PEG-5 GLYCERYL TRIISOSTEARATE.

Valuable CAS 86846-21-1 / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PEG-5 Glyceryl Triisostearate is a multifunctional ester prized for its ability to enhance skin texture and stabilize formulations. It acts as an emollient, promoting soft and smooth skin, while also serving as an effective emulsifier and solubilizer.

Summary

emollient emulsifying surfactant solubilizer solvent

Science

Mechanism of Action

This ingredient functions primarily as an emollient, delivering a softened and smoothed sensation to the skin. Its molecular structure classifies it as a surfactant, featuring both lipophilic (oil-attracting) and hydrophilic (water-attracting) segments. This characteristic enables it to significantly decrease the interfacial tension between otherwise immiscible liquids, facilitating the formation and stability of oil-in-water emulsions. Furthermore, it acts as a solubilizer and solvent, aiding in the homogeneous dispersion of various components within a formulation.

The Cosmetic Ingredient Review (CIR) Expert Panel, in a comprehensive evaluation of PEGylated alkyl glycerides, determined this class of ingredients safe for use in rinse-off products. For leave-on applications, they are considered safe at concentrations up to 10%, provided the finished formulation is proven non-irritating. The US FDA has also designated this ingredient as Generally Recognized As Safe (GRAS) for use as a food additive. Environmental Working Group (EWG) data indicates a low concern for potential cancer, allergies, immunotoxicity, and developmental or reproductive toxicity.
