表2に示す組成を持つ香料組成物965質量部に、実施例1で得られたα-メタクリロイルオキシイソ酪酸イソプロピル35質量部を加えた香料組成物を調合した。
調香師による香気評価により、表2に記載した組成を持つ香料組成物に実施例1のα-メタクリロイルオキシイソ酪酸イソプロピルを添加することにより、力強いグリーン感やフルーティ感を付与することができた。その結果、クリーナーなどのハウスホールド等に利用できるフルーティハーバルタイプの香料組成物を得ることができた。

調香師による香気評価により、表3に記載した組成を持つ香料組成物に実施例7のα-2-メチル-2-ブテノイルオキシイソ酪酸イソプロピルを添加することにより、香りの拡散性が上がり、トップノートに広がりのある調合香料となった。その結果、ナチュラルなイメージのベース香料として利用できる天然精油的なマグノリアタイプの香料組成物を得ることができた。
このことから、本発明のα位にアルケノイルオキシ基を有するイソ酪酸エステル化合物は、香料組成物の有効成分として有用であり、得られた香料組成物は、各種製品に配合することにより、所望の賦香性を発揮することができる。
また、本発明のα位にアルケノイルオキシ基を有するイソ酪酸エステル化合物は、フローラルな香気とその他の香気の複合的な香りを有することから香料として有用であることがわかる。本発明のα位にアルケノイルオキシ基を有するイソ酪酸エステル化合物は、フローラルの香気を持つが、それに加えて不飽和炭化水素基及びアルキル基の違いによってグリーン調、ローズ調、ハーバル調、ウッディ調、バルサミック調、フルーティ調などの香気も同時に示すことがわかる。
このことから、本発明のα位にアルケノイルオキシ基を有するイソ酪酸エステル化合物は、香料として有用であり、香料として好適に使用することができる。
