Description

【0001】
【発明の属する技術分野】
本発明は皮膚外用剤に関する技術分野に属し、詳しくはニキビ治療効果に優れた皮膚外用剤に関する技術分野に属する。
【0002】
【従来の技術】
ニキビは主として思春期に発現する皮膚疾患で、その正式な病名を尋常性座瘡といい、臨床的には“毛嚢脂腺系を中心に毛孔に起こる慢性の炎症性変化”と定義されている。その発症病理はいまだ不明な点が多いが、一般には皮脂分泌過剰,毛嚢角化,毛嚢内細菌が重要な役割を果たしつつ、種々の要因が複雑に絡み合っている皮膚疾患であると考えられている。
従って、ニキビ治療用の外用剤としては、上記の各要因に対応して、皮脂分泌抑制成分、角質溶解成分及び/又は抗菌物質を配合したクリームや軟膏が一般に多く用いられている。
【0003】
【発明が解決しようとする課題】
しかし、上記の各種成分を配合した既存のニキビ治療薬においても種々の欠点が報告されている。例えば、皮脂分泌抑制成分である女性ホルモンは、表皮の成長を抑制し皮脂の分泌を減少させるが、この種のホルモンがひきおこす副作用は、特に思春期の男女には好ましいものではない。
また、皮脂抑制作用を有する塩酸ピリドキシンやシャクヤクエキス,ゴボウエキスといった生薬類は単独でクリームや軟膏等に配合しても十分な皮脂抑制効果はみられず、ニキビ治療の効果は必ずしも十分なものではなかった。
【0004】
さらに、角質溶解成分の代表例である硫黄や二硫化セレン等の硫黄化合物は、上記の女性ホルモンのような副作用は認められないが、連用することにより皮膚刺激や皮膚のかさつき等を起こす場合が多い。
そこで、本発明が解決すべき課題は、ホルモン様の副作用を有さず、皮膚に対して温和で、かつニキビ治療効果に優れた薬剤を提供することにある。
【0005】
【課題を解決するための手段】
そこで、本発明者は上記課題を解決すべく鋭意検討を重ねた結果、特定量のベタイン類とピリドキシン類とトラネキサム酸類を有効成分として配合した皮膚外用剤は、皮脂抑制効果に優れつつ皮膚に対して温和で、さらに異常角化を抑え、ニキビ治療の目的を良好に達成することを見出した。
【0006】
すなわち、本発明は、下記の成分(1)〜(3)を有効成分として配合されている、ニキビ治療用皮膚外用剤を提供する発明である。
(1)ベタイン類を、剤全体に対して0.01〜10.0重量%
(2)ピリドキシン類を、剤全体に対して0.01〜5.0重量%
(3)トラネキサム酸類を、剤全体に対して0.01〜5.0重量%
【0007】
【発明の実施の形態】
以下、本発明の実施の形態について説明する。
A.本発明皮膚外用剤は、ベタイン類及びピリドキシン類を有効成分として配合した皮膚外用剤である。本発明皮膚外用剤に有効成分として配合可能なベタイン類は、皮膚外用剤の配合成分として配合することが安全性等の面で可能である限り特に限定されず、この条件を満たす「1分子中に陽イオンとして第4級アンモニウムと、カルボン酸等の陰イオン性を有する分子内塩」であれば配合することができる。
【0008】
具体的には、例えばリジンベタイン,オルニチンベタイン,ホマリン,トリゴネリン,アラニンベタイン,タウロベタイン,カルニチン,スタキドリン,グルタミン酸ベタイン,フェニルアラニルベタイン,γ−ブチロベタイン,グリシンベタイン等の低分子ベタインを本発明皮膚外用剤中に配合することができる。
【0009】
これらのベタイン類の中でも、アラニンベタイン,グリシンベタイン,リジンベタインは、これらを配合した本発明皮膚外用剤は、安定性及び使用性に特に優れるという点において特に好ましいベタイン類として本発明皮膚外用剤中に配合することができる。
【0010】
また、これらのベタイン類は、単独で本発明皮膚外用剤中に配合することも可能であるが、必要に応じて2種以上を組み合わせて本発明皮膚外用剤中に配合することも可能である。
【0011】
本発明皮膚外用剤における上記のベタイン類の配合量は、皮膚外用剤全体に対して0.01重量%以上,30.0重量%以下が好ましく、同0.1重量%以上,10.0重量%以下が特に好ましい。
【0012】
ベタイン類の配合量が皮膚外用剤全体に対して0.01重量%未満では、所望する角栓除去効果が発揮され難い故に好ましくなく、同30.0重量%を超えるとベタイン類の溶解性が劣る傾向が顕著になり製剤上好ましくなく、配合量に見合ったニキビ抑制効果の増大が認められない傾向にもなり好ましくない。
【0013】
なお、本発明皮膚外用剤中に配合され得るベタイン類は、アミノ酸のアルキル化やハロゲン置換カルボン酸と第3級アミンとの反応等の通常公知の手段により製造することが可能であり、そのベタイン類を含む生物から抽出して製造することも可能である。また、上記のベタイン類の市販品を用いることも可能である。
【0016】
なお、本発明皮膚外用剤に配合するピリドキシン類は、ビタミンB 6 として知られているピリドキシンであり、ピリドキシン誘導体及びこれらの塩を含む。具体的には、例えば、塩酸ピリドキシン,ジカプリル酸ピリドキシン,ジパルミチン酸ピリドキシン,グリチルリチン酸ピリドキシン,ジラウリン酸ピリドキシン,トリパルミチン酸ピリドキシン,リン酸ピリドキサール等を挙げることができる。これらを配合した本発明皮膚外用剤は、安定性及び使用性に特に優れる。
【0017】
また、これらのピリドキシン類は、単独で本発明皮膚外用剤中に配合することも可能であるが、必要に応じて2種以上を組み合わせて本発明皮膚外用剤中に配合することも可能である。
【0018】
本発明皮膚外用剤における上記のピリドキシン類の配合量は、皮膚外用剤全体に対して0.0001重量%以上,10.0重量%以下が好ましく、同0.01重量%以上,5.0重量%以下が特に好ましい。
【0019】
このピリドキシン類の場合、配合量が皮膚外用剤全体に対して0.0001重量%未満では、所望する皮脂抑制効果が発揮され難い故好ましくなく、同10.0重量%を超えると配合量に見合った皮脂抑制効果の増大が認められない傾向になり好ましくない。
【0020】
このように、ベタイン類とピリドキシン類とを有効成分として組み合わせて配合することにより、配合したピリドキシン類の皮脂抑制効果自体を損なうことなく、皮膚に対して温和で、しかも角化異常を抑制することができる皮膚外用剤が提供される。
【0021】
なお、本発明皮膚外用剤は、女性ホルモン等のホルモン類の配合自体を妨げるものではないが、ベタイン類のとの組み合わせ配合によりホルモン様の副作用の惹起自体を抑制し得るものではない。よって、本発明皮膚外用剤中にホルモン類を配合する場合には、その副作用について従来のにきび抑制剤と同様の配慮をする必要がある。
【0022】
B.本発明皮膚外用剤は、上記の有効成分に加えてトラネキサム酸類を配合することにより、一層にきび抑制効果を向上させることができる。トラネキサム酸類とは、トラネキサム酸及びその塩類や、トラネキサム酸メチルアミド及びその塩酸塩、トラネキサム酸ヘキシルアミド等のトラネキサム酸誘導体を意味する。また、トラネキサム酸塩とは、薬学上用いることが可能なトラネキサム酸塩のことを意味する。
【0025】
また、これらのトラネキサム酸類は、単独で本発明皮膚外用剤中に配合することも可能であるが、必要に応じて2種以上を組み合わせて本発明皮膚外用剤中に配合することも可能である。
【0026】
本発明皮膚外用剤における上記のトラネキサム酸類の配合量は、皮膚外用剤全体に対して0.001重量%異常,10.0重量%以下が好ましく、同0.01重量%以上,5.0重量%以下が特に好ましい。
【0027】
このトラネキサム酸の場合、配合量が皮膚外用剤全体に対して0.001重量%未満では、トラネキサム酸を配合したことによるにきび抑制効果の相乗的向上を図ることが困難であり好ましくなく、同10.0重量%を超えても配合量の増加に見合ったにきび抑制効果の相乗的向上がもはや見られず好ましくない。
【0028】
このように、ベタイン類及びピリドキシン類に加えて、トラネキサム酸類を配合することにより、本発明皮膚外用剤において所望するにきび抑制効果が相乗的に向上する。
【0029】
また、上記の必須又は準必須の有効成分に加えて、他の薬効成分を、本発明の所期の効果を損なわない範囲で、またその薬効成分を皮膚外用剤中に配合することで発揮される効果が予測される範囲で本発明皮膚外用剤中に配合することができる。
【0030】
例えば、ビタミンA酸及びその誘導体、サリチル酸、亜鉛及びその化合物、乳酸等の薬効成分を本発明皮膚外用剤中に配合することができる。また、角質溶解剤やヒアルロン酸等の保湿剤を本発明皮膚外用剤中に配合することができる。
【0031】
なお、本発明皮膚外用剤中に配合可能な「他の薬剤等」が、ここに例示したものに限定されるものではないこと、及びこれらの「他の薬剤等」を1種のみならず、必要に応じて2種以上を組み合わせて本発明皮膚外用剤中に配合可能であることは勿論である。
【0032】
また、本発明皮膚外用剤が採る具体的な剤型及び形態に応じて、通常公知の基剤成分等を、本発明皮膚外用剤の基剤成分等として用いることができる。
すなわち、各種油分,界面活性剤,水,エタノール,増粘剤,香料,色素等を本発明の所期の効果を損なわない範囲で本発明皮膚外用剤の基剤成分等として用いることができる。
【0033】
なお、本発明皮膚外用剤が採り得る剤型は特に限定されず、クリーム,ローション,乳液,パック,白粉,軟膏等外皮に適用できるものであればいずれも選択することができる。
【0034】

TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field related to skin external preparations, and more specifically, to the technical field related to skin external preparations that are excellent in treating acne.
[0002]
[Prior art]
Acne is a skin disease that mainly manifests during puberty, and its formal name is acne vulgaris, clinically defined as "chronic inflammatory changes in the pores, especially in the pilosebaceous system". I have. Although the pathogenesis is still largely unknown, it is generally considered to be a skin disease in which various factors are intricately intertwined while hypersecretion of sebum, keratinization of hair follicles, and bacteria in hair follicles play important roles. ing.
Therefore, as an external preparation for acne treatment, creams and ointments containing a sebum secretion inhibitor, a keratolytic component and / or an antibacterial substance are generally widely used depending on the above factors.
[0003]
[Problems to be solved by the invention]
However, various drawbacks have also been reported for existing acne treatment drugs containing the various components described above. For example, female hormones, which are sebum secretion inhibitory components, inhibit epidermal growth and reduce sebum secretion, but the side effects caused by these hormones are not particularly favorable for adolescent men and women.
Crude drugs such as pyridoxine hydrochloride, peonies extract, and burdock extract, which have sebum-suppressing effects, do not show a sufficient sebum-suppressing effect even when used alone in creams or ointments, and the effect of acne treatment is not necessarily sufficient. Did not.
[0004]
Furthermore, sulfur compounds such as sulfur and selenium disulfide, which are typical examples of the keratolytic component, do not have side effects like the above-mentioned female hormones, but may cause skin irritation and skin bulking by continuous use. Many.
The problem to be solved by the present invention is to provide a drug which does not have hormone-like side effects, is mild on the skin, and has an excellent acne treatment effect.
[0005]
[Means for Solving the Problems]
Therefore, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, a skin external preparation containing a specific amount of betaines, pyridoxines and tranexamic acids as active ingredients is excellent in sebum-suppressing effect and is effective for skin. It was found that it was mild and mild, further suppressed abnormal keratinization, and successfully achieved the purpose of acne treatment.
[0006]
That is, the present invention is an invention which provides a skin external preparation for acne treatment, which contains the following components (1) to (3) as active ingredients.
(1) Betaines are contained in an amount of 0.01 to 10.0% by weight based on the whole preparation.
(2) A pyridoxine compound is used in an amount of 0.01 to 5.0% by weight based on the whole preparation.
(3) Tranexamic acids are added in an amount of 0.01 to 5.0% by weight based on the total amount of the agent.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
A. The skin external preparation of the present invention is a skin external preparation containing betaines and pyridoxines as active ingredients. The betaines that can be blended as an active ingredient in the skin external preparation of the present invention are not particularly limited as long as they can be blended as components of the skin external preparation in terms of safety and the like. And a quaternary ammonium as a cation and an anionic salt having an anionic property such as a carboxylic acid.
[0008]
Specifically, for example, low-molecular-weight betaines such as lysine betaine, ornithine betaine, homalin, trigonelin, alanine betaine, taurobetaine, carnitine, staquidrine, betaine glutamate, phenylalanyl betaine, γ-butyrobetaine, and glycine betaine are used for external application to the skin of the present invention. It can be blended in the composition.
[0009]
Among these betaines, alanine betaine, glycine betaine, and lysine betaine are the skin external preparations of the present invention containing these, which are particularly preferred in that they are particularly excellent in stability and usability. Can be blended.
[0010]
These betaines can be used alone in the external preparation for skin of the present invention, but if necessary, two or more of them can be mixed in the external preparation for skin of the present invention. .
[0011]
The content of the above betaines in the skin external preparation of the present invention is preferably 0.01% by weight or more and 30.0% by weight or less, and more preferably 0.1% by weight or more and 10.0% by weight based on the whole skin external preparation. % Or less is particularly preferred.
[0012]
If the amount of betaines is less than 0.01% by weight based on the total amount of the external preparation for skin, the desired keratotic plug-removing effect is not easily exerted, which is not preferable. If the amount exceeds 30.0% by weight, the solubility of betaines becomes poor. The inferior tendency becomes remarkable, which is not preferable in terms of formulation, and the increase in acne suppression effect commensurate with the compounding amount tends to not be observed, which is not preferable.
[0013]
The betaines that can be incorporated in the skin preparation for external use of the present invention can be produced by commonly known means such as alkylation of amino acids and reaction of a halogen-substituted carboxylic acid with a tertiary amine. It is also possible to produce by extracting from organisms including species. It is also possible to use the commercially available betaines described above.
[0016]
The pyridoxine compounded in the external preparation for skin of the present invention is pyridoxine known as vitamin B 6 and includes pyridoxine derivatives and salts thereof. Specific examples include pyridoxine hydrochloride, pyridoxine dicaprylate, pyridoxine dipalmitate, pyridoxine glycyrrhizinate, pyridoxine dilaurate, pyridoxine tripalmitate, pyridoxal phosphate, and the like. The skin preparation for external use of the present invention in which these are blended is particularly excellent in stability and usability.
[0017]
These pyridoxines can be used alone in the external preparation for skin of the present invention, but if necessary, two or more of them can be mixed in the external preparation for skin of the present invention. .
[0018]
The amount of the pyridoxine compound in the skin external preparation of the present invention is preferably 0.0001% by weight or more and 10.0% by weight or less, preferably 0.01% by weight or more and 5.0% by weight based on the whole skin external preparation. % Or less is particularly preferred.
[0019]
In the case of these pyridoxines, if the amount is less than 0.0001% by weight based on the total amount of the external preparation for skin, the desired sebum-suppressing effect is difficult to be exerted, which is not preferable. This is not preferable because an increase in sebum suppression effect tends to be not observed.
[0020]
In this way, by combining and combining betaines and pyridoxines as active ingredients , it is mild to the skin and suppresses abnormal keratinization without impairing the sebum suppression effect itself of the combined pyridoxines. An external preparation for skin is provided.
[0021]
The external preparation for skin of the present invention does not hinder the addition of hormones such as female hormones, but cannot inhibit the occurrence of hormone-like side effects by combination with betaines. Therefore, when hormones are incorporated into the external preparation for skin of the present invention, the same side effects as those of conventional acne inhibitors must be considered.
[0022]
B. The skin external preparation of the present invention can further improve the acne suppressing effect by blending tranexamic acids in addition to the above-mentioned active ingredients. Tranexamic acids mean tranexamic acid and its salts, tranexamic acid methylamide and its hydrochloride, and tranexamic acid derivatives such as tranexamic acid hexylamide. In addition, tranexamate means tranexamate that can be used pharmaceutically.
[0025]
In addition, these tranexamic acids can be used alone in the external preparation for skin of the present invention, but if necessary, two or more of them can be mixed in the external preparation for skin of the present invention. .
[0026]
The amount of the above-mentioned tranexamic acids in the skin external preparation of the present invention is preferably 0.001% by weight, 10.0% by weight or less, preferably 0.01% by weight or more and 5.0% by weight, based on the whole skin external preparation. % Or less is particularly preferred.
[0027]
In the case of this tranexamic acid, if the amount is less than 0.001% by weight based on the total amount of the external preparation for skin, it is difficult to synergistically improve the acne-suppressing effect by adding tranexamic acid. Even if the amount exceeds 0.0% by weight, a synergistic improvement in acne suppression effect commensurate with the increase in the blending amount can no longer be seen, which is not preferable.
[0028]
Thus , by adding tranexamic acids in addition to betaines and pyridoxines , the desired acne-suppressing effect of the external preparation for skin of the present invention is synergistically improved.
[0029]
Further, in addition to the above-mentioned essential or semi-essential active ingredients, other medicinal ingredients are exhibited in a range that does not impair the intended effects of the present invention, and are also exhibited by incorporating the medicinal ingredients into a skin external preparation. Can be incorporated into the external preparation for skin of the present invention within a range in which the effect is expected.
[0030]
For example, medicinal ingredients such as vitamin A acid and its derivatives, salicylic acid, zinc and its compounds, and lactic acid can be incorporated into the skin external preparation of the present invention. Further, a humectant such as a keratolytic agent or hyaluronic acid can be incorporated in the external preparation for skin of the present invention.
[0031]
In addition, "other drugs etc." which can be mix | blended in the skin external preparation of this invention are not limited to what was illustrated here, and these "other drugs etc." are not only one kind, If necessary, two or more kinds may be combined in the external preparation for skin of the present invention.
[0032]
In addition, depending on the specific dosage form and form of the external preparation for skin of the present invention, generally known base components and the like can be used as the base components and the like of the external preparation for skin of the present invention.
That is, various oils, surfactants, water, ethanol, thickeners, fragrances, dyes, and the like can be used as the base components and the like of the external preparation for skin of the present invention as long as the desired effects of the present invention are not impaired.
[0033]
The dosage form that the skin external preparation of the present invention can take is not particularly limited, and any cream, lotion, milky lotion, pack, white powder, ointment and the like that can be applied to the skin can be selected.
[0034]
