20130035401 | NOVEL SELF-REVERSIBLE REVERSE LATEX, AND USE THEREOF AS A THICKENING AGENT IN A COSMETIC COMPOSITION - A self-reversible reverse latex, and its use as a thickener. The self-reversible reverse latex includes: 50%-70% of a cross-linked polyelectrolyte obtained by the polymerization of a monomer of formula (I), with R1 being 8 to 20 carbon atoms and 1≦n≦30 for a neutral monomer, and a monomer having an acid function; 4%-10% of a water-in-oil emulsifier; 1%-10% of an oil-in-water emulsifier including a surface-active composition (C); 15%-45% oil; and 0%-5% water. Composition (C) is 10%-50% composition (C | 02-07-2013 |
