Embodiment Construction

[0009] 1 Chitosan extraction, purification and molecular weight modification. (commodity)

[0010] (1) Shells of crustaceans or other invertebrates are sorted and washed to remove impurities;

[0011] (2) After drying at room temperature, pulverize into 50-70 meshes; soak with 4-6% HLC alcohol to remove calcium and phosphorus;

[0012] (3) Washing with clean water at room temperature. When washing to pH 5.5-6.5, add 10% NaOH at 90-95°C for 2-4 hours to degrease and deproteinize;

[0013] (4) Wash with water to PH5.5-6.5, add 40% NaOH, deacetylate at 90°C for 24 hours, then wash with water to PH5.5-6.5, dry at 100°C to obtain chitosan, and grind to ? eye, spare;

[0014] (5) Modify the molecular weight of chitosan to 270,000-350,000 by conventional acid modification method.

[0015] 2. Preparation of toothpaste

[0016] (1) Glue making: Take 180g of sorbitol, 2g of saccharin, 25g of borax, 1g of CMC, and 280g of water and add them to the glue making tank, and stir evenly;...

Abstract

A chitin tooth-paste with high sterilizing and disinfecting effect and no damage to the teeth and soft tissue in oral cavity is prepared proportionally from foaming agent, sweetening agent, flavouring agent, antisettling agent, mineral rubbing agent, inorganic inflammation-relieving agent, water and the chitosan playing the rubbing role.

Description

technical field [0001] The invention belongs to the technical field of daily hygiene products, in particular to a toothpaste, and its classification position is A61K7 / 16. Background technique [0002] At present, there are only a small number of people who do not suffer from dental diseases, and the prevention and treatment of dental diseases is an important topic of universal significance. In this case, expanding the health care and therapeutic effects of toothpaste for daily cleaning of teeth has attracted much attention from dental research, treatment personnel and toothpaste. Manufacturers pay attention to. Although there are various medicated toothpastes on the market, they have not yet formed a product that is unanimously recognized by users. This shows that the health care and therapeutic effects of the past medicated toothpastes are not as advertised by the manufacturers and expected by users. [0003] The unique physical and chemical properties and biological acti...
