Description

Sorbitan Tristearate is a nonionic surfactant derived from sorbitol and stearic acid, functioning as a versatile emulsifier and stabilizer. Its primary value lies in its ability to create stable water-in-oil (W/O) emulsions and modify the crystallization behavior of fats. This makes it an essential ingredient for manufacturers in the food, cosmetics, and industrial sectors seeking to improve product texture, consistency, and shelf life. Sorbitan Tristearate CAS NO 26658-19-5 is particularly valued for its lipophilic character and reliable performance in complex formulations.

Application

• Food Industry: Acts as an emulsifier (E492) in baked goods, confectionery (e.g., chocolate), whipped toppings, and edible coatings to control fat crystallization and prevent bloom.
• Cosmetics & Personal Care: Used in creams, lotions, ointments, and deodorants as a W/O emulsifier, thickener, and opacifying agent to provide a rich, stable texture.
• Pharmaceuticals: Serves as an excipient in topical formulations and sustained-release drug delivery systems for its emulsifying and stabilizing properties.
• Industrial Applications: Functions as an anti-fogging agent in plastic films (e.g., PVC, polyethylene) and as a lubricant or release agent in various manufacturing processes.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and finishing aid to improve material handle and processing.
• Paints & Coatings: Used as a dispersing agent and flow improver to enhance the stability and application properties of oil-based systems.
