Description

The present invention relates to a bath composition.

Conventionally, a bathing agent containing a carbonate and an organic acid generates carbon dioxide bubbles in the bath water, and the carbon dioxide gas promotes blood circulation and gives a feeling of warmth. Widely known as an excellent bathing agent. In addition, studies have been conducted to bring about additional effects and synergistic effects by further adding various components to such bath preparations.

For example, Patent Document 1 discloses a composition for a solid bath using malic acid and a specific amount of fumaric acid as an organic acid, and describes that inorganic salts can also be used, and has excellent moldability and moistness. It has a good feeling of use and eliminates floating substances to improve the surface condition of bath water. Further, Patent Document 2 describes a powder containing an organic acid such as citric acid, fumaric acid, tartaric acid, and adipic acid, a carbonate, an inorganic salt such as sodium sulfate and magnesium sulfate, and a specific binder and oil. A solid bath salt having a specific hardness, which is obtained by pressure-molding the above-mentioned powder, is disclosed, and exhibits quick solubility and high foaming power at the time of use to enhance the feeling of use.

On the other hand, it is also known that inorganic salts such as magnesium sulfate are useful in trying to further enhance the warm bath effect in such bathing agents. For example, Patent Document 3 discloses a bathing agent composition containing effervescent granules, an inorganic salt component, and a specific amount of an oily component, and describes that it has a good scent and sufficiently exerts a warm bath effect. Has been done.

By the way, in the field of fragrances, as described in Non-Patent Document 1, powdered or granulated powdered fragrances may be used for various purposes such as storage stability and stability. It is known that this can be obtained by a method such as mixing with a sugar having low hygroscopicity such as lactose or glucose or a soluble starch and pulverizing it.

However, if an inorganic salt hydrate is used as a component of the bathing agent composition in order to enhance the feeling of warmth, and a good fragrance is also given by using a fragrance, in the presence of an organic acid and a carbonate, The coexistence of water molecules contained in the inorganic salt hydrate and the fragrance is the main factor, which not only increases the risk of swelling of the packaging material, but also may cause the bath preparation composition to turn brown during storage. It has been found by the present inventor to increase. Under these circumstances, even if the amount of fragrance is simply increased while using inorganic salt hydrate in the technique described in the above patent document, it is difficult to achieve both an excellent warmth and a good fragrance, and at the time of storage. It was also found that the swelling of the packaging material and the discoloration of the agent could not be sufficiently suppressed, and there was still room for improvement.

That is, the present invention uses an inorganic salt hydrate to effectively enhance the feeling of warmth, bring about a good scent, and effectively prevent swelling of the packaging material and discoloration of the bathing agent composition. Regarding the agent composition.

Therefore, as a result of various studies, the present inventor limited the content of excipients while using a specific amount of each of a perfume particle containing a perfume component and an inorganic salt hydrate in a specific amount in the presence of an organic acid and a carbonate. By doing so, it has been found that a bathing agent composition capable of preventing swelling of the packaging material and discoloration of the bathing agent composition can be obtained while achieving both an excellent warmth and fragrance.
