Brij™ C2 is an oil-in-water co-emulsifier for use in skin care, hair care, toiletries, and decorative cosmetics. The Brij™ Series of surfactants are polyoxyethylene vegetable-based fatty ethers derived from lauryl, cetyl, stearyl and oleyl alcohols. These materials are naturally derived, mild, and virtually odorless nonionic surfactants, and as a series, offer a diverse set of emulsifying characteristics allowing them to confer unique bodying, spreading and stabilizing properties to emulsions. Since the Brij™ surfactants manifest synergistic behavior, they can achieve even greater effects when used together. The extraordinary synergism shown by Brij™ blends is particularly evident in the case of difficult-to-formulate emulsions, such as clear gel microemulsions and alkali-based hair straighteners.
