Sorbitan palmitate

Sorbitan palmitate is a nonionic surfactant and emulsifier obtained by esterifying sorbitol with palmitic acid. It is widely used in cosmetic and personal care formulations to stabilize emulsions and improve product texture. This ingredient helps blend oil and water phases, enhances spreadability, and contributes to a smooth, non-greasy skin feel. With its mildness and compatibility, it is suitable for creams, lotions, and various skincare applications.
