Abstract

The invention provides a bacteriostatic agent and a preparation method thereof. The bacteriostatic agent is prepared from the following raw materials in parts by weight: 10 to 20 parts of radix ophiopogonis extract, 6 to 10 parts of radix rubiae extract, 4 to 8 parts of radix polygoni multiflori extract, 10 to 20 parts of flos chrysanthemi extract and 5 to 7 parts of rhizoma polygoni cuspidati extract. Compared with the prior art, a composition provided by the invention can be dissolved as required by using water or ethanol to be used in a cleaning product, a bactericidal washing agent and thelike. The bacteriostatic agent has a good sterilization effect, and does not have a side effect; a bacterium and a fungus difficultly generate tolerance. Moreover, the preparation method is simple; ause level is small. A bacteriostatic rate to multiple bacterial virus reaches 99 percent or above, and the bacteriostatic effect is obvious.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a bacteriostatic agent and a preparation method thereof. Background technique [0002] Most of the antibacterial agents currently on the market are chemical components as the main components, and the antibacterial effect is not ideal. Moreover, bacteria and fungi are prone to develop resistance after prolonged use, and increasing the dosage will pollute the environment. [0003] Modern people are increasingly pursuing green, environmental protection and high efficiency. A bacteriostatic agent that provides a natural component has a broad market prospect. Contents of the invention [0004] The object of the present invention is to provide a bacteriostatic agent, which contains active ingredient extracts such as Radix Ophiopogon japonicus, Rubia, Polygonum multiflorum, Chrysanthemum, Polygonum cuspidatum, etc., has a synergistic effect on various bacteria and viruses...
