Liquid invisible mask with broad-spectrum bacteriostasis as well as preparation method and use method thereof

Abstract

The invention belongs to the technical field of isolation and antibacterial protective materials, and particularly relates to a liquid invisible mask with broad-spectrum bacteriostasis as well as a preparation method and use method thereof. The liquid invisible mask is a film layer covering the surface of mucosa in the nasal cavity, the oral cavity or the throat, and the film layer comprises garlic extract with the allicin content larger than 45%, sesame essential oil and whipping cream; and the mass ratio of the garlic extract to the sesame essential oil to the whipping cream is (70-85): (10-20): (5-10). The garlic extract with the high allicin content is used as an active ingredient, so that the basic effects of sterilization and disinfection are guaranteed; meanwhile, the sesame essential oil is used as a film-forming carrier material, and the whipping cream is used as a framework material; and through the synergistic effect of the three materials, on the premise that the use safetyis guaranteed, while the sterilization and bacteriostasis effects are improved, the adsorbability, the stability and the use comfort of the film layer are remarkably improved, so that the long-actingprotection effect is exerted to the maximum extent, and a remarkable effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of isolation and antibacterial protective materials, and in particular relates to a liquid invisible mask with broad-spectrum antibacterial and its preparation method and use method. Background technique [0002] The nasal cavity is the two gates guarding the respiratory tract. When small particles enter the nasal cavity through the protective mask, some of the particulate matter will be absorbed by the mucous membrane in the nasal cavity and be blocked from the upper respiratory tract. However, due to the limited adsorption capacity, there are still protection loopholes. [0003] The existing commercial masks are mainly divided into cotton masks, medical non-woven masks, activated carbon masks, dust masks, and N95 masks. Among them, cotton masks are suitable for wearing in winter, mainly to prevent freezing. Medical non-woven masks are mainly used to prevent germs, and filter out 90% of 5μm particles, whic...

Problems solved by technology

However, it is found in actual research that the stability of the film layer is poor, and the bactericidal effect of the modified chitosan and garlic extract has been lost before being fully brought into play, resulting in the user having to replenish the liquid medicine several times a day, which greatly increases the economic cost; and More importantly, due to the addition of modified chitosan and a large number of auxiliary materials, the safety of long-term use cannot be guaranteed
