Description

Sorbitan Palmitate is a non-ionic surfactant derived from sorbitol and palmitic acid, functioning as a versatile emulsifier and stabilizer. Its primary value lies in its ability to create stable oil-in-water emulsions, making it a critical component for achieving consistent texture and shelf life in formulated products. This ingredient is essential for manufacturers in the cosmetics, personal care, food, and pharmaceutical industries seeking reliable and multifunctional excipients.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier and opacifier in creams, lotions, and makeup products to ensure smooth texture and stability.
• Food Industry: Used as an emulsifier (E495) in baked goods, whipped toppings, and confectionery to improve texture and volume.
• Pharmaceuticals: Serves as a non-ionic surfactant and emulsifying agent in topical ointments, creams, and oral suspensions.
• Industrial Applications: Functions as a lubricant additive, textile softener, and emulsifier in various chemical synthesis processes.
• Agricultural Adjuvants: Employed in pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
