Product Usage
Glycerol monostearate (CAS No. 123-94-4) is a high-value multi-purpose industrial material, renowned for its top-tier emulsifying, dispersing and stabilizing performance that makes it an indispensable ingredient across countless industries. In food production, it acts as a premium emulsifier that perfectly blends oil and water phases in margarine, shortening and other products. It keeps baked goods fresh longer by slowing down staling to extend shelf life, and works as a smooth processing lubricant to boost efficiency in candy manufacturing.
For cosmetics brands, it is a go-to emulsifier for lotions and face creams: it locks in long-term emulsion stability, while adding extra moisturizing benefits and giving formulations a rich, comfortable texture. In pharmaceutical manufacturing, it serves as a trusted excipient for creams and ointments, and can be formulated into sustained-release systems to deliver consistent, long-acting drug performance.
It also brings outstanding value to other industrial sectors: it adds reliable antistatic and lubricating properties to plastic products, makes textiles softer, more water-resistant and less prone to static, and acts as a professional fatliquoring agent in leather processing to make finished leather far softer and higher in quality.
