Preparation and application of an antibacterial lubricant for tampon outer tube

Abstract

The invention belongs to the field of functional hygienic material preparation and discloses application and preparation of an antibacterial lubricant for tampon outer tubes. The technical scheme includes that mixing antibacterial metal oxide, a small quantity of rare earth mineral elements and a complexing agent according to a certain proportion, and gradually dropwise adding into an oil system under a stirring condition to form a stable water-in-oil system; performing reaction in a reaction kettle for 30-120min at 120-170 DEG C, cooling, and centrifuging to separate and remove precipitates to obtain the antibacterial lubricant. The antibacterial lubricant can be sprayed to the tampon outer tubes to make it convenient for implantation of the tubes, an antibacterial effect is achieved, andthe problem of skin allergy caused by organic antibacterial agents commonly used at present and problems of precipitation and color change caused by inorganic silver ion antibacterial agents are effectively solved. The antibacterial lubricant is capable of removing microorganisms on the outer tubes to improve lubricity, is remarkable in antibacterial function, free of irritation and allergy, safeand environmentally friendly and is capable of effectively overcoming current concerns of out-of-limit microorganisms on the tampon outer tubes.

Description

technical field [0001] The invention discloses the preparation of an antibacterial lubricant and its application on the outer tube of a catheter-type tampon, belonging to the field of preparation of functional sanitary materials. Background technique [0002] Catheter-type tampons are favored by many people because they do not affect clothing and sports during use. European and American women use them more. In the United States, 42% of women use tampons. Because Asians do not like suppositories habitually, tampons are rarely used among women in Asian countries. In China, only 2% of women use tampons. The main reason is that many women use it for the first time. Due to lack of experience or the smoothness of the plastic catheter wall, it is difficult to implant it in the body correctly; secondly, many women think that the tampon and the plastic catheter wall are not hygienic enough, and they are worried that bacteria will be introduced into the uterus. Infection increases th...

Problems solved by technology

[0004] The above-mentioned lubricants all use organic antibacterial and anti-corrosion materials, which have poor heat resistance and certain toxicity, which can easily cause irritation and allergies to the skin, and cause bacteria to develop drug resistance and mutate into super bacteria, which is even more harmful to the human body.

Although silver-based antibacterial agents have excellent antibacterial properties, the use of nano-silver also has disadvantages. The most prominent performances are that it is expensive, easy to change color, and the precipitation of silver ions causes pigmentation. In addition, silver ions are easy to cause adverse effects on the environment and human health.
