Description

Technical Field

[0001] This invention relates to the field of odor-eliminating products, and more specifically to an odor-eliminating composition and its application. Background Technology

[0002] Unpleasant odors of the scalp or body are a long-standing problem in daily life. For example, the odor produced during hair perming and dyeing involves the reaction of chemicals with hair proteins, with thiol compounds being the primary source. These compounds also react with keratin in the hair under alkaline conditions, producing a pungent, sulfur-like smell. Furthermore, metabolic substances secreted by sweat glands on the scalp or body, such as urea and amino acids, can be decomposed by bacteria like Staphylococcus aureus, producing ammonia and propionic acid, resulting in volatile substances with an ammonia odor. In addition, ammonia can disrupt the skin's pH balance, further exacerbating the odor. Moreover, different odors can compound each other, creating a vicious cycle. Currently, most products on the market mask odors by adding fragrances, which only physically cover the smell and have limited effectiveness.

[0003] Most esters found in nature are ethanol esters of straight-chain carboxylic acids, which are important fragrance components. Many of these lower fatty acid esters impart the top notes of fragrances. In addition to straight-chain esters, some branched esters and unsaturated esters are also important fragrance substances, and they have wide applications in cosmetics, daily necessities, and other fields.

[0004] Chinese invention patent application CN110179705A discloses a bactericidal and odor-removing perfume, composed of fragrance, isopropyl myristate, benzoin, oak extract, etc. This perfume can kill bacteria, thereby improving the generation of secondary odors caused by bacterial decomposition, while also releasing the fragrance of the esters themselves, solving the problem that traditional perfumes only mask odors and other unpleasant smells. However, it still cannot remove thiol compounds and ammonia substances produced by direct skin metabolism, failing to achieve a "multi-faceted" odor removal effect.

[0005] Therefore, further research is still needed on deodorizing ingredients to achieve comprehensive deodorizing effects through compound formulation. In other words, while physically masking odors, we must also consider how to inhibit or remove metabolites produced by skin metabolism and the odor substances produced by the decomposition of these metabolites by bacteria. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composition with a simple formulation and better odor elimination effect, as well as its application.

[0007] This invention is achieved through the following technical solutions:

[0008] The first aspect of the present invention provides a composition for eliminating odors, comprising an α,β-unsaturated carboxylic acid ester and a metal salt, wherein the metal salt comprises at least zinc pyrrolidone carboxylate and zinc ricinoleate; wherein the mass ratio of zinc pyrrolidone carboxylate and zinc ricinoleate is 1:2-5.

[0009] In one embodiment of the present invention, the metal salt further includes component A, which is at least one of zinc chloride, zinc gluconate, zinc lactate, zinc maleate, zinc salicylate, zinc sulfate, and copper salt.

[0010] In a preferred embodiment of the present invention, the copper salt includes at least one of copper chloride and copper gluconate.

[0012] In one embodiment of the present invention, the α,β-unsaturated carboxylic acid ester is an ester formed by an α,β-unsaturated acid and an alcohol.

[0013] In a preferred embodiment of the present invention, the α,β-unsaturated acid is selected from any one of acrylic acid, methacrylic acid, crotonic acid, methyl crotonic acid, and cinnamic acid.

[0016] In one embodiment of the present invention, the mass ratio of the α,β-unsaturated carboxylic acid ester to the metal salt is 0.5-5:1.

[0017] As one embodiment of the present invention, the composition further includes plant extracts.

[0018] In a preferred embodiment of the present invention, the plant extract includes one or more of green tea extract, lavender extract, lemon extract, peppermint extract, sweet orange extract, and rose extract.

[0019] A second aspect of the present invention provides the use of the above-described composition in the preparation of a product for eliminating odors.

[0020] In one embodiment of the present invention, the odor is generated by ammonia, amines and / or sulfides.

[0021] The beneficial effects of this invention are: This invention utilizes a combination of α,β-unsaturated carboxylic acid esters and metal salts, which significantly enhances the odor-eliminating effect under specific ratios. In particular, the combination of zinc pyrrolidone carboxylate and zinc ricinoleate as metal salts with α,β-unsaturated carboxylic acid esters further significantly improves the odor-eliminating effect. The odor-eliminating composition of this invention not only effectively masks unpleasant odors, but its molecular structure also exhibits excellent adsorption and neutralization capabilities for odor molecules, achieving chemical odor removal.

[0022] The plant extracts, particularly peppermint extract, added in this invention provide a refreshing aroma, while the natural menthol they contain provides an immediate cooling sensation, helping to soothe the skin.

[0023] Furthermore, the composition of the present invention is mild and non-irritating, effectively reducing potential damage to the skin barrier and the risk of allergies. This allows the product to not only effectively deodorize and inhibit bacteria, but also provide a soothing and aromatic experience, meeting consumers' demand for multifunctional all-in-one body care products.

[0034] The deodorizing effect of the composition provided by the present invention was measured by the following method: The immediate deodorization capacity of the samples was evaluated using ammonia, trimethylamine, and methanethiol adsorption methods. The specific procedure was as follows: A certain amount of standard ammonia, trimethylamine, or methanethiol was injected into a sealed container to stabilize its initial concentration at (100±5) ppm. 0.5 g of the sample to be tested was weighed into the container, with a blank control group containing no sample. After sealing, the containers were left to stand at room temperature for 30 minutes. The residual concentrations of ammonia, trimethylamine, or methanethiol were measured using a gas detector, and the removal rates of ammonia, trimethylamine, and methanethiol were calculated.

[0035] Removal rate (%) = (initial gas concentration - residual gas concentration) / initial gas concentration × 100%.

[0036] In the above experiment, each test sample and blank control group were performed in parallel 10 times, and the results are expressed as "mean ± standard deviation".

[0037] Example 1 Weigh each raw material according to the weight proportions in Table 1, mix them evenly at room temperature, and prepare the corresponding composition.

[0039] Test case The ammonia removal experiment was conducted on the composition prepared in this embodiment, and the results are shown in Table 2.

[0040] Table 2. Ammonia removal test results for each composition.

[0041] The trimethylamine removal experiment was performed on the composition prepared in this embodiment, and the results are shown in Table 3.

[0043] The composition prepared in this embodiment was subjected to a methanethiol removal experiment, and the results are shown in Table 4.

[0044] Table 4. Results of methanethiol removal experiments for each composition.

[0045] Statistical analysis of the data in Tables 2, 3, and 4 (using t-tests, with a significance level set at p<0.05) showed that the removal rates of ammonia, trimethylamine, and methanethiol by compositions 1, 2, 3, and 8 were significantly higher than those by compositions 9, 10, 11, 12, 13, and 14 (p<0.01). Simultaneously, the removal rate of composition 1 was significantly higher than that of compositions 4, 5, 6, 7, 15, and 16 (p<0.05). This indicates that the present invention, by combining α,β-unsaturated carboxylic acid esters with metal salts of specific ratios and compositions (zinc pyrrolidone carboxylate and zinc ricinoleate), significantly enhances the elimination of the odors of ammonia, trimethylamine, and methanethiol, demonstrating a significant synergistic effect and achieving unexpected technical results.

This embodiment is not intended to limit the patent scope of the present invention.
