Sorbeth-30 Tetraoleate

What is Sorbeth-30 Tetraoleate?

Sorbeth-30 Tetraoleate is a synthetic ingredient derived from sorbitol, a sugar alcohol, esterified with four oleic acid chains and ethoxylated with 30 ethylene oxide units, creating a water-soluble non-ionic surfactant. Commonly found in shampoos, body washes, facial cleansers, and emulsion-based moisturizers, it works by lowering surface tension between oil and water, allowing oils to disperse evenly and form stable mixtures. This functionality supports micellar cleansing systems that remove makeup and impurities gently, while enabling smooth textures in creams and lotions. Its hydrophilic-lipophilic balance makes it effective for oil-in-water formulations, contributing to product spreadability and rinse-off ease without residue. Authoritative reviews confirm its role in mild cleansing formulations due to its non-irritating profile in typical use levels.
