Functions:
Polyglyceryl-3 Methylglucose Distearate is a plant-based emulsifier, and sometimes emollient, seen in cosmetics and beauty products. It is considered a glyceryl ester, an ingredient composed of fat and oil that can be altered (to liquid, or solid) depending on temperature, according to CosmeticsCop.com. It combines Stearic Acid (a potential irritant) with the condensation product of Methylglucose and Polyglycerin-3.
Beyond its emulsifying and conditioning properties, Polyglyceryl-3 Methylglucose Distearate is also used as a sunscreen ingredient because of its ability to provide water resistance when serving as a lipid-based surfactant. However, it has a low resistance rate of about 50% - 65%
