Description

Sorbitan Laurate CAS NO 1337-30-0 is a non-ionic surfactant derived from sorbitol and lauric acid, functioning as an effective emulsifier and solubilizer. This versatile compound is critical for creating stable, uniform mixtures of oil and water phases in complex formulations. It is an essential ingredient for manufacturers in the personal care, cosmetics, pharmaceutical, and food industries seeking reliable, high-quality emulsification.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments.
• Key ingredient in food-grade applications as an emulsifier (E493) for baked goods, confectionery, and whipped toppings.
• Used in pharmaceutical formulations for topical preparations to enhance drug delivery and stability.
• Acts as a dispersing agent and lubricant in industrial applications, including textile processing and metalworking fluids.
• Functions as a co-emulsifier and viscosity modifier in household and institutional cleaning products.
• Employed as a wetting agent in agricultural chemical formulations for improved pesticide and herbicide efficacy.
