    Abstract: An ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A) (in wt.%) (50-99.5), an ethylenically unsaturated compound chosen from specific esters (0.5-50) (monomer B), and an optional monomer (monomer C) (up to 20) are polymerized in aqueous medium in the presence of foam inhibitor(s), to prepare an aqueous copolymer solution. An ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A) (in wt.%) (50-99.5), ethylenically unsaturated compound (0.5-50) (monomer B), and an optional monomer (monomer C) (up to 20), are polymerized in an aqueous medium in the presence of at least one foam inhibitor, to prepare an aqueous copolymer solution. The monomer (B) is chosen from esters of ethylenically unsaturated monocarboxylic acids and monoesters and diesters of ethylenically unsaturated dicarboxylic acids with an amine containing at least one hydroxyl group.

    Abstract: The present invention relates to the use of, if appropriate present in the form of an aqueous dispersion, polymers of ethylenically unsaturated anionic monomers for modifying the rheology of aqueous, alcoholic or aqueous/alcoholic cosmetic or dermatological compositions. The polymers are obtainable by free-radical emulsion copolymerization of water-soluble inorganic monomers in aqueous phase in the presence of, in each case, at least one stabilizing polymer of groups a) and b). The emulsion polymers are exceptionally suitable for thickening cosmetic or dermatological preparations based either on water or on alcohols.

    Abstract: Use is claimed as a rheological modifier for hair cosmetics of an ampholytic copolymer with a molar excess of anionogenic/anionic groups over cationogenic/cation groups or vice-versa, the copolymer being obtained by radical polymerization of specified unsaturated compounds optionally in presence of a silicon compound containing a polyether group and/or a radically polymerizable olefinically unsaturated double bond. Use is claimed as a rheological modifier for hair cosmetics of an ampholytic copolymer with a molar excess of anionogenic/anionic groups over cationogenic/cation groups or vice-versa, the copolymer being obtained (optionally in the presence of a silicon compound containing a polyether group and/or a radically polymerizable olefinically unsaturated double bond) by radical polymerization of (A) a compound with a radically polymerizable alpha ,beta -unsaturated double bond and an anionogenic and/or anionic group; (B) a compound like (a) but having cationgenic/cationic rather than anionogenic/anionic groups; and (C) a radically polymerizable crosslinking compound with >=2 alpha ,beta -unsaturated double bonds. Some of the copolymers are also claimed per se (see also the abstract for ).
