VERFAHREN ZUR HERSTELLUNG VON MIT FUNKTIONALISIERTEN MOLEKÜLEN BELADENE OXID- MIKROKAPSELN UND DIE DARAUS ERHALTENEN PRODUKTE |
摘要 |
The present invention relates to a novel process for preparing sol-gel microcapsules loaded with up to 95% (w/w) functional molecules or substances and to the products obtained by said process. Said process is conducted in two steps: (a) creating an oil-in-water emulsion by emulsification of a water insoluble solution comprising the sol-gel precursors and the molecules to be loaded, in an aqueous solution under appropriate shear forces; (b) mixing and stirring said emulsion with an aqueous solution at a suitably selected pH to obtain loaded sol-gel microcapsules in suspension. The microcapsules so obtained can further be subjected to cycles of isolation and rinsing. Incorporation of the final product, either in the form of a suspension or a powder, in cosmetic formulations affords a transparent cream when applying to skin and has a smooth and pleasant contact. |
