Description

Technical Field

[0001] The invention belongs to the technical field of pet deodorization, and more specifically, relates to a deodorizing composition, a deodorizing spray, and a preparation method and application thereof. Background Art

[0002] The secretions and excretions of pets can produce many unpleasant feelings, and in severe cases can even cause health problems for humans or pets. As for the odor of excrement produced by pet dogs and cats, the odor of cats is stronger than that of dogs. In particular, cat urine contains a substance called feline urenic acid. Feline urenic acid itself does not have a strong odor, but as it is excreted in urine and comes into contact with the air, it will be converted into a thiol compound (3-methyl-3-mercapto-1-butanol, MMB), which will then emit a unique odor. Moreover, pet odor is a multi-faceted complex odor, not a single odor, so it requires a variety of effective ingredients to achieve odor removal.

[0003] There are mainly the following types of pet deodorizing products on the market: (1) Plant extract technology, which removes odors by chemically reacting special functional groups with ammonia or hydrogen sulfide. However, feline urea and urea will still produce odors to varying degrees under the continuous action of bacteria, and the indicators do not cure the root cause. (2) Bactericidal technology, which inhibits the continuous production of odors and removes odors by killing bacteria, but urine often already contains odors and has a weak effect on odor removal. (3) Bio-enzyme technology, which eliminates odors from the source by catalytic hydrolysis of target proteins and feline urea, but cannot eliminate odors that have already been generated, and bio-enzymes often need to be under specific conditions to exert their maximum effect; (4) Urea elimination technology, which eliminates urea so that urea cannot produce ammonia to achieve the effect of purifying odors, but cannot eliminate odors such as MMB.

[0004] Patent publication number CN117883359A discloses a pet deodorant, a preparation method and its application, wherein the components include EM bactericide, tea extract, hexadecyltrimethylammonium bromide and soybean ethyl sulfate ethyl morpholine, etc. Although it has deodorizing effects on ammonia, hydrogen sulfide and methyl sulfide, the urea in cat urine will continue to decompose to form ammonia, and the deodorizing effect is still poor. Therefore, how to provide a composition with excellent deodorizing effect on cat urine has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the above existing technical problems, the primary purpose of the present invention is to provide a deodorizing composition, which has an excellent deodorizing effect on cat urine; in addition, it has an excellent sterilization rate for a variety of bacteria.

[0006] The second object of the present invention is to provide a method for preparing the deodorant composition.

[0007] The third object of the present invention is to provide a deodorizing composition for use in deodorizing pets, or in removing ammonia and / or cat urine odor.

[0008] A fourth object of the present invention is to provide a deodorizing spray.

[0009] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0010] The present invention claims protection for a deodorant composition, which comprises, by weight: 0.1-5 parts of a copper ion deodorant, 0.1-3 parts of a urease inhibitor, 0.1-2 parts of a composite biological enzyme, 0.1-3 parts of a stabilizer, 0-2 parts of a bactericide, and 75-99.9 parts of a solvent.

[0011] The inventors have found through research that cat urine mainly contains substances such as creatinine, pheromones, electrolytes, urobilin, inorganic salts, uric acid, urea, bacteria, and feline urenic acid. Among them, creatinine, pheromones, electrolytes, urobilin, and inorganic salts are all soluble in water and have basically no odor, while urea and feline urenic acid will gradually decompose to produce ammonia and 3-methyl-3-mercapto-1-butanol (MMB) under the action of bacteria. Urea and feline urenic acid themselves have no odor, but the products produced are the main source of odor, especially MMB is a highly volatile sulfur-containing compound with an extremely unpleasant taste.

[0012] In the present invention, the copper ion deodorant can, on the one hand, chelate with ammonia and hydrogen sulfide to generate copper ammonia ions and copper sulfur compounds, thereby removing odor; on the other hand, the copper ions can coordinate with the sulfhydryl groups in the thiol compounds, thereby removing the unique smell of cat urine. Furthermore, the urease inhibitor can effectively inhibit the further decomposition of urea to produce ammonia. The composite biological enzyme can produce protein that decomposes feline urea, preventing the protein in urine from further decomposing to produce MMB.

[0013] The inventors have found through research that the above copper ion deodorant, urease inhibitor and composite biological enzyme, in combination with other components in the system, have an excellent synergistic removal effect on the odor of cat urine and ammonia; in addition, they have an excellent sterilization rate for a variety of bacteria.

[0014] In addition, in the present invention, the copper ions in the copper ion deodorant can also form a metal-porphyrin complex with the uroporphyrin in cat urine, so that the original green fluorescence in the urine is quenched.

[0063] Test Example 1

[0064] (1) Ammonia deodorization test: 100 g of the pet deodorizing composition prepared in the examples and comparative examples was sprayed on 6 A4 papers three times. After the last spraying, the pets were placed in a 60 L test chamber and allowed to air dry for 5 min. An ammonia release source was placed in the chamber. After the circulating fan was turned on for 2 h, the ammonia concentration was measured by sampling. At the same time, another test chamber was used as a blank chamber. The removal rate was calculated based on the final concentrations of the sample chamber and the blank chamber.

[0065] (2) Test of long-term removal rate of cat urine odor: ① First, cut a 10*10cm polyester cloth; ② Take 10mL of cat urine solution and drop it into the middle of the cloth (0.025g / drop) and let it stand for 1min; ③ The polyester cloth starts in a vertical state, and the pet deodorant composition prepared in the embodiment and the comparative example is loaded into a 30mL spray bottle, and sprayed at a height of 3-4cm on the cloth and at the center of the pollution source, and sprayed with 10mL of pet deodorant composition solution; ④ After waiting for 1min, fan and sniff at 5cm from the cloth. According to the 4-level representation of malodor intensity, the number of sniffing people is 10, and the average score is taken. The scoring details are as shown in Table 1. Then put the contaminated cloth into a sealed bag and evaluate it at 1h, 1D, 2D, and 3D respectively.

[0066] Table 1

[0067] Odor intensity level Odor reaction and description 0 No odor 1 Faint odor (detection threshold) 2 Slight odor (perception threshold) 3 Obvious odor 4 Strong odor

[0068] The evaluation standard is: long-term cat urine odor removal rate (%) = (4-average odor intensity after deodorization) / 4*100.

[0069] (3) Sterilization rate test: refer to the Technical Specifications for Disinfection (2002 edition), and allow the original solution to act for 30 minutes.
