Description

Technical Field

[0001] The present invention belongs to the technical field of air purification, and particularly relates to a plant odor-removing composition, a preparation method thereof, and an application thereof. Background Art

[0002] Odors, usually referring to unpleasant smells, may originate from various pollution sources, such as industrial emissions, domestic waste, sewage treatment, human excreta, etc. Malodorous gases often contain harmful chemical substances such as benzene, toluene, styrene, etc. These substances not only cause strong irritation to people's sense of smell, but more importantly, long-term inhalation or short-term large-dose inhalation may also cause serious harm to human health. For example, they can damage the respiratory, digestive, and nervous systems, causing diseases such as bronchitis, pneumonia, and gastritis, and even increasing the risk of cancer. In addition, odors can adhere to the skin, damage the skin barrier, and cause allergic reactions and skin diseases. Therefore, eliminating odors in the environment, that is, odor removal, is not only a need to improve air quality and enhance living comfort, but also an important measure to protect human health and prevent diseases.

[0003] Currently, there are various methods for deodorization and odor removal on the market. They each have their own characteristics, but there are also some deficiencies. A common method is to use strong oxidants, such as ozone, hydrogen peroxide, etc., to oxidize the fragrance or odor. This method achieves the deodorization effect by destroying the molecular structure of the fragrance and odor. However, strong oxidants may produce harmful by-products during the reaction, causing potential harm to the human body and the environment. In addition, the use conditions of strong oxidants are relatively harsh, requiring specific equipment and operations, which increases the cost and complexity. Another method is to use another suitable fragrance to cover up the unpleasant fragrance for humans or animals, etc., to achieve the deodorization effect. Although this method can cover up the odor to a certain extent, it cannot really remove the root cause of the odor, so the purpose of odor removal cannot be achieved. In addition, long-term fragrance masking may make people feel uncomfortable and even cause new environmental pollution problems. There is also a method to remove the fragrance or odor by encapsulation or adsorption. This method usually uses various adsorbents, such as activated carbon, silica gel, zinc ricinoleate or zinc ricinoleate esters, etc. These adsorbents adsorb odor molecules on the surface or inside through physical or chemical actions, thereby achieving the deodorization effect. However, the adsorption time may be relatively long, and the adsorption effect is greatly affected by factors such as environmental humidity and temperature. In addition, some adsorbents need to use solvents during the dissolution process, and these solvents may cause harm to the human body, so they are not suitable for use on people or animals.

[0004] Compared with the above methods, plant odor purification is a safer and more environmentally friendly way of deodorization. Plant odor purification mainly utilizes the natural components of plant extracts. Through their unique chemical structures and biological activities, they react with or adsorb odor molecules, thereby achieving the effect of deodorization and odor purification. The plant odor purification method has many advantages: First, plant extracts are derived from natural plants, non-toxic and harmless, and friendly to humans and the environment. They do not produce harmful by-products during use and do not cause harm to the human body. Second, the plant odor purification method has wide applicability. Due to the diverse chemical structures and biological activities of plant extracts, they can be customized for different odor sources to achieve more precise deodorization effects. In addition, the plant odor purification method also has durability and economy. Compared with strong oxidants or adsorbents, plant extracts usually have a longer service life and lower maintenance costs. They can not only effectively remove odors, but also improve air quality and enhance people's quality of life.

[0005] In view of the various deficiencies of the existing deodorization and odor purification methods, it is of great significance to research and develop a plant odor purification composition. This composition can make full use of the natural advantages of plant extracts to achieve safe, environmentally friendly and efficient deodorization and odor purification effects. It can be widely applied to indoor environments such as homes, offices, and public places, and can also be used in fields such as automobiles and pet supplies, providing people with a healthier and more comfortable living environment. At the same time, the research and development of plant odor purification compositions also helps to promote the development of the environmental protection industry, promote resource conservation and environmental sustainable development.

[0006] In summary, researching and developing a plant odor purification composition is an effective way to solve the deficiencies of existing deodorization and odor purification methods, and has important practical application value and significance. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the present invention aims to provide a plant odor purification composition, its preparation method and application. Based on the fact that under high-temperature conditions, oils and fats will undergo saponification reactions under the action of strong alkalis, and during the saponification process, the complexation of flavonoid components with zinc ions to form flavonoid-zinc complexes has broad application prospects in the field of deodorization and odor purification.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0014] S2. Add the formulated amounts of zinc gluconate and potassium hydroxide into 8-10 parts of water, fully dissolve them, and immediately pour them into the mixed reaction solution described in step S1. Stir well until the content becomes solid, stop stirring, and keep it at a constant temperature of 80-90 °C until the solid content is completely transparent to obtain a solid content;

[0015] S3. Boil the remaining water, add the formulated amount of sodium bicarbonate into the boiling water, fully dissolve it, add it to the solid content in step S2, add the formulated amount of alkyl polyglycoside after complete dissolution, stir evenly, cool to 50-60 °C, and adjust the pH value to 7-10 to obtain a plant odor-removing composition.

[0016] Preferably, the stirring speed in step S2 is 50-100 revolutions per minute.

[0017] Preferably, the constant temperature time in step S2 is 1-3 hours.

[0018] Another object of the present invention is to provide an application of a plant odor-removing composition as described above in the preparation of body odor removers for humans and pets.

[0019] The design principle and idea of the present invention:

[0020] Flavonoid components are a type of polyphenolic substances based on the C6-C3-C6 structure, including various types such as flavones, flavonols, biflavonoids, isoflavones, dihydroflavones, dihydroflavonols, chalcones, aurones, anthocyanins, and flavans. They are widely present in plants, possess various physiological functions such as antioxidant and anti-cancer effects, mostly exist in the form of glycosides, are the active ingredients of many Chinese herbal medicines, and have extensive application values in the fields of medicine, food, and health products.

[0021] First of all, the present invention provides a plant odor-removing composition, and its components include compounds such as grape seed oil, sunflower seed oil, coconut oil, bitter almond oil, olive extract, safflower extract, etc. Among them: (1) Grape seed oil is rich in linoleic acid, oleic acid, saturated fatty acids, and fat concomitants such as flavonoids, polyphenols (proanthocyanidins), catechins, vitamin E, and lecithin. (2) Sunflower seed oil mainly contains components such as linoleic acid, oleic acid, vitamin E, and phytosterols. (3) When coconut oil is used as food, its main components include saturated fatty acids, lauric acid, myristic acid, palmitic acid, etc.; when used as an external product, it may also contain other chemical components such as glycerol and vitamins. (4) Bitter almond oil generally refers to benzaldehyde, which is the main component in the extract of bitter almond oil and can also be obtained from apricots, cherries, laurel leaves, and peach kernels. (5) Olive extract is derived from the dried leaves of plants in the genus Olea of the Oleaceae family and mainly contains various components such as flavonoids, terpenoids and their derivatives, aromatic compounds, aliphatic compounds, and phenolic acid compounds. (6) Safflower extract is extracted from the plant safflower and mainly includes active ingredients such as flavonoid compounds, safflower acid, and safflower glycoside. In summary, the plant odor-removing composition of the present invention adds a variety of natural oils and extracts rich in flavonoids.

[0022] The plant odor-removing composition of the present invention also includes components such as zinc gluconate, potassium hydroxide, alkyl glycoside, sodium bicarbonate, and water. As is well known to those skilled in the art, the saponification reaction of oil and strong base is a chemical reaction that breaks the ester bonds in the oil and generates sodium higher fatty acid salt (the main component of soap) and glycerol. This reaction is carried out under higher temperature and stirring conditions, and a co-solvent can be used to improve the reaction efficiency, which is widely used in fields such as soap manufacturing, food processing, and surfactant synthesis. Thus, based on the principle that oil will undergo saponification reaction under the action of strong base, the present invention uses grape seed oil, sunflower seed oil, coconut oil, and bitter almond oil, etc. as the main components of the saponification reaction, and under high temperature conditions, undergoes saponification reaction with potassium hydroxide, and the ester bonds in the oil molecules are broken, generating fatty acid salts and glycerol.

[0023] Secondly, during the saponification reaction, the zinc ions in the zinc gluconate added in the present invention can undergo a complexation reaction with the flavonoid components in natural oils and extracts to form a stable flavonoid-zinc complex. This is because zinc ions have empty orbitals that can accept the electron pairs provided by ligands; while flavonoids have a high degree of delocalization, and the entire molecule forms a large π-bond conjugated system. The oxygen atoms in the flavonoid molecule have strong coordination ability, which makes the spatial structure of the flavonoid nucleus conducive to the formation of complexes. This complexation not only enhances the stability of flavonoid components but may also change their original chemical properties, endowing the complex with the functional property of interacting with odor molecules, adsorbing them on the surface, and thus reducing the concentration of odors. In addition, zinc ions themselves may also undergo a neutralization reaction with odor molecules, further reducing the release of odors.

[0024] Finally, in the preparation system of the plant odor-neutralizing composition of the present invention, alkyl polyglycoside, as a surfactant, can play a role in increasing the deodorizing ability and auxiliary effects by enhancing the adsorption capacity, improving the dispersibility, adjusting the pH value, and synergistically acting with other components; sodium bicarbonate, as a pH regulator, ensures the stability of the system; water is used as a solvent, and finally, the plant odor-neutralizing composition with odor-neutralizing and deodorizing effects of the present invention is prepared.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] First of all, the present invention provides a plant odor-neutralizing composition. By using a variety of plant extracts and through scientific proportioning and chemical reactions, it realizes the efficient adsorption and decomposition of odor molecules, thus significantly improving the odor-neutralizing and deodorizing effects. Moreover, the present invention uses a variety of natural plant extraction components, which are non-toxic and harmless, do not contain any chemical additives, and will not cause negative impacts on human health or the environment during use.

[0027] The plant odor-neutralizing composition of the present invention is applicable to a variety of scenarios, such as homes, offices, the interior of cars, pet areas, etc., and can effectively remove various sources of odors, such as food residues, tobacco, sweat, pet body odors, etc., and has wide applicability.
