FIELD OF THE INVENTION [0001] The present invention relates to a composition for preparing a carbon dioxide external preparation, a method for producing the carbon dioxide external preparation, a method for producing the same, a carbon dioxide topical agent,

The present invention relates to a composition used for preparing a carbon dioxide external preparation for mixing two or more agents at the time of use.

There is known a technique for producing a carbonic acid gas by mixing a basic composition containing a carbonate with an acidic composition such as water-soluble acid in the presence of water for the purpose of cosmetic and medical effects (see Patent Document 1, etc.).

In addition, by using a substance that hydrolyzes to generate an acid, a carbonate, a thickener, water, a gelling agent that gels by calcium ions, and a water-insoluble or water-insoluble calcium salt as essential components, carbon dioxide is continuously absorbed percutaneously and lightly It is also known that a carbon dioxide external preparation having a stronger cosmetic and medical effect can be easily prepared (see Patent Document 2, etc.).

The composition for preparing a carbon dioxide external application agent is to mix and react two or more agents when they are used to generate carbon dioxide.

When a composition for preparing a carbon dioxide external preparation is used for a cosmetic pack, a gelling agent which is gelled by calcium ions and a water-insoluble or water-soluble calcium salt are added to a composition for preparing a carbon dioxide external preparation, It is known that it is possible to solidify a composition for use.

However, there has been a problem that the rate of gelation of the composition for preparing a carbon dioxide external preparation and the hardness of the gel are not suitable due to the kind and the blending ratio of the gelling agent and the water-insoluble or water-soluble calcium salt. That is, when the gelation is too fast, the composition for preparing a carbon dioxide external preparation has a problem that spreading on application to skin or the like is poor and sufficient carbon dioxide can not be generated. On the other hand, if the gelation is too slow, the composition for preparing a carbon dioxide external preparation can not be cleanly removed from the surface of the skin by hand, and it is difficult to use the composition as a pack.

The content of the water with respect to the total amount of the composition for preparing a carbon dioxide external preparation for use in the present invention is not particularly limited and may be appropriately selected depending on the purpose. The content is the sum of the water and the water contained in the other components such as the water-soluble calcium salt, and is adjusted so that the total amount of the composition for preparing a carbon dioxide external-use agent is 100% by mass. If the content is less than 55 mass%, the viscosity tends to be high and the fluidity, flexibility, and solubility of other components are lost. Therefore, the content is preferably 55 mass% or more.

Example

Hereinafter, the present invention will be specifically described with reference to examples and comparative examples, but the present invention is not limited to these examples.

(Examples 1 to 9 and Comparative Examples 1 to 3)

According to the composition shown in Table 1, a composition for preparing a carbon dioxide external preparation was prepared. In the examples in which the magnesium salt and the magnesium carbonate serving also as the carbonate were mixed, the composition for preparing the carbon dioxide external preparation was prepared in the form of the magnesium carbonate in the formulations shown in the table. However, , It was considered that the magnesium salt and the carbonate were respectively mixed in the same amount.

According to the blending amounts shown in Table 2, the two divided products were stirred and mixed until they were uniformly observed from the naked eye just before use.

The composition for preparing a carbon dioxide external preparation for use in Examples 1 to 9 and Comparative Examples 1 to 3 was evaluated for the composition for preparing a carbon dioxide external preparation by the following evaluation method, And the ease of peeling at the end of use was evaluated.

The time until the gel is no longer attached to the finger when the application surface is contacted is "the time at which the application surface begins to harden" after the two or more agents are mixed and applied with skin or the like, Time to start hardening ". Next, two or more agents are mixed and applied with the skin, and then the "time until the gel is not left on the skin when it is removed" is set as the "time to peel off" and the "time to peel off" . Then, based on the time of applying the two or more agents after mixing with the skin or the like, a proper "time to start hardening of the application surface" is defined and an appropriate "time to peel off" is specified based on the use time. (?) "When both the " time at which the application surface starts to harden" and the time at which it can be removed are within the specified time, and " Quot ;, and when the one side is within the specified time and the other side is not within the specified time, it is evaluated as "normal (O) ", and when it is not hardened even after 60 minutes from mixing or can not be removed, ) ".

In the examples and the comparative examples described above, since the time for applying the two or more agents of the composition for preparing a carbon dioxide external preparation was mixed with the skin or the like was within 5 minutes, the time for starting the hardening of the appropriate applied surface was 5 to 10 minutes did. In addition, in the examples and comparative examples described, the use time of the composition for preparing a carbon dioxide external preparation was 10 to 15 minutes, and therefore, the appropriate time for peeling was specified to be 10 to 15 minutes.

Table 3 shows the evaluation results of the excellence of spreading upon application to the skin after mixing and the ease of peeling at the end of use.

As can be seen from Table 3, in Comparative Example 2 in which the water-soluble calcium salt is not contained, it can not be removed after the end of use as compared with Examples 1, 2 and 6 which were excellent (?) Evaluation. In Examples 3 and 4, it was found that the spreading time at the time of coating was poor because the time for starting the hardening of the coated surface was short. In Comparative Example 1 in which magnesium carbonate was changed to sodium hydrogen chloride, in Examples 7 and 8 in which the coating surface and the amount of magnesium carbonate were increased, the time for starting the hardening of the coated surface was also deteriorated And it became shorter.

For the composition for preparing a carbon dioxide external preparation for use in Example 1 and Comparative Example 3, the amount of permeable carbon dioxide generated was evaluated by the following method.

For the Examples and Comparative Examples, a microporous film coated with 0.1 g of olive squalene was placed on a container for exclusive use with a carbon dioxide gas concentration meter, in which 1 g of the gel obtained by mixing the two agents described in Table 2 was applied, A detector of a carbon dioxide gas concentration meter is mounted. A predetermined amount of water was added using a syringe to fill the gap between the container and the detector, and the amount of permeated carbon dioxide generated was measured and recorded every minute for 60 minutes immediately thereafter.

The test results of the transmissible carbon dioxide generation amount are shown in Table 4.

Based on Table 4, changes over time in the amount of membrane permeable carbon dioxide generated in Example 1 and Comparative Example 3 are shown in Fig.

From Table 4 and FIG. 1, it can be seen that when Example 1 is compared with Comparative Example 3 which does not contain magnesium ion and water-soluble calcium salt, the permeable carbon dioxide in the up to 15 minutes, Permeable carbon dioxide generated in Comparative Example 3. The amount of the generated carbon dioxide was about 1.2 times that of the membrane permeable carbon dioxide of Comparative Example 3. [

The pH was measured by the following method. The two agents described in Example 1 and Comparative Example 3 were mixed with stirring, and the pH of the composition for preparing a carbon dioxide external preparation was measured with the passage of time using a waterproof type pH meter (HANNA instruments, pHep4 HI98127).

The measurement results of the pH are shown in Table 5 and FIG.

It can be seen from Table 5 and FIG. 2 that in Example 1, the pH was maintained at pH 4.0 to 6.5, which is liable to generate membrane-permeable carbon dioxide, until the pH dropped immediately after mixing of the two agents and elapsed for 60 minutes there was.

It is apparent from Tables 3 to 5 and Figs. 1 and 2 that when the composition for preparing the above-mentioned external preparation for carbon dioxide which is divided into two or more parts is applied on the skin after mixing, the composition for preparing a carbon dioxide external preparation It is possible to provide a composition for preparing a carbon dioxide external preparation for use in which the surface to be coated is not hardened and the composition for preparing a carbon dioxide external-use agent is manually peeled off until the end of use. That is, it was found that when the composition for preparing a carbon dioxide external preparation was spread on skin or the like, it spread well and hardened to a degree that it could be peeled by hand after a lapse of use time.

The composition for preparing a carbon dioxide external preparation for use in the present invention may contain at least one selected from the group consisting of a magnesium salt, a water-soluble calcium salt, a gelling agent gelled by a magnesium ion or calcium ion, a carbonate, a substance which generates an acid by hydrolysis, a polyhydric alcohol, Permeable carbon dioxide generated from a composition for preparing a carbon dioxide external-use preparation which is maintained at a pH of 4 to 6.5 and which is known from Patent Document 2 in a period from immediately after use to end of use, Permeable carbon dioxide was generated.

The above effects are based on several factors. First, the above effect is based on the fact that the ionic crosslinking of a gelling agent such as sodium alginate or xanthan gum is slowed by the addition of a component that generates magnesium ions such as magnesium carbonate, do. The combination of magnesium ions improves the spreading of the composition for preparing a carbon dioxide external preparation immediately after mixing and contributes to solidification of the entire gel. The above effect can be further improved by adding calcium chloride, which is a water-soluble calcium salt, as a component for generating calcium ions, to ion bridging of a gelling agent such as sodium alginate or xanthan gum, Based on that. The mixing of the water-soluble calcium ions contributes to hardening the application surface of the composition for preparing a carbon dioxide external preparation immediately after mixing. The above effect is based on the fact that by increasing the amount of the butylene glycol, which is a polyhydric alcohol, ion crosslinking of the gelling agent can be accelerated. The combination of butyleneglycol contributes to the control of the excellence of the spreading of the composition for preparing a carbon dioxide external preparation immediately after mixing and the detachable time.

The above effect is obtained by adjusting the time at which the surface of the coated layer starts to harden and the time at which it can be peeled by adjusting an appropriate amount of a component for generating magnesium ions such as magnesium carbonate and a water-soluble calcium salt to generate from the composition for preparing a carbon dioxide external preparation Permeable carbon dioxide can be released to the outside of the composition for preparing a carbon dioxide external preparation. The combination of a suitable amount of the magnesium ion-generating component and the water-soluble calcium salt may be a combination of a water-insoluble or water-insoluble calcium salt as a component for generating calcium ions in an appropriate amount and a component known in the art that does not contain a component that generates magnesium ions Permeable carbon dioxide can be generated more than the amount of the membrane permeable carbon dioxide generated from the composition for preparing a carbon dioxide external application agent.

The composition for preparing a composition for external preparation for carbon dioxide of the present invention is easy to mix and prepare with two or more agents and spreads easily so that the surface of the composition does not harden until the application to the skin immediately after mixing and spreads, Permeable carbon dioxide, and can continue to generate a sufficient amount of membrane permeable carbon dioxide within the use time. Therefore, in the cosmetic pack which can appropriately stimulate the skin, it spreads well at the time of application, can be removed cleanly at the end, and also has an effect as a so-called carbonic acid gas pack. And it can be suitably used for any of quasi drugs such as cosmetics, external preparations for skin, hair preparations, medicines, and pet products.

The composition for preparing a carbon dioxide external preparation for use in the present invention is characterized in that it is not compatible with a so-called carbonic acid gas pack on a gel in the cosmetics industry, spreads at the time of application and can be removed at the end of use. Therefore, it is necessary to wipe out a less hard gel that has not been removed at the time of use end so as to use a towel. In addition, a secondary problem has also arisen in the washing treatment of the towel in which the less hard gel is wiped. However, It is also a task to solve.
