Description

Deodorant with antibacterial effect

Technical Field

The present application relates to the field of deodorization, and more particularly, to a deodorant having antibacterial effect.

Background

As the industry chain for pet feeding has been expanding, the hygiene problem in the pet feeding process has become more serious. In the raising process, the pet excretes uncontrollably, likes to lick the surfaces of household objects, brings pathogenic bacteria into living environment after going out, and the like, so that the odor in the living environment is serious, and the pathogenic bacteria on the surfaces of the objects are high in content. Therefore, it is necessary to perform a sterilization and deodorization process for living environments.

The treatment is usually carried out by adopting a medicament with the disinfection and deodorization effects. In the related art, the preparation with the disinfection and deodorization effects is generally chlorine dioxide, chinese herbal medicine extract and the like. Chlorine-containing disinfectants such as chlorine dioxide have excellent sterilizing effect, but the chlorine-containing disinfectants have high requirements on dosage use precision and have corrosion effect on metal products. Chlorine-containing disinfectants are not suitable for disinfection in environments such as ordinary houses.

The Chinese herbal medicine extract generally comprises materials such as mugwort leaf, pricklyash peel, shaddock peel, chlorophytum comosum, tiger tail orchid, tea polyphenol, grape seed and the like, and is often compounded with porous loose materials such as active carbon and the like for use, but the deodorant compounded by the materials is found after actual use detection: the deodorant containing the Chinese herbal medicine extract is sprayed on pollution sources such as pet excreta/saliva/urine, and the like, and after standing for 10min, the odor of the pet excreta/urine can still be perceived, and the deodorizing effect still needs to be improved. The method is characterized in that a small amount of pollution sources treated by the Chinese herbal medicine extract are taken for sterilization effect detection, and the applicant finds that the Chinese herbal medicine extract has poor sterilization effect, and the sterilization logarithmic value is only 0.88 and can not meet the standard of being used as a disinfectant because the pollution sources formed by pet excreta/saliva/urine have extremely high bacteria content.

In view of the above-mentioned drawbacks of the related art, there is a need for a treatment agent that can perform a high-efficiency and durable antibacterial deodorizing function.

Disclosure of Invention

Preferably, the photocatalyst is formed by blending nano titanium dioxide and nano zinc oxide according to the weight ratio of (1-3): 1.

By adopting the technical scheme, the photocatalyst is screened, and the nano titanium dioxide and the nano zinc oxide are found to have a synergistic effect in bacteriostasis and deodorization; the nano titanium dioxide overcomes the defect of poor light stabilization effect of the nano zinc oxide, and the nano zinc oxide improves the problem that the photocatalysis of the nano titanium dioxide to hydrogen peroxide is weak, so that the hydrogen peroxide can be maintained long.

Optionally, the component B also comprises a compound plant extract, wherein the concentration of the compound plant extract is 20-46g/L.

Preferably, the plant of the compound plant extract is at least three of mugwort, asparagus, bract, small golden plum, saururus chinensis and Bai Zhili olive.

By adopting the technical scheme, various active ingredients contained in the composite plant extract can combine sulfur-containing compounds, nitrogen-containing compounds, and odor molecules such as acetic acid and butyric acid, and can inhibit the decomposition of urease, and the mugwort, asparagus, bract grass, small golden plum, saururus chinensis and Bai Zhili olive have synergistic effect in deodorization.

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

By adopting the technical scheme, the pet smell is sensitive, the characteristic smell of the D-limonene can be smelled, and the pet is annoyed to the characteristic flavor emitted by the D-limonene, so that the pet can be prevented from licking the sprayed deodorant, and the antibacterial and deodorizing effects of the deodorant are prolonged from the physical aspect.

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

By adopting the technical scheme, the combination capability of the rhizoma cibotii 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 10-26g/L.

Optionally, the surfactant is at least two selected from fatty alcohol methacrylate, magnesium dodecyl sulfate, soybean ethyl sulfate morpholine, octadecyl amine polyoxyethylene ether biquaternary ammonium salt, high molecular cation alkyl polyglucoside and cetyl alcohol polyoxyethylene ether dimethyl octyl ammonium chloride.

By adopting the technical scheme, the surfactant and the hydrogen peroxide have synergistic effect in sterilization and deodorization. The surfactant can enable the photocatalyst to be fully dispersed in the component B, and is favorable for uniform spraying of the photocatalyst when the deodorant is used, so that the photocatalyst has better catalytic effect on hydrogen peroxide. Any two of the surfactants have good sterilization effect.

In summary, the present application has at least the following beneficial effects:

1. the hydrogen peroxide, protocatechuic acid, the photocatalyst, the dopamine, the zinc ricinoleate and other substances are used together, so that the sterilizing and deodorizing effects on pollution sources such as pet excreta/saliva are excellent, and the long-term antibacterial and deodorizing functions can be achieved.

2. The deodorant is also added with composite plant extracts, and the compound use of various plants such as locust legs, asparagus, bracts, herba patriniae, exendin, bai Zhili elets and the like can effectively improve the deodorizing effect of the deodorant.

3. A small amount of D-limonene is added into the deodorant, and the characteristic flavor of the D-limonene is unpleasant to pets such as cats and dogs, so that the pet can be effectively prevented from licking the deodorant, and the antibacterial deodorizing effect of the deodorant is prolonged from the physical aspect.

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

Note that: "/" indicates that the deodorant has no bactericidal effect at all.

TABLE 5 sensory evaluation score after deodorant treatment of contamination source

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 restored to room temperature without obvious change before an experiment; the deodorant is cooled to-5 ℃ and kept for 24 hours, and then is recovered to room temperature without obvious change before experiments.

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

As can be seen from the combination of example 1 and comparative examples 1 to 3 and tables 3 to 5, in comparative example 1, only a higher concentration hydrogen peroxide solution was used, and although the initial sterilization effect reached the standard, the sterilization was not complete, and bacteria in the contamination source sample grew rapidly within 48 hours. And the deodorizing effect of comparative example 1 was not good, and the odor of saliva/excrement/urine of the pet could still be perceived after spraying.

The comparative example 2 lacks dopamine and the comparative example 3 lacks zinc ricinoleate, both of which have a kill log value which, although being able to reach more than 1.37, is still much lower than that of example 1; meanwhile, the deodorizing sensory evaluation score was also inferior to that of example 1. The following is indicated: the synergistic effect exists between the dopamine and the zinc ricinoleate, hydrogen peroxide can be catalyzed efficiently, 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 effect can be still achieved after 48 h.

And after the deodorant prepared in the example 1 is sprayed, the killing logarithmic value reaches 3.89 after 10 minutes, and the deodorant has remarkable killing effect on coliform and staphylococcus aureus. While the sensory evaluation score for example 1 was as high as 96, it is shown that: the components contained in the A component and the B component have synergistic effect in deodorization.

In comparative example 4, the composite plant extract was used as a sterilization deodorant, and the sterilization logarithmic value after 10min was only 0.88, which could not meet the sterilization standard. Although the deodorizing sensory evaluation score of the composite plant extract reached 48, the odor of saliva/excrement/urine of the pet was slightly felt, and after 48 hours, the deodorizing sensory evaluation score was reduced to 29, indicating that although it had a certain sterilizing deodorizing effect, the sterilizing deodorizing effect was not durable.

The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
