Abstract
【解決手段】本発明は、光感作剤及び皮膚浸透エンハンサーを含有する組成物を提供する。本出願における組成物では、角質層を介した光感作剤の送達が改善されている。加えて、本発明の組成物では、安定性が改善され、及び、皮膚光感受性の影響が低下されている。
【選択図】なし
Description
いくつかの適当な光感作剤を本出願において使用してもよい。一般に、これらは400nm〜800nm、多くの場合600nm〜750nmの範囲内の光を吸収するであろう。
本発明の組成物は、皮膚浸透エンハンサーを含まなければならない。本明細書において使用されている用語「皮膚浸透エンハンサー(skin-penetration enhancer)」とは、皮膚の角質層(Stratum Corneum)を介した光感作剤の送達の助けになる物質又は物質の混合物を意味する。
本出願における組成物は、溶解補助剤を含むことが好ましい。このことは、光感作剤が疎水性である場合に特に適当である。溶解補助剤の中にも浸透エンハンサーであるものがある。本出願における組成物は、光感作剤用の溶解補助剤でもある浸透エンハンサーを含むことが好ましい。
本出願における組成物は、好ましくは粘度改良剤を含む。好ましくは、粘度改良剤は、ポリエチレングリコール、アクリル酸ベースポリマー(カーボポルポリマー又はカーボマー)、アリルスクロース又はアリルペンタエリトリトールと架橋したアクリル酸ポリマー(カーボポルホモポリマー)、長鎖(C10−C30)アルキルアクリレートにより修飾され及びアリルペンタエリトリトールと架橋したアクリル酸ポリマー(カーボポルコポリマー)、プルロニクス(pluronics)としても知られるポロキサマー(poloxamers)(ブロックポリマー;例えば、Poloxamer 124、188、237、338、407)、ロウ類(パラフィン、グリセリルモノステアレート、ジエチレングリコールモノステアレート、プロピレングリコールモノステアレート、エチレングリコールモノステアレート、グリコールステアレート)、硬質脂肪(hard fats)(例えば、飽和C8-C18脂肪酸グリセリド)、キサンタンガム、ポリビニルアルコール、固体アルコール類、並びにこれらの混合物から選択される。より好ましくは、粘度改良剤は、高分子量ポリエチレングリコールから選択され、特にPEG−3350が好ましい。
本出願における組成物は、種々の任意成分を含んでもよい。いくつかの適当な成分を使用してもよいが、一般に、これらの任意成分が組成物をより化粧用に良好なものとし又は補助的な用法で利益をもたらすであろう。好ましい任意成分のいくつかの例には、乳化剤、希釈剤、緩和剤、界面活性剤、油類、ロウ類、脂肪族アルコール類、分散剤、皮膚用薬剤(skin-benefit agent)、pH調整剤、染料/色素、鎮痛剤、香料、防腐剤、及びこれらの混合物が含まれるが、それらに限定されない。
本発明はまた前記記載した組成物を使用する方法にも関する。当該方法は下記を含む:
(i)光感作剤と、皮膚浸透エンハンサーを含む担体とを含有する組成物を皮膚に塗布
すること、
(ii)前記光感作剤の少なくとも一部について、角質層を介して浸透させるための時間
を見込むこと、
(iii)前記組成物が塗布された皮膚を洗浄すること、並びに
(iv)前記光感作剤を活性化させるために適当な波長で活性化エネルギーを照射するこ
と。
本発明の組成物を、いくつかの適当なプロセスによって製造することができる。好ましくは、光感作剤は凍結乾燥される。本発明の組成物の製造のための好ましいプロセスは、下記工程を含む:
a)凍結乾燥した光感作剤の調製、
b)皮膚浸透エンハンサー及び、任意に溶解補助剤を含むベース組成物の製造、並びに
c)撹拌しながらのベース組成物への光感作剤の添加。
本発明の組成物を、育毛を促進するために使用してもよい。本発明の方法は、本発明の組成物を適当な標的に対して適用(塗布)すること及び光感作剤を活性化することを含む。一般に、約0.1g〜約50g、好ましくは約1g〜約10g、の組成物が標的に対して適用される。活性化エネルギーを適当なエネルギー源からのものにすることができる。
a)凍結乾燥した光感作剤の調製
QLT0074を氷酢酸に溶解した。その後、溶液をドライアイス/イソプロパノール浴中で凍結させ、酢酸を凍結乾燥により除去した。結果として生じた物質は、容易に局所用溶液に溶解する微細な軽い粉末であった。
b)ベースの製造
PEG200を撹拌しながら80〜90℃まで温めた。PEG3.35Kを撹拌しながら加え、次いでオレイルアルコールを加えた。そのときそこでtranscutol(登録商標)を与えた。撹拌は、溶液が透き通るまで続けられた。
c)光感作剤の添加
ベース組成物を約50℃まで冷却し、光感作剤を撹拌しながら加えた。撹拌は均一なペーストが得られるまで冷却しながら続けられた。結果として生じた調製物について、位相差顕微鏡により溶解していない光感作剤の結晶の不在を確認した。
