Rice Oil Glycereth-8 Esters

What is Rice Oil Glycereth-8 Esters?

Rice Oil Glycereth-8 Esters is a non-ionic surfactant and emulsifier derived from rice bran oil, obtained from the husk of Oryza sativa grains, chemically modified through esterification with glycereth-8—a hydrophilic molecule made from glycerol and ethylene oxide units. This process yields a pale yellow, viscous liquid with excellent solubility in water and oils, commonly incorporated into rinse-off products like facial cleansers, shampoos, body washes, and micellar waters. It functions by decreasing interfacial tension, enabling the formation of micelles that encapsulate dirt, sebum, and makeup for easy rinsing. Its balanced hydrophilic-lipophilic properties also aid in stabilizing emulsions, preventing phase separation, while its mild profile supports use in formulations targeting everyday cleansing without harshness.
