Sorbitan Laurate In Cosmetics

Synthesized by the esterification of ethoxylated sorbitan with lauric acid, the sorbitan monolaurate is widely used as W/O emulsifier, stabilizer, lubricants, plasticizers, and desiccant in the medical and cosmetic industry. With the right use, sorbitan monolaurate can work perfectly as both cleansing agents and emulsifiers. However, it should be noted that the overuse of sorbitan monolaurate (amounts above 5%) may lead to unpleasant skin irritations.
