Abstract

1344253 Detergents containing enzymes GRINDSTEDVAERKET AS 19 April 1971 [23 Jan 1970 2 Sept 1970] 3476/70 and 42018/70 Heading C5D Spherical free-flowing particles of an enzyme product for incorporation in a detergent composition, are produced by suspending a pulverulent enzyme or mixture of enzymes in a molten non-ionic surfactant at a temperature between 35‹ and 90‹ C. and solidifying the mixture in the shape of particles by spray-cooling. The enzyme mixture is preferably homogenized and spray-cooled under conditions such that the particles solidify while they are still airborne. The ratio of enzyme to surfactant is from 1 : 10 to 1 : 1. The preferred surfactant is an ethoxylated fatty alcohol of melting point 45‹ to 55‹ C. A dyestuff may be present. Specifications 1,156,238 and 1,204,123 are referred to.
