Sorbitan fatty acid ester (SPAN) is a non-ionic surfactant with fatty acid group as hydrophobic part and sorbitol as hydrophilic part.
Industrial and food grade products comply with national standards, pharmaceutical grade compliance USP24.
The plate is white or yellowish wax, flake, powder (≥100 mesh). Soluble in hot ethanol, ether, methanol and carbon tetrachloride, slightly soluble in ether, petroleum ether, can be dispersed in hot water, with strong emulsification, dispersion, lubrication, can be mixed with all kinds of surfactants. The emulsifier plate is mainly used as antistatic agent and soft oiling agent for acrylic fiber. It is used as emulsifier and stabilizer in food, medicine, pesticide, cosmetics, coating and plastic industry.

More than 30,000 tons of food emulsifiers have been approved for use in China, and the world's consumption of food emulsifiers has exceeded 400,000 tons. The varieties and dosage of food emulsifier products in China are far less than those in foreign countries. Developing new varieties of emulsifiers with various functions and enriching the intrinsic functions of Chinese food emulsifiers should become the idea of the industry in developing new products.
