often defers to CIR for cosmetic ingredient safety. EWG notes higher concerns if used in inhalable product forms due to potential respiratory issues, or if contaminated with toxic impurities. SkinSAFE reports no known topical allergies.
