Description

Composition with deodorizing and antibacterial effects and preparation method and application thereof
Technical Field
The invention relates to a deodorant, in particular to a composition with deodorizing and antibacterial properties and a preparation method thereof.
Background
The air quality of the environment is one of the important factors affecting the health of human bodies and the thought and emotion, the smell of people is very sensitive, the odor can cause breathing disorder of people, headache, nausea, cardiovascular disease, nerve hypofunction and other diseases are induced, the health of people is greatly endangered, and the odor is mainly from places such as garbage transfer stations, garbage cans, garbage depositing points, garbage burning plants, sewage plants and the like in the daily life of people at present.
The deodorant in the market at present has various patterns, mainly comprises chemical deodorant, enzyme product deodorant, plant deodorant, microorganism deodorant and the like, and the first chemical deodorant represented by chlorine dioxide, hypochlorite, ferrous sulfate and the like has the main effects of oxidation sterilization, and the deodorization mechanism mainly comprises desulfurization, oxidation, condensation, addition reaction and the like of odor molecules. The bactericidal products have strong bactericidal effect, eradicate putrefying bacteria, and eradicate the root cause of odor generation, thereby assisting the function of serving as a deodorant, and being capable of treating the root cause. The disadvantage is that people contact the disinfectant closely, are easy to inhale into alveoli, can cause chronic injury, and have poor safety; the microbial deodorant adopts deodorant microorganisms obtained by screening to construct a composite microbial inoculum, has better control effect on malodor sources formed by perishable organic substances, has insignificant effect on deodorization and longer period; the plant deodorant is prepared by compounding an extract of oil, juice or extractum extracted from roots, stems, leaves or flowers of plants according to a certain formula, wherein effective molecules in the plant extract contain active groups such as chemical activity, biological activity, conjugated double bonds and the like, and can react with different peculiar smell substances such as acid-base reaction, catalytic oxidation reaction, lewis acid-base reaction, oxidation-reduction reaction and the like to promote the malodorous substances to change the original molecular structure and decompose into non-toxic and odorless micromolecules, thereby achieving the aim of thoroughly eradicating the odor.
The deodorant in the market has various patterns, and a large amount of deodorant can cover the odor on the pet body or in the environment by the fragrance emitted by the essence, so that the odor problem on the source head, especially the odor caused by biological spoilage and fermentation, can be solved, and the odor can be removed and maintained only for a temporary treatment but not for a permanent treatment. Some plant deodorant is added with natural components such as essential oil or extract obtained from plants, which can cause effect on part of odor molecules, but most of the effective components in the extract are small molecules, and zinc ricinoleate adsorbs odor and simultaneously adsorbs the extract components which should be used for deodorization.
In chinese patent application CN108245449a published at 7 and 6 in 2018, a pet deodorant is disclosed, which contains linalool acetate, citronellol, phenethyl alcohol, parachlorometaxylenol, lauryl methacrylate, linalool extract, polysorbate, citric acid, essence, alcohol, deionized water. The deodorant can be directly sprayed on pets, has remarkable deodorizing effect and long duration, and has sterilizing effect. However, the deodorizing essence added in the deodorizing agent can only cover the smell, and the preparation process is complex, so that the production cost is increased.
A deodorant with antibacterial effect is disclosed in Chinese patent application CN114831137A published at 8/2022. The composition comprises hydrogen peroxide solution with the concentration of 12-18 g/L, protocatechuic acid solution with the concentration of 0.1-2.6 g/L, a photocatalyst with the concentration of 0.01-0.3 g/L, dopamine solution with the concentration of 1.9-5.1 g/L and zinc ricinoleate with the concentration of 2-12 g/L. The deodorant has remarkable sterilizing and deodorizing effects, and can be used for sterilizing and eliminating odor. However, the disinfecting effect of the deodorant is not ensured in terms of safety because of the addition of chemical disinfecting components.
Therefore, development of a composition having an odor-removing and antibacterial effect, which can not only make efficient use of the components of the odor remover for a long period of time, but also sterilize indoor spaces and eradicate putrefying bacteria, has become an urgent need.
