REACH 制限物質(その26):Entry43 

REACH 制限物質(その26)は、Entry43のAzocolourants and Azodyesです。日本語では直訳すればアゾ着色剤およびアゾ染料ですが、よくアゾ染料・顔料とかアゾ色素のような表現も使われていますね。
しかもこれは、管理人の嫌いな物質群じゃないか!展開してみると管理人が数え間違えしていなければ、172物質もあります。

もうこの時点でいやです。

最初にアップした際、Azocolourants and AzodyesがEntry44で上げてしまいました。申し訳ありません。Entry44は欠番です。

Entry43 Azocolourants and Azodyesの基本情報

まずは、Entry43 Azocolourants and Azodyesの基本情報を見ていきましょう。といっても172物質もあっては何を書けばいいかよくわかりません。

なので、適当に書いちゃいます。

アゾ色素は、アゾ化合物である色素を指すのが普通です。しかしながら、展開した172物質の中にはアゾ化合物ではないものも含まれています。これは、これらの物質群の制限条件に依存しています。

アゾ化合物は、アゾ基を含む化合物の総称ですが、アゾ基は-N=N-で示される官能基です。

以下に展開されたときに出てくる化合物を示しますが、管理人がただページ数と文字数を稼ぎたいだけです、しかも、コピペだし(^^;。
番号は、オリジナルのECHAにあるリストには記載されていません。数を数えるため便宜上振っただけです。

Entry43 Azocolourants and Azodyesの危険性は何か

次にEntry43 Azocolourants and Azodyesの危険性について見ていきましょう。

これも、制限条件を見ると分かるのですが、アゾ色素が悪いわけではなく、その分解物として生じる芳香族アミンが発がん性であるための危険性となっています。

どこに使われているか

アゾ色素は染料・顔料としての用途ですから、色を付ける必要があるところにはほとんど使われることになります。
身近なものとしては、衣類とか鞄、帽子なども含めたファッション関係の品などがあります。印刷用もそうでしょうし、プラスチックの着色などいろいろなところに使用されます。

以下の制限条件を見ると分かるのですが、アゾ色素全部が制限されているわけではなく、特定のものが制限されます。

制限条件

Entry43 Azocolourants and Azodyesの制限条件は以下のようなものです。

  1. 一つまたは複数のアゾ基の還元的切断により、附属書8に記載されている一つまたは複数の芳香族アミンを、附属書10に記載されている試験方法により、物品またはその染色部分に検出可能な濃度、すなわち30mg/kg(0.003重量%)を超えて放出する可能性のあるアゾ染料は、以下のような人間の皮膚または口腔と直接かつ長時間接触する可能性のある繊維および皮革製品に使用してはならない。
    ー衣類、寝具、タオル、ヘアピース、ウィッグ、帽子、おむつ、その他の衛生用品、寝袋
    ー履物、手袋、腕時計のストラップ、ハンドバッグ、財布、ブリーフケース、椅子カバー、首から下げた財布など
    ー織物または皮革製の玩具、および織物または皮革製の衣服を含む玩具
    ー最終消費者が使用することを目的とした糸、布地
  2. さらに、第1項で言及された繊維および皮革製品は、同項で定められた要求事項に適合しない限り、市場に出してはならない。
  3. 附属書9「アゾ染料リスト」に含まれるアゾ染料は、物質または混合物が繊維・皮革製品の着色を目的としている場合、0.1重量%を超える濃度の物質または混合物として上市、または使用してはならない。

ということなので、本来なら附属書8から10までも解説しなければならないのですが、そこは自分でお願いします。附属書8には芳香族アミンが22物質載っています。附属書9にはアゾ染料1種類(少なくともEC番号では一つで表されています)が、附属書10には測定方法が皮と織物に関して4種類記載されています。
