Description

Technical Field

[0001] This invention belongs to the field of cat litter technology, specifically relating to a cat litter additive with deodorizing and antibacterial effects and its application. Background Technology

[0002] Cat litter is used by cat owners to bury their cats' feces and urine, and it has good absorbency. Generally, cat litter is made by grinding paper pulp into small granules to simulate sand and provide absorbency. Some also use granules containing physical desiccants such as silica gel, which clump together when exposed to water. Antibacterial agents, deodorizers, preservatives, and other chemical products are usually added. Based on chemical properties and raw materials, cat litter is divided into organic and inorganic types. Organic cat litter includes wood shavings, paper scraps, bamboo litter, grass litter, grain litter, and cereal litter; inorganic cat litter includes bentonite litter, crystal litter, and zeolite litter. From the perspective of material source, cat litter is broadly divided into two categories: plant-based cat litter and mineral-based cat litter. Plant-based cat litter mainly consists of tofu litter and pine litter; mineral-based cat litter mainly consists of bentonite litter.

[0003] Cat excrement can lead to various issues, including loose stools due to indigestion, ammonia-like odor from cat urine, and putrid smells and pathogen proliferation caused by untimely cleaning. Therefore, clumping cat litter, once formed, promotes bacterial growth, which is detrimental to a cat's health. Non-clumping litter, requiring complete replacement, results in significant waste. Currently, some researchers have improved the antibacterial properties of clumping litter by adding antibacterial agents, but this reduces its clumping ability. Furthermore, traditional cat litter deodorization and antibacterial functions rely on external antibacterial agents and fragrance additives, failing to fundamentally address the issue of deodorization and antibacterial properties. Traditional cat litter also has a limited function, serving only as a cover for feces. Existing tofu cat litter typically contains probiotics and deodorizers for antibacterial and deodorizing purposes, but accidental ingestion of these deodorizers can negatively impact a cat's health. Therefore, developing a safe and effective cat litter additive that effectively and stably deodorizes, inhibits bacteria, and repels insects is crucial. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a cat litter additive with deodorizing and antibacterial effects and its application, especially a cat litter additive with deodorizing and antibacterial effects and its application in the preparation of products that remove the odor of pet excrement and / or in the preparation of antibacterial and insect-repellent pet products.

[0071] Application Example 2-3

[0072] This application example provides two types of cat litter with deodorizing and antibacterial effects. The only difference between the formulation and application example 1 is that the cat litter additive in example 1 is replaced with an equal amount of the cat litter additive in examples 2-3. The other ingredients and dosages remain unchanged, and the preparation method is the same as in application example 1.

[0073] Compare and contrast examples 1-8

[0074] This comparative application example provides eight types of cat litter with deodorizing and antibacterial effects. The only difference between the formulation and application example 1 is that the cat litter additive in example 1 is replaced with an equal amount of the cat litter additive in comparative examples 1-8. The other ingredients and dosages remain unchanged. The preparation method is the same as in application example 1.

[0075] Test Example 1

[0076] This test case tests the deodorization performance of cat litter prepared according to test cases 1-3 and comparative application examples 1-8.

[0077] Test conditions: Temperature 20±2℃, relative humidity 50±10%;

[0078] Test method: two 1m 3A sealed glass test chamber with a thickness of 8 mm was used. The inner wall dimensions of the test chamber were 1250 mm (length) × 800 mm (width) × 1000 mm (height). An air sampling port was set in the center of the side wall of the test chamber. A 15 W fan was placed inside the test chamber opposite the air sampling port to uniformly distribute the air inside the chamber. A stainless steel sample rack was placed 300 mm from the bottom of the test chamber along the length of the chamber. The test samples were laid flat on the sample rack to form a 5 cm thick layer of cat litter. Then, a certain amount of ammonia or hydrogen sulfide gas was injected through the air sampling port. After 24 hours, the decrease rate (%) of the ammonia or hydrogen sulfide concentration in the test chamber was measured. The results are shown in Table 1.

[0079] Table 1

[0080] Ammonia concentration decrease rate (%) Hydrogen sulfide concentration decrease rate (%) Application Example 1 77 68 Application Example 2 74 53 Application Example 3 72 55 Comparative Application Example 1 40 35 Comparative Application Example 2 55 52 Comparative Application Example 3 29 39 Comparative Application Example 4 45 32 Comparative Application Example 5 59 46 Comparative Application Example 6 22 25 Comparative Application Example 7 35 39 Comparative Application Example 8 19 21

[0081] As can be seen from the data in Table 1:

[0082] (1) As can be seen from Application Examples 1 to 3, the cat litter prepared by adding the cat litter additive provided by the present invention has excellent ability to adsorb ammonia and hydrogen sulfide gas and has excellent deodorization effect.

[0083] (2) By comparing Application Example 1 with Comparative Application Examples 1-5, it can be seen that when Comparative Application Examples 1-4 do not contain any of Bacillus coagulans, Aspergillus oryzae, Bacillus subtilis, or Bacillus licheniformis, the deodorizing ability of the cat litter additives prepared therein is worse than that of Application Example 1. Furthermore, when Bacillus coagulans BC66 is replaced with an equal amount of commercially available Bacillus coagulans ATCC 7050 bacterial powder in Comparative Application Example 5, the deodorizing ability of the final cat litter product is also worse than that of Application Example 1. It can be seen that the present invention can more effectively improve the deodorizing performance of cat litter by combining and using four probiotics: Bacillus coagulans BC66, Aspergillus oryzae, Bacillus subtilis, and Bacillus licheniformis.

[0084] (3) By comparing Application Example 1 with Comparative Application Examples 6-8, it can be seen that the present invention can synergistically enhance the deodorizing performance of the product by using three plant extracts, namely yucca extract, green tea extract and magnolia bark extract, in combination.

[0092] Test Example 3

[0093] This test case tests the insect-repellent effect of cat litter prepared according to Case 1-3 and Comparative Application Case 1-8.

[0094] Experimental method: 100 Aedes albopictus mosquito larvae were placed in a mosquito cage. Equal amounts of cat litter samples from each group were laid flat in the cage at the same time. The number of times the larvae landed on the cat litter sample within 3 minutes was counted. The experimental results are shown in Table 3.
