CosmoSurf® DDG 28 is a naturally derived multidomain, film forming polymer with very good water resistance. It is made from natural and renewable starting materials based on dimer acid and branched alcohol end groups. It is not made using traditional free-radical based polymerization processes and is therefore free of residual vinyl-type monomers, initiators and catalysts. CosmoSurf DDG 28 is an excellent film-forming polymer that provides up to 80 minutes of water resistance in O/W and W/O emulsions and (alcohol-based) spray products. It offers pigment dispersion properties and homogeneous film formation upon application to wet skin, avoiding ‘white-out’ with a light, slight waxy feel that migrates to a dry alcohol feel.
