Concentrated multienzyme cleaning solution and preparation method thereof

Abstract

The invention discloses a concentrated multienzyme cleaning solution and a preparation method thereof, wherein the concentrated multienzyme cleaning solution is prepared from the following raw materials in parts by weight: 1 to 5 parts of organic preservative, 200 to 400 parts of surfactant, 20 to 65 parts of enzyme stabilizer, 40 to 80 parts of propylene glycol, 30 to 80 parts of triethanolamine, 10 to 60 parts of sodium sulfite, 0.1 to 5 parts of calcium chloride, 20 to 60 parts of sodium citrate, 10 to 65 parts of citric acid, 0.1 to 1 part of antifoaming agent, 30 to 80 parts of bio-enzyme, and appropriate deionized water; and the method for preparing the concentrated multienzyme cleaning solution comprises the following steps: dissolving the preservative into the propylene glycol, then adding the surfactant, the triethanolamine and the antifoaming agent into the obtained mixture so as to obtain a solution A; heating the deionized water, and dissolving the enzyme stabilizer, the sodium sulfite, the calcium chloride, the sodium citrate and the citric acid into the deionized water, then cooling the obtained mixture so as to obtain a solution bio-enzyme B; and finally, mixing the solution A and the solution B so as to obtain the finished product of the concentrated multienzyme cleaning solution. The concentrated multienzyme cleaning solution and the preparation method thereof have the advantages: the enzyme stabilizer is adopted to effectively protect the activity of the bio-enzyme, and used with the surfactant and the preservative, so that the obtained finished product is stable in performance, long in storage time and strong in capacity of decomposing biological tissues.

Description

technical field [0001] The invention relates to a washing liquid, in particular to a medical concentrated multi-enzyme washing liquid, and also relates to a preparation method of the washing liquid. Background technique [0002] Some surgical instruments and inspection tools used in the hospital need to be reused. These instruments will be contaminated with the patient's body fluids and tissues after contact with the patient. If they are not cleaned thoroughly, it will not only affect the disinfection effect, cause iatrogenic infection, but also shorten the service life of the instrument. affected. The knives, loading vehicles, and work clothes of the staff used in the slaughterhouse are all reused. If the cleaning of animal tissues and blood is not enough, it will not only affect the environmental sanitation of the slaughterhouse, but also provide a source of protection for the pathogens of zoonotic diseases. opportunity to spread. At present, these special items all rely...

Problems solved by technology

At the same time, various enzymes are in an active state in liquid detergents, and proteases can decompose and destroy other enzymes, and even decompose proteases themselves. Therefore, other enzymes and proteases are in the same system, and their biological activity is unstable. Due to protein variability or degradation by microorganisms or protease self-degradation, the shelf life will be short, which will affect the washing effect

The multi-enzyme detergent in solid form, although the enzymes do not interfere with each other, is good for storage, but when using it, the solid particles containing the multi-enzyme must be dissolved and dispersed in water to release the enzyme and generate activity, which is inconvenient to use. ;In addition, during the dissolution process, some enzymes have poor water solubility, which will affect the enzyme activity and the washing effect
