Peregal Fatty Alcohol Polyoxyethylene Ether 0-25,O-20

Nonionic surfactants, which are favored in topical formulations because they have less potential for skin irritancy compared with ionic surfactants, and certain solvents alter the emulsions coating hair/wool, thereby allowing more drug to reach the skin surface. It is postulated that the mechanism by which skin penetration enhancers increase drug transport across the skin involves increasing the fluidity and/or the hydration of the polar head groups of the lipid bilayers (29).
ROKAnol C7 is a non-ionic surfactant belonging to the group of ethoxylated fatty alcohols (INCI name: Laureth-7.) The product co-creates a group of surfactants based on lauryl alcohol with C12-C18 carbon distribution.
