Nanoparticulate preparations of pharmaceutical and cosmetic active substances with a core-shell structure, whereby the active substance is present in an X-ray amorphous form, together with a polymer matrix and the shell consists of a stabilizing sheathing matrix.

Nanoparticulate core shell systems and the use thereof in pharmaceutical and cosmetic preparation

A process is described for producing solid preparations of at least one water-soluble, sparingly water-soluble or water-insoluble active compound suitable for the food and animal feed sectors or for pharmaceutical and cosmetic applications. In addition, the invention relates to oily suspensions in which these preparations are present as disperse phase, and to the use of these preparations as additive to animal feeds, foods, pharmaceuticals and cosmetic preparations.

Production of solid preparations of water-soluble, sparingly water-soluble or water-insoluble active compounds

Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.

Method for producing polymer coated pigment particles by precipitation

A process for preparing a stable, aqueous dispersion or a stable water-dispersible dry powder of xanthophylls selected from the group consisting of astaxanthin, lutein and zeaxanthin, by

Stable, aqueous dispersions and stable, water-dispersible dry powders of xanthophylls, and production and use of the same

Dye-containing polymer particles of at least one dye in a matrix of an essentially water-insoluble polymer and having an average particle size within the range from 5 nm to 5 &#x3bc;m are prepared by a process which comprises precipitating the dye-containing polymer particles from a solution of the polymer and of the dye in a water-miscible organic solvent by addition of an aqueous phase thereto.

Polymer particles containing dye

Carotenoid aggregates are useful as colorants for foods and for cosmetic and pharmaceutical preparations.

Use of carotenoid aggregates as colorants

Production of dry powders of one or more oxygenated carotenoids

The present invention relates to a set of (co)polymers, dispersion formulations, solid solutions and formulation conditions able to disperse a dye selected from the group of a monoazo dye, quinophthalone dye and an anthraquinone dye in a stable nanoparticular form in an aqueous medium.

Surface active random radical (co)polymer and dispersion method for using the same

The invention relates to aqueous dispersions of sparingly water-soluble or water-insoluble organic UV filter substances, which comprise at least one sparingly water-soluble or water-insoluble organic UV filter substance as colloidally disperse phase in amorphous or partially amorphous form.

Aqueous dispersion of water-insoluble organic UV filter substances

The dyes have an average particle size within the range from 5 nm to 1 &mgr;m and a variance of less than 50%. They are especially useful for ink-jet ink preparations.

Precipitated water-insoluble colorants in colloid disperse form

Stable, aqueous dispersions and stable, water-dispersible dry xanthophyll powder, their production and use

Organosulfur compounds can be used in complexes with carotenoids for effecting a bathochromic shift in the absorption bands of carotenoids in the UV/vis spectrum. Carotenoid formulations comprising these complexes, a process for preparing these formulations and their use in the food, cosmetics and pharmaceutical sectors are described.

Use of organosulfur compounds for effecting a bathocromic shift in the UV/vis absorption bands of carotenoids

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%
