    摘要： The present invention relates to coloured chlorhexidine antiseptic compositions, their use for dermal/topical application in the form of solutions or dispersions and the method for their preparation. The compositions comprise: from 50-85% v/v of a C1-C6 linear or branched alcohol; from 5-40% v/v of water; from 0.001% to 20% w/v of di(4-chloro-phenyldiguanido) derivative of formula (1) or a pharmaceutically acceptable salt thereof; from 0.001 % to 1% w/v of curcumin; wherein the v/v and w/v percentages are based on the total volume of the composition, and wherein the composition is free of THF. Preferably, they also comprise azorubine and/or β-carotene. The compositions are stable over time and suitable to colour and make identifiable areas disinfected with them.

    摘要： The invention relates to a polycationic polymer, comprising a cationic repeating unit C, comprising a positively-charged protonated guanidine group, and a negatively-charged counterion, balancing the positive charge of this guanidine group, wherein the dispersity (M w /M n ) of the polymer is 1,5 or higher, wherein the polycationic polymer comprises one or more than one further repeating unit, formed from a comonomer comprising a polymerizable group, wherein said at least one comonomer is a crosslinkable monomer, wherein the crosslinkable monomer is selected from benzophenone methacrylate (BPMA), benzophenone acrylate (BPA), a bifunctional acrylate or methacrylate, a trifunctional acrylate or methacrylate and a glycidyl acrylate or methacrylate.
    The invention further relates to a composition, comprising the polymer dissolved in a solvent, which solvent preferably is selected from an alcohol, water and/or a mixture thereof. The invention further relates to a product, comprising a functionalized surface, comprising a layer of the polycationic polymer and/or the composition, on the functionalized surface.
