CosmoSurf® CE-140 is a naturally derived, multidomain, film forming polymer with water resistance. It is made from natural and renewable starting materials of based on citric acid and fatty alcohols. It is not made using traditional free-radical based polymerization processes and is therefore free of residual vinyl-type monomers, initiators and catalysts. CosmoSurf CE-140 is an excellent film-forming polymer that provides up to 80 minutes of water resistance in O/W and W/O emulsions. It is designed to help avoid ‘white-out’ upon application to wet skin with a light, slightly waxy feel.
