Description

  The present invention relates to a carbon dioxide foaming bath agent composition.

  Conventionally, a bath preparation containing an organic acid and a carbonate generates carbon dioxide gas in the bath water, and therefore, such a carbon dioxide gas can bring about various effects such as promoting blood circulation and enhancing a feeling of warming. Therefore, it is widely used as an excellent bath agent.

  For example, Patent Document 1 discloses a solid bath agent obtained by pressure molding a powder containing an inorganic acid such as anhydrous sodium sulfate together with an organic acid such as citric acid and a carbonate, and is excellent. It shows that the effect of bringing about a good feeling of use can be obtained by exhibiting flexibility and foaming power. Patent Document 2 discloses a swelling improving composition containing a carbon dioxide generator such as organic acids and carbonates and inorganic salts such as sulfates and chlorides. It shows that the effect of improving swelling can be obtained by putting it in bath water and immersing its legs and half body.

  On the other hand, an inorganic salt such as magnesium sulfate is known to exhibit an excellent warm bath effect when blended with a bath agent, but for example, as described in Patent Document 3, together with a water-soluble polymer When the blended powder bath agent is stored in a packaging material with high moisture permeability, a caking phenomenon occurs. Therefore, Patent Document 3 attempts to prevent the composition in the packaging material from being consolidated by adding a water-soluble polymer such as magnesium sulfate and a cellulose derivative to the powder bath composition.

  Under these circumstances, it is expected that the feeling of warming can be further enhanced not only by carbon dioxide but also by an inorganic salt if an inorganic salt such as magnesium sulfate is used in combination with foaming by adding an organic acid and a carbonate. The

  However, in the bath agent composition having carbon dioxide foaming properties as described in Patent Documents 1 and 2, when the hydrate is used as an inorganic salt, it is excellent in handling property and economy, but in the composition Since water molecules intervene in this, the storage stability may be reduced. In addition, as described in Patent Document 3, even when a water-soluble polymer such as a cellulose derivative is used in combination, a carbon dioxide foaming composition coexisting with an organic acid or carbonate is sufficient. There is a high possibility that the storage stability cannot be ensured, and further improvement is required to effectively prevent the swell of the packaging material containing such a composition.
