JP6340683B2 - Carbon dioxide generating composition - Google Patents

Description

  The present invention relates to a composition that generates and solidifies carbon dioxide by mixing two or more kinds of compositions that are preferably used in a peel-off type pack.

Conventionally, carbon dioxide has been known to provide beauty and medical effects by improving blood circulation and activating metabolism, and is used in cosmetics such as creams, packs, gels, pastes or masks.
For example, in Patent Documents 1 and 2, carbon dioxide is generated by mixing a basic composition containing water, a thickener and a carbonate, and an acidic composition containing water, a thickener and an acid. A two-part composition is disclosed.
On the other hand, Patent Document 3 describes a peel-off type pack in which a composition using tamarind gum is gelled and solidified and then peeled off.

In the two-component composition of Patent Document 1 above, carbon dioxide is retained without dripping, but since it does not solidify in the final state, it is necessary to wash away or wipe off. In such a composition that generates carbon dioxide, if it can be solidified while retaining carbon dioxide, the composition can be removed by peel-off without passing through a step of washing away or wiping off, and it is very useful. It becomes simple.
However, the present situation is that it is not studied to solidify and peel off while utilizing gelation with tamarind gum and retaining carbon dioxide in the composition.

  The present invention has been made in view of the above problems, and in a mixed composition obtained by mixing two components of an acid-containing composition and a base-containing composition, carbon dioxide is retained in the composition, An object of the present invention is to provide a two-component carbonic acid generating composition that can be solidified and peeled off.

  The inventors have determined that by selecting a specific thickener in the acid-containing composition and the base-containing composition, carbon dioxide is retained after mixing, and after the mixture is applied, it can solidify and peel off. The headline and the present invention were completed.

That is, the present invention provides a carbon dioxide generating composition that holds carbon dioxide generated by mixing (A) an acid-containing composition containing an acid and (B) a base-containing composition containing a carbonate. Because
The composition after mixing is characterized by containing tamarind gum, polyhydric alcohol, water, and cellulose or a cellulose derivative.

  By applying the mixture of the two-component carbon dioxide generating composition of the present invention to the skin, the generated carbon dioxide can be continuously maintained in the mixture, so that carbon dioxide is continuously supplied to the skin. Since blood circulation of the skin can be continuously promoted at a desired location, and the mixture after application can be solidified and peeled off, it is not necessary to wipe off or wash away, and can be used conveniently.

  Hereinafter, embodiments of the present invention will be described.

The above (A) and (B) are supplied in the form of being individually packaged, separately packed in one packaging form having a partition, etc., and (A) and (B) are mixed at the time of use. . When (A) and (B) are mixed, carbon dioxide is generated, and the generated carbon dioxide can be held in the composition after mixing. Furthermore, since the composition after mixing is gelled and solidified, it can be peeled off. This makes it possible to continuously supply carbon dioxide to the skin at a desired location, especially when applied as a pack to the skin such as the face, and it is not necessary to wash off or wipe off just by finally peeling off. It will be very easy to use.

  Both (A) and (B) are preferably fluid gel or liquid. This makes it easier to mix (A) and (B) more uniformly, so that the generated carbon dioxide can be uniformly held in the mixture, and can be solidified more uniformly, facilitating peel-off. It becomes.

If the amount of the acid is 0.1% by weight or less, no matter how much the amount of carbonate that reacts with this acid, the amount of carbon dioxide generated will be small and beauty or medical effects may not be obtained. . When the amount of the acid blended is 10% by weight or more, when an equivalent amount or more of the carbonate is reacted chemically with this, a large amount of carbon dioxide is generated, and the mixed composition contains too many bubbles of carbon dioxide. Therefore, the viscosity in the mixed composition may be reduced. Therefore, dripping occurs and it becomes difficult to supply desired carbon dioxide to the skin, and sufficient cosmetic or medical effects may not be obtained.

(B) The carbonate in the base-containing composition is not particularly limited as long as it reacts with the acid in the acid-containing composition to generate carbon dioxide. For example, ammonium carbonate, ammonium bicarbonate, potassium carbonate, potassium bicarbonate, sesquipotassium carbonate, sodium carbonate, sodium bicarbonate, sodium sesquicarbonate, lithium carbonate, lithium bicarbonate, lithium sesquicarbonate, cesium carbonate, cesium bicarbonate, sesquicarbonate Examples include cesium, magnesium carbonate, magnesium hydrogen carbonate, calcium hydrogen carbonate, calcium carbonate, magnesium carbonate hydroxide, and barium carbonate, and one or more of these are used.

When the amount of carbonate added is 10% by weight or more, when an equivalent amount of acid is reacted chemically with this, a large amount of carbon dioxide is generated, and the mixed composition contains too many bubbles of carbon dioxide. Therefore, the viscosity in the mixed composition may be reduced. Therefore, dripping occurs and it becomes difficult to supply desired carbon dioxide to the skin, and sufficient cosmetic or medical effects may not be obtained.

The tamarind gum is preferably contained in any of the above (A) and (B). After mixing (A) and (B), this tamarind gum can be solidified to the extent that the mixture can be peeled off by acting with a polyhydric alcohol. The tamarind gum is preferably blended so as to be 0.1 to 10% by weight based on the mixture of (A) and (B).
Furthermore, it is preferable that tamarind gum is contained in the above (B). This is because tamarind gum tends to be easily altered by acid, and storage stability can be improved by blending with (B) containing a base.

  It is preferable that water is contained in one or both of the (A) and (B). The blending amount of water is preferably 10 to 60% by weight, more preferably 20 to 50% by weight, based on the total amount of the mixture of (A) and (B). The blending amount of water may be an amount necessary for reacting the acid and carbonate contained in (A) and (B).

In the present invention, it is preferable to use one kind selected from glycerin, diglycerin and polyglycerin from the viewpoint that the effect of solidifying by combination with tamarind gum is high.
The polyhydric alcohol may be blended in any of the compositions (A) and (B) blended with the tamarind gum. In this case, the amount of the polyhydric alcohol acts as a thickener in the composition. However, it is preferable that the amount be less than 10 times that of tamarind gum.
Since the polyhydric alcohol acts with tamarind gum when (A) and (B) are mixed to solidify the mixture, the polyhydric alcohol is preferably contained in an amount 10 times or more of the tamarind gum in the mixture. Therefore, in any of the compositions (A) and (B) that do not contain tamarind gum, it is preferable to use only a polyhydric alcohol as a solvent.
