STABILIZATION OF GRANULES

摘要

The present invention relates to granules comprising a core matrix and one or more coatings, wherein the core matrix comprises: An active compound, a synthetic polymer, where the amount of polymer added is 0.1 to 10 % by weight of the matrix, and one or more antioxidants and/or reducing agents, where the amount of antioxidant and/or reducing agent is 0.2 to 5 % by weight of the matrix. The active compound is an enzyme, e.g. savinase. The synthetic polymer is a polyvinyl polymer selected from the group consisting of PVP, PVA and copolymers thereof. A preferred antioxidant is sodium thiosulfate.
