Abstract
Description
本発明は粒状浴用剤、特に粒状発泡性浴用剤に関する。 The present invention relates to a granular bath agent, and more particularly to a granular foaming bath agent.
炭酸塩と有機酸を配合した浴用剤は、浴水中で炭酸ガスの泡を発生し、当該炭酸ガスによる血行促進効果が得られることから、優れた浴用剤として広く知られている。このような浴用剤においては、浴水中で発生した炭酸ガスの濃度を高める手段として、浴槽の底部付近で浴用剤を溶解させるために、その形態を粒状ではなく、比較的大型の錠剤型とすることが多い。 A bath agent containing a carbonate and an organic acid is widely known as an excellent bath agent because it generates bubbles of carbon dioxide gas in the bath water and the blood circulation promoting effect by the carbon dioxide gas is obtained. In such a bath preparation, as a means for increasing the concentration of carbon dioxide gas generated in the bath water, in order to dissolve the bath preparation in the vicinity of the bottom of the bathtub, the form is not granular but a relatively large tablet type. There are many cases.
一方、浴用剤の他の形態である粒状発泡性浴用剤は、打錠技術等の特殊な製造技術を必要としないこと、一般に溶解時間が短いこと等から、使用状態や好みにより錠剤と使い分けられており、種々の研究がなされている。例えば、炭酸塩や有機酸の粒子径を制御することにより短時間に炭酸ガスを溶解させようとする技術（特許文献１〜３）や、炭酸塩を水溶性高分子で被覆する技術（特許文献４）等が報告されている。しかしながら、これらの浴用剤では泡の性状については何ら検討がなされていない。 On the other hand, granular foaming bath agent, which is another form of bath agent, does not require special manufacturing technology such as tableting technology and generally has a short dissolution time. Various studies have been conducted. For example, a technique for dissolving carbon dioxide gas in a short time by controlling the particle diameter of carbonate or organic acid (Patent Documents 1 to 3), or a technique for coating carbonate with a water-soluble polymer (Patent Document) 4) etc. have been reported. However, these bath preparations have not been studied at all for the properties of foam.
また、発泡する泡を細かくして温浴効果を高める技術として浴水中での溶解パターンが異なる２種以上の炭酸塩と有機酸を含有し、その炭酸塩の少なくとも１種が浴槽底部まで実質的に溶けずに沈降する炭酸塩である粒状発泡入浴剤（特許文献５）が報告されている。 In addition, as a technique for increasing the effect of warm bath by reducing foaming bubbles, it contains two or more carbonates and organic acids having different dissolution patterns in bath water, and at least one of the carbonates substantially reaches the bottom of the bathtub. A granular foam bathing agent (Patent Document 5), which is a carbonate that settles without dissolving, has been reported.
しかしながら、この粒状発泡入浴剤では溶解時間を短くすることを目標としているため十分に長い間極めて微細な炭酸ガスの泡が得られるという点については、検討の余地があった。
従って、本発明の課題は、浴水が泡で白く濁ったような外観を呈するほどに極めて微細な炭酸ガスの泡を十分に長い時間維持できるため浴水外観が極めて優れるのみならず十分に高い炭酸ガス濃度が得られ、かつ溶解残り等の欠点がない粒状発泡性浴用剤を提供することにある。
However, since this granular foaming bath has a goal of shortening the dissolution time, there is room for investigation in that extremely fine carbon dioxide bubbles can be obtained for a sufficiently long time.
Therefore, the problem of the present invention is that the bath water appearance is not only excellent, but also sufficiently high, since the extremely fine carbon dioxide bubbles can be maintained for a sufficiently long time so that the bath water appears white and cloudy. An object of the present invention is to provide a granular foaming bath agent capable of obtaining a carbon dioxide concentration and having no disadvantages such as dissolution residue.
そこで本発明者は、上記課題を解決すべく、炭酸塩と有機酸により発生する炭酸ガスの泡を浴水中に保持するための技術を種々検討した結果、炭酸塩として炭酸ジアルカリ金属塩を主成分とし、また有機酸として酒石酸、又は酒石酸及びリンゴ酸をそれぞれ独立した粒子状態で浴水に投入すると、全く意外にも浴水中で発生する炭酸ガスの泡が極めて微細なものになること、さらにはその極めて微細な泡の発生時間を長く維持でき、浴槽全体が泡で白く濁ったような外観を呈すことから、浴水の外観上も良好な粒状発泡性浴用剤が得られるとともに、十分に高い炭酸ガス濃度が得られることを見出した。 Therefore, in order to solve the above-mentioned problems, the present inventors have studied various techniques for holding carbon dioxide bubbles generated by carbonate and organic acid in bath water. As a result, the present inventors have mainly used a dialkali metal carbonate as a carbonate. In addition, when tartaric acid or tartaric acid and malic acid are added as organic acids to the bath water in an independent particle state, the bubbles of carbon dioxide gas generated in the bath water are unexpectedly extremely fine, and The generation time of the very fine bubbles can be maintained for a long time, and the entire bath tub appears to be white and cloudy, so that it is possible to obtain a granular foaming bath agent with good bath water appearance and sufficiently high. It has been found that a carbon dioxide concentration can be obtained.
すなわち、本発明は、炭酸塩及び有機酸を含有する粒状発泡性浴用剤であって、
次の成分（Ａ）及び（Ｂ）：
（Ａ）平均粒子径が１００〜７５０μｍの炭酸ジアルカリ金属塩 ２０〜７０質量％、及び
（Ｂ）酒石酸、又は酒石酸及びリンゴ酸 ３０〜８０質量％を含有し、
炭酸塩全量中の炭酸ジアルカリ金属塩量が７５〜１００質量％である粒状発泡性浴用剤を提供するものである。
なお、本発明の粒状発泡性浴用剤は、（Ａ）及び（Ｂ）成分がそれぞれ独立の粒子状態で存在するものである。ここで「独立の粒子状態で存在する」とは、それぞれ独立した粒子状態の（Ａ）成分及び（Ｂ）成分が浴用剤中に混在していることを意味するものであり、一般的に粉状や顆粒状と呼ばれるものも含む。なお、これは炭酸塩粒子、有機酸粒子及びその他の粒子をコーティングや造粒等せずにそのまま混合したものや、個々の成分を個別に適宜コーティング又は造粒した後混合したものや、個々の成分の一部又は全部を混合した後適宜コーティング又は造粒し更に残りの成分と混合したものを含む。
That is, the present invention is a granular foaming bath agent containing a carbonate and an organic acid,
The following components (A) and (B):
(A) 20 to 70% by mass of a dialkali metal carbonate having an average particle size of 100 to 750 μm, and (B) tartaric acid, or 30 to 80% by mass of tartaric acid and malic acid,
A granular foaming bath agent in which the amount of dialkali metal carbonate in the total amount of carbonate is 75 to 100% by mass is provided.
In the granular foaming bath agent of the present invention, the components (A) and (B) are present in independent particle states. Here, “existing in an independent particle state” means that the component (A) and the component (B), which are in an independent particle state, are mixed in the bath preparation. It also includes what are called shapes and granules. In addition, this is a mixture of carbonate particles, organic acid particles and other particles as they are without coating or granulation, etc., or those obtained by individually coating or granulating individual components and mixing them. It includes a mixture of some or all of the components, followed by appropriate coating or granulation and further mixing with the remaining components.
本発明の粒状発泡性浴用剤を浴水に投入すると、浴槽全体が泡で白く濁ったような外観を呈するほどに極めて微細な泡が発生し、かつその発泡の持続時間は十分に長い。従って、発生した炭酸ガスが十分に浴水中に溶解するため、炭酸ガスの浴水中への溶解量、血行促進効果、温まり感に有利な影響がもたらされるとともに、極めて微細な泡による白く濁った外観により浴用剤投入直後から快適な浴用感が得られる。また、白濁剤として油剤や界面活性剤、無機粉体等の添加を要することなく、白濁状の浴用効果が得られる。すなわち、白濁状の浴用効果が得られるにもかかわらず、その白濁が炭酸ガスによるものであることから、浴槽を汚すことがない。 When the granular foaming bath agent of the present invention is added to bath water, extremely fine bubbles are generated so that the entire bath looks white and cloudy, and the duration of foaming is sufficiently long. Therefore, since the generated carbon dioxide is sufficiently dissolved in the bath water, it has an advantageous effect on the amount of carbon dioxide dissolved in the bath water, blood circulation promotion effect, warmth feeling, and white and cloudy appearance due to extremely fine bubbles Thus, a comfortable bath feeling can be obtained immediately after the bath agent is added. Further, a white turbid bath effect can be obtained without adding an oil agent, a surfactant, an inorganic powder or the like as a white turbid agent. That is, although the white turbid bathing effect is obtained, the white turbidity is caused by carbon dioxide gas, so that the bathtub is not soiled.
本発明の粒状発泡性浴用剤は、発生する炭酸ガスの泡を白く濁ったような外観を呈するほど微細化する点から、（Ａ）炭酸ジアルカリ金属塩を浴用剤中に２０〜７０質量％含有する。なお、炭酸ジアルカリ金属塩とは、炭酸塩のうちアルカリ金属を２個有する炭酸塩であり、例えば、炭酸ナトリウム、炭酸カリウムが挙げられるが、炭酸ナトリウム（Ｎａ2ＣＯ3）が特に好ましい。 The granular foamable bathing agent of the present invention contains (A) a dialkali metal carbonate in an amount of 20 to 70% by mass in the bathing agent from the point that the generated carbon dioxide bubbles are so fine that they appear white and cloudy. To do. The dialkali metal carbonate is a carbonate having two alkali metals among carbonates, and examples thereof include sodium carbonate and potassium carbonate, with sodium carbonate (Na 2 CO 3 ) being particularly preferred.
また、炭酸ジアルカリ金属塩の浴用剤中の含有量は、炭酸ガス発生量及び浴槽全体が泡で白く濁ったような外観を呈するほどに微細な泡を得る点から、さらに３０〜６０質量％、特に３５〜５０質量％が好ましい。本発明の粒状発泡性浴用剤は炭酸ジアルカリ金属塩以外の炭酸塩、例えば、炭酸水素塩である炭酸水素ナトリウム（重曹）や二価の金属の炭酸塩等を含有しても良いが、微細な泡を発生させる点で、炭酸塩全量中の炭酸ジアルカリ金属塩量は、７５〜１００質量％であり、さらに８０〜１００質量％、特に８５〜１００質量％であることが好ましい。特に、炭酸塩中の炭酸水素塩量が多くなると、大きな泡になってしまう傾向がある。このため、炭酸ガスの大きな泡の発生を抑制し、白濁状を呈するような微細な泡とするため、炭酸塩全量中の炭酸水素ナトリウム量は、１０質量％未満、さらに５質量％未満、特に炭酸水素ナトリウムを実質的に含まないことが好ましい。 In addition, the content of the dialkali metal carbonate salt in the bath preparation is 30 to 60% by mass, from the point of obtaining carbon dioxide generation amount and fine bubbles so that the whole bath looks white and cloudy. 35-50 mass% is especially preferable. The granular foaming bath agent of the present invention may contain a carbonate other than the dialkali metal carbonate, for example, sodium bicarbonate (bicarbonate) which is a bicarbonate, a divalent metal carbonate, etc. In terms of generating bubbles, the amount of dialkali metal carbonate in the total amount of carbonate is 75 to 100% by mass, more preferably 80 to 100% by mass, and particularly preferably 85 to 100% by mass. In particular, when the amount of hydrogen carbonate in the carbonate increases, there is a tendency to form large bubbles. For this reason, in order to suppress generation | occurrence | production of the big bubble of a carbon dioxide gas and to make it a fine bubble which exhibits a cloudy state, the amount of sodium hydrogen carbonate in the carbonate whole quantity is less than 10 mass%, Furthermore, less than 5 mass%, especially It is preferable that it does not contain sodium hydrogencarbonate substantially.
炭酸ジアルカリ金属塩の平均粒子径は、泡の微細化、泡の持続時間、沈降性等の点から、１００〜７５０μｍ、さらに２００〜６００μｍ、特に２５０〜５００μｍであるのが好ましい。平均粒子径は、以下のように測定される。

The average particle diameter of the dialkali metal carbonate is preferably from 100 to 750 μm, more preferably from 200 to 600 μm, particularly preferably from 250 to 500 μm, from the viewpoints of finer foam, duration of foam, sedimentation and the like.

Shaker: Sieve shaker Ro-TAP SHAKER DB type (HEIKO SEISAKUSHO)
Method: Place 50 g of sample on a 2000 μm sieve and classify with a sieve shaker for 5 minutes. The mass of the particles remaining on each sieve and the receiver is measured, and the mass ratio (%) of the particles on each sieve is calculated. The mass ratio of the particles on the sieve with a small opening is accumulated in order from the receiver, and the particle diameter at which the total becomes 50% is defined as the average particle diameter.
本発明の粒状発泡性浴用剤においては、特定の炭酸塩を用いることに加えて、有機酸として酒石酸、又は酒石酸及びリンゴ酸を配合することが、炭酸ガスの泡を浴水全体が白濁を呈する程度に微細化する点から重要である。なお、本発明の粒状発泡性浴用剤において酒石酸及びリンゴ酸の質量比は、微細な泡を得る点、微細な泡の持続性の点及び保存安定性等の点から１００：０〜１：９９、更に１００：０〜８０：２０、特に１００：０〜５０：５０であると好ましい。一方、一般的な発泡性浴用剤では炭酸塩と組み合せることのできる有機酸としてコハク酸やフマル酸等が広く使用されているが、これらの有機酸では十分に微細な泡が得られない。従って、本発明の粒状発泡性浴用剤は酒石酸とリンゴ酸以外の有機酸は実質的に含有しない。本発明の粒状発泡性浴用剤において酒石酸とリンゴ酸以外の有機酸の含有量は５質量％未満である。或いは酒石酸とリンゴ酸以外の有機酸を含有しない。このことによって、十分に微細な泡が得られる。 In the granular foamable bath agent of the present invention, in addition to using a specific carbonate, blending tartaric acid or tartaric acid and malic acid as an organic acid makes the entire bath water cloudy with bubbles of carbon dioxide gas. This is important in terms of miniaturization. In the granular foaming bath agent of the present invention, the mass ratio of tartaric acid and malic acid is 100: 0 to 1:99 from the viewpoint of obtaining fine bubbles, the sustainability of fine bubbles and the storage stability. Further, 100: 0 to 80:20, particularly 100: 0 to 50:50 is preferable. On the other hand, in general foaming bath agents, succinic acid, fumaric acid, and the like are widely used as organic acids that can be combined with carbonates, but these organic acids cannot provide sufficiently fine bubbles. Therefore, the granular foaming bath agent of the present invention contains substantially no organic acid other than tartaric acid and malic acid. In the granular foamable bath agent of the present invention, the content of organic acids other than tartaric acid and malic acid is less than 5% by mass. Or it does not contain organic acids other than tartaric acid and malic acid. As a result, sufficiently fine bubbles can be obtained.

酒石酸、又は酒石酸及びリンゴ酸の平均粒子径は泡の微細化、泡の持続時間、沈降性の点から１００〜１０００μｍ、さらに１２０〜８００μｍ、特に１５０〜７００μｍが好ましい。なお、平均粒子径は、炭酸塩と同じ方法にて測定された値である。 The average particle diameter of tartaric acid or tartaric acid and malic acid is preferably 100 to 1000 μm, more preferably 120 to 800 μm, and particularly preferably 150 to 700 μm from the viewpoints of finer foam, duration of foam, and sedimentation. In addition, an average particle diameter is the value measured by the same method as carbonate.

The granular bath agent of the present invention is preferably used by dissolving in bath water and generating bubbles of carbon dioxide gas. The bath preparation of the present invention can be used as a partial bath such as foot bath and arm bath as well as full body bath such as bath.
本発明の粒状浴用剤は、浴水中に溶解した際に極めて微細な泡が大量に発生し、かつその泡が持続する。微細な泡の発生は、浴水１５０リットル中に４０〜６０ｇの浴用剤を溶解した際に、発生した泡により浴水が白濁状を呈することから確認できる。
また、ここで発生する泡の粒子径は、泡が動くので正確な測定は困難であるが、ビデオ撮影により解析したところ概ね２０〜１００μｍであった。泡の大きさは、発生した泡を含む溶液を、対流のない大きさのガラスセル（１ｍｍ×５ｍｍ×１０ｍｍ）に閉じ込め、目盛りの付いたスライドガラスと共にビデオ顕微鏡を用いて撮影を行い、得られた画像から測定できる。
The granular bath agent of the present invention generates a large amount of extremely fine bubbles when dissolved in bath water, and the bubbles persist. The generation of fine bubbles can be confirmed from the fact that the bath water becomes cloudy due to the generated bubbles when 40 to 60 g of bathing agent is dissolved in 150 liters of bath water.
Further, the particle size of the bubbles generated here is difficult to measure accurately because the bubbles move, but it was approximately 20 to 100 μm when analyzed by video shooting. The size of the bubbles is obtained by confining the solution containing the generated bubbles in a glass cell (1 mm x 5 mm x 10 mm) with no convection and shooting with a slide glass with a scale using a video microscope. It can be measured from the image.
表１に示す配合で各成分を混合し、粉状発泡性浴用剤を製造した。得られた浴用剤について、浴水に溶解した際の泡状態（大きさ、持続時間）、使用感を評価し、結果を合わせて表１に示す。 Each component was mixed by the mixing | blending shown in Table 1, and the powdery foamable bath agent was manufactured. About the obtained bath preparation, the foamed state (size, duration) and usability when dissolved in bath water were evaluated, and the results are shown in Table 1.
〔評価方法〕
（１）発泡の持続時間及び泡の大きさ
直径１５０ｍｍ、高さ５００ｍｍのアクリル製円筒に４０℃の湯６Ｌを入れ、浴用剤１０ｇを投入し、直径６５ｍｍの攪拌羽根をシャフトにつけた攪拌機によって毎分２０回転で攪拌しながら均一に溶解させ、浴用剤が発泡しながら溶解する様子を円筒から３０ｃｍ離れた位置から目視にて観察した。
さらに、円筒の底から３００ｍｍの位置に記した直径１６ｍｍの大きさの円形の印が見えるまでの時間を発泡の持続時間として評価した。
また、泡の大きさは、浴用剤を投入してから１分後の溶液を、対流のない大きさのガラスセル（１ｍｍ×５ｍｍ×１０ｍｍ）に閉じ込め、目盛りの付いたスライドガラスと共にビデオ顕微鏡を用いて撮影を行い、以下の基準で評価した。
大：泡の大きさが１ｍｍ以上
中：泡の大きさが１００μｍ以上、１ｍｍ未満
小：泡の大きさが１００μｍ未満
（２）使用感
浴用剤４０ｇを１５０リットルの浴水に投入してから１分後の濁り状態及び泡が消失した時点での浴用剤の溶け残りなどによる浴槽底面でのざらつきの有無及び白濁の様子を確認した。
〔Evaluation methods〕
(1) Duration of foaming and foam size 6 L of 40 ° C. hot water is placed in an acrylic cylinder having a diameter of 150 mm and a height of 500 mm, 10 g of bathing agent is added, and a stirrer having a 65 mm diameter stirring blade attached to the shaft. The solution was dissolved uniformly while stirring at 20 rpm, and the appearance of the bath agent dissolving while foaming was visually observed from a position 30 cm away from the cylinder.
Furthermore, the time until a circular mark having a diameter of 16 mm marked at a position of 300 mm from the bottom of the cylinder was seen was evaluated as the duration of foaming.
The bubble size was determined by confining the solution 1 minute after adding the bath preparation in a glass cell (1 mm x 5 mm x 10 mm) with no convection. Images were taken and evaluated according to the following criteria.
Large: Foam size is 1 mm or more Medium: Foam size is 100 μm or more and less than 1 mm Small: Foam size is less than 100 μm (2) Feeling of use After adding 40 g of bath agent to 150 liters of bath water, 1 The turbid state after the minute and the presence or absence of roughness on the bottom of the bathtub due to the remaining undissolved bathing agent when the foam disappeared and the state of cloudiness were confirmed.
表１から明らかなように、本発明の粒状発泡性浴用剤はいずれも浴槽全体が白濁するほどの微細な泡の発生時間を長く維持でき、浴槽の底のざらつきもなく使用感が良好であった。また、長期間保管後も包装袋が膨張したり重量が変化する等の事象が起こらず、保存安定性も良好であった。
炭酸ジアルカリ金属塩の含有量の多い比較例１は、炭酸ジアルカリ金属塩が溶け残って浴水の底でざらつきが生じるとともに、泡の量も少なくほとんど白濁しなかった。酒石酸の含有量の多い比較例２は、酒石酸が溶け残って浴槽の底でざらつきが生じるとともに、泡の量も少なくほとんど白濁しなかった。炭酸ジアルカリ金属塩の一部を炭酸水素ナトリウムに置き換えた比較例３や炭酸ジアルカリ金属塩を全部炭酸水素ナトリウムに置き換えた比較例４は、発生した泡が錠剤型浴用剤の泡と比較すると小さいものの浴水全体が白濁を呈するほどではなく（２００μｍ〜２０００μｍ程度）、この大きめの泡のためほとんど白濁しなかった。また泡の持続時間も短かった。酒石酸及びリンゴ酸以外の有機酸(フマル酸)を用いた比較例５は、フマル酸が溶け残って浴槽の底でざらつきが生じるとともに、泡の大きさが大きいためほとんど白濁せず、泡の持続時間も十分でなかった。平均粒子径が１００μｍ未満の炭酸ジアルカリ金属塩を用いた比較例６は、浴水の表面で発泡してしまい、白濁も薄く発泡の持続時間も短いものであった。
As is apparent from Table 1, the granular foaming bath agent of the present invention can maintain the generation time of fine bubbles so that the entire bath becomes cloudy for a long time, and has a good feeling of use without roughness of the bottom of the bath. It was. Moreover, even after long-term storage, the packaging bag did not swell or the weight changed, and the storage stability was good.
In Comparative Example 1 in which the content of the dialkali metal carbonate was high, the dialkali metal carbonate remained undissolved and roughened at the bottom of the bath water, and the amount of foam was small and almost no cloudy. In Comparative Example 2 having a high tartaric acid content, tartaric acid remained undissolved and roughened at the bottom of the bathtub, and the amount of foam was small and almost no cloudy. Comparative Example 3 in which part of the dialkali metal carbonate was replaced with sodium bicarbonate and Comparative Example 4 in which the dialkali metal carbonate was entirely replaced with sodium bicarbonate had small foams compared to the foam of the tablet bath. The entire bath water was not so cloudy (about 200 μm to 2000 μm), and was almost cloudy because of the large bubbles. Also, the bubble duration was short. In Comparative Example 5 using an organic acid (fumaric acid) other than tartaric acid and malic acid, fumaric acid remains undissolved and roughening occurs at the bottom of the bathtub. The time was not enough. In Comparative Example 6 using a dialkali metal carbonate having an average particle size of less than 100 μm, foaming occurred on the surface of the bath water, resulting in a short cloudiness and a short foaming duration.
