Abstract:
The invention relates to polymer products that can be obtained by mixing (A) polymers, obtained by the radical polymerisation of (A-1) ethylenically unsaturated monomers in the presence of (A-2) unsaturated polyalkylene glycols, with (B) silicones, at a temperature greater than or equal to 30 °C. The invention also relates to a method for producing said polymer products, in addition to their use in cosmetic preparations, in particular haircare preparations.
Abstract:
The invention relates to the use of copolymers which comprise a) 60 to 99 % by weight of N-vinylcaprolactam; b) 1 to 40 % by weight of at least one monomer b) selected from the group including: b1) C8-C30 alkyl esters of monoethylenically unsaturated C3-C8 carboxylic acids; b2) N-alkyl- or N,N-dialkyl-substituted amides of the acrylic acid or the methacrylic acid with C8 to C30 alkyl groups; b3) the vinyl esters of aliphatically unbranched C8-C30 carboxylic acids; b4) the C8-C30 alkyl-vinyl ethers, as solubilizers for substances that are difficult to dissolve in water.
Abstract:
The invention relates to the use of copolymers obtained by radically polymerising a mixture of i) 30-80 % by weight N-vinyllactam, ii) 10-50 % by weight vinylacetate, and iii) 10-50 % by weight polyether, wherein the sum of the components i), ii) and iii) is equal to 100 % by weight as solubilisers for poorly water-soluble substances.
Abstract:

Abstract:
La invencion se relaciona a un metodo para producir mezclas de polimero, que son adecuadas para el uso como auxiliadores de filtro, de poliestireno y polivinilpirrolidonas insolubles en agua reticuladas procesando los componentes en un extrusor. La invencion se caracteriza porque el poliestireno se funde en un extrusor, entonces se mezcla con polivinilpirrolidona, y se agrega agua a la mezcla de los componente que tienen 0.1 a 10% en peso con respecto a la cantidad total de poliestireno y polimero de palomitas de maiz, en donde la mezcla se extruye y pulveriza.
Abstract:
Una composicion de principio activo o de compuesto eficaz, que contiene por lo menos un principio activo o compuesto eficaz dificilmente soluble en agua, y por lo menos un polimero hiper-ramificado.
Abstract:
The invention relates aqueous skin or hair cosmetic preparations which comprise at least one polymer A which contains, in a polymerised form, at least one ester of a (meth)acrylic acid, at least one olefinically unsaturated, radically polymerisable anionogenic or anionic compound, at least one olefinically unsaturated compound containing urethane groups and which does not contain any silicone groups and, optionally, additional radically polymerisable compounds.
Abstract:
Active/effective substance composition (I) comprises: (1) at least one nitrogen-containing hyperbranched polymer (A); and (2) at least one active/effective substance (B), which exhibits a solubility below 10 g/l in water at 25[deg]C and 1013 mbar. Independent claims are also included for the following: (1) an aqueous composition of (I) comprising an aqueous medium as continuous phase and at least one (B), which is soluble or dispersed in the continuous phase; (2) a composition in the form of redispersible solid material in aqueous media, obtained by drying an aqueous active or effective substance composition; (3) preparation of aqueous (I); and (4) a cosmetic, pharmaceutical or plant protecting agent comprising (I) and optionally at least one further active or auxiliary material; (5) use of at least one (A) as a solubilizer to prepare aqueous compositions of (B).
