Abstract
The invention discloses a sterilization preservative containing 2-methyl-1, 2-benzisothiazole-3-ketone and zinc pyrithione, belonging to the technical field of preservatives. According to the invention, the mass ratio of 2-methyl-1, 2-benzisothiazole-3-ketone to zinc pyrithione is 1 (0.01-100), and by mixing two preservatives, the antibacterial effect is better and the addition amount is lower than that of any one component used alone under the same concentration. The invention is more beneficial to reducing the cost of the sterilization preservative in the product and simultaneously ensures that the product has more environmental protection.
Description
Technical Field
The invention belongs to the technical field of sterilization preservatives, and particularly relates to a sterilization preservative containing 2-methyl-1, 2-benzisothiazole-3-ketone and zinc pyrithione and application thereof.
Background
Methyl-1, 2-benzisothiazol-3-one (MBIT) is commonly used in antimicrobial formulations, primarily as a preservative for products during in-can storage or storage, such as mud ash, adhesives, latex emulsions, tackifiers, mineral slurries, pigment dispersions, household products, and other aqueous products. And can also be used as a metal cutting fluid preservative for preventing the growth of microorganisms (bacteria and fungi).
Zinc Pyrithione (ZPT) has good inhibition effect on bacteria and fungi, and the inhibition effect on gram-positive bacteria is better than that of gram-negative bacteria. The principle of bacteriostasis is that the bacteria can not obtain nutrition and are finally starved to death by eliminating the ion gradient of the bacteria for obtaining nutrition, so that the Zinc Pyrithione (ZPT) can not be consumed when playing the role of bacteriostasis.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a preservative composition containing methyl-1, 2-benzisothiazole-3-ketone and zinc pyrithione, so as to provide a preservative with good bactericidal effect, low dosage and more environmental protection.
The invention also provides application of the preservative composition containing methyl-1, 2-benzisothiazole-3-ketone and zinc pyrithione in the field of sterilization and mildew prevention.
The technical scheme is as follows: in order to solve the technical problems, the invention provides the following technical scheme:
the bactericidal preservative containing 2-methyl-1, 2-benzisothiazol-3-one and zinc pyrithione comprises 2-methyl-1, 2-benzisothiazol-3-one and zinc pyrithione.
Preferably, the mass ratio of the 2-methyl-1, 2-benzisothiazol-3-one to the zinc pyrithione is 1:0.01 to 1: 100; further, the mass ratio of the 2-methyl-1, 2-benzisothiazole-3-ketone to the zinc pyrithione is 1: (0.5-2).
The application of the bactericidal preservative containing 2-methyl-1, 2-benzisothiazole-3-ketone and zinc pyrithione is in the protection scope of the invention.
The bactericidal preservative can be directly added as a raw drug when being added, or can be added after being mixed by a solvent or a solid carrier, such as water, an organic solvent, a surfactant, paraffin, fiber, a metal carrier and the like.
The bactericidal preservative containing 2-methyl-1, 2-benzisothiazol-3-one and zinc pyrithione can be used in the following industries: industrial water (process water, cleaning water); gas purification (filter element, gas scrubber); water treatment (sewage treatment, seawater treatment, reverse osmosis filtration, RO membrane); a heat exchange device; the paper industry; industrial raw materials (starch, emulsion, dispersion, surfactant, auxiliaries); materials (plastics, special materials); the construction and coating industry (paints, emulsion paints, diatom oozes); adhesives (latex, silicone adhesive, industrial adhesives); the printing industry (printing liquids, inks, printing aids); the daily cosmetics industry (shampoos, body washes, detergents, soaps, laundry detergents, skin care products, cosmetics); an industrial cleaning agent; maintaining the product on the floor; metal working industries (metal working fluids, metal cutting fluids); industrial or mechanical oil (lubricating oil, hydraulic oil); leather treatment and leather product protection; the textile industry; wood and wood processing industries.
When the sterilization preservative is applied to preservation, a product can be directly added at any site in the production process, and the addition mode can be that two components are combined and then added according to a proportion, or the two components are separated at different sites and are separately added according to a proportion, so that the specified proportion and concentration in the product are finally achieved.
Has the advantages that: the invention discloses a composition containing 2-methyl-1, 2-benzisothiazole-3-ketone (MBIT) and Zinc Pyrithione (ZPT), wherein when in use, the mass ratio of the 2-methyl-1, 2-benzisothiazole-3-ketone (MBIT) to the Zinc Pyrithione (ZPT) is 1:0.01 to 1:100, the antibacterial effect is better than that of any one of the components used alone under the same concentration. The combination mode of the invention needs lower adding amount than that of singly using one component, which is more beneficial to controlling the cost of the sterilizing preservative in the product and simultaneously ensures that the product is more environment-friendly.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
the synergy index in the present invention is defined as follows:
synergy index
Synergy index (Si) ═ Ca/CA + Cb/CB
CA: the component A is used alone in a concentration required to achieve a certain antibacterial efficiency.
Ca: the component A and the component B are used cooperatively to reach the concentration of the component A when the same antibacterial efficiency is achieved.
CB: the B component used alone is the concentration required to achieve the same antimicrobial efficiency.
Cb: the component A and the component B are used cooperatively to reach the concentration of the component B when the same antibacterial efficiency is achieved.
Three bacterial suspensions, namely Escherichia coli (ATCC-8739), staphylococcus aureus (ATCC-6538) and pseudomonas aeruginosa (ATCC-9027), are mixed in equal amount to form a bacterial test group, and Aspergillus niger (ATCC-16404) spore suspension and Candida albicans (ATCC-10231) bacterial suspension are mixed in equal amount to form a fungal test group. The bacterial concentration is about 108cfu/ml, and the fungal concentration is about 107 cfu/ml. We record the concentrations (ppm) of two components when bacteria and fungi are reduced by more than or equal to 4log values in 24 hours according to different proportions of the two components of 2-methyl-1, 2-benzisothiazole-3-ketone (MBIT) and Zinc Pyrithione (ZPT), calculate a synergy index, and verify the synergy of the two components. The specific results are as follows:
