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,

Surface-modified metal oxides prepared by precipitation in the presence of a copolymer having N-vinylamide units, production processes and use thereof in cosmetic preparations

The invention relates to the use of polyacrylic acids which contain organic terminal groups containing sulphur, comprising at least two carbon atoms, having an average molecular weight Mof 5 000-30 000 g/mol and which are at least partially neutralized by a base which is selected from the group of alkali hydroxides and ammonia as auxiliary agents for wet grinding of calcium carbonate. The invention also relates to fine particle aqueous suspensions of calcium carbonate which are produced by wet grinding of calcium carbonate in the presence of said polyacrylic acids.

Use of polyacrylic acids as grinding aids for calcium carbonate

In the 2 &THgr; diffractogram of an enantiomerically pure crystalline (R)- or (S)-lipoic acid, the most intense reflection line in the range from 13&deg; to 30&deg; is that at 2 &THgr;&equals;23&deg;.

Crystal modification of lipoic acid

The invention relates to stable, pulverulent lycopene formulations, comprising lycopene having a degree of crystallinity of greater than 20%, processes for their preparation and their use as an additive to foodstuffs, cosmetics, pharmaceuticals and animal feedstuffs.

Stable, pulverulent lycopene formulations, comprising lycopene having a degree of crystallinity of greater than 20%

Storage-stable drug form

In a process for producing polyolefin foam particles, partially foamed particles are produced in a first stage by extrusion of a polyolefin containing solid blowing agents, and these are then further foamed in the second stage using steam.

Polyolefin particle foam

Branched polyamides are prepared by mixing A) from 10 to 99.7% by weight of a melt of a polyamide prepolymer having a viscosity number of from 40 to 90 ml/g with B) from 0.3 to 6% by weight of a polybasic carboxylic acid, where the number n of the free carboxylic acid groups is 3.ltoreq.n.ltoreq.10, and also C) from 0 to 80% by weight of further additives and processing aids, where the percentages by weight of the components A) to C) add up to 100%, and subsequently further condensing the mixture in the solid phase.

Preparation of branched polyamides

Packaging films are coated with a polyurethane which bears hydrophilic groups which make the polyurethane water-dispersible and which has a melting point of from 20.degree. to 70.degree. C., with the enthalpy of fusion in this temperature range being at least 20 J/g.
