Embodiment

[0060] Comparative Example Group A: Preparation of Enzyme Activity Protecting Agent Complex Borax-polyhydroxyl active protecting agent was prepared by using borax and glycerin. Both borax and glycerin were dissolved in water at 45°C for 30 minutes, followed by stirring at room temperature for an additional 15 minutes. The pH was adjusted to about 6.8 to 7.0 using hydrochloric acid. Enzyme was added last and stirred for 15 minutes to produce a clear storage stable formulation. The composition of the borax-polyhydroxy active protectant and related enzymes is summarized in Table 2A and identified as Reference Example 1.

[0061] The borax-silane polyether active protectant was prepared as follows. First dissolve borax in water at 45°C for 15 minutes. After a clear solution was obtained, the temperature was brought to 35°C and bis-PEG-18 methyl ether dimethylsilane was added and stirred for 30 minutes. The pH was adjusted to about 6.8 to 7.0 using hydrochloric acid and the enz...

[0102] Example-I: Performance Comparison of the Disclosed Compositions with Other Commercially Available Products

[0103] Table-10 shows the performance comparison of Example 146 with known commercially available samples (CIDEZYME xtra, J&J from Dr. Weigert, NEODISHER, Alkaline cleaner and RMEC 70500) on stainless steel plates for hard limescale cleaning. Example 146 was found to provide excellent results for hard scale inhibition and rust and gloss.

Abstract

The present invention relates to a cleaning composition for cleaning medical instruments. The cleaning composition of the present invention comprises: enzyme activity protectant compound; Enzyme system; One or more control polymers; Surfactant; Organic solvent; . Specifically, the cleaning composition of the present invention is a low-foaming multi-enzyme cleaner having excellent efficacy on enzymatic cleaning due to scaling, hard water scale inhibition, and rust inhibition. The composition also provides a gloss with excellent wetting and cleaning properties. The invention also relates to methods for the preparation of cleaning compositions and methods of cleaning medical instruments using the cleaning compositions of the invention.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from Indian Patent Application 3067 / CHE / 2014 filed on June 24, 2014, the disclosure of which is incorporated by reference in its entirety. technical field [0003] The present disclosure relates to cleaning compositions for cleaning medical instruments. In some embodiments, the cleaning composition is a low foaming multi-enzyme cleaner with excellent enzymatic cleaning efficacy. In some embodiments, the compositions inhibit hard water scale deposits and rust formation due to such scaling. In some embodiments, the compositions also provide a gloss with excellent wetting and cleaning properties. Background technique [0004] It is common practice to clean medical devices after use by one patient and before treatment on another patient. To minimize the possibility of cross-contamination, instruments used by one patient are advantageously cleaned separately from instruments used ...
