Description

Sorbitan Sesquioleate is a nonionic surfactant derived from sorbitol and oleic acid, functioning as a versatile emulsifier and solubilizer. Its primary value lies in its ability to stabilize oil-in-water emulsions and enhance the compatibility of diverse ingredients within a formulation. This makes it a critical component for manufacturers in the cosmetics, personal care, and pharmaceutical industries seeking to create stable, high-quality products.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Solubilizer for fragrances, essential oils, and lipophilic active ingredients in clear gels and solutions.
• Key ingredient in hair care products like conditioners and styling aids for its lubricating and anti-static properties.
• Used in pharmaceutical topical preparations as an emulsifying and stabilizing agent.
• Additive in industrial applications such as textile processing, metalworking fluids, and agricultural formulations.
• Component in certain food-grade emulsifier blends (subject to specific purity grades and regulations).
