Macadamia Seed Oil Glycereth-8 Esters
What is Macadamia Seed Oil Glycereth-8 Esters?
Macadamia Seed Oil Glycereth-8 Esters is derived from oils pressed from the seeds of macadamia trees (Macadamia integrifolia or ternifolia), rich in palmitoleic and oleic fatty acids. Through esterification with glycereth-8—a short-chain polyethylene glycol ether of glycerol—this ingredient transforms the naturally hydrophobic oil into an amphiphilic compound with surfactant properties. Primarily featured in rinse-off products like shampoos, body washes, facial cleansers, and light emulsions, it reduces surface tension between oil and water, promoting effective dirt removal, foam formation, and phase stabilization. The retained lipid-like structure provides a smooth, non-drying after-feel, making it suitable for mild formulations that maintain skin barrier integrity during cleansing.
