[0024] 1. Bactericidal experiment of bromochlorohydantoin disinfectant:

[0025] The bromochlorhydantoin disinfectant of each formula of above embodiment 1~7 is mixed with the solution of each effective bromine concentration, according to the requirement on the disinfection technical specification (2002 edition) of Ministry of Public Health, carries out the suspension quantification of Bacillus subtilis var. niger spore Bactericidal test, the concentration of the bacterial suspension is 1.3×10 8 cfu / mL. As can be known from Table 2, the disinfectant effect of the embodiment 7 formula of effective bromine 100mg / L can meet the requirements on the disinfection technical specification for half an hour, and it is 2000mg than the concentration of killing spores of the disinfectant that only has bromide chlorhydantoin / L is much lower.

[0026] The minimum concentration of killing spores of the bromochlorohydantoin disinfectant of each formula of table 2

Abstract

The invention discloses stable bromochlorohydantoin disinfection liquid. The stable bromochlorohydantoin disinfection liquid comprises the following components in parts by weight: 1-20 parts of bromochlorohydantoin, 0.1-15 parts of a cosolvent, 1-10 parts of a stabilizing agent, 0.1-2 parts of a synergist, 1-5 parts of a pH regulating agent and 50-90 parts of water. The stable bromochlorohydantoin disinfection liquid has the beneficial effects that the stability is far superior to the use effects of similar disinfectants in the current market, the reduction of the effective concentration of the disinfection liquid is smaller than 10% after the disinfection liquid is put into a drying oven with temperature of 54 DEG C to be preserved for 14 days, and thus the disinfection liquid can meet the stability requirement of Ministry of Health on the disinfection liquid; a surface disinfection effect is enhanced; for achieving the preferable surface disinfection effect, the synergist is added to reduce the surface tension of the disinfection liquid to be below 40 dyne / cm, so that the disinfection liquid can well wet the surfaces of microorganisms to achieve the synergistic effect.

Description

technical field [0001] The invention relates to the field of disinfection, in particular to a stable bromochlorohydantoin disinfectant. Background technique [0002] Bromochlorohydantoin is a new type of release-type disinfectant, which has a good bactericidal effect because it can release active ingredients. The available bromine in bromochlorohydantoin is the main component for killing microorganisms. In aqueous solution, bromochlorohydantoin can react with water to generate hypobromous acid and free bromine. Hypobromous acid and free bromine have strong oxidizing properties, which can oxidize and decompose the biological enzymes in microorganisms to make them invalid, thereby achieving the effect of eliminating microorganisms. Hypobromous acid and free bromine can also react with nitrogen-containing compounds to form ammonium bromide, which still has a certain bactericidal effect. As a carrier, 5,5-dimethylhydantoin can be decomposed into nitrogen and carbon dioxide in ...
