Medium alkaline powdered or pelletised cleansing agent compsn. contain proteolytic enzymes, opt. mixed with amylolytic enzymes, in addn. to non-ionic and anionic weting agents, complex-formers such as Na tripolyphosphate and/or Na gluconate, foam inhibitors, enzyme activators and fillers, e.g. Na2SO4 and soda. Powdered cleansing agents contain esp. 50000 DU protease and 1500 AE amylese/g prod. They can be used as 0.5-5 (1-2)% solns. at pH 9-11 and 65-70 degrees C, having a protease activity of 100000-250000 DU/l and an amylase activity of 6500-3000000 AE/l. Enzyme dosage pellets have a higher enzyme concn., esp. 80000-500000 (300000) DU protease and 5000-60000 (6500) AE amylase/g prog. They are used to replenish enzymes in fresh or spent cleansing soln. or as additives to cleansing solns. consisting of 0.1% aq. alkali soln. and complex formers. |
