Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for preventing discoloration of a hair grower comprising minoxidil formulated therein with which there is a solution to problems that contents cannot be judged though the discoloration can be suppressed to some extent by using a material completely screening light as a container for the hair grower comprising the minoxidil formulated therein, on the other hand, it is difficult to prevent the discoloration with time because a transparent material such as a glass container has low light screening properties, etc. <P>SOLUTION: The method for preventing the discoloration of the hair grower comprising the minoxidil formulated therein is carried out as follows. The container composed of a plastic substantially made of polyethylene terephthalate is filled with the hair grower. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、ミノキシジルを配合した育毛剤の着色防止方法に関する。   The present invention relates to a method for preventing coloring of a hair restorer containing minoxidil.

ミノキシジルは、化学名を6−(1−ピペリジニル)−2,4−ピリジンジアミン−3−オキサイドと称し、育毛剤としての適用が記載されている(特許文献1参照)。   Minoxidil has a chemical name of 6- (1-piperidinyl) -2,4-pyridinediamine-3-oxide, and its application as a hair restorer is described (see Patent Document 1).

ミノキシジルを配合した育毛剤は、世界的に使用され脱毛症の治療に用いられている。しかし、外国の製品は、経時的に製剤が黄色に変色する欠点があり、使用時に衣類の汚れや使用感の低下など製品価値を低下させる場合があった。ミノキシジル配合の育毛剤容器の材質としてはPE(ポリエチレン)が用いられているが、経時着色するので好ましい材質の容器とは言い難い。   Hair restorers containing minoxidil are used worldwide to treat alopecia. However, foreign products have the disadvantage that the formulation turns yellow over time, and there are cases where the product value is reduced during use, such as dirt on clothes and a decrease in feeling of use. Although PE (polyethylene) is used as the material for the hair-growth container containing minoxidil, it is difficult to say that it is a preferable material because it is colored over time.

ポリエチレンテレフタレート製プラスチック(PET)は、透明性がよく、強度的にもすぐれているうえ、気体や水分等の遮断性があり、耐熱性がある。コーラ飲料容器、炭酸飲料、しょうゆなどの大型ボトルに広く使われている。   Polyethylene terephthalate plastic (PET) has good transparency and strength, and has a barrier property against gases and moisture, and has heat resistance. Widely used in large bottles such as cola drink containers, carbonated drinks and soy sauce.

米国特許公報第4139619号U.S. Pat. No. 4,139,619

本発明の目的は、ミノキシジルを配合した育毛剤の経時的な着色を防止する方法を提供することにある。   An object of the present invention is to provide a method for preventing coloration over time of a hair restorer containing minoxidil.

本発明者らは、ある種の材質の容器を用いれば製剤の経時的な着色を防ぐことができることを見出し、本発明を完成した。   The present inventors have found that the use of a container made of a certain kind of material can prevent the coloration of the preparation over time, thereby completing the present invention.

すなわち、本発明は、実質的にポリエチレンテレフタレート製プラスチックで構成される容器に封入することを特徴とする、ミノキシジル配合育毛剤の着色防止方法である。   That is, the present invention is a method for preventing coloring of a minoxidil-containing hair restorer, characterized by being enclosed in a container substantially made of polyethylene terephthalate plastic.

後の試験例記載の通り、ポリエチレンテレフタレート製容器に充填した場合、ミノキシジルを配合した育毛剤の経時的な着色を防ぐことが可能になった。一方、従来使われていたポリエチレンまたはポリプロピレン製の容器では着色防止効果は不十分であった。   As described later in the test examples, when a polyethylene terephthalate container was filled, it became possible to prevent coloring of the hair restorer containing minoxidil over time. On the other hand, the conventionally used containers made of polyethylene or polypropylene have an insufficient anti-coloring effect.

本発明で使用する容器の材質は、テレフタル酸またはそのジメチルエステルとエチレングリコールを出発原料とする重合成分を50%以上含む基ポリマーを主成分とするポリエチレンテレフタレート製プラスチック(PET)である。   The material of the container used in the present invention is polyethylene terephthalate plastic (PET) whose main component is a base polymer containing 50% or more of a polymerization component starting from terephthalic acid or its dimethyl ester and ethylene glycol.

本発明で使用する容器は、食品、添加物等の規格基準、乳等省令、米国のFDA規格(21CFR)で規格されている程度のものであればよい。その他のポリエステルなどのプラスチックを発明の効果を損なわない程度配合することもでき、実質的にPET(ポリエチレンテレフタレート)であればよい。   The container used in the present invention may be of a level that is standardized by standard standards for foods, additives, etc., ministerial ordinances such as milk, and US FDA standards (21 CFR). Other plastics such as polyester can be blended to such an extent that the effects of the invention are not impaired, and may be substantially PET (polyethylene terephthalate).

ミノキシジルは薬理活性が高く、十分な育毛剤効果を得るために、1日の投与量を正確にする必要があり、定量注出型の容器は必要になっている。この定量注出型容器本体の材質としても、PET(ポリエチレンテレフタレート)が好ましいが、特にアプリケーター部分の材質に関して、計量部分がポリエチレン、ポリプロピレン、ポリアセタール、ポリメチルペンテンから選ばれ、塗布部分がジメチルシリコン、および容器内に浸漬するチューブがポリエチレンで構成される容器が硬度の面から好ましい。   Minoxidil has high pharmacological activity, and in order to obtain a sufficient hair restorer effect, it is necessary to make the daily dose accurate, and a quantitative dispensing type container is necessary. PET (polyethylene terephthalate) is also preferable as the material of the quantitative pouring type container main body, but particularly the material of the applicator part is selected from polyethylene, polypropylene, polyacetal, polymethylpentene, and the application part is dimethylsilicone. A container in which the tube immersed in the container is made of polyethylene is preferable from the viewpoint of hardness.

さらに1回使い捨てタイプのユニットドーズ容器では、一般に成形しやすく、スクイズ性に優れるポリエチレンが材質に用いられているが、ミノキシジル製剤では経時着色や、製剤中の溶媒の揮散が著しいという問題があった。   Furthermore, in single-use type unit dose containers, polyethylene that is generally easy to mold and has excellent squeeze properties is used as the material. However, in the case of minoxidil preparations, there was a problem that coloring with time and volatilization of the solvent in the preparations were significant. .

しかし、上記PET(ポリエチレンテレフタレート)を用いれば着色および溶媒の揮散の何れも防ぐことができる。   However, if PET (polyethylene terephthalate) is used, both coloring and solvent evaporation can be prevented.

本発明は、育毛剤として用いられる通常の剤型、例えばローション剤、乳液、懸濁剤、トニック剤、クリーム剤、軟膏剤などの製剤で着色防止効果を得ることができる。   The present invention can obtain an anti-coloring effect in a conventional dosage form used as a hair restorer, such as a lotion, emulsion, suspension, tonic, cream, ointment and the like.

製剤の成分としてはミノキシジル以外にも、本発明の効果を損なわない限り、塩酸ジフェンヒドラミン、塩酸イソペンジル等の抗ヒスタミン剤、グリチルレチン酸、グアイアズレン等の抗炎症剤、尿素、サリチル酸等の角質溶解剤、グルコン酸クロルヘキシジン、イソプロピルメチルフェノール、第4級アンモニウム塩、ヒノキチオール、ピロクトンオラミン等の殺菌剤、ヒアルロン酸ナトリム、グリセリン、コンドロイチン硫酸等の保湿剤、イチイ、ボタンピ、カンゾウ、オトリギソウ、附子、ビワ、カワラヨモギ、コンフリー、アシタバ、サフラン、サンシン、ローズマリー、セージ、モッコウ、セイモッコウ、ホップ、プラセンタ等の動植物の抽出物、酢酸レチノール、塩酸ピリドキシン、アスコルビン酸、硝酸チアミン、シアノコバラミン、ビオチン、酢酸トコフェロール等のビタミン類、スクワラン、流動パラフィン、レシチン等の油分、ポリオキシエチレン硬化ヒマシ油等の界面活性剤、メントール、カンフル等の精油成分、ジブチルヒドロキシトルエン、イソプロピルガレート等の抗酸化剤、エチレンジアミンテトラアセテートまたはその塩等の金属イオン封鎖剤、色素、香料等を配合することができる。   In addition to minoxidil, the components of the preparation are antihistamines such as diphenhydramine hydrochloride and isopentyl hydrochloride, anti-inflammatory agents such as glycyrrhetinic acid and guaiazulene, keratolytic agents such as urea and salicylic acid, and chlorhexidine gluconate, as long as the effects of the present invention are not impaired. , Isopropyl methylphenol, quaternary ammonium salt, hinokitiol, piroctone olamine, etc., moisturizers such as sodium hyaluronate, glycerin, chondroitin sulfate, yew, button pi, licorice, hygiensis, appendix, loquat, kawara mugi Free, ashitaba, saffron, sancin, rosemary, sage, mokko, seimokko, hops, placenta and other animal and plant extracts, retinol acetate, pyridoxine hydrochloride, ascorbic acid, thiamine nitrate, cyanocoba Minerals, biotin, vitamins such as tocopherol acetate, oils such as squalane, liquid paraffin, lecithin, surfactants such as polyoxyethylene hydrogenated castor oil, essential oil components such as menthol and camphor, and antibacterials such as dibutylhydroxytoluene and isopropyl gallate An oxidant, a sequestering agent such as ethylenediaminetetraacetate or a salt thereof, a dye, and a fragrance can be blended.
