Description

Technical Field

[0001] The invention relates to the field of wet wipe preparation, and more particularly to a pet wet wipe and a preparation method thereof. Background Art

[0002] With the development of social economy and the improvement of people's living standards, pets have become important members of many families. In order to ensure the health and cleanliness of pets, various types of pet care products have gradually emerged on the market. Among them, pet wipes have been widely welcomed due to their convenience and versatility. Traditional pet wipes are mainly composed of fiber cloth and cleaning liquid. Although they can meet basic cleaning needs, they still have some shortcomings in antibacterial, deodorizing and protecting pet skin. In addition, existing pet wipes are mostly made of ordinary non-woven materials. Although these materials have certain water absorption and softness, they lack sufficient antibacterial ingredients. Therefore, they may cause bacteria to grow in long-term use, which will have an adverse effect on the skin health of pets. In addition, the composition ratio of existing wet wipes often focuses on cleaning and moisturizing effects, but there is still much room for improvement in the utilization of natural ingredients and the improvement of functionality.

[0003] For example, the announcement number CN116509732B discloses a cleaning, sterilizing and deodorizing pet sanitary wipes concentrate and a preparation method thereof. After the non-woven fabric is soaked in the concentrate, the cleaning, sterilizing and deodorizing pet sanitary wipes are obtained. The pet sanitary wipes have a pleasant fragrance, a broad-spectrum bactericidal and antibacterial effect, and a good inhibitory effect on viruses, mites, etc. At the same time, they have a good moisturizing, anti-inflammatory and wound healing effect on pet skin. The prior art specifically involves complexing and fixing benzalkonium chloride with hydroxyl, amino, carboxyl and other complexing groups of polydopamine on the surface of modified calcium-magnesium-titanium oxide-coated activated carbon, thereby greatly reducing the concentration of chloride ions in the concentrate, thereby greatly reducing its irritation and toxicity, making it easier to use. At the same time, the complex-type chlorine-containing antibacterial agent can effectively kill bacteria, propagules, spores, viruses and other microorganisms. The stability of the effective chlorine component can reach more than 1 year. Although the technology mentions that the concentration of chloride ions is reduced by complexing with polydopamine on the surface of modified calcium magnesium titanium oxide-coated activated carbon, thereby reducing irritation and toxicity, benzalkonium chloride is essentially a powerful antibacterial agent. If pets lick the parts wiped with the wet wipes, they may ingest a small amount of benzalkonium chloride. Long-term or large-scale intake may cause poisoning symptoms. Long-term exposure to low doses of benzalkonium chloride will cause bacteria to develop drug resistance, making it less effective against other antibacterial treatments in the future.

[0004] This application is based on the optimization of existing technologies and uses natural antibacterial materials to meet the requirements of low-irritation pet wipes. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a pet wet wipe and a preparation method thereof, which can improve the antibacterial, deodorizing and skin care functions of the wet wipe by introducing natural plant extracts and modified bamboo charcoal fibers, while reducing the irritation and toxicity that may be caused by chemical components, so as to achieve gentle and effective cleaning and protection of pet skin.
