摘要： The invention concerns the use, in a composition for treating textile fibre articles in aqueous or moist medium, of an amphoteric polysaccharide, whereof the native skeleton is a polysaccharide consisting of a main chain comprising anhydrohexose units and branches comprising at least a neutral or anionic anhydropentose and/or anhydrohexose unit, the anhydrohexose and/or anhydropentose units being substituted of modified by groups bearing at least a (potentially) anionic load and/or at least a (potentially) cationic load, the degree of substitution or modification by the set of said groups bearing (potentially) anionic loads ranging between 0.01 and less than 3, with a ratio of the number of (potentially) anionic charges over the number of (potentially) cationic loads ranging between 99.5/0.5 to 30/70, as agent for preventing degradation and/or enabling to protect the colours of said articles and/or providing said articles with crease-resistant and/or softening properties.

摘要： The invention concerns an aqueous dispersion comprising photocatalytic titanium dioxide particles, an anionic water soluble dispersant of mole weight not more than 5000, and an ampholytic water soluble film-forming polymer whereof the anionic load is not less than the cationic load, the pH of the dispersion being not less than 3.

摘要： The invention concerns the use of at least a water soluble polymer obtained by copolymerising: at least an ethylenically unsaturated monomer (a) having a group capable of being protonized in the medium where it is to be used with: at least an ethylenically unsaturated monomer (b) bearing an acid character function copolymerisable with (a) and capable of being negatively ionized in the medium where it is to be used; and optionally at least an ethylenically unsaturated neutrally charged monomer (c), preferably bearing one or several hydrophilic groups, copolymerisable with (a) and (b), to improve the biocidal efficiency of biocidal compositions comprising a cationic biocidal compound.
