Problems solved by technology

Soluble zinc salts, such as zinc citrate, have been used in dentifrice compositions, however the use of zinc salts can have disadvantages such as the possibility of imparting an astringent taste to oral care products, an unpleasant taste that inhibits their mass appeal use in products, and such flavors may also impose some restrictions on the flavors that can be used
Use of less soluble zinc salts may reduce astringency in oral care products, but also reduces beneficial effects of zinc
Finally, zinc ions can react with anionic surfactants such as sodium lauryl sulfate, thus interfering with lathering and cleaning
Zinc oxide and insoluble zinc salts, on the other hand, do not deliver zinc to teeth well due to their insolubility

Abstract

The invention provides an alginate dentifrice composition, belonging to the field of personal care products. The alginate dentifrice composition comprises alginate, a zinc ion source, a fluorine-releasing anti-caries agent provided by a nano-scale fluorine-doped zirconia powder, and a desensitizing material provided by a bioactive glass microsphere loading a catechinic acid substance. A method forpreparing the alginate dentifrice composition includes combining the liquid material and the powder material in the raw materials to prepare a mixture, and then combining a surfactant into the mixture, and mixing in a vacuum environment to obtain the dentifrice composition. The astringency of the dentifrice composition is neutralized, and the dentifrice composition can reduce hypersensitivity ofdentin, induce enamel regeneration and enhance porcelain gloss of the tooth surface, relieve oral mucosa, periodontal tissue and pulp damage, and promote formation of prothrombin to reduce bleeding time of gums. The preparation method can promote the phenomenon of agglomeration of anti-caries agent particles and generate tetragonal phase crystals, reduce system energy consumption, increase glass particle loading capacity and hydroxyapatite mineralization production, and improve resource utilization rate and effective yield.

Description

technical field [0001] The invention belongs to the field of personal care products, and in particular relates to an alginate dentifrice composition and a preparation method thereof. Background technique [0002] Dentifrices are used to clean teeth, and in addition to removing plaque from tooth surfaces, toothpastes also help remove food particles and discoloration caused by substances such as tobacco, tea or alcohol. Toothpaste also polishes teeth. The products we enjoy as consumers unfortunately often have a negative impact on our teeth. Acidic beverages and desserts, for example, cause tooth erosion by attacking the enamel that coats and protects teeth. In addition, tobacco products and beverages such as coffee and tea can stain teeth and thus make smiles generally unattractive. In addition to the products we consume, there is a constant shift in the natural balance between dental hydroxyapatite (HAP) dissolved from tooth enamel and HAP formed on or in teeth from subst...
