Description

Technical Field

[0001] The present invention relates to the technical field of deodorants, in particular to a reactive deodorant with sterilization and deodorization functions and a preparation method thereof. Background Art

[0002] In daily life, there are always unpleasant odors such as sweat, body odor, feces, and smoke. These unpleasant odors affect people's physical and mental health and reduce their quality of life. With people's attention to fresh air, the removal of these unpleasant odors has become an urgent need for people, making the "deodorization" technology continue to grow and develop. The components of odorous gases mainly include nitrogen compounds such as ammonia, nitrogen oxides, methylamine, etc.; sulfides such as organic sulfur, hydrogen sulfide, mercaptan, etc.; aliphatic compounds such as acetic acid, isovaleric acid, indole, acrolein, skatole, methane, etc. These substances stimulate people's senses, destroy the living environment, and endanger human health. Therefore, it is of great practical significance to carry out research on deodorization technology and eliminate the harm of odor to human health. In addition, with the improvement of people's quality of life and the change of ideas, more and more families begin to keep pets, mostly dogs, cats and other animal pets. While pets bring fun to people, they also cause some troubles, especially the odors produced during the breeding process, such as the fishy smell of oil secreted by sweat glands and the odor of excrement, which not only emit a bad smell, but also contain a variety of harmful substances.

[0003] According to the deodorization mechanism, the deodorizers on the market can be divided into physical deodorizers, chemical deodorizers, biological deodorizers, and plant deodorizers. For example, physical adsorption deodorizers have the disadvantages of short-term deodorization (easy to adsorb saturation), complex process, and easy to produce secondary pollution; physical covering deodorizers have the disadvantages of short-term deodorization and incomplete deodorization. The biggest advantage of microbial deodorizers is that they have a wide treatment range, large load, low cost, non-toxic, long-lasting effect, and will not produce secondary pollution, but they usually cannot produce deodorization effects immediately like chemical deodorizers during use. Plant deodorizers, such as natural plant extracts, are plant deodorizers formed by microemulsification of oils, juices or extracts extracted from trees, flowers and plants in nature and water, but they involve high costs and are not easy to popularize. Therefore, it is necessary to develop deodorization products with good and long-lasting deodorization effects, safety, environmental protection, and low cost to achieve the purpose of improving people's quality of life and purifying the environment.

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, characteristics and effects of a reactive deodorant with bactericidal and deodorizing functions and its preparation method according to the present invention in combination with the preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0037] The following materials or reagents, unless otherwise specified, were commercially available.

[0038] The invention provides a reactive deodorant with sterilization and deodorization functions, which comprises a surfactant, an odor reactant, a deodorization aid, a moisturizer, an emulsifier, a bactericide, a fragrance and deionized water.

[0039] Specifically, the surfactant is one or two of dodecyl ammonium dichloride, hexadecyl trimethyl ammonium bromide, dodecyl ammonia dipropionate, and didecyl quaternary ammonium salt; it increases the volatilization of odor, increases the solubility with other solvents, and regulates the hydrophilicity and hydrophobicity in the reaction system.

[0040] Specifically, the odor reactant is one or two of corn extract, oat starch, lauric acid glyceride, 2-hydroxypropyl β-cyclodextrin, and amino acids in soybeans; it is a key substance for chemically combining with odor molecules. It can deodorize through a bonding mechanism and form strong chemical bonds with nitrogen and sulfur atoms in the odor, thereby completely eliminating the odor.

[0041] Specifically, the deodorizing aid is one, two or three of disodium maleate, citric acid, benzoic acid, diethylene glycol, ethanol and polyamine polymer; it assists in deodorizing, increases the volatility of odor components, and effectively adjusts the buffering properties and acid-base properties of the solution.

[0042] Specifically, the moisturizing agent is one or two of methyl ether polydimethylsiloxane, diethylene glycol, and PPG-11 stearyl ether; it is mainly used as a solvent and can be miscible with other solvents such as water to improve its solubility in fabrics.

[0043] Specifically, the emulsifier is one or two of polyoxyethylene cetyl ether, tetraethylene glycol monolaurate, coconut alcohol, hydrogenated castor oil and coconut glucoside; it improves stability and long-term effectiveness, effectively increases the solubility and dissolution rate of some poorly water-soluble molecules in water, and is used as a stabilizer.

[0044] Specifically, the bactericide is one or two of didecyldimethylammonium chloride and dodecyldimethylbenzylammonium bromide; it plays a role in disinfection and sterilization, and at the same time increases the solubility with other components.

[0045] Specifically, the fragrance is one type or a mixture of two types of water-based or oil-based fragrances, which imparts a specific fragrance to the deodorant.

[0046] Specifically, the ratio of the surfactant, odor reactant, deodorizing aid, moisturizer, emulsifier, bactericide, fragrance, and deionized water is 0.5%-5%: 1%-5%: 1%-8%: 0.1%-0.4%: 1%-4%: 0.1%-0.5%: 1%-2%: 80%-90%. The deodorizing agent obtained within this ratio range has excellent performance, uniform state, transparency, and stability.

[0047] In the solution system obtained by the present invention, each component is in balance with each other, including the mutual solubility of the water phase and the oil phase, the coexistence of anions and cations, the matching and regulation of acid and base, etc. For example, the presence of the deodorizing agent supports the deodorizing performance of the odor reactant, promotes the combination of the odor reactant with the odor molecules, and promotes the volatilization of the product after the reaction.

[0048] The stable existence of fragrances requires emulsifiers and additives to help them dissolve in aqueous and oily solvents.

[0049] After the combination, the deodorizing durability of the deodorant is enhanced, and the antibacterial function of the deodorant is enhanced.

[0050] The present invention also provides a method for preparing a reactive deodorant having a sterilizing and deodorizing function, comprising the following steps:

[0051] 1) Mix deionized water, a deodorizing agent 1, and a moisturizing agent to obtain a mixture 1; a uniform and stable water-oil solution system is obtained by mixing these solvents.

[0052] 2) Heat the mixture to a temperature of 40-80°C, stir continuously for 5-60 minutes at a stirring speed of 200r / min-800r / min, and then cool it down to 38-60°C; the purpose of heating up is to better dissolve and mix the raw materials; the purpose of cooling down is to provide the odor reactant with the best reaction state, in which its performance is best.

[0053] 3) Mix the odor reactant, the second deodorizing aid, the bactericide, and the surfactant in sequence, and stir at 38-60° C. for 5-60 minutes to obtain a second mixture; add the main deodorizing ingredients (the odor reactant, the second deodorizing aid, and the bactericide) into the uniform water-oil phase to form an effective deodorizing suspension.

[0054] 4) Mix the emulsifier and fragrance, stir for 10-80 minutes, cool to room temperature, and obtain the deodorant. This step enables the deodorant to have a specific fragrance. Finally, the deodorant suspension is given a certain fragrance. The emulsifier is used to emulsify the fragrance and evenly mix the other components, and finally obtain a uniform and transparent deodorant spray.

[0055] The deodorizing aid helps the odor reactant to perform better deodorizing functions during the reaction process. The existence of the first deodorizing aid is to provide a better dissolving and mixing state for the odor reactant, and the second deodorizing aid is to regulate the acid-base balance, hydrophilicity and hydrophobicity of the solution and to cooperate with the odor reactant to remove odor.
