20130210932 | NOVEL CATIONIC THICKENERS USABLE OVER A WIDE PH RANGE, METHOD FOR THE PREPARATION THEREOF, AND COMPOSITION CONTAINING SAME - 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. | 08-15-2013 |
20130197101 | NOVEL ELECTROLYTE-RESISTANT CATIONIC THICKENERS USABLE OVER A WIDE PH RANGE, METHOD FOR PREPARING SAME, AND COMPOSITION CONTAINING SAME - Positive latex including a straight, branched, or cross-linked cationic polyelectrolyte from the polymerization, in molar %, of: a molar ratio ≧70% and ≦99% of monomer units from at least one cationic monomer; b) a non-zero molar ratio <20% of monomer units from N-(2-hydroxyethyl)acrylamide; c) a non-zero molar ratio ≦15% of monomer units from at least one monomer of formula (I): A-C(=0)-0-[(CH | 08-01-2013 |
