Microcapsules containing an oxidizable active, and a process for preparing the same

摘要

Disclosed is a microcapsule including a core having an oxidizable active (OA), the outer part of said core being in a solid form, and a water insoluble coating obtained from an encapsulating agent (EA), with the coating surrounding said core. In particular, there is disclosed a microcapsule wherein the EA is water soluble or organic solvent, in particular ethanol, soluble, or a microcapsule wherein said EA is an agent, the water solubility of which is pH-dependent. In particular, the core does not consist in or comprise a metal oxide, and the coating does not comprise a disintegrant, in particular sodium starch glycolate. Also disclosed is a process for preparing the microcapsules.
