Summary for Patent: 4,456,544

Title:	Enzyme-containing detergent composition for presterilization treatment of medical instruments and equipment
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.

Assignee:	Vsesojuzny Nauchno-Issledovatelsky Biotecknichesky Institut (Moscow, SU)
Application Number:	06/520,813
Patent Claims:	1. An enzyme-containing detergent composition for 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. 2. An enzyme-containing detergent composition as claimed in claim 1, wherein non-ionic surfactants are additionally present in an amount of 1-2% by weight of the anionic surfactants. 3. An enzyme-containing detergent composition as claimed in claim 2, wherein as said non-ionic surfactants use is made of a monoalkyl ester of polyethyleneglycol based on primary aliphatic alcohols; a polyoxyethyleneglycol ester of monoethanolamides of synthetic aliphatic acids.
