Problems solved by technology

However, these types of surfactants generally have a cloud point below 40°C, and when the diluent temperature is above 40°C, the solution becomes cloudy
Therefore, manual cleaning is very inconvenient
The medical device will not be visible in the diluted solution, which may injure the operator's hand, and some small parts may be lost because they are not easy to see

example

[0068] The invention is further illustrated by the following examples, which should not be construed as limiting the scope of the invention. All parts and percentages are by weight unless otherwise indicated.

[0069] The following starting materials were used for the experiments in the examples of the present invention.

[0070] Table 1

[0071]

[0072]

[0073] Chemical reagents except those listed in Table 1 were from common commercial sources.

example 1

[0075] Add 0.1 g of LFW 1064, 0.1 g of Glucopon 425N and 0.5 g of SXS93 to 99.3 g of distilled water, and stir at room temperature for 20 minutes to obtain 0.1% by weight of LFW 1064, 0.1 Cleansing composition of Glucopon 425N and 0.5% SXS93 by weight. Then, according to the above Test Methods Procedures and standards described in section, performance characterization of cleaning compositions ( Foam level, cloud point, cleaning efficacy, corrosivity, degreasing potency, and compatibility with enzymatic cleaners ). The results are shown in Table 2.

[0076]From the result of table 2, it can be clearly seen that: when the weight ratio of component B and component C is 1: 5, and the weight ratio of component A and component (B+C) is 1: 6, in example 1 The resulting cleaning compositions achieve good performance in terms of foam level and cloud point.

Abstract

A cleaning composition comprises A) a fatty alcohol-alkylene oxide copolymer, B) a glycoside, and C) a benzene sulfonate, wherein, the weight ratio of the component B and the component C is less than or equal to 5 : 1. The cleaning composition can be used as a detergent for cleaning medical appliances.

Description

technical field [0001] The present invention relates generally to the field of medical instrument cleaning, and in particular, to cleaning compositions for cleaning medical instruments. Background technique [0002] Medical device cleaning is very important for infection control in hospitals. There are many different kinds of detergents for cleaning medical instruments, such as enzyme-containing detergents, alkaline detergents, acidic detergents, etc. (see US 6562296; US20090061017; and WO8809369). [0003] In hospitals, medical instruments are cleaned automatically or manually. For automated cleaning, jet cleaning has become a common method, which uses water pressure to remove dirt from the object to be cleaned. Conventional surfactants have a problem of high foaming power when used in this cleaning method. Large amounts of foam weaken the spray pressure and lead to unsatisfactory cleaning results. What's more, the machine will alarm and not work smoothly. This affects...
