Abstract: 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.

Abstract: 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, bya) dissolving one or more of the abovementioned xanthophylls in a water-miscible organic solvent or a mixture of water and a water-miscible organic solvent at temperatures above 30° C.,b) mixing this solution with an aqueous solution of a protective colloid, the solvent component being transferred into the aqueous phase, and the hydrophobic phase of the xanthophyll resulting as nanodisperse phasec) and, where appropriate, converting the dispersion which has formed into a water-dispersible dry powder by removing the solvent and the water and drying, where appropriate in the presence of a coating material,wherein casein or a caseinate is used as protective colloid in step b).

Abstract: 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.

Abstract: The use of organosulfur compounds is claimed for bathochromic shifting of the UV/visible absorption spectrum of carotinoids. Independent claims are included for: (A) complexes comprising one or more organosulfur compounds and one or more carotinoids, and (B) preparation of carotinoid formulations, which comprises dispersion of an organosulfur/carotinoid mixture in water or a protective colloid solution, followed by drying of the dispersion.
