Description
Technical field
The present invention relates to chemosterilant, particularly a kind of compound ortho-phthalaldehyde polyquaternium cationic surfactant disinfectant and preparation and application thereof.
Background technology
At present disinfection product main component has aldehydes, Operand, compound phenol, chlorinated product, quaternary ammonium salt etc., and wherein aldehyde product is mainly glutaraldehyde and formaldehyde goods, and the product take o-phthalaldehyde(OPA) and polyquaternium as major constituent is not yet arranged.o-phthalaldehyde(OPA) (O-phthalaldehyde, OPA) finished product is a kind of flaxen acicular crystal, can be water-soluble, also be dissolvable in water the organic solvents such as pure and mild ether, it is a kind of wide spectrum, efficiently, the new disinfectant of low-corrosiveness, see the earliest (the Alfa MJ such as Alfa in 1994, Sitter DL.In hospital evalution of orthophthalaldehyde as a high level disinfectant for flexible endoscopes[J] .J Hosp Infect, 1994, (26): report 15.), used by drugs approved by FDA in 1999.The research o-phthalaldehyde(OPA) is to intend replacing glutaraldehyde as the original intention of disinfectant, because the bactericidal effect of o-phthalaldehyde(OPA) is better than glutaraldehyde (Rutala WA, Weber DJ.New disinfction and sterilization methods[J] .Emerging infectious diseases, 2001,7 (2): 348.).research is found, the pH value of antiseptic solution has very significantly impact to Germicidal Efficacy of Orthophthalaldehyde, stronger (the Walsh SE of the bactericidal effect of o-phthalaldehyde(OPA) under alkali condition, Maillard JY, Russell AD.Ortho-phthalaldehyde:a possible alternative to glutaradehyde for high level disinfection[J] .Applied Microbiology, 1999, 86 (6): 1039), but the researchs such as Xu Nengfeng find that also its bactericidal effect descends on the contrary when pH surpasses 9.0, optimum pH value is that 7.5～8.5(is permitted the energy cutting edge of a knife or a sword, stand in great numbers prosperous, Xu Wenti, Deng. o-phthalaldehyde(OPA) is killed the extremely research of influence factor of bacillus subtilis black variety gemma effect. Chinese Disinfection magazine, 2005, 22 (2): 125.).Single o-phthalaldehyde(OPA) kill bacteria gemma needs the time long, need to improve its dissipation ability and speed by formula.And the concentration meeting decrease to some degree when reusing of single o-phthalaldehyde(OPA), this has also affected disinfection effect.Once had the composite report of o-phthalaldehyde(OPA) and little molecule quaternary ammonium salt (woods grand plan etc., the development of quaternary ammonium salt complex phthalic aldehyde disinfectant, Chemical Industry in Guangzhou, 2008,36(4): 40-41; Zuo Zhiwen etc., the research of o-phthalaldehyde(OPA) and the effect of Domiphen bromide Synergistic biocidal, Shandong medicine thing, 2008,27(4): 245-249), but little molecule quaternary ammonium salt toxicity is stronger and unstable.The quaternary ammonium salt of aggretion type is as polymer composite, and the functional group that has kept quaternary ammonium salt is active and reduced its toxicity, the also corresponding raising of its degree of stability in the aqueous solution.And single polyquaternium only is the low elimination agent of killing activity, adopt the polyquaternium cationic surfactant to add to allocate the o-phthalaldehyde(OPA) antiseptic solution as compound synergic reagent, make it still keep very fast dissipation speed when the O-phthalic aldehyde concentration descends, yet there are no any report.
