Abstract

The invention discloses preparation and application of nisin, cetylpyridinium chloride and sodium fluoride mouthwash and belongs to the technical field of personal hygiene care. The mouthwash has important effects in oral medicine. However, safety and wound restoration capability of the mouthwash influence the clinical effect. The antibacterial anti-inflammatory mouthwash has an obvious restoration effect on oral ulcer, contains natural antibacterial anti-inflammatory components and has the advantage of rapid restoration of oral ulcer wound.

Description

technical field [0001] The invention belongs to the technical field of personal hygiene care, and relates to a compound mouthwash for treating oral ulcers. Background technique [0002] Nisin is a small molecule polypeptide compound composed of amino acids produced by the fermentation of Streptococcus lactis, which can effectively inhibit the growth of Gram-positive bacteria, and also has a strong effect on bacteria such as Streptococcus mutans and Lactobacillus that cause dental caries. inhibitory effect. Many countries and regions have approved it as a food preservative, and it is used in canned food, vegetable protein food, dairy products and meat products. Because it is easily degraded by some proteases in the human digestive tract and will not accumulate in the human body, it is a safe and natural preservative recognized worldwide. Currently, nisin is not used in oral care products. Therefore, the use of nisin in oral mouthwashes remains to be developed. [0003] Ce...
