Abstract
Enzyme granules, particularly for detergent compositions, are prepared having a granule core of solid material carrying an enzyme and a solid coating of plasticized resin free of the enzyme. The plasticized resin can be dextrin or sodium lignosulphonate containing a plasticizer such as glucose, sucrose urea, glycerol or ethylene glycol. The granules are made by spraying the enzyme-containing core with a concentrated aqueous solution of the plasticized resin.
