Description

Deodorant with antibacterial effect

Technical Field

The application relates to the field of deodorization, in particular to a deodorant with bacteriostatic effect.

Background

As the industry chain of pet feeding is gradually expanded, the sanitary problem in the pet feeding process is also increasingly serious. In the feeding process, the behaviors that pets excrete uncontrollably, like licking the surfaces of household objects, bringing pathogenic germs into the living environment after going out, and the like, can cause serious peculiar smell in the living environment, and the pathogenic germ content on the surfaces of the objects is high. Therefore, it is necessary to perform a sterilization and deodorization treatment for the residential environment.

The treatment is usually carried out by using a medicament with the effects of disinfection and deodorization. In the related art, the preparations with the disinfection and deodorization effects are generally chlorine dioxide, Chinese herbal medicine extracts and the like. Although chlorine dioxide and other chlorine-containing disinfectants have excellent sterilizing effects, chlorine-containing disinfectants have high requirements on dosage use precision and have corrosive effects on metal products. The chlorine-containing disinfectant is not suitable for disinfection of common houses and other environments.

The Chinese herbal medicine extract generally comprises substances such as folium artemisiae argyi, pepper, shaddock peel, chlorophytum comosum, sansevieria trifasciata, tea polyphenol, grape seeds and the like, and the Chinese herbal medicine extract is often compounded with porous loose materials such as active carbon and the like for use, but the deodorant compounded by the substances is found after actual use and detection: the deodorant containing Chinese herbal medicine extract can be sprayed on pet excrement/saliva/urine and other pollution sources, still can feel the odor of pet saliva/excrement/urine after standing for 10min, and the deodorizing effect still needs to be improved. A small amount of pollution sources treated by the Chinese herbal medicine extract are taken for carrying out sterilization effect detection, the applicant finds that the sterilization effect of the Chinese herbal medicine extract is poor, the sterilization log value is only 0.88 due to extremely high bacteria content of the pollution sources formed by pet excrement/saliva/urine, and the standard of using the pollution sources as a disinfectant cannot be met.

In view of the above-mentioned drawbacks of the related art, there is a need for a treating agent with high-efficiency and durable antibacterial and deodorant effects.

Disclosure of Invention

meanwhile, the oxygen released by the hydrogen peroxide promotes dopamine to form aggregates under the acid/alkaline environment through covalent bonds, so that the enrichment film is formed on the surfaces of pet excrement/pet saliva and other pollution sources, the film covers the pollution sources, odor emission is blocked, partial oxygen is adsorbed, and the escape of strong oxygen free radicals is reduced, so that the sterilization and deodorization efficiency is improved, and the sterilization and deodorization efficiency in a short time (less than or equal to 10min) is realized;

the polymer film obtained by enriching dopamine has good stability and can be coated on the surface of a pollution source for a long time; the zinc ricinoleate can be continuously activated in a humid environment generated by the decomposition of hydrogen peroxide, and activated zinc atoms are combined with odor molecules through hydrogen bonds and covalent bonds, so that the antibacterial and deodorant effects are prolonged; protocatechuic acid can inhibit the proliferation of harmful bacteria in pollution sources such as streptococcus, fungi and the like, can also reduce the possibility of generating ammonia gas, hydrogen sulfide and indole, and also can inhibit the activity of urease; therefore, the deodorant can play a long-acting antibacterial and deodorizing role.

Optionally, the component B also comprises D-limonene, and the concentration of the D-limonene is 0.1-0.81 g/L.

By adopting the technical scheme, the pet smells sensitively, can smell the characteristic smell of D-limonene, and the pet can smell the characteristic flavor given off by the D-limonene, so that the pet can be prevented from licking the sprayed deodorant, and the bacteriostatic and deodorant effects of the deodorant are prolonged on a physical level.

Optionally, the component A also comprises rhizoma Cibotii polysaccharide, and the concentration of the rhizoma Cibotii polysaccharide is 0.57-1.43 g/L.

By adopting the technical scheme, the binding capacity of the cibotium barometz polysaccharide and amine odor molecules is excellent, and the concentration of odor in a feeding environment can be further effectively reduced.

Optionally, the component B also comprises a surfactant, and the concentration of the surfactant is 10-26 g/L.

Optionally, the surfactant is selected from at least two of methacrylic acid fatty alcohol, lauryl magnesium sulfate, soya ethyl sulfate morpholine, octadecyl amine polyoxyethylene ether biquaternary ammonium salt, high molecular cation alkyl polyglycoside, and cetyl alcohol polyoxyethylene ether dimethyl octane ammonium chloride.

By adopting the technical scheme, the surfactant and the hydrogen peroxide have synergistic effect in sterilization and deodorization. The surfactant can fully disperse the photocatalyst in the component B, and is beneficial to uniformly spraying the photocatalyst when the deodorant is used, so that the photocatalyst has better catalytic effect on the hydrogen peroxide. Any two combinations of the surfactants have good bactericidal efficacy.

TABLE 4 detection results of microbiological indicator 48h after deodorant treatment of pollution source

Note: "/" indicates that the deodorant was completely non-germicidal.

TABLE 5 sensory evaluation scores after deodorant treatment of pollution sources

According to the deodorant stability detection method described in QB-T4524-2013, after the deodorant is heated to 40 ℃ and kept for 24 hours, the deodorant is recovered to room temperature and has no obvious change before the experiment; after the deodorant is cooled to-5 ℃ and kept for 24h, the deodorant is restored to the room temperature and has no obvious change before the experiment.

According to the corrosion detection method of the disinfectant technical specification, the deodorant prepared by the application has almost no corrosion to metal materials such as carbon steel through detection.

By combining the example 1 and the comparative examples 1 to 3 and combining the tables 3 to 5, the comparative example 1 only uses the hydrogen peroxide solution with higher concentration, although the initial sterilization effect reaches the standard, the sterilization is not complete, and the bacteria in the pollution source sample grow rapidly within 48 hours. And the deodorizing effect of comparative example 1 was not good, and the odor of saliva/excrement/urine of pets was still sensed after spraying.

The killing logarithm value of the dopamine in the comparative example 2 and the killing logarithm value of the zinc ricinoleate in the comparative example 3 are both far lower than that of the embodiment 1 although the killing logarithm values can reach more than 1.37; also, the deodorizing sensory evaluation score was inferior to that of example 1. Shows that: the synergistic effect exists between the dopamine and the zinc ricinoleate, the hydrogen peroxide can be efficiently catalyzed, the sterilization rate and the deodorization efficiency within 10min can be improved, the sterilization and deodorization time can be prolonged, and the good deodorization and sterilization effects can still be achieved after 48 hours.

After the deodorant prepared in the embodiment 1 is sprayed, the killing logarithm value is up to 3.89 after 10min, and the killing effect of the deodorant on coliform bacteria and staphylococcus aureus is obvious. While the sensory evaluation score of example 1 was as high as 96, indicating that: the components contained in the component A and the component B have a synergistic effect on deodorization.

In the comparative example 4, the composite plant extract is used as the sterilization deodorant, and the killing logarithm value is only 0.88 after 10min, so that the sterilization standard can not be met. Although the sensory evaluation score of deodorization of the compound plant extract reaches 48, the odor of saliva/excrement/urine of the pet can be still slightly sensed, and after 48 hours, the sensory evaluation score of deodorization is reduced to 29, which shows that although the sensory evaluation score of deodorization has a certain sterilization and deodorization effect, the sterilization and deodorization effect is not lasting.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
