Description

Sorbitan, Trioctanoate is a non-ionic surfactant and emulsifier derived from sorbitol and caprylic acid. This compound is valued for its excellent lipophilic character and stability, making it a key functional ingredient in formulations requiring effective oil-in-water (O/W) emulsification. It is primarily utilized by manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable and versatile emulsifying agents.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and sun care products.
• Key ingredient in pharmaceutical ointments and topical preparations for stable emulsion systems.
• Used as a dispersing agent for pigments and actives in color cosmetics and makeup.
• Functions as a solubilizer for fragrances and essential oils in aqueous formulations.
• Employed in industrial applications as a lubricant additive or plasticizer in certain polymer systems.
• Acts as a wetting agent in agrochemical formulations for improved pesticide dispersion.
