Provided is a process for the preparation of methacrylate-based polymers soluble in aqueous medium, which can be used, in particular, as associative and non-associative thickeners.

Associative thickeners based on methacrylate

The present invention relates to a process for the preparation of polymers comprising carboxyl groups by emulsion polymerization and the use of the polymers obtainable by this process, for example as thickeners. Moreover, the invention relates to thickener dispersions obtainable by the process and to the use thereof for modifying the rheology of paper coating slips, textile printing pastes, drugs, cosmetic preparations, detergents, cleansing compositions, or foods.

Preparation of polyacrylates by emulsion polymerization

The invention relates to a polymer suited for modifying the styling performance and the rheology of a cosmetic preparation, a composition thereof, a method of making it as well as the use of said polymer and the composition respectively. The copolymer comprises at least one non-ionic ethylenically unsaturated C1-C4 (meth)acrylate as monomer A; an ethylenically unsaturated monomer B having as hydrogen bond donor an amide group, said ethylenically unsaturated monomer B being an ethylenically unsaturated monomer having a cyclic amide moiety, as monomer B1 and/or, an ethylenically unsaturated monomer having an acyclic amide group, as monomer B2; at least one ethylenically unsaturated carboxylic acid as monomer C; a macromonomer D; optionally at least one cross-linker E; and optionally at least one further monomer F.

Rheology modifying and setting polymer, composition thereof and method for making it

The present invention relates to aqueous preparations comprising at least one water-soluble or water-dispersible copolymer with cationogenic groups which comprises at least one monomer with at least one protonatable nitrogen atom and at least one further monomer copolymerizable therewith in copolymerized form, and at least one cosmetically acceptable carrier, where the pH of the aqueous preparation has a value in the range from pH 4 to pH 6.

Aqueous preparations comprising at least one water-soluble or water-dispersible copolymer with cationgenic groups

The present invention relates to an ampholytic copolymer, to polyelectrolyte complexes which comprise such an ampholytic copolymer, and to cosmetic or pharmaceutical compositions which comprise at least one ampholytic copolymer or one polyelectrolyte complex.

Ampholytic copolymer and use thereof

A cosmetic composition comprising a carboxyl-containing polysiloxane and a cosmetically acceptable auxiliary; in which the carboxyls are amidated by a compound selected from the group consisting of 2-amino-2-methyl-1-propanol, ethanolamine, morpholine and triethanolamine, and said amidation is up to 50 mol % of the carboxyls.

Use of carboxyl-containing polysiloxanes in cosmetic formulations

The inventions relates to carboxamidopolysiloxanes in cosmetic formulations, especially in skin-, hair-, nail- or mouthcare compositions. The cosmetic state is being improved: wet combability, combing force and static charge.

Carboxamidopolysiloxanes in cosmetic formulations

A description is given of water-soluble or water-dispersible polyaspartic acid derivatives, their preparation and their use in cosmetology, especially in hair cosmetology.
