しかしながら、従来の入浴剤では入浴後のあたたまり感が十分でなく、さらにあたたまり感が高く、肌感触の良好で、かつ保存安定性の良好な浴用剤が望まれていた。   However, a conventional bath preparation does not have a sufficient feeling of warming after bathing, and further, there has been a demand for a bath preparation having a high feeling of warmth, good skin feel, and good storage stability.

そこで本発明者は、浴湯に投入したときに炭酸ガスを発生するタイプの浴用剤におけるあたたまり感を向上させるべく種々検討した結果、従来は水に溶解した炭酸ガスが血行を促進すると考えられていたため、あたたまり感を向上させるためには、炭酸ガスをより高濃度に水中に溶解させることが必要とされていた。ところが、炭酸ガスは油性成分の種類により、水よりも多量に分配する場合があることが判明した。そこで、炭酸ガス発生物に多量の油性成分を配合した浴用剤を製造しようとしたところ、炭酸ガス発生物と油性成分が組成物中で反応してしまい、安定な組成物を得ることが困難であった。さらに検討した結果、炭酸ガス発生物と油性成分とを別個に準備して2剤式とし、入浴時にほぼ同時に浴湯に投入すれば、単に湯中に炭酸ガス発生物を投入した場合に比べて高濃度の炭酸ガスが浴湯中に分配する結果、より高濃度の炭酸ガスを皮膚に供給することができ、よりあたたまり感が向上し、肌感触の良好で、かつ保存安定性も良好な浴用剤が得られることを見出した。   Therefore, the present inventor has made various studies to improve the warm feeling in a bath agent that generates carbon dioxide gas when poured into bath water. Conventionally, carbon dioxide dissolved in water is believed to promote blood circulation. Therefore, in order to improve the warm feeling, it has been necessary to dissolve carbon dioxide gas in water at a higher concentration. However, it has been found that carbon dioxide may be distributed in a larger amount than water depending on the type of oil component. Therefore, when an attempt was made to produce a bath preparation containing a large amount of an oil component in a carbon dioxide gas product, the carbon dioxide gas product and the oil component reacted in the composition, making it difficult to obtain a stable composition. there were. As a result of further investigation, if the carbon dioxide generator and the oil component are prepared separately to form a two-component system, and poured into the bath water almost simultaneously with bathing, compared to the case where the carbon dioxide generator is simply put into the hot water. As a result of the distribution of high-concentration carbon dioxide in the bath water, a higher-concentration carbon dioxide gas can be supplied to the skin, the feeling of warmth is improved, the skin feel is good, and the storage stability is also good. It was found that an agent can be obtained.

すなわち、本発明は、(A)炭酸ガス発生物を含有する浴用剤組成物と(B)油性成分を含有する浴用剤組成物とからなる2剤式の浴用剤を提供するものである。   That is, the present invention provides a two-part bath agent comprising (A) a bath agent composition containing a carbon dioxide generator and (B) a bath agent composition containing an oil component.

本発明の浴用剤は、入浴後のあたたまり感が極めて高く、かつ肌感触が良好であるとともに、保存安定性も良好である。   The bath preparation of the present invention has a very warm feeling after bathing, a good skin feel, and a good storage stability.

本発明の浴用剤は、(A)炭酸ガス発生物を含有する浴用剤組成物と、(B)油性成分を含有する浴用剤組成物の2剤からなるものである。
(A)炭酸ガス発生物を含有する浴用剤組成物において、炭酸ガス発生物は浴用剤組成物(A)を浴湯に投入したとき炭酸ガスを発生させるものであり、酸と炭酸塩とを組み合せたものが好ましい。酸としては、有機酸及び無機酸の何れでも使用できるが、水溶性で固体のものが好ましく、この中でも、例えばコハク酸、フマル酸、リンゴ酸、アジピン酸、酒石酸、安息香酸、クエン酸、ピロリドンカルボン酸、サリチル酸などの有機酸が特に好ましい。無機酸としてはホウ酸、メタケイ酸、無水ケイ酸等が挙げられる。また炭酸塩としては、炭酸ナトリウム、炭酸水素ナトリウム、炭酸マグネシウム、炭酸カリウムなどが好ましい。これらの酸及び炭酸塩はそれぞれから選ばれる1種又は2種以上を混合して用いることができる。
The bath agent of the present invention comprises two agents: (A) a bath agent composition containing a carbon dioxide gas generation product and (B) a bath agent composition containing an oil component.
(A) In the bath agent composition containing a carbon dioxide gas generator, the carbon dioxide generator generates carbon dioxide gas when the bath agent composition (A) is added to the bath water. Combinations are preferred. As the acid, any of organic acids and inorganic acids can be used, but those that are water-soluble and solid are preferable. Among them, succinic acid, fumaric acid, malic acid, adipic acid, tartaric acid, benzoic acid, citric acid, pyrrolidone Organic acids such as carboxylic acid and salicylic acid are particularly preferred. Examples of inorganic acids include boric acid, metasilicic acid, and silicic anhydride. Moreover, as carbonate, sodium carbonate, sodium hydrogencarbonate, magnesium carbonate, potassium carbonate, etc. are preferable. These acids and carbonates can be used alone or in combination of two or more.

酸及び炭酸塩の配合量は特に制限されないが、発生した炭酸ガスを油相だけでなく浴湯中へも分配させる点を考慮すると、酸と炭酸塩の配合割合を適宜選択して浴湯のpHが5〜7(0.01質量%水溶液)となるようにすれば浴湯中の炭酸ガスを溶解した状態で存在せしめることができ、優れた血行促進効果が得られる。より好ましい酸の含有量は、浴用剤組成物(A)中10〜80質量%であり、特に好ましくは15〜50質量%である。また、より好ましい炭酸塩の含有量は、浴用剤組成物(A)中5〜80質量%、特に好ましくは10〜50質量%である。   The mixing amount of the acid and carbonate is not particularly limited, but considering that the generated carbon dioxide gas is distributed not only in the oil phase but also in the bath water, the mixing ratio of the acid and the carbonate is appropriately selected. If the pH is adjusted to 5 to 7 (0.01% by mass aqueous solution), the carbon dioxide gas in the bath water can be dissolved and an excellent blood circulation promoting effect can be obtained. The content of the acid is more preferably 10 to 80% by mass, particularly preferably 15 to 50% by mass in the bath agent composition (A). Moreover, content of more preferable carbonate is 5-80 mass% in a bath agent composition (A), Most preferably, it is 10-50 mass%.

An oily component having a distribution ratio of 1.1 or more is preferred. By containing an oil component having such a distribution ratio, carbon dioxide gas generated when the two-component bath agent of the present invention is added to the bath water is present in a higher concentration in the oil phase as well as in the bath water. become. This makes it possible to supply a higher concentration of carbon dioxide gas to the skin as compared to conventional carbon dioxide gas-containing product bath agents.

〔炭酸ガスの油相/水相への分配の測定方法〕
炭酸ガスの分配操作は以下の方法で行った。油剤2mLとイオン交換水8mLを15mLのスクリュー管に入れ、管底部にノズルを挿入し4分間炭酸ガスを連続注入した。注入停止後、上層に油層が形成されたら速やかに油層を採取し、炭酸ガス測定サンプルとした。次にスクリュー管底部にピペットを静かに挿入して水相を採取し、炭酸ガス測定サンプルとした。
炭酸ガス濃度の測定には、ATR−IR法を用いた。炭酸ガスのIRスペクトルは2350cm-1付近に強い吸収を示すことが知られており、この吸収は振動モードとしては、1つであるが、気体の場合、回転の遷移が重畳するため、分解能の低い設定で測定すると見かけ上、2本の吸収に分裂して観測されるが、炭酸ガスが液体に溶解した場合、回転が制限されるため、1本の吸収帯として観測され、この違いから気体と液体に溶解した炭酸ガスが識別される。
〔測定条件〕
装置:パーキンエルマー SpectrumOne/ユニバーサルATRユニット
分解能:16cm-1
スキャン回数:16回(約25秒)
大気補正機能:OFF
測定順序:油剤バックグラウンド測定→油相の測定→水のバックグラウンド測定→水相の測定
[Measurement method of distribution of carbon dioxide gas to oil phase / water phase]
Carbon dioxide gas was distributed by the following method. 2 mL of oil and 8 mL of ion exchange water were placed in a 15 mL screw tube, a nozzle was inserted into the bottom of the tube, and carbon dioxide gas was continuously injected for 4 minutes. After stopping the injection, when an oil layer was formed in the upper layer, the oil layer was immediately collected and used as a carbon dioxide measurement sample. Next, a pipette was gently inserted into the bottom of the screw tube to collect an aqueous phase, which was used as a carbon dioxide measurement sample.
The ATR-IR method was used for measuring the carbon dioxide concentration. The IR spectrum of carbon dioxide gas is known to exhibit strong absorption near 2350 cm −1 , and this absorption is one vibration mode. When measured at a low setting, it is observed that it splits into two absorptions, but when carbon dioxide dissolves in the liquid, the rotation is limited, so it is observed as one absorption band. And carbon dioxide dissolved in the liquid is identified.
〔Measurement condition〕
Device: PerkinElmer SpectrumOne / Universal ATR unit Resolution: 16cm -1
Number of scans: 16 times (about 25 seconds)
Atmospheric correction function: OFF
Measurement sequence: Oil background measurement → Oil phase measurement → Water background measurement → Water phase measurement

その結果、表1に示すように油剤の種類によって、炭酸ガスの油相/水相分配比が異なる。ここで使用した油剤は、いずれも炭酸ガスの油相/水相分配比が1以上であり、これらはいずれも本発明に使用できる。本発明においては、これらの油剤の2種以上を混合して分配比1.1以上に調整することもできる。   As a result, as shown in Table 1, the oil phase / water phase distribution ratio of carbon dioxide varies depending on the type of oil. The oil agent used here has an oil phase / water phase distribution ratio of carbon dioxide of 1 or more, and any of these can be used in the present invention. In the present invention, two or more of these oil agents can be mixed and adjusted to a distribution ratio of 1.1 or more.

In addition, the one-component bath agent (Comparative Example 4) had a strong feeling of warming but a low storage stability. On the other hand, a bath agent composition comprising a bath agent composition A and a bath agent composition B, which contains an oily component having an oil phase / water phase distribution ratio of carbon dioxide of 1.1 or more, is warm. And storage stability were both good.
