Description

DENTIFRICE COMPOSITION CONTAINED PINE NEEDLE POWDER [0002]

The present invention relates to a dentifrice composition using a pine needle component as an abrasive, and more particularly to a dentifrice composition comprising a pine needle powder to remove foreign matter and calculus remaining in teeth through a method of rubbing teeth, To toothpaste compositions.

Toothpaste is an abrasive that physically removes the debris on the teeth, a surfactant that helps to effectively remove the stuck residue, an excipient that helps maintain proper viscosity, an excipient that helps maintain shape, A moisturizing agent as a main component, and an additive such as a fragrance, a sweetener, an antiseptic, a coloring agent and the like to suit the taste of a consumer.

Abrasive abrasive wear is important because the dual abrasive is used to physically remove scum on the surface of the tooth, but it can also wear the tooth enamel and dentin.

Typical abrasive agents are calcium monoxide, precipitated calcium carbonate, silica and insoluble meta-oxygen. These abrasives have higher hardness than carbonate apatite, which is a component of tooth enamel. And the dentin is exposed at the thin portion of the enamel at the border of the gum, which causes the gum to swell and feel a severe pain.

In addition, currently used abrasives have an average particle size of 10 to 30 μm, so in order to effectively polish, the amount of addition should be higher than 40% by weight and the brushing time must be increased.

Most people do not feel excited when brushing teeth, but people with sensitive or poor oral health feel excited. These people feel excitement when using toothpaste because of the abrasive that delivers more than necessary force to the surface of the tooth.

In order to prevent the abrasive contained in toothpaste from causing irritation to the teeth and damaging the enamel, it is necessary to replace the abrasive itself with a component of enamel. However, in this case, because the abrasive wear of the abrasive article is lowered, the enamel is protected, but it is difficult to effectively remove the debris adhered to the tooth.

Accordingly, there is a need to develop a toothpaste that provides a soft feeling at the time of brushing and alleviates damage to teeth.

Korean Patent No. 10-1391545 (Announcement 2014.05.02) Korean Patent Publication No. 10-2013-0107397 (published on October 20, 2013) Korean Registered Patent No. 10-0704585 (2007.04.09 Announcement)

Accordingly, an object of the present invention is to provide a dentifrice composition which can effectively adsorb and remove contaminants adhering to a tooth without abrading the tooth surface by adding a fine pine needle powder as an abrasive to a dentifrice composition.

In order to achieve the above-described object of the present invention, in one embodiment of the present invention, in a dentifrice composition containing an abrasive, a surfactant and a solvent, the abrasive is a pine needle powder and the surfactant is a coconut fatty acid or a coconut fatty acid- The present invention provides a dentifrice composition containing pine needle, which is a natural surfactant.

Since the present invention uses fine pine needle powder as a main abrasive, abrasion of the tooth surface is minimized. Accordingly, it is possible to provide a stable brushing effect to infants and adolescents who are relatively immature in dental care while being exposed to soft aged and carbonated beverages, and to aged people with severe tooth wear.

In addition, the present invention promotes a feeling of use of a dentifrice product while helping to reduce irritation in the oral cavity, assists a cleansing action, and is particularly human-friendly by using a natural surfactant instead of an artificially synthesized surfactant.

Hereinafter, a dentifrice composition containing pine needle powder according to preferred embodiments of the present invention (hereinafter, referred to as a dentifrice composition) will be described in detail with reference to the accompanying drawings.

The dentifrice composition according to the present invention comprises an abrasive, a surfactant and a solvent, and may further include at least one of a bactericide, a gum disease prevention agent, a detergent, a dentifrice preventive, a sweetener, a preservative, a flavoring agent, a solubilizing agent, Lt; / RTI >

First, the abrasive agent constituting the dentifrice composition according to the present invention removes food waste and tartar remaining on the tooth surface by acting on the surface of the tooth, and pine needle powder is used.

Conventional abrasives mechanically clean the teeth, that is, polish the surfaces of the teeth to remove food residues and calculus remaining on the surface of the teeth, while pine leaf powder does not abrade the surface of the teeth even when contacted by the toothbrush, Effect. For this purpose, the pine needle powder particles are formed to have a size of 0.1 to 1 mu m.

At this time, if the pine needle powder is formed to have a size of less than 0.1 탆, the rubbing function of the tooth surface is degraded, so that foreign matter and tartar remaining on the tooth surface are not smoothly removed. If the pine needle powder has a particle size exceeding 1 탆, the removal efficiency of tartar and foreign matter may be improved, but the tooth surface may be worn out.

In addition, the pine leaf powder is contained in an amount of 20 to 40 parts by weight based on 100 parts by weight of the solvent. At this time, if the pine needle powder added to 100 parts by weight of the solvent is less than 20 parts by weight, it is difficult to smoothly remove foreign matter remaining on the surface of the tooth. If the pine needle powder added to 100 parts by weight of the solvent is more than 40 parts by weight, the tooth surface may be rubbed against the tooth surface by the toothbrush, but a significant difference is generated as compared with when the proper amount is added Do not.

These pine leaves are difficult to eat because of their unique flavor, but they are made into powder, which is known to have a strong Gangjeong effect when mixed with honey in a solution which is boiled in a weak fire and mixed properly. The pine pine leaves have a unique directional substance of the terpene system and rich in the back, which has a physiological role of stabilizing the nerves of the people.

In Dong-bo-gyung, pine needle has been known to be effective in hypertension, limb dislocation due to peripheral blood circulation disorder, insomnia, paralysis, and nervous breakdown. The pine pine leaves are a key component of the pine needles 'terpen' and 'tannin', which are peculiar to the pine needles. They have low glycemic levels, glycokinin to help diabetes, good iron for anemia, strong capillaries It contains a lot of beneficial ingredients such as routine, apiectin, chlorophyll, beta carotene, vitamin B complex, and vitamin C that remove harmful substances of tobacco.

The surfactant constituting the dentifrice composition according to the present invention activates the surface of the dental calculus attached to the teeth to act to smooth out the dental calculus when brushing. In order to overcome the problems of the conventional surfactant, Natural surfactants derived from fatty acids or fatty acids of coconut oil are used.

More specifically, the natural surfactant may be selected from disodium cocoyl glutamate, sodium methyl cocoyl taurate, and cocoamidopropyl betaine.

Such a surfactant is contained in an amount of 5 to 15 parts by weight based on 100 parts by weight of the solvent. If the amount of the surfactant added to 100 parts by weight of the solvent is less than 5 parts by weight, the generation of bubbles may be reduced during the brushing process, and the removal efficiency of tartar and plaque may decrease.

If the amount of the surfactant added to 100 parts by weight of the solvent is more than 15 parts by weight, it may become difficult to remove the foam by water after tooth brushing, thereby increasing the number of times of rinsing to remove the residues of the toothpaste.

Also, the solvent constituting the dentifrice composition according to the present invention dissolves each component of the dentifrice composition according to the present invention, and purified water such as pure water or the like can be used.

In addition, the dentifrice composition according to the present invention may further comprise pine needle extract.

The pine leaf extract is contained in the dentifrice composition to provide antibacterial and antioxidative functions, and it is contained in an amount of 0.5 to 3 parts by weight based on 100 parts by weight of the solvent.

Specifically, in order to prepare the pine leaf extract, the pine needle collected is washed with water, and the water remaining on the remaining surface is removed by washing with water. Subsequently, the pine needle is crushed and compressed, and then the residue (solid component) is filtered to obtain a liquid extract. According to this extraction method, about 20 kg of pine leaf extract can be produced with 100 kg of pine leaves. At this time, the pine leaf extract may be slightly different depending on the drying state of the pine needle leaf.

 This extraction method can prevent destruction of the active ingredient by heating at a high temperature as compared with the conventional method in which the pine needle is put in water or the like and heated to extract the active ingredient and a liquid extract having a higher concentration of active ingredient Can be obtained, and there is an advantage that the obtaining method is simplified.

The liquid pine leaf extract thus obtained is used at low temperature aging for 1 to 5 years, preferably 2 to 5 years, in order to remove toxins contained in the pine needle itself and to improve antimicrobial and antioxidant functions. At this time, the temperature for low-temperature aging is preferably 1 to 5 占 폚.

If necessary, the pine needle extract according to the present invention may be obtained by fermenting the aged pine leaf extract for a certain period of time.

If the content of the pine leaf extract is less than 0.5 parts by weight, the antimicrobial and antioxidative functions and the release amount of the pine needle extract are decreased. If the content of the pine leaf extract is more than 3 parts by weight, the mechanical properties of the dentifrice composition deteriorate.

If necessary, the dentifrice composition according to the present invention may further comprise at least one selected from the group consisting of a bactericide, a gum disease prevention agent, a detergent, a tooth decay agent, a sweetener, a preservative, a flavoring agent, a solubilizing agent and a wetting agent.

More specifically, any one or more of bamboo salt, sodium chloride, sodium bicarbonate, triclosan, allantoin and propolis may be used as the bactericide, and the dentifrice composition of the present invention may contain 3.0 to 7.0 parts by weight of the bactericide based on 100 parts by weight of the solvent .

Hereinafter, specific examples and experimental examples of the present invention will be described in more detail. It should be understood, however, that the embodiments and examples are for the purpose of promoting understanding of the specific examples of the invention described above, and the scope of rights and the like should not be construed thereby.

[Example] Preparation of toothpaste

The dentifrice composition was prepared in accordance with the conventional dentifrice manufacturing method using the composition ratios shown in Table 1 below. As shown in Table 1, the pine needle powder formed in the sizes of 0.1 to 1 m was added to Examples 1 and 2, the pine needle powder formed in the size of 10 m was added in Comparative Example 1, Instead of the pine leaf powder, calcium carbonate formed to a size of 10 mu m was added. In Examples 1 and 2, coconut fatty acid was added. In Comparative Example 3, a synthetic surfactant was added instead of coconut fatty acid.

[Experimental Example 1] Evaluation of wear of tooth according to particle size

Toothpaste to which pine needle powder having various particle sizes (Examples 1 and 2) and calcium carbonate powder (Comparative Examples 1 and 2) were prepared, and the abrasion resistance of pine leaf powder abrasive by particle size was evaluated.

For this experiment, an artificial tooth having properties similar to enamel of a tooth was prepared. After polishing the artificial tooth with toothpaste, the thickness of the artificial tooth was measured with a Birner Kelpurse.

More specifically, a 200 mm disc with a soft rub on a general grinder was prepared, and the slurry of Table 1 was diluted with water and a weight ratio of 50:50. The slurry was put on a rotating disc in 15 ml increments every 15 minutes. The polishing was carried out at a speed of 100 rpm for 5 hours, the thickness of the artificial teeth after polishing was measured, and the surface changes such as the occurrence of scratches were observed and shown in Table 2 below.

Referring to Table 2, it can be seen that as the pine leaf powder becomes thicker, the wear rate increases. In particular, when the toothpaste containing pine needle powder was used in place of the synthetic abrasive, the surface of the artificial tooth was scratched by a large difference in the average particle diameter of 1 탆 or less (Examples 1 and 2) and 10 탆 or more (Comparative Examples 1 and 2) It is expected that the side effects of abrasion of the tooth surface will be minimized even when used in actual teeth.

[Test Example 2] Evaluation of stability of dentifrice composition

To evaluate the stability of the dentifrice composition according to the present invention, the dentifrice compositions of Examples 1 and 2 and Comparative Examples 1 to 3 were provided to 40 test subjects of men and women over 10 years old, and the degree of stability was evaluated on a scale of 5 points. The evaluation results are shown in Table 3 below.

For this experiment, a mixture solution prepared by mixing the toothpaste of Table 1 and water at a weight ratio of 50:50 was prepared, and the mixture was applied to the subject for 3 minutes, 5 minutes, 10 minutes, 20 minutes, Respectively.

Criteria

5 points: Good (irritation does not occur on the inner wall of the mouth)

3 points; Usually (irritation appears on the inner wall of the mouth),

1 point; Poor (Sore or heterogeneous appearance on inner wall of mouth)

Referring to Table 3, it was confirmed that a low stimulus was generated on the inner wall of the oral cavity when coconut fatty acid, which is a natural surfactant, was used. Particularly, no significant difference was observed in Examples 1 and 2 and Comparative Examples 1 to 3 during the normal brushing time of 3 minutes, but it was observed that the stimulation generated in the oral cavity increased as the time for which the mixed solution was accumulated in the oral cavity increased .
