PEG-32 DISTEARATE.

Valuable CAS 9005-08-7 / SURFACTANT - EMULSIFYING

PEG-32 DISTEARATE is a versatile polyethylene glycol ester primarily functioning as an emulsifier and surfactant, crucial for creating stable mixtures of oil and water. It also contributes to product texture while offering mild humectant properties for enhanced skin hydration.

Summary

Emulsifying Surfactant Humectant Solvent Consistency Enhancer

Science

Mechanism of Action

This ingredient operates by reducing the surface tension between immiscible liquids, acting as a potent emulsifying agent to create stable cosmetic formulations. It further enhances products as a solvent, facilitating the dissolution and uniform blending of other components. On the skin, it can draw moisture, functioning as a humectant to support hydration, and within products, it acts as a consistency enhancer, particularly in solid or creamy textures.

The CIR Expert Panel concludes that PEG distearates, including PEG-32 DISTEARATE, are safe for use in cosmetics when formulated to be non-irritating. A critical concern for manufacturers is to ensure the minimization or removal of potential toxic impurities such as ethylene oxide and 1,4-dioxane. General caution is advised against applying products containing polyethylene glycols to broken or compromised skin, as they may penetrate damaged barriers.
