Sorbitan Trioleate
What is Sorbitan Trioleate?
Sorbitan trioleate is a non-ionic surfactant formed by esterifying sorbitol, a sugar alcohol from fruits, with oleic acid, an unsaturated fatty acid sourced from vegetable oils like olive or sunflower. This creates a lipophilic compound ideal for cosmetic formulations. Primarily used in oil-in-water and water-in-oil emulsions such as creams, lotions, cleansers, and shampoos, it functions by lowering surface tension between oil and water phases. This action forms a protective film at the interface, preventing separation and ensuring even texture and spreadability. Its surfactant properties also aid in gentle cleansing by enabling foam and rinse-off. With a low hydrophilic-lipophilic balance, it excels in water-in-oil systems, providing occlusive benefits for moisturizers. Overall, it supports product stability without altering sensory qualities significantly.
