Antibacterial composition, antibacterial composite nanoparticle, preparation method of antibacterial composite nanoparticle and targeted sustained-release private nanometer gel

Abstract

The invention provides an antibacterial composite nanoparticle. The antibacterial composite nanoparticle comprises an antibacterial composition and a polylactic acid coating the outside of the antibacterial composition, wherein the antibacterial composition comprises a bacillus subtilis fermentation liquid, a cranberry extract and a herba taraxaci extract. Compared with the prior art, the antibacterial composite nanoparticle has the advantages that a microbicide and an active nanoparticle are coated with the polylactic acid, so that the antibacterial composite nanoparticle can effectively inhibit and sterilize bacteria, can prolong the action time in a sustained-release manner, reconstructs a vaginal bacteria balance and achieves health maintenance of female vaginas.

Description

technical field [0001] The invention belongs to the technical field of personal care, and in particular relates to an antibacterial composition, an antibacterial composite nanoparticle, a preparation method thereof, and a targeted slow-release nano-private gel. Background technique [0002] With the improvement of living standards, people pay more and more attention to their health, and women's private care has become an important part of personal care. According to the survey results, as many as 91% of women are troubled by private discomforts including unclean secretions, itching, and odors, especially during hot weather, menstruation, prolonged sitting in the office, and before and after intimacy. Human papillomavirus (HPV) infection is the most important factor leading to cervical cancer. At present, the HPV infection rate of women in my country is about 16.8%, and in the healthy female population, the HPV infection rate is generally about 13.5%. Therefore, women should ...

Problems solved by technology

As a kind of inorganic spectral high-efficiency bactericidal material, nano-silver is non-irritating to human skin, and is widely used in the preparation of women's intimate gel. For example, the Chinese patent whose application number is CN200810016256.6 discloses a chitosan nano-silver gel and Its application uses chitosan nano-silver as an antibacterial product, but because the nano-silver particles themselves are very easy to agglomerate, which is not conducive to dispersion, and has strong permeability, it is easy to enter the cells of various organs of the human body, causing certain damage to the cell body. Therefore, there are certain restrictions on the use of
