Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an effervescent powder cosmetic.

[0002]

2. Description of the Related Art For example, cosmetics used in facial packs include pastes, creams and foams, which are applied or adhered to the face to permeate the ingredients and fix the skin. It is used, and it is usual to wash and massage before use.

Massage is usually performed by hand, and is commercially performed by using a rotating buff, but it is apt to be performed excessively. However, if the skin is massaged too much, it may become hypersensitive to cosmetics, resulting in a problem of rash or rash on the skin.

[0004] In cold permanent, hair is squeezed, but it tends to be squeezed too much, and in that case, the hair is damaged.

However, no cosmetics of this kind, which can be dispensed with without a massage, have been disclosed at present. Therefore, the inventor of the present invention has developed and applied for a cosmetic that provides a massage effect due to the foaming action. It was pointed out that the cosmetics had the expected massage effect, but it was difficult to know if the reaction was optimal.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a cosmetic having a massaging effect by a foaming action depending on the occurrence of bubbles to the highest degree depending on the color. It is to be able to judge. Moreover, the value as a cosmetics is also improved by it.

[0007]

In order to solve the above-mentioned problems, the effervescent cosmetic composition of the present invention contains a first agent containing sodium hydrogen carbonate and bubbles when mixed with the sodium hydrogen carbonate in the presence of water. It is composed of a second agent containing one or more components of generated citric acid, tartaric acid, lactic acid and ascorbic acid, and different colors dispersed in the first agent and the second agent, respectively, and a color tone is obtained by mixing. It is composed of two colorants A and B, which are changed to notify that it is ready for use, and an active ingredient as a cosmetic contained in one or both of the first agent and the second agent. Having a composition. The cosmetics according to the present invention are normally powdery, as is clear from their composition.

The first agent is made of sodium hydrogen carbonate, and the total amount of 100 parts by weight is preferably 15 to 35 parts by weight.
This is because the first agent and the second agent foam in the presence of water, and the reaction thereof is theoretically determined by the molar ratio, but it was confirmed by experiments that the above range was optimal.

The second agent reacts with the first agent in the presence of water to generate carbon dioxide, citric acid, ascorbic acid, tartaric acid,
It is composed of any one or more of lactic acid, and the composition ratio is preferably 45 to 20 parts by weight based on the weight molar ratio with the first agent. Second
When citric acid, ascorbic acid, tartaric acid or lactic acid is used as the agent, the cosmetics show weak acidity. The acidity and alkalinity can be set arbitrarily, but in the case of the cosmetics according to the present invention, the range of PH4 to 8.5 is good.

In the cosmetic composition according to the present invention, the two colorants A and B are mixed with the first and second agents, respectively, to give a unique color before use and both the first and second agents at the time of use. It is possible to determine that they have been mixed well when a certain color tone is obtained, and an optimum reaction can be performed.

For example, when the first agent is red and the second agent is yellow, when the first agent and the second agent are mixed, the color changes to a darker color. However, due to the coloration of the darker color, the optimum use condition. You can judge that It should be noted that a mixture of two colors that disappears or becomes white is also included.

The first agent and the second agent are adjusted to be mixed in equal volumes so that the discoloration can be performed quickly and the mixing can be performed well. This is because if they are mixed in equal amounts, it is easy to ensure accuracy even with a proper amount. As a colorant,
For example, it is a matter of course to use a safe dye legally prescribed by the Food Sanitation Law and the like, and the amount required for coloring varies depending on the colorant, but generally an extremely small amount is sufficient, so the mixing amount is not specified.

Further, a foaming promoter can be used to assist the generation of bubbles. As this type of promoter, skim milk powder, hydrolyzed gelatin, sodium alginate and the like are used. In addition, the powdered soap itself has an effect as a foaming agent.

[0014]

EXAMPLES Examples will be described below with reference to Tables 1 and 2. Examples I, II and III of Table 1 relate to cosmetics used as rinses or packs and have the following compositions:

[0015]

[Table 1] I. 35 parts by weight of sodium hydrogen carbonate which is a carbon dioxide gas generating agent, 5 parts by weight of skim milk powder as a foaming promoter, 1 part by weight of hydrolyzed gelatin, 1 part by weight of sodium alginate, silicone resin and squalane as a softening agent, and methylparaben as a preservative. 20 parts by weight of lactic acid and 5 parts by weight of ascorbic acid for generating carbon dioxide gas by reacting with the first agent while mixing and mixing yellow iron oxide as a colorant in appropriate amounts. Parts, 15 parts by weight of hydrolyzed gelatin as a foaming promoter, 5 parts by weight of sodium alginate, and an appropriate amount of a softening agent and an antiseptic agent as in the first agent, and a second agent colored red with a red iron oxide, A powdery cosmetic used as a pack was prepared.

II. The amount of sodium hydrogen carbonate as the first agent of Example I was reduced to 25 parts by weight, the skim milk powder was doubled, the amount of the foam promoting agent was increased to 10 parts by weight, and the second agent was tartaric acid 3
The procedure of Example I was repeated except that the amount was changed to 5 parts by weight.

III. Example 1 was prepared in substantially the same manner as Example 1 except that sodium hydrogen carbonate as the first agent was further reduced to 15 parts by weight, skim milk powder was quadrupled, and the second agent was changed to tartaric acid to be 45 parts by weight of citric acid.

Example II. III can be used as a rinse. In addition, although Example I shows alkalinity,
Is almost neutral and III is acidic. The second agent such as citric acid, tartaric acid, lactic acid and ascorbic acid may be used in an amount of about 20 to 45 parts by weight, whichever is used.

[0019]

[Table 2] Next, Table 2 relates to cosmetics used as powder soaps, except that powder soaps are used instead of the skim milk powders of Examples I to III. Although skimmed milk powder is a foam promoting agent, powder soap functions as a foaming agent as described above, and thus has a better foaming property.

IV. The sodium hydrogen carbonate in the first agent was 35 parts by weight as in Example I, and 10 parts by weight of powdered soap and an appropriate amount of squalane and methylparaben were mixed therein, while hydrolyzed gelatin was blended only in the second agent, Others were the same as in Example I, and a cosmetic that can be used as a powder soap was prepared. The colorant was colored yellow and red using the synthetic colorant Yellow No. 4 aluminum lake and red 223, respectively.

V. The sodium hydrogencarbonate in the first agent was 25 parts by weight as in Example II, the powder soap was doubled to 20 parts by weight, and the second agent was 30 parts by weight of tartaric acid.
Prepared as in Example II.

VI. Further, the sodium hydrogen carbonate in the first agent was further reduced to 15 parts by weight, the powder soap was made 30 parts by weight, and the second agent was increased to 40 parts by weight of citric acid.
Prepared as in II.

The acidity and alkalinity of Examples IV, V, and VI are almost the same as those of Examples I to III. This is the case when citric acid alone is used, or when the other acids exemplified are used. But the same.

Method of use In the case of powder pack The product of Example I is used by dissolving it in water. The first agent and the second agent react in the presence of water to generate numerous carbon dioxide gas bubbles and rupture the bubbles, thereby producing an effect equivalent to massaging the skin.

In the case of powder rinses, those of Examples II and III are used for cold permanent waves. The best results are obtained when the two-component cold permanent solution is used between the first and second liquids. The reason is that after the reducing action by the first liquid is finished, the first agent and the second agent according to the present invention are sprinkled on the hair, and the second liquid is applied, so that carbon dioxide gas is immediately generated and the oxidation by the second liquid is performed. This is because it not only assists the action but also provides a rinse effect and a treatment effect to the hair. During this period, the bursting of carbon dioxide gas bubbles produces an action equivalent to the ironing action on the hair.

In the case of powder soaps, those of Examples IV-VI are used with water. For example, when an equal amount of the first agent and the second agent are placed on the palm and an appropriate amount of water is dropped, carbon dioxide gas is generated and bubbles occur. Apply to skin and wash, then rinse off. The foaming action stimulates the skin moderately and makes it comfortable to wash.

[0027]

The present invention is configured and operates as described above, and it is different from the fact that a massaging effect can be obtained by the foaming and bursting action of carbon dioxide gas, and the degree of foaming is in the highest state. Since it can be easily determined by the mixed discoloration of the first and second agents, the method is facilitated and the best foaming state is obtained, so that the value as a cosmetic can be enhanced.
