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.

Method for thickening a cosmetic formulation using an alkali swellable emulsion of a polymer with amps and which is rich in acrylic acid

The present invention concerns the use of a specific copolymer to homogenize compositions that include coloring pigments and/or pearlescent pigments and film-forming polymers, as well as the cosmetic compositions containing said copolymer.

Copolymers in cosmetic compositions

The present invention relates to the use in a sunscreen formulation containing pigment particles as UV-filtering mineral agents, new additives as agents improving the UV-absorbing capacities of said formulations, as well as sunscreen formulations including such agents.

Agent for obtaining a stable aqueous composition comprising particles in suspension

The present invention concerns formulations containing one or more comb structure amphiphilic copolymers that are both rich in hydrophobic monomers and in polyalkylene glycol monomers. Cosmetic formulations. Methods of thickening.

Cosmetic formulation containing a non water-soluble amphiphilic copolymer as thickening agent

The invention relates to coating slip including latex comprising styrene and with a particle size centered around 100 nm, the use of latex as an agent for reducing the low shear gradient viscosity and increasing the low shear gradient viscosity, and methods thereof.

Use of a styrene latex 100 nm in size as a rheological agent in a paper coating, the paper coating, and the method for obtaining it

Cosmetic compositions for make-up containing acrylic comb copolymers having the advantage of increasing the intensity of the color produced by these compositions when they are applied to the skin or to keratin derivatives such as the hair or the eyelashes. Not only are the aesthetic properties conferred by these compositions thus improved, but their useful life is also increased, since they allow access to the desired shade (and good intensity) right from the first application.

Use of acrylic comb copolymers as a colour developing agent in cosmetic compositions

The present invention consists of the use, in a chlorinated and filled thermoplastic composition containing at least one chlorinated thermoplastic resin and at least one mineral filler, as an agent improving the thermal stability and UV resistance of the said composition, of a linear amphiphilic copolymer characterized in that: It also concerns a manufacturing process for a chlorinated and filled thermoplastic composition implementing the said copolymer, as well as the composition obtained directly by the said process.

Use of amphiphilic copolymers as agents for improving the thermal stability and UV resistance of chlorinated and filled thermoplastic materials, process for the fabrication of the said materials
