Toothpaste with good mild thixotropy and preparation method of toothpaste

Abstract

The invention provides toothpaste with good mild thixotropy. The toothpaste is prepared from the following components in percentage by weight: 15 to 50 percent of humectant, 10 to 30 percent of main abradant, 0 to 20 percent of auxiliary abradant, 0.5 to 3.0 percent of thixotropic agent, 0.1 to 2.0 percent of thickener, 1.0 to 10 percent of foaming agent, 5.0 to 15 percent of flavoring agent, 0.1 to 3.0 percent of spice, 0.02 to 3.0 percent of bacteriostatic agent and the balance of deionized water, wherein the main abradant is cellulose or microcrystalline cellulose porous particles with the particle size of 70 to 400mu m; the auxiliary abradant is one or more of calcium carbonate, calcium hydrogen phosphate dehydrate and calcium gluconate; the thixotropic agent is formed by the following steps: firstly, dispersing xanthan gum into water; secondly, adding microcrystalline cellulose porous particles with the particle size of 0.1 to 20mu m, and homogenizing the microcrystalline cellulose porous particles to be sufficiently dispersed; thirdly, performing spray drying to obtain a final product; the weight percentage of the xanthan gum in the thixotropic agent is 10 to 20 percent, and the weight percentage of the microcrystalline cellulose porous particles in the thixotropic agent is 80 to 90 percent. The toothpaste provided by the invention has the advantages of excellent cleaning effect, less wear to tooth enamel and good thixotropy; during tooth brushing, a toothpaste body cannot fall off along with foam. The invention also provides a preparation method of the toothpaste.

Description

technical field [0001] The invention relates to a toothpaste, in particular to a mild toothpaste with less wear on tooth enamel, and more particularly to a toothpaste with good mild thixotropy which has less wear on tooth enamel and can increase product thixotropy. The invention also relates to a preparation method of the toothpaste with good mild and thixotropic properties. Background technique [0002] With the improvement of people's living standards, good hygiene habits are paid more and more attention by people. Toothpaste is the most commonly used oral care product in people's daily life, and its efficacy and safety have attracted more and more attention. Toothpaste usually contains abrasives, humectants, foaming agents, thickeners, preservatives, flavor enhancers and water, etc., because hydrated silica (silicon dioxide) with a certain particle size can well remove tooth attachments and dental bacteria Therefore, most traditional toothpastes use hydrated silica as t...

AI Technical Summary

Problems solved by technology

Toothpaste usually contains abrasives, humectants, foaming agents, thickeners, preservatives, flavor enhancers and water, etc., because hydrated silica (silicon dioxide) with a certain particle size can well remove tooth attachments and dental bacteria Therefore, most traditional toothpastes use hydrated silica as their main grinding agent. Although those skilled in the art have made many improvements in the formula of toothpaste products in recent years, most of them are from whitening, anti-moth and other functional properties. On the one hand, the abrasive still uses hydrated silica, such as the Chinese patent application with the application number CN201510983752.9 and the name "A Whitening and Protective Toothpaste", the content of hydrated silica is still 16%-18%; due to the hardness of hydrated silica It is located between the enamel and cementum of the teeth. After years of brushing, the enamel on the surface of the teeth will be severely worn, which will easily lead to dental diseases. According to relevant surveys, children aged 2-6 will swallow 1 / 2 8-1 / 4 toothpaste. Therefore, it is the development trend of toothpaste products to find a soft abrasive with strong adsorption, excellent cleaning power and edible ingredients to replace the current hard hydrated silica abrasive.

[0003] In addition, the existing toothpaste systems often use sodium carboxymethyl cellulose, sodium alginate, etc. as thickeners. The toothpaste made by this kind of thickener is usually relatively viscous, and the extruded toothpaste often has a trailing string In the case of brushing teeth, because the toothpaste paste is relatively viscous and the thixotropy speed is not fast enough after touching the teeth, the toothpaste paste will often fall with the foam, which will not only cause a certain amount of waste, but also undoubtedly A major deficiency of the existing formula system, therefore, developing a toothpaste with good thixotropy is also a problem that those skilled in the art are working hard to solve
