Problems solved by technology

However, if the heating temperature during use is higher than the cloud point of the enzyme-containing detergent or its dilution, the enzyme-containing detergent or its dilution will become translucent or opaque, which will inevitably affect the operator's observation and judgment of the instrument Cleaning conditions, and affect the final cleaning effect; more seriously, even cause sharp instruments to harm the operator
[0008] Furthermore, in the current prior art, methods for increasing the cloud point of detergents involve adding solubilizers such as glycerin, isopropanol, ethanol, methyl monobutyl ether, etc., but these methods require the addition of solubilizers in large quantities and Very limited improvement in the cloud point of detergents

Abstract

The present invention relates to an enzyme-containing detergent composition and application thereof, the enzyme-containing detergent composition comprising 1.0-10.0% by weight of hydrolase, 0.01-10.0% by weight of sarcosine or its derivatives, 1.0-20.0% by weight % by weight of nonionic or anionic surfactant, 0.0075-5.0% by weight of isothiazolinone or its derivatives and 45.0-95.0% by weight of water and optionally glycerin, propylene glycol or sodium borate compound. The present invention obtains an enzyme with a high cloud point (up to 80° C. or more) and good enzyme properties by including specific amounts of enzyme components, sarcosine or its derivatives, and surfactants and isothiazolinone or its derivatives. An enzyme-containing detergent composition with activity and storage stability, such an enzyme-containing detergent composition has a good balance between good enzyme activity, solution stability and high cloud point, not only can play a good cleaning effect, but also ensure Long-term and safe use characteristics. The enzyme-containing cleaner composition of the present invention can be used for cleaning medical devices.

Description

technical field [0001] The present invention relates to the field of enzyme-containing preparations, in particular to a multi-enzyme detergent composition containing sarcosine or its derivatives and its application. Background technique [0002] Cleaning and disinfection (or sterilization) are key steps in the post-use treatment of medical devices. For heavily contaminated instruments, pre-cleaning or pre-cleaning steps can significantly improve the success rate of subsequent cleaning and disinfection, prolong the service life of medical instruments, and reduce the risk of infection. Today, in the hospital disinfection supply center, endoscopy center, operating room decontamination center and other departments, enzyme-containing cleaners are widely used in medical equipment cleaning. According to incomplete statistics, the current sales of enzyme-containing detergents in the Chinese market are about 15 million US dollars, and it is expected to grow to 30 million US dollars ...
