Abstract: 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, the EA can be water soluble or organic solvent soluble, in particular in ethanol. The microcapsule can also include an EA in which the water solubility is pH-dependent. Also, the core does not contain a metal oxide, and the coating does not include a disintegrant, such as sodium starch glycolate. Also disclosed is a process for preparing the microcapsules.
