The invention pertains to the field of aqueous thickening compositions, particularly for increasing the viscosity of an aqueous paint or varnish composition, a detergent composition or a cosmetic composition, in particular a cosmetic composition comprising ethoxylated surfactant compounds. The composition according to the invention comprises at least 40% by weight of water and combines a particular thickening compound and a nonionic compound comprising at least one hydrophilic saccharide group attached to at least one linear or branched hydrophobic chain.

Aqueous thickening composition

The present invention relates to novel associative thickeners pertaining to the HEUR category (Hydrophobically-modified Ethoxylated URethane), to intermediate aqueous formulations containing such thickeners, and to the final compositions, for example paint, lacquer, varnish or paper coating slip compositions.

Thickening agent for aqueous systems, formulations containing same and uses thereof

The invention relates to a rheology-modifying urethane compound. The compound comprising urethane functions of the invention can be prepared according to a method in several steps which use different compounds comprising isocyanate functions. For the preparation of the urethane compound according to the invention, a monoisocyanate compound, in particular a monoisocyanate compound resulting from the separate condensation of an asymmetric diisocyanate compound with a reactive compound, is reacted with an alkylene glycol compound in the presence of a polyisocyanate compound. The invention also provides coating compositions comprising mineral particles and a urethane compound according to the invention.

Rheology-modifying urethane compound

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.

Use of glycerol as an agent to improve the self-dispersing properties of a mineral material to be added to an aqueous composition

The present invention relates to novel associative thickeners belonging to the category of the HEURs (Hydrophobically modified Ethoxylated URethanes) comprising an associative compound of bicycloheptane type for thickening aqueous compositions, and also to formulations compositions comprising such thickeners and to the final compositions, for example paint, lacquer, varnish or paper coating color formulations.

Thickening agent for aqueous systems, formulations containing same and use thereof

The present invention concerns 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 significantly thicken an aqueous formulation with a low, medium and high shear gradient. The invention also concerns the compositions containing them and their uses in different formulations such as aqueous paints.

Non-ionic associative thickeners containing cyclohexylol alkyls, formulations containing them and their uses

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.

Associative acrylic thickening agent containing polyglycerols and its use to increase the open time of thin or thick films

The present invention relates to the use of a new polymeric aqueous emulsion for surface treating particles of mineral matter.

Use of a polymeric emulsion for the surface treatment of particles of mineral matter

The present invention concerns new associative thickening agents belonging to the category of HEURs (Hydrophobically modified Ethylene oxide URethane). These products contain an original associative monomer with a base of alkyl cyclohexanol alkoxylates. Their thickening power is equal to or greater than that procured by HEUR associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyl phenols, matching current market demand.

Associative non-ionic thickening agents containing alkyl cyclohexanol alkoxylates, their uses and formulations containing them

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.

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.

Associative ionic thickening agents containing alkylcyclohexanol alkoylates, their uses and formulations containing them

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.

Non-ionic associative thickeners containing alkyl cyclohexylols, formulations containing them and their uses

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.

Emulsion of an associative acrylic polymer polymerised in the presence of polyglycerols and its use as a thickening agent in an aqueous formulation

A HASE-type rheology modifier containing an associative monomer which is functionalised by a hydrophobic group of an oxo alcohol base is provided. A method to prepare the HASE rheology modifier and its use in a method to thicken and create a Newtonian rheological profile in an aqueous formulation such as a water based paint is also provided.
