Description

【0001】
【発明の属する技術分野】
本発明は、白濁剤として用いられる造粒物及びその製造方法並びに該造粒物を含有する浴用剤組成物に関する。
【0002】
【従来の技術】
浴用剤における白濁剤としては、一般的に無機顔料が配合されている。しかし、無機顔料をそのまま配合しても浴湯中に分散しないため白濁効果が不十分である。従って、これまでも無機顔料の浴湯中での分散性向上について種々の検討がなされてきており、水溶性高分子で無機顔料を被覆した白濁剤を含有する浴用剤(特開昭63−57516号公報等)、HLB11〜18の界面活性剤でその表面が被覆された無機顔料の造粒物を乳白剤として配合した浴用剤(特開平02−9811号公報)、あるいはアシル化されたNを有するアミノ酸系界面活性剤で被覆された水不溶性で好ましくは白色の無機顔料を含有してなる粉末状の浴用剤(特開平03−240722号公報)、炭酸塩、水不溶性無機顔料粉末とともに多価アルコールを含有することを特徴とする固体状浴用剤(特開平08−325137号公報)等が見出されている。
【0003】
中でも特に、酸化チタンと水溶性高分子を混和し造粒した白濁剤が、安定性、コスト的にも用いられるケースが多かった。
これら特許文献では、無機顔料が水溶性高分子等で被覆したものと表現されているが実際には、無機顔料と水溶性高分子等を水等とともに混和し、それを乾燥させたものであるため、本明細書では造粒物と記載するが、被覆物が同等のものであることはいうまでもない。
【0004】
【発明が解決しようとする課題】
しかし、前述の無機顔料と水溶性高分子の造粒物は、吸湿性が高く、吸湿による固化及び製剤の褐色への変色を起こす等、製剤の安定性に問題があった。従って、これら製剤は防湿性の高いプラスチック容器に保存する必要があり、紙製の容器で保存することはできなかった。現在、環境問題が重要視されており、ゴミの減量化が図られていることから、そのままゴミとなってしまうプラスチック製容器を使用するのではなく紙製容器を用いることが好ましいが、そのためには前記の吸湿による固化を防止する必要性があった。
【0005】
ここで、特開昭63−57516号公報等には、水溶性高分子としてカルボキシメチルセルロースナトリウム(CMCNa)を用いて、これで無機顔料を被覆した白濁剤が示されており、この白濁剤は吸湿による固化、変色を生じないものであった。しかし、このCMCNaで無機顔料を被覆した白濁剤は、水道水中の金属イオン(カルシウムイオン及びマグネシウムイオンなど)の存在により浴湯中の分散性が悪くなるため、水道水、特に硬度の高い地域での水道水にそのまま浴用剤用の白濁剤として適用することは不可能であった。
【0006】
また、特開平02−9811号公報に記載のアナターゼ型酸化チタンを特定の界面活性剤で被覆した造粒物は、界面活性剤を含有することによる浴湯排水の環境上の問題だけでなく、製剤保存時、経時的に白濁溶解性が低下するという問題を有していた。
【0007】
【課題を解決するための手段】
本発明者らは、これらの課題を解決すべく鋭意研究を行った結果、無機顔料としてアナターゼ型の酸化チタンを用いて、これと水溶性高分子を混和し造粒した造粒物を含有する浴用剤組成物は、浴湯中に問題なく溶解し分散し、更に吸湿による固化や変色、或いはアルカリ性製剤中での安定性(吸湿による固化又は変色)について問題を生じることがないことを見出し、本発明を完成させた。
【0008】
即ち、本発明は、以下の発明を包含する。
(1)アナターゼ型酸化チタン及び水溶性高分子を含有する造粒物。
(2)水溶性高分子に対するアナターゼ型酸化チタンの重量比X(アナターゼ型酸化チタン/水溶性高分子)が4≧X≧1である前記(1)に記載の造粒物。
(3)水溶性高分子がゼラチン、アラビアガム、グアーガム、トラガントガム、澱粉、カルボキシメチルセルロース、カルボキシメチルセルロースナトリウム、メチルセルロース、ヒドロキシエチルセルロース、ポリアクリル酸ナトリウム及びポリビニルピロリドンからなる群から選ばれる少なくとも1種である前記(1)又は(2)に記載の造粒物。
(4)界面活性剤を実質的に含有しない前記(1)〜(3)のいずれかに記載の造粒物。
(5)前記(1)〜(4)のいずれかに記載の造粒物を含有する浴用剤組成物。
(6)アナターゼ型酸化チタン及び水溶性高分子を含有し、かつ、界面活性剤を実質的に含有しない固形状浴用剤組成物。
(7)アナターゼ型酸化チタン、水溶性高分子及び水を混合し、乾燥して造粒物とすることを特徴とする、前記(1)〜(4)のいずれかに記載の造粒物の製造方法。
【0009】
【発明の実施の形態】
本発明で用いるアナターゼ型酸化チタンは、例えば「酸化チタン」(清野学 著、技報堂出版 発行、1991年、47〜50頁)に詳細に記載されており、結晶の単位格子ユニットセルあたり、二酸化チタンの化学単位を4個含み、八面体の4稜共有鎖状構造を有している。工業的に用いられる酸化チタンには、結晶構造の違いによりルチル型酸化チタンとアナターゼ型酸化チタンとがあり、一般に浴用剤中に配合される場合は、ルチル型酸化チタンが用いられている。本発明では、アナターゼ型酸化チタンを用いることにより、ルチル型酸化チタンを用いた場合に比べて、浴湯での溶解分散時に水道水中の硬度の影響を受けることなく均一に分散し、白濁効果を有することを見出した。
【0010】
本発明で用いる水溶性高分子としては、例えば、水溶性高分子がゼラチン、アラビアガム、グアーガム、トラガントガム、澱粉、カルボキシメチルセルロース、カルボキシメチルセルロースナトリウム、メチルセルロース、ヒドロキシエチルセルロース、ポリアクリル酸ナトリウム及びポリビニルピロリドンなどが挙げられ、これらを単独で、又は2種以上組み合わせて用いることができる。これら水溶性高分子としては、浴湯への溶解性又は分散性あるいは製剤の安定性の点で、カルボキシメチルセルロースナトリウム、ポリビニルピロリドンが好ましく、カルボキシメチルセルロースナトリウムが更に好ましい。カルボキシメチルセルロースナトリウムとしては、水に溶解するものであれば特に制限はないが、2%水溶液の粘度が200mPa・s以下であるものが好ましく、1〜100mPa・sであるものが更に好ましい。このカルボキシメチルセルロースの2%水溶液の粘度がこの範囲を下回ると、造粒物の分散安定性が悪くなり、この範囲を超えると造粒が困難である。
【0011】
アナターゼ型酸化チタンを用いる本発明の造粒物では、水溶性高分子に対するアナターゼ型酸化チタンの重量比X(アナターゼ型酸化チタン/水溶性高分子)が4≧X≧1での造粒が可能である。前記重量比X(アナターゼ型酸化チタン/水溶性高分子)は、4≧X≧1.5であることが特に好ましい。前記Xの値がこの範囲を下回ると、造粒物の配合量に見合う濁度が得られない。前記Xの値がこの範囲を超えると、水溶性高分子による被覆効果が低下し、浴湯への分散安定性が悪くなる。
【0012】
本発明の造粒物における界面活性剤は、浴湯の環境上の問題や製剤自体の安定性(界面活性剤は、香料などの影響を受けやすく溶解性の低下を招いたり、固結、変色、変臭の原因となる)、コストなどの点で、造粒物中1%以下であることが好ましく、実質的に含有しないことが更に好ましい。
本発明の造粒物は、アナターゼ型酸化チタン、水溶性高分子及び必要に応じてその他の成分を適当量の水とともに混合し、乾燥して造粒物とすることにより製造することができる。
【0013】
アナターゼ型酸化チタン、水溶性高分子及び水等の混合の順序は、特に制限はなく、水に水溶性高分子を加え、必要に応じて加温溶解した後、アナターゼ型酸化チタンを加え混合してもよいし、また、アナターゼ型酸化チタンと水溶性高分子を混合した後、水を加えロール、ニーダーなどの混練機により混合、分散してもよい。造粒に用いられる水と、アナターゼ型酸化チタンと水溶性高分子の総量の比は、10:1〜1:10であることが好ましく、4:1〜1:8であることが更に好ましい。造粒に用いられる水と、酸化チタン及びCMCNaの総量との比がこの範囲を下回ると、均質な造粒が困難となるため造粒物の溶解性が悪くなり、この範囲を超えると水分除去の作業効率が悪くなる。
【0014】
本発明の造粒物の製造方法の一例を以下に示す。
精製水200重量部に前記水溶性高分子を40重量部加え、20〜80℃で0.5〜3.0時間撹拌し溶解させる。これにアナターゼ型酸化チタンを60重量部添加し、常温で10〜15分撹拌し、分散させる。
この分散物を送風定温乾燥器に入れ30〜150℃で10〜30時間乾燥する。次に、これをマイクロバンタムミル、ユニバーサルボール等の粉砕機で60〜200メッシュに粉砕する。以上によって目的とする造粒物を得ることができる。
【0015】
本発明の造粒物は、浴用剤用白濁剤として用いることができる。本発明の造粒物を配合した浴用剤組成物は、紙製容器での充填、保管も可能であり、ゴミの低量化の観点からもメリットが大きい。
また、本浴用剤組成物中の前記造粒物の配合量は、浴湯中の白濁剤の濃度が0.15〜30ppmになるように配合することが好ましく、1.5〜22.5ppmが更に好ましい。造粒物の配合量がこの範囲を下回ると、浴用剤の色調が低下し、この範囲を超えると、浴湯への投入時の溶解性が低下する。
【0016】
本発明の造粒物には、アナターゼ型酸化チタン及び水溶性高分子のほか、必要に応じて、通常浴用剤組成物に配合される各種成分、例えば炭酸塩、有機酸、無機顔料、保湿剤、防腐剤、金属イオン封鎖剤、香料、無機塩類、油性成分、生薬抽出物、植物抽出物、ビタミン類、蛋白分解酵素、冷感剤、温感剤、その他の成分を、本発明の効果を害しない範囲で配合することができる。本発明の造粒物に、これらの任意成分を配合する場合には、アナターゼ型酸化チタンと水溶性高分子の総量に対し、20%以下であることが好ましく、10%以下であることが更に好ましい。
【0017】
更に、本発明の浴用剤組成物中には、前記造粒物のほか、必要に応じて、通常浴用剤組成物に配合される各種成分、例えば炭酸塩、有機酸、無機顔料、保湿剤、防腐剤、金属イオン封鎖剤、香料、無機塩類、油性成分、生薬抽出物、植物抽出物、ビタミン類、蛋白分解酵素、冷感剤、温感剤、その他の成分を、本発明の効果を害しない範囲で配合することができる。この場合、本発明の造粒物以外の浴用剤成分に本発明の造粒物を加え、これを混合機に入れて常温下均一撹拌混合することによって製造される。混合機は、粉体を撹拌、混合するために使用されるものであればどのようなものでも使用できる。具体的にはバートミキサー、ナウターミキサー、万能撹拌混合機、リボンミキサー、V字型混合機等を挙げることができる。混合時間は、成分が均一に混合するのに必要な時間であればよく、前記の例に挙げた混合機を使用する場合には、通常5〜50分間でよい。
【0018】
また、本発明は、アナターゼ型酸化チタン及び水溶性高分子を含有し、かつ、界面活性剤を実質的に含有しない固形状浴用剤組成物を提供する。本発明の固形状浴用剤組成物は、当該浴用剤組成物が固形状、例えば顆粒状、ブリケット状、フレーク状、錠剤状であればよく、必ずしも前記のような造粒物を含有する必要はない。本発明の浴用剤組成物には、アナターゼ型酸化チタン及び水溶性高分子のほか、必要に応じて、通常浴用剤組成物に配合される各種成分、例えば炭酸塩、有機酸、無機顔料、保湿剤、防腐剤、金属イオン封鎖剤、香料、無機塩類、油性成分、生薬抽出物、植物抽出物、ビタミン類、蛋白分解酵素、冷感剤、温感剤、前記の(3)に記載した以外の水溶性高分子、その他の成分を、本発明の効果を害しない範囲で配合することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a granulated product used as a clouding agent, a method for producing the same, and a bath composition containing the granulated product.
[0002]
[Prior art]
As the clouding agent in the bath agent, an inorganic pigment is generally blended. However, even if the inorganic pigment is blended as it is, it does not disperse in the bath water, so that the clouding effect is insufficient. Therefore, various studies have been made on improving the dispersibility of inorganic pigments in bath water, and a bath agent containing a clouding agent coated with an inorganic pigment with a water-soluble polymer (JP-A-63-57516). JP-A-2002-9811), a bath agent in which a granulated product of an inorganic pigment whose surface is coated with a surfactant of HLB 11 to 18 is blended as an opacifying agent (JP-A-02-9811), or an acylated N Powdery bath agent containing a water-insoluble and preferably white inorganic pigment coated with an amino acid-based surfactant (JP-A-03-240722), carbonate, and water-insoluble inorganic pigment powder together with polyvalent A solid bath agent characterized by containing an alcohol (JP-A-08-325137) and the like have been found.
[0003]
Above all, in many cases, a clouding agent obtained by mixing titanium oxide and a water-soluble polymer and granulating is used in terms of stability and cost.
In these patent documents, it is described that the inorganic pigment is coated with a water-soluble polymer or the like, but actually, the inorganic pigment and the water-soluble polymer are mixed with water and the like, and dried. For this reason, in this specification, it is described as a granulated product, but it goes without saying that the coated product is equivalent.
[0004]
[Problems to be solved by the invention]
However, the above-mentioned granulated product of the inorganic pigment and the water-soluble polymer has high hygroscopicity, and has a problem in the stability of the preparation such as solidification due to moisture absorption and discoloration of the preparation to brown. Therefore, these preparations had to be stored in a highly moisture-proof plastic container, and could not be stored in a paper container. At present, environmental issues are regarded as important, and the reduction of garbage is being attempted. Therefore, it is preferable to use a paper container instead of using a plastic container that becomes garbage as it is. It was necessary to prevent the above-mentioned solidification due to moisture absorption.
[0005]
Here, JP-A-63-57516 and the like disclose a clouding agent coated with an inorganic pigment using sodium carboxymethylcellulose (CMCNa) as a water-soluble polymer, and this clouding agent absorbs moisture. Solidification and discoloration did not occur. However, the cloudiness agent coated with an inorganic pigment with CMCNa has poor dispersibility in bath water due to the presence of metal ions (such as calcium ions and magnesium ions) in tap water. It was impossible to apply it as is to a tap water as a clouding agent for a bath agent.
[0006]
Further, granules obtained by coating anatase-type titanium oxide described in JP-A-02-9811 with a specific surfactant are not only environmentally problematic for bath water drainage due to the inclusion of a surfactant, but also At the time of storage of the preparation, there was a problem that the cloudiness solubility decreased with time.
[0007]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to solve these problems, and as a result, using anatase-type titanium oxide as an inorganic pigment, mixing the resultant with a water-soluble polymer and containing a granulated material. The bath agent composition was found to dissolve and disperse in the bath water without any problem, and further did not cause any problem regarding solidification or discoloration due to moisture absorption, or stability in an alkaline preparation (solidification or discoloration due to moisture absorption). The present invention has been completed.
[0008]
That is, the present invention includes the following inventions.
(1) Granules containing anatase-type titanium oxide and a water-soluble polymer.
(2) The granulated product according to (1), wherein the weight ratio X of anatase-type titanium oxide to water-soluble polymer (anatase-type titanium oxide / water-soluble polymer) is 4 ≧ X ≧ 1.

(6) A solid bath agent composition containing anatase-type titanium oxide and a water-soluble polymer, and containing substantially no surfactant.
(7) The granulated product according to any one of (1) to (4), wherein anatase-type titanium oxide, a water-soluble polymer, and water are mixed and dried to obtain a granulated product. Production method.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The anatase type titanium oxide used in the present invention is described in detail in, for example, "Titanium oxide" (manabu Kiyono, published by Gihodo Publishing, 1991, pp. 47-50), and titanium dioxide per unit cell unit cell of the crystal. And has an octahedral four-edge shared chain structure. Titanium oxides used industrially include rutile-type titanium oxide and anatase-type titanium oxide depending on the difference in crystal structure. In general, rutile-type titanium oxide is used when blended in a bath agent. In the present invention, by using anatase-type titanium oxide, as compared with the case of using rutile-type titanium oxide, it is uniformly dispersed without being affected by hardness in tap water at the time of dissolution and dispersion in bath water, and has a cloudy effect. Was found to have.
[0010]
Examples of the water-soluble polymer used in the present invention include gelatin, gum arabic, guar gum, tragacanth gum, starch, carboxymethylcellulose, sodium carboxymethylcellulose, methylcellulose, hydroxyethylcellulose, sodium polyacrylate and polyvinylpyrrolidone. These can be used alone or in combination of two or more. As these water-soluble polymers, sodium carboxymethylcellulose and polyvinylpyrrolidone are preferable, and sodium carboxymethylcellulose is more preferable, in view of solubility or dispersibility in bath water or stability of the preparation. The sodium carboxymethylcellulose is not particularly limited as long as it dissolves in water, but the 2% aqueous solution preferably has a viscosity of 200 mPa · s or less, more preferably 1 to 100 mPa · s. If the viscosity of the 2% aqueous solution of carboxymethylcellulose is below this range, the dispersion stability of the granulated material will be poor, and if it exceeds this range, granulation will be difficult.
[0011]
The granulated product of the present invention using anatase-type titanium oxide can be granulated with a weight ratio of anatase-type titanium oxide to water-soluble polymer X (anatase-type titanium oxide / water-soluble polymer) of 4 ≧ X ≧ 1. It is. The weight ratio X (anatase type titanium oxide / water-soluble polymer) is particularly preferably 4 ≧ X ≧ 1.5. If the value of X falls below this range, turbidity that is commensurate with the amount of the granulated material cannot be obtained. If the value of X exceeds this range, the effect of coating with the water-soluble polymer is reduced, and the dispersion stability in bath water is deteriorated.
[0012]
The surfactant in the granulated product of the present invention may cause environmental problems of bath water or the stability of the preparation itself (the surfactant is susceptible to the effects of fragrances and the like, causing a decrease in solubility, consolidation and discoloration). From the viewpoint of cost, etc., it is preferable that the content is 1% or less in the granulated material, and it is more preferable that it is not substantially contained.
The granulated product of the present invention can be produced by mixing anatase-type titanium oxide, a water-soluble polymer, and other components as necessary with an appropriate amount of water, and drying to form a granulated product.
[0013]
The order of mixing the anatase-type titanium oxide, the water-soluble polymer, and water is not particularly limited, and the water-soluble polymer is added to water, and after heating and dissolving as necessary, the anatase-type titanium oxide is added and mixed. Alternatively, after mixing the anatase type titanium oxide and the water-soluble polymer, water may be added, and the mixture may be mixed and dispersed by a kneader such as a roll or a kneader. The ratio of the water used for granulation, the total amount of the anatase type titanium oxide and the water-soluble polymer is preferably from 10: 1 to 1:10, and more preferably from 4: 1 to 1: 8. If the ratio of the water used for granulation to the total amount of titanium oxide and CMCNa falls below this range, uniform granulation becomes difficult and the solubility of the granulated material deteriorates. Work efficiency becomes worse.
[0014]
An example of the method for producing a granulated product of the present invention is described below.
40 parts by weight of the water-soluble polymer is added to 200 parts by weight of purified water, and the mixture is stirred and dissolved at 20 to 80 ° C. for 0.5 to 3.0 hours. To this is added 60 parts by weight of anatase type titanium oxide, and the mixture is stirred and dispersed at room temperature for 10 to 15 minutes.
The dispersion is placed in a constant-temperature air dryer and dried at 30 to 150 ° C. for 10 to 30 hours. Next, this is pulverized to 60 to 200 mesh using a pulverizer such as a micro bantam mill or a universal ball. Thus, the desired granulated product can be obtained.
[0015]
The granulated product of the present invention can be used as a clouding agent for a bath agent. The bath agent composition containing the granules of the present invention can be filled and stored in a paper container, and has a great advantage from the viewpoint of reducing the amount of dust.
The amount of the granules in the bath composition is preferably such that the concentration of the clouding agent in the bath is 0.15 to 30 ppm, and 1.5 to 22.5 ppm is preferable. More preferred. If the amount of the granulated material falls below this range, the color tone of the bath agent will decrease, and if it exceeds this range, the solubility when charged into bath water will decrease.
[0016]
