Description

Sorbitan, Diisooctadecanoate is a non-ionic surfactant derived from sorbitol and isostearic acid, functioning as a versatile emulsifier and dispersing agent. Its primary value lies in providing excellent stability and texture modification in complex formulations, particularly where oil-in-water emulsions are required. This product is essential for manufacturers in the personal care, cosmetics, and industrial lubricant sectors seeking reliable performance additives.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and sunscreens.
• Key ingredient in hair care products for conditioning and texture enhancement.
• Dispersing agent and viscosity modifier in industrial lubricants and metalworking fluids.
• Co-emulsifier in pharmaceutical ointments and topical delivery systems.
• Stabilizing agent for pigments and fillers in various coating formulations.
• Additive in textile processing aids for fiber lubrication and softening.
