Description

Sorbitan, Triisooctadecanoate is a nonionic surfactant and emulsifier derived from sorbitol and isostearic acid. This compound is valued for its excellent lipophilic character and stability, making it a key ingredient for creating water-in-oil emulsions and solubilizing lipophilic substances. It is primarily needed by formulators in the cosmetics, personal care, and industrial lubricant sectors seeking reliable and versatile emulsifying agents.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments (water-in-oil type).
• Key component in hair care products and makeup formulations for texture and stability.
• Co-emulsifier and dispersing agent in industrial lubricants and metalworking fluids.
• Additive in textile processing for fiber lubrication and softening.
• Emulsifier for agricultural pesticides and coatings.
• Used in plastic and polymer formulations as an internal lubricant or antistatic agent.
