Description

Sorbitan, Tris[(Z,Z,Z)-9,12,15-Octadecatrienoate] is a nonionic surfactant derived from sorbitol and linolenic acid, functioning as a versatile emulsifier and solubilizer. Its core value lies in its ability to stabilize complex formulations, particularly those containing sensitive or highly unsaturated components. This product is essential for manufacturers in the cosmetics, nutraceutical, and specialty chemical industries seeking high-performance, plant-derived ingredients.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and serums.
• Solubilizing agent for fat-soluble vitamins (A, D, E, K) and botanical extracts in clear liquid formulations.
• Key ingredient in nutraceutical and dietary supplement delivery systems, such as softgel capsules.
• Stabilizing agent in pharmaceutical topicals and ointments.
• Dispersant and wetting agent in agrochemical formulations.
• Intermediate for the synthesis of more complex specialty surfactants and esters.
• Additive in lubricants and industrial fluids to improve oil compatibility.
