Abstract

The invention relates to the field of daily chemicals, in particular to a nanometer plant antibacterial agent for a hand sanitizer and a preparation method. The preparation method comprises the following steps: mixing collected fruit, flowers and leaves of cubeb litsea tree, performing freeze drying, and performing coarse crushing; uniformly dispersing coarse powder in the previous step, sodium chloride, magnesium nitrate and polylysine, carrying out jet milling, and conducting micronizing to a nanometer level under the protection of nitrogen so as to obtain nanometer powder; and adding the nanometer powder into a sodium alginate solution, carrying out ultrasonic dispersion treatment, and carrying out high-pressure spray drying to obtain the nanometer plant antibacterial agent for the handsanitizer. By means of nanocrystallization treatment, the plant antibacterial agent is comprehensively utilized, inactivation of active ingredients of the plant antibacterial active agent is prevented, and complex treatment such as purification and leaching is not needed. The nanometer plant antibacterial agent is suitable for being added into various hand sanitizers and has wide adaptability. Compared with a chemically synthesized antibacterial agent, the antibacterial agent provided by the invention is healthier and environment-friendlier.

Description

technical field [0001] The invention relates to the field of daily chemicals, in particular to a nano-plant antibacterial agent for hand sanitizer and a preparation method. Background technique [0002] Antibacterial hand sanitizer is accepted by more and more consumers as a daily cleaning product. It is used in public places such as hospitals and schools, and has a good instant bactericidal effect. Initially, restricted by living conditions and the market, people usually use soap, soap and washing powder to wash their hands. Although they can achieve a certain cleaning effect, they are irritating to the skin and have poor antibacterial effects. [0003] With the development of antibacterial agents, various antibacterial agents are used in hand sanitizers. However, many antibacterial agents have side effects. Among them, triclocarban and triclosan are the most widely used antibacterial agents, but studies have shown that they are harmful to the reproduction and development...
