Document Type and Number:
Japanese Patent JP2013545852
Kind Code:
A
Abstract:
Positive latex including an oil phase, an aqueous phase, at least one water-in-oil emulsifying system, and a linear, branched or cross-linked cationic polyelectrolyte resulting from the polymerization, for 100 mol %, of: a) a molar ratio >40% and @99% of monomer units originating from at least one cationic monomer; b) a molar ratio >=1% and <60% of monomer units originating from N-(2-hydroxyethyl)acrylamide; c) optionally, a molar ratio >0% and <30% of monomer units originating from at least one neutral monomer other than the N-(2-hydroxyethyl)acrylamide, on the condition that the molar ratio is strictly less than that of the monomer units originating from N-(2-hydroxyethyl)acrylamide; and d) optionally, a molar ratio >0% and @1% of a diethylene or polyethylene cross-linking monomer. A method for preparing and using the positive latex as a thickener for cosmetic or pharmaceutical compositions is also described.
