Abstract

The invention relates to compound o-phthalaldehyde disinfection concentrated liquid, belonging to the technical field of disinfection. The disinfection concentrated liquid is prepared from the following components (by weight percent): 1-5% of o-phthalaldehyde, 2-15% of double-chain behenyl trimethyl ammonium chloride, 5-10% of a nonionic surfactant, 10-30% of fatty alcohol, 2-5% of a penetrating agent, 0.1-2% of a chelating agent, 0.5-3% of a corrosion inhibitor, 0.05-6% of organic acid and the balance being water. The disinfection concentrated liquid is broad in spectrum, efficient, low in toxicity, free of a pungent smell, stable in performance, low in corrosivity on metal, and especially applicable to disinfection of agricultural and breeding articles and environment, and can be diluted into 4,000 times to the maximal extent.

Description

technical field [0001] The invention relates to a compound o-phthalaldehyde disinfection concentrate, in particular to a disinfection concentrate containing o-phthalaldehyde and a double-chain quaternary ammonium salt, belonging to the technical field of disinfection. Background technique [0002] Although there are many high-efficiency disinfectant concentrates on the market, each of them has certain disadvantages. For example, aldehydes (formaldehyde, glutaraldehyde) have certain toxicity and irritation, and the disinfection effect and stability are greatly affected by pH. , Corrosive to metals; peroxides have poor stability and strong corrosiveness; chlorine-based disinfectant concentrates are highly corrosive and irritating, therefore, it brings a lot of inconvenience to the disinfection of the aquaculture industry and other industries. [0003] O-phthalaldehyde (English name O-Phtnalaldehyde; English abbreviation OPA) is a high-efficiency disinfectant developed by weste...
