Embodiment 1～6 and comparative example 1～5

[0024] See Table 1 for the raw material formulations of the flake toothpaste additives described in Examples 1-6 and Comparative Examples 1-5.

[0025] The preparation method of the flake toothpaste additive described in Examples 1-6 and Comparative Examples 1-5 comprises the following steps:

[0026] (1), add starch and 70% deionized water, gelatinize at 80°C, add hydroxypropyl methylcellulose and stir evenly to obtain mixture A;

[0027] (2), the mixture A is lowered to room temperature, polyethylene glycol is added, and the mixture is evenly stirred to obtain the mixture B;

[0028] (3), add talcum powder and colorant to part of the deionized water, ultrasonically disperse evenly, add to mixture B to obtain mixture C;

[0029] (4), after dissolving sodium lauryl sulfate and preservative plus deionized water, slowly add in mixture C, stir for 1h, vacuumize to remove the foam in the mixture, bake and dry on the tape casting machine, the drying temperature is lower than Slic...

Embodiment 7

[0033] The flake toothpaste additives described in Examples 1 to 6 and Comparative Examples 1 to 5 were tested for stability, and the flake toothpaste additives were added to the toothpaste, and checked after 0 days, 30 days, 60 days, 90 days, 120 days and 150 days See Table 2 for the test results whether there is dissolution, disintegration or discoloration of the flakes in the toothpaste.

[0034] Table 2 Stability test results

[0035]

[0036] Note: "√" indicates that the flake toothpaste additive did not dissolve, disintegrate and decolorize in the paste; "×" indicates that the product dissolved, disintegrated or decolorized in the paste.

[0037] As can be seen from the stability test results in Table 2, the flake toothpaste additive described in Examples 1 to 6 can maintain good stability after 180 days, and there is no dissolution, disintegration and decolorization in the toothpaste paste; and The flake toothpaste additive described in Comparative Examples 1 to 5 i...

Abstract

The invention discloses a flake toothpaste additive, which comprises the following components by weight: 4-8 parts of hydroxypropyl methylcellulose, 1-5 parts of starch, 0.5-3 parts of filler, 0.5-3 parts of plasticizer and 0.1-1 part of a cosolvent. The flake toothpaste additive of the invention is a water-soluble additive, and has the following advantages: 1, the additive has the function of cleaning teeth and protecting teeth; 2, the raw materials are reasonably matched, and can be uniformly fused together; 3, the obtained additive has good film forming property, is easy to follow-up drying; 4, the flake has good stability after being added to the toothpaste product; 5, the flake has good solubility, and when the toothpaste is used, the flake can be dissolved by an external force; and 6, the flake toothpaste additive plays a role in increasing beauty and synergism. The invention also discloses a preparation method of the novel flake toothpaste additive.

Description

technical field [0001] The invention relates to a toothpaste additive, in particular to a novel flake toothpaste additive and a preparation method thereof. Background technique [0002] At present, domestic flake toothpaste additives mainly rely on imports, and there is a gap in domestic technology. The existing flake toothpaste additives have poor film-forming property, slow dissolution rate and poor stability in toothpaste. [0003] Thin-flake toothpaste additives, various colors, endow the toothpaste with rich senses, and can contain various ingredients such as flavor correction, refreshing, anti-inflammatory, and nutrition. It does not dissolve, disintegrate, or discolor in the paste, maintains its complete shape and color, and breaks or dissolves when brushing your teeth. At present, only a few brands of toothpaste such as Colgate have added flake toothpaste additives in China, and they are all imported products. Contents of the invention [0004] The purpose of th...
