Description

【0001】
【発明の属する技術分野】
本発明は、噴出物をシャーベット状に凝固させることにより冷却効果を高めたエアゾール剤に関する。
【0002】
【従来の技術】
従来、打撲、捻挫、筋肉疲労などの痛みや、水虫、虫刺されなどによる痒みを和らげるにはゲル剤やエアゾール剤などを用いるのが一般的であった。しかし、ゲル剤は即効性が弱く、一般的に用いられるエアゾール剤は持続的な効果がなかった。
【0003】
一般的に患部の痛み、かゆみを鎮めるためには、患部を冷却することが有効である。そのため、持続的な冷却効果を有するエアゾール剤としてWO90/11068号公報明細書、特開平4−103526号公報などには噴出物がシャーベット状の泡沫ゲルを形成するエアゾール剤が開示されている。しかし、それらのエアゾール剤は、製造工程が煩雑であり、また、それらはエアゾール剤の原液に水を配合することが必須であることから水に不安定な薬剤や、親油性の高い薬剤は配合が困難であった。さらに、それらのエアゾール剤は使用感の点で満足できなかった。
【0004】
【発明が解決しようとする課題】
本発明の目的は従来の技術の不都合な点を解決し、噴射塗布したときに、強力で持続的な皮膚冷却性を有するエアゾール剤を提供することにある。
【0005】
【課題を解決するための手段】
本発明者らは、上記目的を達成するため種々検討した結果、低級アルコール、直鎖モノカルボン酸および液化ガスを配合したエアゾール剤は、噴出物がシャーベット状に凝固することにより持続的な冷却効果を有し、さらに使用感も極めて優れていることを見出し、本発明を完成した。
【0006】
すなわち本発明は炭素原子数1〜3の低級アルコールおよび炭素原子数10〜22の直鎖モノカルボン酸を含む原液ならびに液化ガスからなる、噴出物が塗布部位でシャーベット状に凝固する皮膚冷却用エアゾール剤である。従来、製剤中に直鎖モノカルボン酸を配合することにより冷却効果を発現する皮膚冷却用エアゾール剤は知られていなかった。
【0007】
従来知られている持続的な皮膚冷却効果を有するエアゾール剤は、そのいずれも配合する水が凍ることにより噴出物を凝固させ冷却効果を持続させるが、本発明のエアゾール剤には、必ずしも水の配合が必要でなく、全く新たな条件で噴出物を凝固させることに特徴がある。
【0008】
【発明の実施の形態】
本発明でシャーベット状とは、噴出した際に液化ガスが気化する冷却力により、塗布部位でエアゾール剤の内容物の一部が凝固した状態をいい、具体的には塗布部位で液体と微粒結晶の凝固物が混在する状態をいう。本発明では、噴出した際に低級アルコールが液体、直鎖モノカルボン酸が微粒結晶の凝固物として混在することにより持続した冷却効果を生じるものと推測される。
【0009】
本発明において炭素原子数1〜3の低級アルコールとは直鎖状または分岐鎖状のアルコールであり、具体的にはメタノール、エタノール、変性エタノール、プロパノール、イソプロパノールなどがあげられるが、特に好ましいものとしてエタノールおよびイソプロパノールをあげることができる。低級アルコールの配合量は原液の6〜99重量%が好ましく、さらに好ましくは10〜95重量%であり、最も好ましくは30〜90重量%である。低級アルコールの配合量が原液の6重量%未満であると原液と噴射剤が均一に混和しにくくなり、99重量%を越えると冷却効果の持続性が低下するからである。
【0010】
本発明の炭素原子数10〜22の直鎖モノカルボン酸は、飽和、不飽和のいずれでも使用できる。本発明の好ましい直鎖モノカルボン酸として、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸およびベヘニン酸をあげることができ、最も好ましいものとしてステアリン酸をあげることができる。
【0011】
直鎖モノカルボン酸の配合量は原液の1〜28重量%が好ましく、さらに好ましくは1.5〜20重量%であり、最も好ましくは2〜15重量%である。直鎖モノカルボン酸の配合量が原液の1重量%未満であると噴出物が凝固しにくくなるため、持続的な冷感が弱くなり、28重量%を越えると直鎖モノカルボン酸が溶解しにくくなるため、製造が煩雑になるからである。
【0012】
本発明では、直鎖モノカルボン酸は低級アルコールおよび液化ガスを混合したときに、完全に均一系になるものでなければ効果が得られない。そのため、直鎖モノカルボン酸の溶解性が不十分なときは他の溶剤、溶解補助剤、界面活性剤などを配合することもできる。
【0013】
液化ガスは通常エアゾール剤に噴射剤として使用されるものであればよいが、好ましいものとしてジメチルエーテル、n−ブタン、i−ブタン、プロパン、液化石油ガスなどの単独または混合物をあげることができ、特に好ましいものとしてジメチルエーテル、n−ブタンおよびi−ブタンをあげることができる。
【0014】
液化ガスの配合量は原液1重量部に対して0.5〜20重量部が好ましく、さらに好ましくは1〜9重量部である。原液1重量部に対する液化ガスの配合量が0.5重量部未満であるとエアゾールの冷感が低くなるため、痛み、かゆみを静める効果が弱くなり、液化ガスの配合量が20重量部を越えるとエアゾールの噴射性状が霧状になってしまい、持続した冷却効果が得にくくなるからである。
【0015】
本発明のエアゾール剤は、低級アルコールおよび直鎖モノカルボン酸を均一系になるように溶解し、必要であれば均一系を崩さない他の成分をさらに配合した原液をエアゾール容器に液化ガスと共に充填することにより製造することができる。エアゾール容器としては通常用いられる金属またはプラスチック製のものを用いることができる。冷却効果の持続の点からは、均一系を崩さない他の成分として、適量の水を配合するとさらに好ましい。原液中に水を配合する場合は原液全体の90重量%以下の量を配合することができるが、製剤設計の容易さの点から原液の20〜60重量%の配合が好ましい。
【0016】
本発明のエアゾール剤は患部の痛み、かゆみを静める効果を増進するため、消炎鎮痛剤、鎮痒剤、抗真菌剤、血管拡張剤、抗ヒスタミン剤、局所麻酔剤、抗菌剤、抗化膿性疾患剤、角質溶解剤、清涼剤などの薬効成分を配合することができる。特に本発明においては水に不安定な薬剤や、親油性の高い薬剤も配合することが可能である。薬効成分の配合量は成分により異なるが通常、製剤全体の0.001〜10重量%である。
【0017】
本発明のエアゾール剤は必要があれば抗酸化剤、経皮吸収促進剤、保湿剤、乳化助剤、ゲル化剤、粘着剤、香料、染料などの、エアゾール剤に通常使用される添加剤を配合することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an aerosol agent having a cooling effect enhanced by solidifying ejecta in a sherbet shape.
[0002]
[Prior art]
Conventionally, gels and aerosols have been generally used to relieve pain such as bruises, sprains, and muscle fatigue, and itching caused by athlete's foot and insect bites. However, gel agents have a weak immediate effect, and generally used aerosols have no lasting effect.
[0003]
In general, it is effective to cool the affected area in order to relieve pain and itching in the affected area. Therefore, as an aerosol agent having a continuous cooling effect, WO90 / 11068, JP-A-4-103526 and the like disclose an aerosol agent in which the ejected matter forms a sherbet-like foam gel. However, these aerosols have complicated manufacturing processes, and since it is essential to add water to the aerosol solution, water-unstable drugs and highly lipophilic drugs are included. It was difficult. Furthermore, these aerosol agents were not satisfactory in terms of the feeling of use.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to solve the disadvantages of the prior art and to provide an aerosol that has strong and sustained skin cooling when sprayed.
[0005]
[Means for Solving the Problems]
As a result of various studies to achieve the above-mentioned object, the present inventors have found that an aerosol agent containing a lower alcohol, a linear monocarboxylic acid and a liquefied gas has a sustained cooling effect due to solidification of the ejected matter in a sherbet shape. In addition, the present inventors have found that the usability is extremely excellent, and thus completed the present invention.
[0006]
That is, the present invention is an aerosol for skin cooling comprising a stock solution containing a lower alcohol having 1 to 3 carbon atoms and a linear monocarboxylic acid having 10 to 22 carbon atoms and a liquefied gas, wherein the ejected matter solidifies in a sherbet form at the application site. It is an agent. Conventionally, an aerosol for cooling the skin that exhibits a cooling effect by blending a linear monocarboxylic acid into the preparation has not been known.
[0007]
Conventionally known aerosol agents having a continuous skin cooling effect freeze the water that is blended with them to solidify the ejecta and maintain the cooling effect. However, the aerosol agent of the present invention does not necessarily contain water. There is no need for blending, and it is characterized by solidifying the ejecta under completely new conditions.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the sherbet shape means a state in which a part of the contents of the aerosol agent is solidified at the application site due to the cooling power that the liquefied gas evaporates when ejected. Specifically, the liquid and fine crystals are applied at the application site. It means a state where coagulum is mixed. In the present invention, it is presumed that, when ejected, the lower alcohol is liquid and the linear monocarboxylic acid is mixed as a solidified product of fine crystals, thereby producing a sustained cooling effect.
[0009]
In the present invention, the lower alcohol having 1 to 3 carbon atoms is a linear or branched alcohol, and specifically includes methanol, ethanol, denatured ethanol, propanol, isopropanol, and the like. Mention may be made of ethanol and isopropanol. The blending amount of the lower alcohol is preferably 6 to 99% by weight of the stock solution, more preferably 10 to 95% by weight, and most preferably 30 to 90% by weight. This is because when the blending amount of the lower alcohol is less than 6% by weight of the stock solution, the stock solution and the propellant are difficult to mix uniformly, and when it exceeds 99% by weight, the cooling effect persistence decreases.
[0010]
The straight-chain monocarboxylic acid having 10 to 22 carbon atoms of the present invention can be used either saturated or unsaturated. Preferred linear monocarboxylic acids of the present invention include lauric acid, myristic acid, palmitic acid, stearic acid and behenic acid, and most preferred is stearic acid.
[0011]
The blending amount of the linear monocarboxylic acid is preferably 1 to 28% by weight of the stock solution, more preferably 1.5 to 20% by weight, and most preferably 2 to 15% by weight. If the blending amount of the linear monocarboxylic acid is less than 1% by weight of the stock solution, the ejected product becomes difficult to coagulate, so that the continuous cooling sensation is weakened. If it exceeds 28% by weight, the linear monocarboxylic acid is dissolved. This is because the manufacturing becomes complicated.
[0012]
In the present invention, the effect is not obtained unless the linear monocarboxylic acid is completely homogeneous when a lower alcohol and a liquefied gas are mixed. Therefore, when the solubility of the linear monocarboxylic acid is insufficient, other solvents, solubilizing agents, surfactants, and the like can be blended.
[0013]
The liquefied gas may be any one that is usually used as a propellant in an aerosol, but preferred examples include dimethyl ether, n-butane, i-butane, propane, liquefied petroleum gas, etc., alone or as a mixture. Preferable examples include dimethyl ether, n-butane and i-butane.
[0014]
The blending amount of the liquefied gas is preferably 0.5 to 20 parts by weight, more preferably 1 to 9 parts by weight with respect to 1 part by weight of the stock solution. If the amount of liquefied gas added to 1 part by weight of the stock solution is less than 0.5 part by weight, the cooling sensation of the aerosol will be low, so the effect of calming pain and itch will be weakened, and the amount of liquefied gas will exceed 20 parts by weight. This is because the spraying property of the aerosol becomes mist and it is difficult to obtain a sustained cooling effect.
[0015]
The aerosol agent of the present invention dissolves a lower alcohol and a linear monocarboxylic acid so as to be a homogeneous system, and if necessary, fills an aerosol container with a liquefied gas together with other components that do not disrupt the homogeneous system. Can be manufactured. As the aerosol container, a commonly used metal or plastic one can be used. From the viewpoint of sustaining the cooling effect, it is more preferable to add an appropriate amount of water as another component that does not break the uniform system. When water is blended in the stock solution, an amount of 90% by weight or less of the whole stock solution can be blended, but 20 to 60% by weight of the stock solution is preferred from the viewpoint of ease of formulation design.
[0016]
The aerosol agent of the present invention enhances the effect of calming the pain and itch of the affected area. Medicinal components such as a solubilizer and a refreshing agent can be blended. In particular, in the present invention, a water-unstable drug or a highly lipophilic drug can be added. The compounding amount of the medicinal component is usually 0.001 to 10% by weight of the whole preparation although it varies depending on the component.
[0017]
If necessary, the aerosol of the present invention can be prepared by adding additives usually used for aerosols, such as antioxidants, transdermal absorption promoters, moisturizers, emulsifying aids, gelling agents, adhesives, fragrances, and dyes. Can be blended.
