Abstract
Abstract An enzyme-containing detergent composition for a presterilization treatment of medical instruments and equipment, consisting of the following components, percent by weight: anionic surfactants: 4.0-6.0 sodium phosphate: 30.0-35.0 sodium silicate: 20.0-25.0 sodium carbonate: 19.0-22.0 soap comprising sodium salts of fatty acids: 2.0-4.0 enzymatic preparation: 0.5-2.0 sodium sulphate: the balance, the enzymatic preparation having the following composition, percent by weight: alkaline protease: 30-60 neutral protease: 27-45 elastase: 0.01-5.00 collagenase: 0.001-4.00 leucinaminopeptidase: 0.0001-0.011 carboxypeptidase: 0.04-0.15 fibrinolytic enzyme: 0.002-1.500 lipase: 0.5-2.0 amylase: the balance.
