Description

Sorbitan, Monooctanoate is a non-ionic surfactant derived from sorbitol and caprylic 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 hydrophobic and hydrophilic components in complex formulations. This product is essential for manufacturers in the personal care, food, and pharmaceutical industries seeking reliable, high-purity ingredients for their production processes.

Application

• As a primary or co-emulsifier in cosmetic and personal care products such as creams, lotions, and ointments.
• Used in food-grade applications as an emulsifier (E494) for baked goods, whipped toppings, and dessert mixes.
• Acts as a solubilizer for fragrances, essential oils, and fat-soluble vitamins in aqueous systems.
• Employed in pharmaceutical formulations for topical preparations to ensure uniform drug delivery.
• Serves as a dispersing agent and wetting agent in industrial applications, including agrochemicals and coatings.
• Functions as a lubricant and anti-static agent in textile and fiber processing.
