PEG-140 GLYCERYL TRISTEARATE.

Valuable CAS 41080-66-4 / SURFACTANT - EMULSIFYING

PEG-140 Glyceryl Tristearate is a versatile ingredient that primarily functions as an emulsifier, crucial for creating stable formulations by blending oil and water components. Beyond its emulsifying capabilities, it contributes to desirable product texture and consistency, and possesses humectant properties to support skin hydration.

Science

Mechanism of Action

This ingredient operates as an emulsifying surfactant, effectively reducing the interfacial tension between immiscible oil and water phases, thereby creating stable emulsions. It additionally enhances the structural integrity and feel of a product as a consistency enhancer, while its humectant nature allows it to attract and retain moisture on the skin. Furthermore, in aqueous systems, it serves as an effective viscosity increasing agent.
