Glycerol ethoxylate

Glycerol ethoxylate (CAS 31694-55-0), also known commercially as Glycereth-3, is a polyol derivative produced by ethoxylating glycerol to introduce hydrophilic ethylene oxide units. It functions as a humectant, emulsifier, and carrier across personal care, pharmaceutical, and industrial formulations. In cosmetic and skincare formulations, it retains moisture at the skin surface.

This material improves the spreadability of creams, lotions, and serums. Pharmaceutical manufacturers use it as a solubilizing carrier for active ingredients in topical and semi-solid dosage forms. It improves API dispersion without the need for harsh solvents. In coatings and adhesive systems, it acts as a reactive diluent and rheology modifier, adjusting viscosity and improving substrate wetting.

Food-contact and nutraceutical applications also draw on its carrier and humectant properties where approved grades are specified. Glycerol ethoxylate is supplied as a clear to slightly hazy viscous liquid. Cosmetic-grade material is available aligned with Glycereth-3 INCI specifications, while technical and industrial grades serve coatings and adhesive applications for various industrial sectors.

Purity levels and ethoxylation degree, typically around 3 moles EO, are key specification points buyers should confirm with suppliers to ensure the material meets their specific formulation needs.
