The composite nano-silver pet deodorizing disinfectant is used for jointly disinfecting various plant extracts such as nano-silver, yucca extract, fendortin, cornflower extract and the like; on the premise of ensuring the disinfection capability, disinfectants with irritation and potential toxicity, such as quaternary ammonium salt compounds, phenolic compounds and the like, are not used, so that the health of pets and human bodies is ensured. The preparation method disclosed by the invention is simple in steps, mild in conditions and suitable for large-scale production.
Description
Technical Field
The invention relates to the technical field of pet detergents, in particular to a composite nano-silver pet deodorizing disinfectant and a preparation method thereof.
Background
At present, the pet deodorizing disinfectant comprises four active ingredients: cationic surfactant quaternary ammonium salt compound, phenolic compound, plant extract, compound biological enzyme, etc.
Wherein the cationic surfactant such as quaternary ammonium salt compound can kill most kinds of bacteria, fungi and partial viruses, but can not kill spore, tubercle bacillus and pseudomonas aeruginosa; has strong effect on gram-positive bacteria. The components have rapid action, small irritation, low toxicity and no corrosion to metal and rubber; however, the sterilization effect is greatly affected by organic substances.
Phenolic compounds such as Parachlorometaxylenol (PCMX) have killing effects on most gram-positive and gram-negative bacteria, fungi and mould; compared with the traditional phenolic compounds, the compound has low toxicity and small irritation, has good killing effect on common bacterial propagules and fungi, and has strong stability; there is still a potential toxicity of phenolic compounds to organisms and there is a continuing search.
The plant extract such as tea tree essential oil has certain inhibiting effect on bacteria and viruses, and also has anthelmintic effect, and although the side effects such as irritation and potential toxicity are the minimum of the four types, the bactericidal capability is weak and can only be used as an auxiliary.
The compound biological enzyme adopts photosynthetic bacteria, lactobacillus, yeast and other microorganisms, and utilizes the biochemical characteristics of the metabolic process to decompose substances with unpleasant odor, such as pentanethiol, phenylmethylmercaptan, methyl sulfide, ethanethiol, hydrogen sulfide, sulfur dioxide, p-phenylmethylmercaptan, ammonia, dimethylamine, trimethylamine, carbon disulfide and the like; thereby achieving the effect of deodorization.
Most of the deodorizing and disinfecting agents for pets used at present are compound formulas of one or more types of disinfecting agents such as quaternary ammonium salt compounds, phenolic compounds, plant extract components, compound biological enzymes and the like, so that the mutually complementary effect is achieved. But the defects of various components cannot be effectively overcome at present. For example, although the compound formula of tea tree essential oil and compound biological enzyme can simultaneously achieve the effects of sterilization and deodorization, the space for the progress is still large.
Disclosure of Invention
The invention aims to provide a composite nano-silver pet deodorizing disinfectant, which can reduce the irritation to pets as much as possible on the premise of ensuring the disinfecting capability.
The second purpose of the invention is to provide a preparation method of the composite nano silver pet deodorizing disinfectant.
The first purpose of the invention is realized by the following technical scheme:
a composite nano silver deodorizing disinfectant for pets comprises the following components:
furthermore, the water-based paint also comprises solvent water, and the balance is water.
Further, the yucca extract is an aqueous extract of yucca plants.
The preparation method of the yucca extract comprises soaking yucca plants in water, and distilling, chromatographing, and filtering with a filter membrane; obtaining the yucca extract.
Further, the fendorin is fendorin from cypress or/and pinus massoniana.
Further, the cornflower extract is an aqueous extract of a plant of the cornflower genus.
The preparation method of cornflower extract comprises soaking Yucca plant in water, distilling the water in the soaking solution, performing chromatography, and filtering with membrane; obtaining the cornflower extract.
Further, the pH regulator is citric acid and/or sodium citrate.
The second purpose of the invention is realized by the following technical scheme:
a preparation method of a composite nano-silver pet deodorizing disinfectant comprises the following steps:
(1) taking a solvent, adding yucca extract, fendorine and cornflower extract, and completely dissolving the yucca extract, the fendorine and the cornflower extract to obtain a solution A;
(2) adding nano silver into a solvent to obtain a nano silver solution;
(3) adding the solution A into the nano silver solution, and adding a pH regulator to ensure that the pH value of the solution is 6.5-7.5.
Further, the solution A is subjected to a decoloring treatment before being poured into the nano-silver solution.
The nano silver is a main effective component playing a role in disinfection, and the nano silver can be combined with sulfydryl (-SH) on bacterial protease to make the protease lose activity and cause bacterial death. When the bacteria die and are lysed, the silver is in a free state again and contacts other thalli again, so that the silver has a relatively long-lasting bactericidal effect. Meanwhile, compared with other traditional bactericides such as hypochlorous acid, quaternary ammonium salt and the like, the unique bactericidal mechanism of the nano-silver has the advantages of wide bactericidal range, small irritation and low toxicity. It is possible to kill the odor-causing pathogens from the source, thereby reducing the generation of odor.
The main active ingredients in the yucca extract are saponin, yucca phenol and polysaccharide. The saponin is urease inhibitor, and can inhibit the chemical process of generating ammonia gas from nitrogen-containing substances. Yucca phenols may incorporate amino groups. The polysaccharide can promote microorganisms to synthesize mycoprotein by using ammonia gas, reduce the generation of ammonia gas, increase the consumption and utilization of ammonia gas and reduce the ammonia content.
The phytoncide used in the invention is extracted from cypress and pinus massoniana; phytoncin (terpen) is an aromatic hydrocarbon released after plant injury: mainly comprises monoterpene, sesquiterpene and diterpene, and has antibacterial and anthelmintic effects.
The cornflower extract disclosed by the invention is a mild natural skin cleanser, has a certain inhibition effect on melanocytes, and is soft, moist, soothing and elastic.
The invention has the following beneficial effects:
1. the composite nano-silver pet deodorizing disinfectant is used for jointly disinfecting various plant extracts such as nano-silver, yucca extract, fendortin, cornflower extract and the like; on the premise of ensuring the disinfection capability, disinfectants with irritation and potential toxicity, such as quaternary ammonium salt compounds, phenolic compounds and the like, are not used, so that the health of pets and human bodies is ensured.
2. The preparation method disclosed by the invention is simple in steps, mild in conditions and suitable for large-scale production.
