    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).

    Abstract: The present invention relates to surface-modified nanoparticulate metal oxides where the metal is chosen from the group consisting of aluminum, cerium, iron, titanium, zinc and zirconium, wherein the surface modification comprises a coating with a copolymer P comprising, as monomers, A) 1 to 99 mol % of a N-vinylamide N-vinylpyrrolidone and B) 99 to 1 mol % of a monomer comprising, per molecule, a free-radically polymerizable α,&bgr;-ethylenically unsaturated double bond and an anionogenic and/or anionic group, with the proviso that the copolymer P must comprise no further monomers chosen from the group consisting of C8-C30-alkyl esters of monoethylenically unsaturated C3-C8-carboxylic acids, N-alkyl- or N,N-dialkyl-substituted amides of acrylic acid or of methacrylic acid with C8-C18-alkyl radicals, or vinyl esters of aliphatic C8-C30-carboxylic acids.
