Sorbitan Sesquicaprylate
What is Sorbitan Sesquicaprylate?
Sorbitan Sesquicaprylate is a non-ionic surfactant formed by esterifying sorbitol, a natural sugar alcohol derived from fruits and corn, with caprylic acid, a medium-chain fatty acid sourced from coconut or palm kernel oils. This creates a sesqui-ester structure, meaning approximately 1.5 fatty acid chains per sorbitol molecule, enhancing its emulsifying properties. In cosmetics, it belongs to the surfactant and emulsifier category, commonly found in cleansers, moisturizers, sunscreens, and makeup removers. It functions by reducing surface tension between oil and water phases, preventing separation and ensuring uniform texture and spreadability. As a mild cleansing agent, it helps remove impurities while respecting the skin's lipid barrier. Its biodegradable nature and low environmental impact make it popular in eco-friendly formulations, typically incorporated at effective yet gentle levels.
Benefits
Stabilizes oil-in-water emulsions for smooth, consistent product feel
