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
The present invention relates to a kind of compound ortho-phthalaldehyde sterilization concentrate, be specifically related to a kind of sterilization concentrate that contains o-phthalaldehyde(OPA) and double-chain quaternary ammonium salt, belong to disinfection technology field.
Background technology
Although there is in the market the sterilization concentrate of a lot of high-effective disinfecting levels, all there is separately certain drawback, as aldehydes (formaldehyde, glutaraldehyde) has certain toxicity, excitant, it is larger that Disinfection Effect and stability are affected by pH, and metal is corrosive; Peroxide poor stability, corrosivity are strong; Chloro sterilization concentrate corrosivity is strong, excitant is large, therefore, brings inconvenience to the sterilization of cultivation industry and other industry.
O-phthalaldehyde(OPA) (English name O-Phtnalaldehyde; English abbreviation OPA) be a kind of high-efficiency sterilizing and disinfecting agent that last century, the nineties western countries developed, there is the advantages such as efficient, quick, toxicity is low, excitant is little, overcome the shortcomings that traditional high-effective disinfecting concentrate exists, become very popular Novel sterilizing product, and obtain U.S. FDA approval use.
Double-chain quaternary ammonium salt contains a hydrophilic group and two lipophilic groups conventionally, has that bactericidal effect is good, concentration is low, an advantage such as easy to use, stable in properties, heat-resisting, fast light, resistance to storage, can kill various microorganisms, bacterial spore, belongs to high-effective disinfecting concentrate.
But single o-phthalaldehyde(OPA) sterilization concentrate or its Disinfection Effect of double-chain quaternary ammonium salt sterilization concentrate are undesirable, particularly under low concentration, (dilute 2000 times or higher), almost there is no bactericidal effect.
In sum, be badly in need of at present a kind of wide spectrum of research, efficient, stable performance, excitant is little, toxicity is low, sterilization concentrate that can high dilution.
Summary of the invention
