PEG-175 DISTEARATE.

Valuable CAS 9005-08-7 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

PEG-175 Distearate is a polyethylene glycol derivative primarily functioning as a versatile surfactant. It effectively stabilizes oil and water components in formulations, enhances product texture, and contributes to skin hydration.

Summary

Emulsifying Viscosity Controlling Cleansing Solubilizing Humectant

Science

Mechanism of Action

This ingredient acts as a surfactant by reducing the interfacial tension between immiscible liquids, allowing oil and water to form stable emulsions. Its unique molecular structure, possessing both lipophilic and hydrophilic segments, facilitates this emulsification. Beyond stabilization, it is a viscosity-controlling agent, lending desired consistency to formulations, and also functions as a humectant, assisting the skin in retaining moisture.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded PEG-175 Distearate is safe for use in cosmetic formulations when properly formulated to be non-irritating. PEGs and their derivatives typically demonstrate low acute and chronic toxicities, posing minimal ocular or dermal irritation, and do not readily penetrate intact skin. The potential for sensitization on healthy skin is negligible. However, due to absorption concerns, it must not be applied to damaged skin. Manufacturers are advised to minimize impurities such as ethylene oxide and 1,4-dioxane.
