| 20140112966 | METHOD FOR THICKENING A COSMETIC FORMULATION USING AN ALKALI SWELLABLE EMULSION OF A POLYMER WITH AMPS AND WHICH IS RICH IN ACRYLIC ACID - Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin. | 04-24-2014 |
| 20140120049 | COMB POLYMERS FOR THE HAIR - Utilisation of (meth)acrylic comb copolymers with side chains of the hydroxy and alkoxy polyalkylene glycol type in which are present both ethylene oxide and propylene oxide links. These copolymers give a styling effect and an elimination of rinsing. The invention also relates to a cosmetic formulation containing such structures as well as a hair treatment process based on this formulation. | 05-01-2014 |
| 20140178485 | ACTIVE AGENT MICROPARTICLES - The present invention concerns polymeric-enveloped microparticles including at least one HASE type acrylic copolymer, at least one solid-liquid phase change material with a phase transition temperature ranging from 20 to 90° C., and at least one active agent. In particular, the microparticles include at least one HASE type acrylic copolymer including at least one anionic monomer with a polymerizable vinyl group and a carboxyl group, at least one non-ionic hydrophobic monomer with a polymerizable vinyl group, and at least one alkoxylated associative macromonomer with a polymerizable vinyl group and a hydrophobic hydrocarbon chain. | 06-26-2014 |
| 20140238272 | HYDROPHOBIZATION AGENT AND USE FOR THE SURFACE TREATMENT OF MINERAL MATTER PARTICLES - The present invention relates to a new mineral matter particle hydrophobization agent and to its various uses for the surface treatment of mineral matter particles. | 08-28-2014 |
| 20140296432 | ASSOCIATIVE ACRYLIC THICKENING AGENT CONTAINING POLYGLYCEROLS AND ITS USE TO INCREASE THE OPEN TIME OF THIN OR THICK FILMS - The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives. | 10-02-2014 |
