Description

Kit for tooth whitening}

The present invention relates to a kit for whitening teeth, and more particularly, to a kit for whitening teeth with excellent whitening effect.

Recently, as public interest in beauty increases, public interest in teeth whitening is increasing. For teeth whitening, toothpaste, mouthrinse, chewing gum, in-room whitening, and most common tooth whitening solutions using trays purchased from store or dentists are used. The tooth whitening solution typically contains an active ingredient that bleaches teeth, such as hydrogen peroxide.

Hydrogen peroxide is well soluble in water, ethanol, and ether, and is slightly acidic due to partial dissociation of hydrogen ions in aqueous solution. This hydrogen peroxide is an unstable substance, and its activity continues to decrease over time. Therefore, conventional tooth whitening products use a hydrogen peroxide stabilizer to maintain activity in order to prevent the activity of hydrogen peroxide from decreasing during distribution.

However, when using actual tooth whitening agents, these stabilizers act as obstacles preventing the activity of hydrogen peroxide, and to solve this problem, a catalyst is used to induce rapid activity of hydrogen peroxide.

On the other hand, tooth whitening agents must be used for a very long period of time, and the degree of improvement is insignificant and the effect is difficult to recognize. In addition, the patch-type product attached to the teeth shows some effect, but it is inconvenient to use and the appearance is not good along with the feeling of foreign body while being attached.

Both topical and adhesive-type whitening agents can cause tooth sensitivity and gingival irritation if the concentration of peroxide is increased for rapid whitening effect. Therefore, there is a need for a solution capable of enjoying a sufficient tooth whitening effect of peroxide and at the same time minimizing stimulation transmitted to the gums and the like.

The present invention relates to a first agent comprising a peroxide;

a second agent including a peroxide decomposition accelerator and an abrasive; and

It relates to a tooth whitening kit comprising an applicator for rubbing the first agent and the second agent applied to the teeth.

In the present invention, teeth whitening can be quickly and conveniently performed using the applicator, and oral irritation can be alleviated.

Oral stimulation as used herein includes any stimulation phenomenon including swelling, redness, pain, etc. appearing on the teeth and gums, which may occur due to the activation of peroxides among tooth whitening ingredients, in particular.

In addition, alleviation means that the above oral irritation is reduced or mitigated, and can be understood as a broad concept including improvement, prevention, treatment, and the like.

In the present invention, the first agent includes peroxide.

The peroxide may impart a whitening effect, and for example, hydrogen peroxide, carbamide peroxide, calcium peroxide, sodium percarbonate, sodium perborate, It may be selected from the group consisting of tetrasodium pyrophosphate peroxidate and mixtures thereof. Specifically, hydrogen peroxide or urea peroxide may be used as the peroxide.

The peroxide may be included in an amount of 0.1 to 50% by weight, 1 to 30% by weight, or 2.5 to 20% by weight based on the total weight of the first agent.

In the present invention, in addition to the peroxide, the first agent may further include a stabilizer to prevent the activity of the peroxide from being lowered during distribution. As the stabilizer, stabilizers commonly used in the industry may be used without limitation.

In the present invention, the second agent includes a peroxide decomposition accelerator and an abrasive.

The peroxide decomposition accelerator can act to promote the activity of peroxide included in the first agent, and also prevent the activity of peroxide from being inhibited on teeth by the stabilizer used for stabilizing peroxide during distribution of the product and can be used to induce an excellent whitening effect.

As the peroxide decomposition accelerator, components for activating peroxide that are generally used in the industry may be used, and for example, a divalent or trivalent metal catalyst, a pH adjusting agent, or a mixture thereof may be used.

The divalent or trivalent metal catalyst can promote the decomposition of peroxide, and examples of the divalent or trivalent metal catalyst include magnesium chloride, magnesium gluconate, iron lactate, iron gluconate iron chloride, manganese sulfate, manganese gluconate, At least one selected from the group consisting of manganese chloride and manganese citrate may be used.

The pH adjusting agent reacts with peroxide to generate a perhydroxyl radical to enhance a tooth whitening effect. Examples of the pH adjusting agent include sodium hydroxide, potassium hydroxide, sodium phosphate, disodium phosphate, trisodium phosphate, sodium pyrophosphate, At least one selected from the group consisting of sodium citrate and EDTA-4Na may be used. The pH adjusting agent may be used in an appropriate amount so that the pH of the composition is 8 to 11.

The peroxide decomposition promoter may be included in an amount of 0.01 to 10% by weight or 0.1 to 5% by weight based on the total weight of the second agent.

The abrasive may be selected from the group consisting of zirconium silicate, calcium monohydrogen phosphate, abrasive silica, precipitated silica, fumed silica, colloidal silica, silica gel, zeolite, calcium carbonate, hydrous alumina, kaolin, cellulose, and mixtures thereof. .

The abrasive may be included in an amount of 1 to 60% by weight or 3 to 40% by weight based on the total weight of the second agent.

In the present invention, the first agent and the second agent described above may be used in formulations such as toothpaste, coating agent, or spray, respectively. As shown in FIG. 1 of the present invention, the first agent and the second agent can be packaged so that they can be separated, and the first agent and the second agent can be applied to the teeth when the agent is applied. At this time, the order of application of the first agent and the second agent is not particularly limited, and the first agent and the second agent are applied sequentially or in reverse order, the first agent and the second agent are applied after mixing the first agent and the second agent, or The first agent and the second agent may be applied simultaneously.

The tooth whitening kit according to the present invention includes an applicator in addition to the first and second agents described above.

The applicator rubs the first agent and the second agent applied to the teeth to obtain a rapid whitening effect due to a complex synergistic effect.

Such an applicator may be composed of a head part for rubbing the first and second agents applied to the teeth and a support part for supporting the head part.

The shape of the head portion is not particularly limited as long as it can rub teeth, and the tip portion may have a simulated shape or a nib-shaped monolith.

In one embodiment, the head portion may be a nib. That is, the applicator includes a nib portion made of a polymer material that rubs teeth; And it may be composed of a support portion for supporting the nip (nib) portion.

As described in FIG. 2, the nib portion may have a nib shape. The size of the nib portion is not particularly limited as long as it is used in the oral cavity, and the length of the cross section may be 1 to 7 mm.

The polymer of the nib portion may be selected from the group consisting of polyester, polyethylene, polypropylene, polystyrene, polyamide, polyurethane, polyacrylate, polybutylene terephthalate, and mixtures thereof. The nip may have a smooth surface without hair.

The support portion may be formed of, for example, plastic, and may have a straight or curved shape. Specifically, the support may have a shape similar to a commercially available brush designed for dental use.

In addition, the present invention provides a tooth whitening method using the above tooth whitening kit.

A tooth whitening method according to the present invention includes applying a first agent and a second agent to teeth; and
