Abstract: The present disclosure relates to a method for improving the auto-dispersant characteristic in water of a mineral substance. The method includes the steps of dry-grinding, in the presence of a formulation, a mineral substance selected from a dolomite, talc, titanium dioxide, alumina, kaolin and calcium carbonate, wherein the formulation contains a polyglycerol and no glycerol.
Abstract: The present disclosure describes methods for improving the auto-dispersant characteristic in water of mineral substances, such methods involving dry-grinding of a mineral substance in the presence of a formulation. In some embodiments the formulation includes glycerol and at least one agent in aqueous or pure form. In other embodiments the formulation includes an aqueous polyglycerol.
Abstract: 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.
Abstract: The present invention relates to a new solvent-free preparation method of a (meth)acrylic acid polymer in solution, where said polymer has a molecular weight less than 8,000 g/mol and a polydispersity IP index between 2 and 3 by radical polymerisation, the polymers obtained by this means, and their applications in industry.

Abstract: 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.
Abstract: The present invention concerns weakly anionic polymers including their use in paper coatings, especially those intended for paper for inkjet printing. These additives provide the sought thickening function, while improving water retention very appreciably. The invention also concerns a method of manufacture of such coatings, together with the coatings obtained in this manner.
Abstract: The present invention pertains to the use, in the manufacture of an aqueous formulation with a hydraulic binder base, of a combination of at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one ASE acrylic polymer. This results in improving the workability of said formulation, without causing a segregation phenomenon.

Abstract: New associative thickening agents belonging to the category of HASEs (Hydrophobically modified Alkali-Soluble Emulsions). These products contain an original associative monomer with a base of alkylcyclohexanol akoxylates. Their thickening power is greater than the HASE associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyls phenols, matching current market demand.
Abstract: New associative thickeners of the HEUR type (Hydrophobically modified Ethylene oxide URethane) whose hydrophobic monomer is based on alkyl cyclohexylols. These are new polyurethanes that allow a broad thickening of a medium shear gradient aqueous formulation while limiting the increase in the low shear gradient viscosity. The invention also concerns the compositions containing them and their uses in different formulations such as aqueous paints.
Abstract: Emulsions containing acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, have a thickening power which is remarkably stable over time.
Abstract: 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.
Abstract: A method for manufacturing an aqueous suspension of calcium carbonate by grinding in an aqueous medium in the presence of an acrylic grinding aid agent and of an alkali carbonate salt. These salts enable the quantity of grinding aid agent used to be reduced, for an equivalent level of performance in terms of rheology and granulometry of the suspensions. The method includes a first step of manufacture of the alkali carbonate salt within the aqueous solution of acrylic polymer itself, through the addition of alkali hydroxide and bubbling of carbon dioxide.

Abstract: 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.
