| titleOfInvention | Metal-free water clarification composition |
| abstract | The present invention relates to a composition for clarification of water comprising: (i) 0.1 to 50% by weight of dry matter of anionic polymeric flocculant; (ii) 0.4 to 90% by weight of dry matter of an amphoteric copolymer having a weight-average molar mass from 2000 g/mol to 5,000,000 g/mol, said amphoteric copolymer comprising: (a) at least one anionic monomer selected from the group of ethylenically unsaturated acids, preferably (meth)acrylic acid; and (b) at least one cationic, amphoteric or zwitterionic monomer selected from the group of [N-substituted] (meth)acrylamide compounds comprising at least two quaternary nitrogen atoms; and (iii) 0 to 95% by weight of dry matter of inert filler; wherein the combination of the anionic polymer flocculant, the amphoteric copolymer and the inert filler constitutes at least 50% by weight to at least 70% by weight of the water clarification composition. |
