CosmoSurf® CE-100 is a naturally derived, multidomain, polymer with some very good 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-100 provides up to 80 minutes of water resistance in O/W and W/O emulsions and (alcohol-based) spray products. It is designed to help avoid ‘white-out’ upon application to wet skin with a light, non-greasy feel.
