Polyglyceryl-10 Stearate is a non-ionic surfactant produced through esterification between hydrophilic polyglycerol-10 and hydrophobic stearic acid. Thanks to its unique structure, it is a highly mild and safe multifunctional "green" raw material. In cosmetics and personal care products, it not only efficiently emulsifies oil and water phases to form stable emulsion systems but also exhibits excellent solubilization properties, aiding in the uniform dispersion of poorly soluble ingredients in formulations. Additionally, the stearic acid segment in its structure imparts a smooth skin feel and significant moisturizing effects, forming a protective film on the skin surface to lock in moisture. As a result, it is widely used in various products such as facial cleansers, lotions, creams, sunscreens, and makeup, making it a highly favored mild and efficient ingredient in modern formulations.
