Use & Application
Cosmetic grade Span 80 is a classic W/O emulsifier for skincare creams, lotions, ointments and makeup products. It stabilizes water-in-oil emulsion systems, improves spreading property of formula and can be compounded with Tween series surfactants to adjust HLB value for different emulsion requirements. It also works as dispersant and skin conditioner in pigmented cosmetic formulas.
Food grade Span 80 serves as food emulsifier and stabilizer, used in bakery, margarine, chocolate and beverage. It prevents oil-water separation and improves texture of fat-containing food, complying with food additive regulations.
Pharmaceutical grade Span 80 is applied in topical ointments and medicinal emulsions as emulsifier and solubilizer, helping active ingredients disperse evenly in oil base.
Industrial grade Span 80 is used in coatings, paints, textile auxiliaries, lubricants and emulsion explosive. It functions as dispersant, antirust agent, softener and anti-static agent for various industrial formulations.
