Glycerin monostearate polyethylene glycol ether

Glycerin monostearate polyethylene glycol ether (CAS 51158-08-8), commonly sourced under the designation PEG-20 glyceryl stearate, is a nonionic surfactant and emulsifier derived from glyceryl stearate and polyethylene glycol.

It stabilizes oil-in-water emulsions and improves skin feel in finished formulations, making it a practical choice for formulators balancing performance with mildness in various applications.

In personal care, it functions as a primary or co-emulsifier in lotions, creams, and moisturizers, contributing both emulsion stability and a humectant effect on the skin surface.

Shampoos and conditioning rinses use it to solubilize oils and improve spreadability without disrupting foam profiles. It is highly valued for its versatility across different cosmetic formats.

In home care and industrial cleaning products, it acts as a wetting and dispersing agent in liquid detergent systems. It helps maintain consistency and performance in complex chemical mixtures.

Textile processing operations apply it as a softening and surface-conditioning agent during finishing treatments to improve fabric handle and uniformity across various fiber types.

Glycerin monostearate polyethylene glycol ether is typically supplied as a paste or waxy solid, with liquid forms available depending on PEG chain length and specific formulation needs.

Standard supply grades include cosmetic-grade material meeting general purity requirements. Technical-grade material is available for industrial cleaning and textile end uses where specific standards are not required.
