Abstract

The invention belongs to the technical field of medical detergent, and relates to a basic enzyme-containing detergent and a preparation method thereof. The basic enzyme-containing detergent is composed of the following components in percentage by mass: 70-84% of water, 2-10% of inorganic base, 0.5-2% of surfactant, 10-24% of corrosion inhibitor, 2-5% of chelating agent and 1-4% of protease. The basic enzyme-containing detergent has the characteristics that the protease added in the basic enzyme-containing detergent can decompose fat and has good protein removal effect in alkalescent environment, thus the cleaning effect is improved; and the basic enzyme-containing detergent has the advantages of no corrosion, low foam amount, high wettability, low cost, high safety and good cleaning effect. The preparation method of the basic enzyme-containing detergent is simple and feasible, and is easy to implement and control.

Description

technical field [0001] The invention belongs to the technical field of medical detergents, and relates to an alkaline enzyme-containing cleaning agent and a preparation method thereof. Background technique [0002] At present, the commonly used detergent for cleaning surgical instruments in domestic hospital supply rooms is a neutral multi-enzyme cleaner. This product can clean surgical instruments and articles of all materials, but because of the addition of a variety of biological enzymes, the price is high, and many hospitals can only stay away from it. . In addition, through the actual inspection of many hospitals, it is found that 95% of conventional surgical instruments are made of stainless steel, and alkaline cleaners can be used to clean stainless steel instruments. However, pure alkaline substances have a good decomposition effect on fat. However, if it also has a decomposing effect on protein, the pH value of the cleaning agent must be increased, and if the pH v...
