Description

Washing-free tear mark removing composition for dogs and cats as well as preparation method and application thereof Technical Field The application relates to the technical field of pet care products, in particular to a washing-free tear mark removing composition for dogs and cats, and a preparation method and application thereof. Background The tear marks of dogs and cats are mainly caused by excessive secretion of tears, obstruction of nasolacrimal ducts and unsmooth discharge, and are accompanied by excessive proliferation of periocular microorganisms (such as malassezia), and oxidation reaction of porphyrin substances in tears and iron ions and deposition on hair. Appears as reddish brown or tan plaques around the eye, which affect aesthetics and may be accompanied by skin inflammation. The existing tear mark removing products are mainly classified into cleaning products, wiping products, powder products and oral products, and most of the products are single in function, or focus on physical cleaning, or focus on antibacterial, and a plurality of key links in tear mark formation cannot be systematically and radically solved at the same time, so that the effect is limited. Therefore, there is a strong need in the art for a leave-on care product that integrates multiple functions, is extremely convenient to use, has high pet acceptance, and can inhibit tear mark formation from multiple targets. Disclosure of Invention Based on the defects of the prior art, the first aim of the application is to provide a washing-free tear mark removal composition for dogs and cats, which has the advantages of multi-target point synergy, excellent film forming lasting effect, convenient use, safety and effectiveness, and can simultaneously realize the functions of inhibiting harmful microorganisms around eyes, blocking tear pigment oxidation, repairing skin barriers and the like. The second aim of the application is to provide a preparation method of the disposable tear stain removing composition for dogs and cats, which is stable in process and suitable for large-scale production. The third object of the application is to provide the application of the washing-free tear stain removing composition for dogs and cats in nursing products for preventing, fading or assisting in treating tear stains of dogs and cats. In order to achieve the above purpose, the technical scheme adopted by the application is as follows: According to the first object of the application, the rinse-free tear stain removing composition for dogs and cats comprises, by weight, 1.5% -2.0% of antifungal agent microcapsules, 0.5% -3.0% of metal ion chelating agents, 2.0% -10.0% of skin barrier repairing agents, 2.0% -8.0% of emulsifying agents, 0.5% -5.0% of film forming aids, and the balance of water and pH regulators. Preferably, the rinse-free tear stain removal composition for dogs and cats comprises, by weight, 1.8% of an antifungal agent microcapsule, 1.5% of a metal ion chelating agent, 8.0% of a skin barrier repair agent, 4.0% of an emulsifier, 2.0% of a film forming aid, and the balance of water and a pH regulator. The composition for removing tear marks for dogs and cats provided by the application has the advantages that all components are mutually synergistic, tear marks are radically relieved by multiple actions of targeting antifungal, efficiently destroying biological membranes, strongly chelating iron ions, catalyzing and removing active oxygen, repairing skin barriers and the like, the composition is mild and non-irritating, dry and non-sticky in touch feeling, cleaning is not needed, and compliance of pets is greatly improved. Further, the metal ion chelating agent is a combination of at least one of phytic acid, EDTA-disodium and lactoferrin and madecassoside, preferably, the metal ion chelating agent is selected from EDTA-disodium, lactoferrin and madecassoside with the mass ratio of (30-45): (45-55): (10-15). The tear stain and the reddish brown color of saliva stain of the pet are derived from porphyrin in the tear stain and the reddish brown color of the saliva stain, wherein iron ions can react with oxygen to generate active oxygen, and the substances oxidize surrounding tissues to generate irreversible brown melanin. The application can chelate and isolate free iron ions, destroy the formation of biological films and reduce pigment deposition by adding metal ion chelating agents, especially EDTA-disodium and lactoferrin in a specific proportion, and can assist in strengthening the chelation of iron by adding madecassoside, which is cooperated with EDTA-disodium and lactoferrin, so as to further improve the tear mark removing effect. Further, the skin barrier repairing agent is at least two selected from trehalose, panthenol, ceramide, phytosterol and cholesterol, preferably, the skin barrier repairing agent is selected from trehalose, panthenol and ceramide with the mass ratio of (4-5): 2-3): 1. The application adopts at least two o
