Abstract
The present invention relates to a composition comprising a specific hyperbranched copolymer (HBC) of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine and the compound 1,3-propandiol and/or N-hydroxyoctanamide. It has been found that said hyperbranched copolymer synergistically enhances the antimicrobial action of a 1,3-propanediol and/or N-hydroxy-octanamide.
Claims19
A composition comprising:
- (a) a hyperbranched copolymer (HBC) of the monomers:
- (i) dodecenyl succinic acid anhydride;
