Description

Sorbitan, Dioctadecanoate is a non-ionic surfactant and emulsifier derived from sorbitol and stearic acid. This compound is valued for its excellent stability and ability to form water-in-oil emulsions across a wide range of industrial applications. It is a critical ingredient for manufacturers in the personal care, cosmetics, food processing, and pharmaceutical industries seeking reliable and effective emulsification and dispersion.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments.
• Key component in food-grade emulsifier blends for baked goods, confectionery, and whipped toppings.
• Dispersing agent and viscosity modifier in industrial lubricants and metalworking fluids.
• Emulsifier for agricultural pesticides and herbicide formulations.
• Raw material in the synthesis of other specialty surfactants and esters.
• Additive in textile processing and fiber conditioning agents.
• Used in pharmaceutical ointments and topical delivery systems.
• Component in paint, ink, and coating formulations to improve pigment wetting.
