Description

Sorbitan (CAS NO 12441-09-7) is a versatile nonionic surfactant derived from the dehydration of sorbitol, forming a mixture of cyclic ethers. This compound is valued for its excellent emulsifying, stabilizing, and dispersing properties, making it a critical intermediate and functional additive in numerous formulations. It is essential for manufacturers in the food, cosmetic, pharmaceutical, and industrial chemical sectors seeking reliable performance and regulatory compliance.

Application

• As a key raw material in the synthesis of polysorbate (Tween) surfactants for pharmaceutical and cosmetic emulsions.
• Primary emulsifier and stabilizer in food products, such as baked goods, dairy analogs, and confectionery.
• Wetting and dispersing agent in industrial applications, including paints, coatings, and agrochemical formulations.
• Base ingredient for personal care products like creams, lotions, and makeup for its skin-friendly emulsification.
• Intermediate in the production of specialty esters used as lubricants and plasticizers.
• Component in household and institutional cleaning products for enhanced surface activity.
