The invention relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically copolymerizable monomer mixture designated as monomer C, whereby at least one of monomers C yields a homopolymer with a glass-transition temperature lower than 30&#xb0; C., with the provision that the wt. %'s total 100. The radical polymerization is carried out in the presence of alkane thiols with a C chain length of C 14 to C 22. The invention also relates to acrylate polymers comprising a K-value ranging from 10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically copolymerizable monomer mixture designated as monomer C, whereby at least one of monomers C yields a homopolymer with a glass-transition temperature lower than 30&#xb0; C., with the provision that the wt. %'s total 100. The radical polymerization is carried out in the presence of alkane thiols with a C chain length of C 10 to C 22 followed by a hydrogen peroxide treatment. The invention also relates to the use of these acrylate polymers as film formers as well as to their use in cosmetic preparations.

A cosmetic composition comprising at least one water-soluble or water-dispersible polymer which comprises, in copolymerized form,

Cosmetic composition with water-soluble or water-dispersible polymers

The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.

Hydrolytic preparation of titanium dioxide pigments

Ferromagnetic pigments

Metal oxide-doped zinc oxide pigments are produced by processing an oxide, carbonate, hydroxide of hydroxycarbonate of zinc in the presence of water and an oxide, carbonate, hydroxide, hydroxy-carbonate, oxalate or formate of the doping metal into a paste using formic acid or oxalic acid in an amount which is at least sufficient for converting the oxides, carbonates, hydroxides or hydroxycarbonates mentioned into formates or oxalates, drying, grinding and calcining at from 700.degree. to 1100.degree. C. in an inert gas atmosphere.
