What Is PEG-20 Methyl Glucose Sesquistearate?
PEG-20 methyl glucose sesquistearate is a complex mixture of a glycol with a fatty acid and glucose that functions multiple ways within cosmetic formulas. It can be used as a gentle cleansing agent, emollient, or oil-in-water emulsifier. In general, it helps deliver a soft afterfeel to skin.
As a raw material, PEG-20 methyl glucose sesquistearate is described as a pale yellow liquid and is derived from natural sources (corn).
In 2016, the Cosmetic Ingredient Review Expert Panel concluded PEG-20 methyl glucose sesquistearate is a safe cosmetic ingredient. Suppliers of this ingredient recommend usage levels range from 0.5% to 3%, depending on application.
