Background

With the popularity of oral knowledge, more and more people are aware of the importance of oral care. Consumers have a strong appeal for whitening teeth, and cleaning of dirt and tooth stains is a basic function of tooth brushing. However, tea-drinking and smoker's tooth surfaces tend to strongly adsorb a dark brown tea stain and smoke stain, and the main reason for the formation of these exogenous stains is the dental plaque on the tooth surface and various colored substances inside the tea stain and smoke stain, exogenous stains that are difficult to remove by electrostatic force, van der waals force and short distance interaction. The traditional toothbrush is difficult to thoroughly remove dental plaque, and the cleaning effect of tooth brushing is greatly reduced due to improper tooth brushing method.

The high-frequency vibration generated by the high-speed rotation of the electric toothbrush can instantly decompose toothpaste into fine foam to deeply clean slits between teeth, and the vibration of the bristles can promote the blood circulation in the oral cavity, thereby having better nursing effect on gingival tissues. A large number of researches show that compared with a manual toothbrush, the electric toothbrush can improve the cleaning power of dental plaque by 38 percent, effectively reduce tooth stains caused by tea drinking, coffee drinking and bad oral conditions, and recover the original color of teeth.

With the advancement of technology and the improvement of living standards, more and more people choose to use an electric toothbrush instead of a traditional manual toothbrush. A large number of studies show that the electric toothbrush is safer than a manual toothbrush, soft and hard tissues are not damaged, and the manual toothbrush is easy to cause tooth abrasion. Some electric toothbrushes on the market at present are provided with force sensors, and can prompt when the force is too large, so that the phenomenon of too large force during tooth brushing is avoided to a great extent. In addition, APP's rising has also promoted the appearance of "intelligence is brushed teeth", through the bluetooth with brush teeth APP and be connected, electric toothbrush can show the time and the route of brushing teeth through the cell-phone to the effect after brushing teeth is evaluated, thereby guides the better brushing teeth of consumer.

For most oral care product manufacturers, it is very difficult to develop an oral care product with high cleaning power and less damage to teeth, and this is often considered. The reason for this is that as the cleaning power of the electric toothbrush is increased, the abrasion of teeth is caused. Therefore, it is desirable to develop an oral care implement with high cleaning power for use with an electric toothbrush to effectively reduce tooth wear and reduce the damage to the teeth and gums.

Test of dentifrice cleaning force

The whitening effect of removing the exogenous stains of the sample is tested by adopting a biofilm Cleaning ratio test (PCR) which can be recommended by ADA (American dental Association) to be specific: making a tooth enamel block by a middle bovine incisor, simulating a human tooth staining environment, staining the tooth enamel block by an in vitro staining way, simulating the frequency of normal tooth brushing by a tooth brushing machine to carry out quantitative tooth brushing times on the stained tooth enamel block, and monitoring the L value of the tooth enamel block before staining and after tooth brushing by a colorimeter; the standard color system of the international commission on illumination (CIE) L a b is the most commonly used color system in dentistry, in which L denotes the visual brightness, a, b denote the hue and chroma, the value of L is 0-100, the brightness is close to white, the small is close to black; the data are analyzed and grouped by adopting span software, the group A is obviously superior to the group B, and the significant difference is achieved; group a was slightly better than group AB, but there was no significant difference; group B was slightly better than group BC with no significant difference; the tooth powders prepared in examples 7 to 9 and comparative example 10 were evaluated for the removal of extrinsic stains from the tooth surface and the cleaning effect of the toothpaste or the tooth powder on the teeth, and the results are shown in Table 6.

Table 6 cleaning force test results

As can be seen from Table 6, the dentifrices of examples 7-9, whether an electric toothbrush or a general toothbrush was selected, had better cleaning power than the dentifrices of comparative example 11. The cleaning effect using the electric toothbrush is also better than that of the ordinary toothbrush for the dentifrice of the same formulation. Thus, the dentifrice using the composition of the present invention has better cleaning effect when used with an electric toothbrush.

Abrasion test of dentifrice

The dentifrices prepared in examples 7-9 and comparative example 11 were tested for abrasiveness, specifically: the Ra (Roughness average) value of the surface of a tooth sample is detected by a surface roughness meter before and after a brushing and grinding test by adopting a surface roughness method, the abrasion degree of the sample to the tooth sample is evaluated by the difference value of the Ra values before and after brushing, and the Ra value is not more than 5.664 mu m, so that the abrasion performance of the tooth powder is safe (3 methods for evaluating the abrasion performance of the toothpaste are compared, Sudoku et al, daily chemical industry, volume 46, 3 rd, page 162, 166, and publication date, 2016, 03 and 31 days), and the results are shown in Table 7.

TABLE 7 abrasion test results

As can be seen from Table 7, the Ra values of the dentifrices of examples 7-9 and comparative example 11 were less than 5.664 μm. It was thus demonstrated that neither the dentifrices of examples 7-9 nor comparative example 11 damaged the teeth and that the dentifrices of examples 7-9 and comparative example 11 reduced wear on the teeth when used with an electric toothbrush.

Dentifrice foaming Performance test

20 persons were randomly selected in the surrounding area of the inventor and the foaming performance tooth brushing sensory test was performed on the dentifrices of examples 7 to 9 and comparative example 10 using an electric toothbrush and a general toothbrush, respectively, and the results are shown in Table 8.

TABLE 8 foaming Property test results

Remarking: score 1-5, score 1 worst, score 5 best

As can be seen from Table 8, the dentifrices of examples 7-9 and comparative example 10 all showed better results in terms of the ability to flash foam, the volume of foam, the smoothness of foam and the mildness when using the electric toothbrush than the ordinary toothbrush; the electric toothbrush is matched with the tooth powder of the embodiment 7-9 for use, so that a tester has better use experience, no dry and astringent feeling in the oral cavity after use, and the overall evaluation is higher. It is thus demonstrated that the use of a dentifrice employing the composition of the present invention in combination with an electric toothbrush results in a better brushing experience for the consumer.

Gloss test of teeth

The toothpastes of examples 7 to 9 and comparative example 9 were used to brush once every morning and night in exactly the same manner except that the toothpastes were different, and the gloss and whiteness of the tooth surfaces after one week were observed, and the results are shown in Table 9:

TABLE 9 evaluation results of tooth gloss

Remarking: score 1-5, score 1 worst, score 5 best

As can be seen from Table 9, the tooth powders of examples 7 to 9 are significantly superior in gloss to comparative example 9 no matter which toothbrush is used for brushing teeth; for the dentifrice with the same formula, the electric toothbrush has more obvious polishing effect on teeth, so that the teeth have better glossiness; the dentifrices of examples 7-9 and comparative example 9, both scored higher on whiteness using an electric toothbrush than a regular toothbrush. Thus, it was demonstrated that the dentifrice of the composition of the present invention effectively enhances the gloss and whiteness of teeth when used in combination with an electric toothbrush.
