Japanese Patent JP2000508703
Kind Code:
A
Abstract:
Enzyme granules suitable for incorporating into detergents or cleaners are provided containing an enzyme, a carrier material and a granulation auxiliary containing phosphated starch. The phosphated starch preferably has a mean degree of phosphation ranging from 1.5 to 2.5. Carrier materials include starch, cereal flour, cellulose, alkali metal aluminosilicate, layer silicate and alkali metal salts. Enzymes include proteases, lipases, amylases and cellulases. A preferred carrier material contains water-swellable starch, sucrose, cereal flour and cellulose powder. The granulation auxiliary may contain a co-granulation auxiliary selected from polyethylene glycol having an average molecular weight of from 200 to 6,000, 1,2-propylene glycol and a poly-ethoxylate having a specified formula. Preferred granules have a mean particle size of from 0.3 to 3 mm. The granules are produced by forming a mixture containing an aqueous enzyme-containing liquid such as a concentrated fermentation broth, the carrier material and the granulation auxiliary, extruding the mixture, cutting the extruded mixture to obtain granules, and optionally spheronizing and drying the granules.
