Glyceryl Stearate SE 40%-50% (Glyceryl monostearate GMS 40% SE, CAS 11099-07-3) is self-emulsifying glyceryl monostearate mixture, composed of glyceryl monostearate plus minor portion of alkali stearate (sodium/potassium stearate). Different from non-self-emulsifying GMS (CAS 31566-31-1 and pure CAS 123-94-4), it delivers O/W emulsifying capacity without extra co-emulsifier, widely used for cosmetic creams and lotions. TNJ Chemical is a professional manufacturer and exporter since 2001. We guarantee high quality products, competitive prices and thoughtful service.
