Abstract

Composition enzymatique granulaire présentant une tendance réduite à former de la poussière et des résidus, ainsi que des caractéristiques améliorées de stabilité et de libération retard. Ladite composition granulaire possède un noyau, une couche enzymatique et une couche externe d'enrobage. La couche enzymatique et, de manière idéale, le noyau et les couches d'enrobage contiennent un polymère de vinyle. Des procédés de préparation desdites granules contenant des enzymes sont également décrits, lesdits procédés permettant une réduction considérable de la durée de préparation.
