Description

Sorbitan, Tridodecanoate is a non-ionic surfactant and emulsifier derived from sorbitol and lauric 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 emulsification. It is primarily utilized by manufacturers in the personal care, cosmetics, and specialty chemical industries to create stable emulsions, improve texture, and enhance product performance.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Stabilizing agent for water-in-oil (W/O) emulsion systems in personal care products.
• Key ingredient in makeup formulations, including foundations and lipsticks, for smooth application.
• Used as a dispersing agent for pigments and fillers in various industrial applications.
• Functional component in textile auxiliaries and fiber lubricants.
• Intermediate in the synthesis of other specialty surfactants and esters.
