发明名称 CAROTINOIDS AND RETINOIDS IN FINELY DIVIDED FORM
摘要 Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG C. to 200 DEG C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.
