Abstract (en)

[origin: WO2012072931A1] The invention relates to positive latex including a straight, branched, or cross-linked cationic polyelectrolyte from the polymerization, in molar %, of: a molar ratio of greater than or equal to 70% and less than or equal to 99% of monomer units from at least one cationic monomer; b) a non-zero molar ratio of less than 20% of monomer units from N-(2-hydroxyethyl)acrylamide; c) a non-zero molar ratio of less than or equal to 15% of monomer units from at least one monomer of formula (I): A-C(=0)-0-[(CH2-CH(RI)-0]n-R, where n is, independently, a number between 1 and 50, A is an unsaturated aliphatic radical including 2 to 6 carbon atoms, R1 is a hydrogen atom, a methyl radical, or an ethyl radical, and R is a straight or branched, saturated or unsaturated aliphatic radical including 8 to 30 carbon atoms; d) optionally, a molar ratio of greater than 0% and less than or equal to 10% of monomer units from at least one neutral monomer other than said N-(2-hydroxyethyl)acrylamide, it being assumed that said molar ratio is strictly less than that of the monomer units from the N-(2-hydroxyethyl)acrylamide, and optionally, a molar ratio of monomer units from at least one neutral monomer other than said N-(2-hydroxyethyl)acrylamide; and e) optionally, a molar ratio of greater than 0% and less than or equal to 1% of a diethylene or polyethylene cross-linking monomer. The invention also relates to a method for the preparation and use of said positive latex as a thickener for cosmetic or pharmaceutical compositions.
