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
[0004] The existing antibacterial technology is basically limited to surface antibacterial treatment, and its antibacterial effect is reflected in the prevention of secondary pollution. Processing enterprises improve processing conditions and production environment, as well as the promotion of national sound standards and single-piece packaging of sanitary napkins to prevent secondary pollution. The purpose is surface antibacterial technology, but its limitations are getting bigger and bigger. 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 provides an antibacterial agent for sanitary napkins. The antibacterial agent provided by the invention is made from the following raw materials of: by weight, 15-45% of a clathrate, 45-81% of a soluble starch, 2-8% of citric acid, 0.21-0.84% of sodium citrate, 1-2% of carbomer and 0.5-1% of potassium sorbate. The invention also provides a preparation method, which comprises the following steps of: preparing triclosan and cyclodextrin or its derivative into the clathrate by a coprecipitation method, mixing the clathrate with citric acid, sodium citrate, potassium sorbate, carbomer and the soluble starch, granulating, finishing, and finishing particles to obtain the antibacterial agent for sanitary napkins. The invention has the following beneficial effects: the Antibacterial agent for sanitary napkins is designed in allusion to safety risks during the application period of sanitary napkins and can effectively control microbial growth for up to 8 hours during the application period. Safe, high-efficiency and wide spectrum triclosan is selected as an antibacterial component. The beta-cyclodextrin clathrate compound is adopted to enhance the water-solubility of the antibacterial agent. The antibacterial agent provided by the invention has a substantial antibacterial effect and is long-acting.

Description

technical field [0001] The invention relates to an antibacterial product used for sanitary napkins and pads to achieve antibacterial effect, in particular to an antibacterial agent for sanitary napkins and a preparation method thereof. Background technique [0002] The cleanliness and sanitation of menstrual products is particularly important, because the pelvic cavity, uterus, cervix, vagina, and external environment are all connected. This structure makes the female reproductive system particularly vulnerable to external pathogens, especially during menstruation, when the resistance decreases. Infection is especially prone to occur if substandard sanitary napkins are used. [0003] Sanitary napkins directly contact the mucous membranes of the human body and absorb menstrual blood. Menstrual blood is rich in nutrients and can easily become a "medium" for bacteria to multiply. Moreover, the menstrual period is a period when women's body resistance is low. If you don't pay a...
