CosmoSurf® DGSi, supplied by SurfaTech, is a film forming polymer with very good water resistance. It is 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 DGSi 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 includes a silicone group incorporated into the backbone, providing a silicone feel.
