Description
Technical Field
The invention belongs to the technical field of cosmetics or similar cosmetic preparations characterized by components, and particularly relates to an oral care composition used in cooperation with an electric toothbrush and a preparation method thereof.
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.
