BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to foamable cosmetics and methods of using the same.

0002

2. Description of the Related Art For example, cosmetics used in facial packs include pastes, creams, and foams. These are applied or adhered to the face to allow the ingredients to penetrate and soothe the skin, and the face is usually washed and massaged before use.

[0003] Massage is usually performed by hand, and commercially it is also performed using a rotating buff, but the massage is often overdone. However, if the skin, which has already been cleansed by face washing, is massaged too much, the skin may become sensitive to cosmetics, resulting in a problem of rashes and rashes on the skin.

[0004] Also, in cold permanents, the hair is squeezed, but there is a tendency to squeeze the hair too much, and in this case too, the result is damage to the hair, just as in the case of excessive massage of the skin.

[0005]Currently, however, this type of cosmetic that can be done without massage has not been disclosed.

[0006]

[Problems to be Solved by the Invention] The present invention has been made in view of the above points, and its object is to obtain necessary and sufficient effects without causing unnecessary stimulation to the skin and hair. That's true.

[0007]

[Means for Solving the Problems] The foaming cosmetic of the present invention that solves the above-mentioned problems comprises a first carbon dioxide gas generating agent (a first
agent), calcium sulfate, citric acid, ascorbic acid,
It consists of a second carbon dioxide gas generating agent (second agent) selected from tartaric acid, and an additive selected from skim milk powder and starch.
10 to 40 parts by weight of the first agent in 100 parts by weight of the total amount, 65
It has a composition containing ~20 parts by weight of the second agent. As is clear from its composition, the cosmetic according to the present invention is normally in powder form. The first agent consists of either one or both of sodium hydrogen carbonate and ammonium hydrogen carbonate, and the proportion thereof in 100 parts by weight of the total amount is 10 to 40 parts by weight, preferably 15 to 35 parts by weight. The reason why the minimum part is 10 parts by weight and the maximum is 40 parts by weight is that the first and second parts foam in the presence of water, but the reaction is determined by the weight molar ratio, so it is wasteful to deviate significantly from that range. This is because it becomes

[0008] The second agent reacts with the first agent in the presence of water and is composed of any one or all of calcium carbonate, citric acid, ascorbic acid, and tartaric acid, which generate carbon dioxide gas. Based on the weight molar ratio, the composition ratio is preferably 65 to 20 parts by weight, preferably 60 to 25 parts by weight.

The first and second agents are also used to change the properties of cosmetics. That is, when calcium sulfate is used in the second part, the cosmetic becomes slightly alkaline no matter what is used in the first part. Furthermore, when citric acid, ascorbic acid or tartaric acid is used as the second agent, the cosmetic exhibits weak acidity. The acidity and alkalinity can be set in any manner, but in the case of the cosmetic according to the present invention, a pH range of 4 to 8.5 is preferable.

[0010] When using the cosmetic according to the present invention as a pack, the difference between acidity and alkalinity serves as a guideline for using the cosmetic according to the nature of the user's skin. On the other hand, when the cosmetic according to the present invention is used for cold perm, calcium sulfate is not suitable as the second agent because it is used together with an oxidizing agent.

[0011] The additive is used to enhance the pack effect, and either one or both of skim milk powder and starch is used, and these give a good feel to the skin and hair when the cosmetic composition according to the present invention is used. It is also possible to change the strength and weakness of the generated carbon dioxide gas bubbles. This composition ratio is 1 to 20 parts by weight, because if it is less than 1 part by weight, the bubbles will become too strong, and if it is more than 20 parts by weight, the bubbles will be too weak. Note that a strong bubble means that it does not burst easily and can therefore give a strong stimulus, and a weak bubble means the opposite.

[0012] One of the other additives may include sodium alginate as a thickener in a range of 1 to 20 parts by weight. Sodium alginate forms a good bubble film, so you can adjust the strength of the bubbles, but if it is less than 1 part by weight, the bubbles and carbon dioxide gas will be generated too strongly, and if it exceeds 20 parts by weight, it will last longer but will become weaker. Pass. It is also used to control the intensity of the sound of the generated bubbles bursting.

Other additives 2 can include magnesium carbonate as a filler. Magnesium carbonate is blended as an inorganic agent that feels good on the skin and hair, and at the same time serves as a desiccant to keep the cosmetic according to the present invention in a dry state until it is used. The ratio is the sum of each composition ratio plus an amount that does not exceed 2 parts by weight, taking the total amount as 100.

Other additives 3 include any one or all of the group consisting of dipotassium glycyrrhizinate, allantoin, water-soluble azulene, chlorophyll, plant powder (herbal medicine), sodium hyaluronate, camphor, menthol, etc. used. These are used for the purposes of preventing chemical burns from perm solutions, cleaning the skin, providing nutrients that contribute to the healing of rough skin, providing water retention, and providing a moderate amount of pleasant stimulation, thereby enhancing the pack effect. The blending ratio may be the same as that normally used in cosmetics.

Similar to cosmetics in general, it may also contain appropriate amounts of preservatives and fragrances.

[0016] In the foaming cosmetic composition having the above composition, the first part and the second part react in the presence of water to generate carbon dioxide gas. Water includes not only tap water but also lotions and aqueous solutions such as oxidizing agents for cold perms. In a typical formulation, it is appropriate to use three times the amount of water by weight relative to the amount of cosmetic used.

When this cosmetic is dissolved in an appropriate amount of water, carbon dioxide gas is generated with a sound within one minute, although there are differences due to room temperature and composition, and the gas continues to form bubbles. Numerous bubbles are formed, swell up as if they were blowing bubbles, and then burst and disappear, but this effect lasts for 2 to 3 minutes to several minutes.

When foamed cosmetics are applied to the skin, hair, etc., countless bubbles are continuously generated, expand, flow, and burst, which irritates the skin, hair, etc. This provides the same effect as a massage. Although the changes in individual bubbles such as foaming, expansion, flow, and bursting are minute, they are repeated countless times and act continuously, so the massage effect is remarkable, and the massage is more consistent with the prescription than artificial massage. Easy to get results.

Cosmetics prepared to be slightly acidic are also used for cold permanents. In that case, after reducing the hair with one permanent wave lotion, the weakly acidic cosmetic according to the present invention, Examples II to IV described below.
, VI to VIII are applied to the hair. This is used in conjunction with an oxidizing agent such as an aqueous solution of sodium bromate, which is part of the permanent wave lotion, but the oxidizing action progresses rapidly because carbon dioxide gas continues to be generated during the action. Therefore, the time is also shortened. It is better to apply the cosmetic according to the present invention to the hair first and then spray the oxidizing agent aqueous solution, but oxidation treatment is also possible by spraying the foamed product on the hair like a pack. be.

[0020] Such foaming cosmetics according to the present invention include:
By mixing some soap ingredients, it can also be used as a facial cleanser that takes advantage of its foaming properties.

[0021]

[Example] I. 35 parts by weight of sodium hydrogen carbonate as the first agent, 60 parts by weight of calcium sulfate as the second agent, 1 part by weight each of skim milk powder and starch as additives, 1 part by weight of sodium alginate, and a separate table of pre-prescribed dipotassium glycyrrhizinate and fragrance. A foaming cosmetic was prepared by mixing the 10 types of powder shown above and the balance consisting of a small amount of magnesium carbonate. This cosmetic is weakly alkaline.

[0022]

[Table 1] II. The sodium bicarbonate in the first part was reduced to 15 parts by weight, the second part was changed to citric acid and reduced to 35 parts by weight, skim milk powder and starch were increased to 15 parts by weight each, and sodium alginate was also reduced to 10 parts by weight. A foaming cosmetic was prepared in the same manner as in Example I except for the following procedures.

III. Part 1: 25 parts by weight of sodium hydrogen carbonate, Part 2: 50 parts by weight of ascorbic acid, 5 parts by weight each of skim milk powder, starch and sodium alginate, balance Table 1
A foaming cosmetic was prepared in the same manner as in Example I using the additives shown below.

IV. 15 parts by weight of first agent sodium carbonate,
A foaming cosmetic was prepared in the same manner as in Example I using 25 parts by weight of second agent tartaric acid, 15 parts by weight each of skim milk powder and starch, 10 parts by weight of sodium alginate, and the remainder the additives shown in Table 1.

The foaming cosmetics of Examples II to IV all exhibit weak acidity. Therefore, for permanent use, those of II to IV are used.

V, VI, VII, VIII. In these examples, as shown in Table 1, the first agent was changed to ammonium hydrogen carbonate, and the second agent and subsequent agents were four types prepared in the same manner as in Examples I to IV above, and agent V was weak. In addition to alkaline, three types are weakly acidic.

[0027] To each of the above-mentioned foaming cosmetics I to VIII, an amount of clean water corresponding to approximately three times the weight ratio was added, respectively, and the mixture was used as a pack agent for the skin. We listened to the impressions of the test subjects and observed the skin, and found that the product felt good during use, and the massage effect of the bubbles was well received as you could choose from various strengths and weaknesses, and no abnormalities were observed. Furthermore, as a result of using cosmetics II to IV and VI to VIII in the oxidation of cold permanent hair, it was confirmed that the treatment time, which conventionally required about 15 minutes, could be shortened to about 7 minutes. It was also popular because unlike conventional lotions, it has foaming properties, so the liquid does not run down the scalp.

[0028]

[Effects of the Invention] Since the present invention is constructed and operates as described above, it can be used simply by adding an appropriate amount of water, and the effect is equivalent to that of a massage without any massage at all. Moreover, it was possible to perform the necessary and sufficient massage without giving any unnecessary stimulation to the skin, hair, etc.
