Problems solved by technology

It can be seen that the use of sanitary napkins will bring potential safety hazards to women, and only effective antibacterial use during use can completely solve the problem for women
[0003] However, the existing antibacterial technology is basically limited to surface antibacterial treatment. Its antibacterial effect is reflected in the prevention of secondary pollution, the improvement of processing conditions and production environment of processing enterprises, the improvement of national standards and the promotion of single-piece packaging of sanitary napkins to prevent secondary pollution. Surface antibacterial technology for the purpose of secondary pollution has more and more limitations. In addition, surface antibacterial technology also has potential safety hazards due to the direct contact of antibacterial components with human skin or mucous membranes.

Abstract

The invention relates to an antibacterial powder for sanitary towels and sanitary pads. A production process comprises the following steps of using 3, 4, 4'-trichlorodiphenylurea and cyclodextrin or a derivative of the cyclodextrin to prepare an inclusion compound through a solid-phase reaction method, mixing the inclusion compound, malic acid, sodium malate, sorbic acid, PVP (polyvinyl pyrrolidone) and soluble starch, and granulating, so as to obtain the antibacterial powder. The antibacterial powder has the beneficial effects that the antibacterial powder is designed for solving the safety hidden dangers in the use process of the sanitary towels, and the growth of microorganisms is effectively controlled for eight hours in the use process; and the safety, high efficiency and broad spectrum of antibacterial components are realized.

Description

technical field [0001] The invention relates to an antibacterial powder used for sanitary napkins and panty liners. Background technique [0002] Due to the special physiological structure of women, the reproductive system of women is particularly vulnerable to the invasion of external pathogens, especially during menstruation, the resistance decreases, and it is more fragile than usual. If you don't pay attention, it is very easy to be infected or cause gynecological diseases. Sanitary napkins directly contact the mucous membrane tissue of the human body and absorb menstrual blood. Menstrual blood is rich in nutrients, which can easily become a "culture medium" for bacteria to proliferate. It can be seen that the use of sanitary napkins will bring potential safety hazards to women. Only effective antibacterial use during use can completely solve the problem for women. [0003] However, the existing antibacterial technology is basically limited to surface antibacterial tre...
