Description
悪臭制御組成物は揮発性アルデヒドの混合物を含み、純粋な悪臭中和を供給するように設計されており、臭気を単に隠す又は被覆することにより機能するものではない。純粋な悪臭中和は、感覚及び分析により測定可能(例えば、ガスクロマトグラフ)な悪臭の低減を供給する。したがって、悪臭制御組成物が純粋な悪臭中和を供給する場合には、この組成物は、気相及び/又は液相中の悪臭を低減する。
悪臭制御組成物は、化学反応を介して気相及び/又は液相中の悪臭を中和する揮発性アルデヒドの混合物を含む。このような揮発性アルデヒドは、反応性アルデヒド(RA)とも呼ばれる。揮発性アルデヒドは、シッフ塩基形成経路に従ってアミン系臭気と反応し得る。揮発性アルデヒドは、イオウ系臭気とも反応し、気相及び/又は液相中にチオールアセタール、へミチオールアセタール及びチオールエステルを形成し得る。実質上、製品の所望の芳香特性に負の影響を全く有さないことが、これらの気相及び/又は液相揮発性アルデヒドにとって望ましいものであり得る。部分的に揮発性であるアルデヒドは、本明細書で使用される揮発性アルデヒドと考えられ得る。
本発明の悪臭制御組成物は、イオウ系悪臭を中和するために、有効量の酸触媒を含んでもよい。特定の弱酸は、液相及び気相中のチオールとのアルデヒド反応性に影響を有することが判明している。チオールとアルデヒドとの間の反応は、ヘミアセタール及びアセタール形成経路の機構に従う触媒反応であることが判明している。本悪臭制御組成物が酸触媒を含有し、イオウ系悪臭と接触すると、揮発性アルデヒドはチオールと反応する。この反応は、チオールアセタール化合物を形成し、したがって、イオウ系臭気を中和し得る。酸触媒がないと、へミチオールのみが形成される。
悪臭制御組成物は、所望により、マスキング剤、臭気ブロック剤及び/又は希釈剤を含んでもよい。例えば、悪臭制御組成物は、悪臭を中和するための揮発性アルデヒドと芳香剤イオノンと希釈剤との混合物を含み得る。あるいは、悪臭制御組成物は、100%揮発性アルデヒドから構成されてもよい。
本発明はまた、悪臭を中和するための揮発性アルデヒドを選択するための方法を含む。この方法は、40秒の時点で少なくとも20%のアミン系臭気を除去する、及び/又は、30分の時点で少なくとも20%のチオール系臭気を除去する、アルデヒドを選択することを含み得る。
本発明の悪臭制御組成物は、気相及び/又は液相中の悪臭を中和する広範囲の用途に使用され得る。一部の実施形態では、悪臭制御組成物は、エネルギー作動式気相システム中での使用のために配合され得る。本明細書で使用するとき、「エネルギー作動式」は、電池、電気壁コンセントなどの電気エネルギー源を用いることにより作動して標的の活性物質を放出するシステムを指す。このようなシステムでは、揮発性アルデヒドのVPは、25℃にて測定したときに、約0.001トール(0.133Pa)〜約20トール(2666Pa)、又は約0.01トール(1.33Pa)〜約10トール(1333Pa)であり得る。エネルギー作動式気相システムの一例は、液体電気プラグインタイプ空気フレッシュニング装置である。
1mLのブチルアミン(アミン系悪臭)及びブタンチオール(イオウ系悪臭)を1.2リットルのガスサンプリングバッグの中にピペットで加えることにより、悪臭標準物質を調製する。次に、このバッグに窒素を容量まで充填し、少なくとも12時間にわたって静置して、平衡状態にする。
イオウ系悪臭における酸触媒の効果を試験するために、上記分析試験を、酸触媒を含有する試料を用いて繰り返す。特に、以下の対照及び酸触媒試料の各々の1μLアリコートを、二通り用意した個々の10mLシラン処理済みヘッドスペースバイアル瓶にピペットを用いて加える:対照としてのチオフェンカルボキシアルデヒド;チオフェンカルボキシアルデヒドとDPM中0.04%、DPM中0.10%、DPM中0.43%、DPM中1.02%及びDPM中2.04%での以下の酸触媒各々との50/50混合物:フェノール、メシチレン酸、カプリル酸、コハク酸、ピバル酸、チグリン酸及び安息香酸。
表8及び9の概要の通りに揮発性アルデヒド(又はRA)と酸触媒とを含有する試料配合物を用いて、上記分析試験を繰り返す。
Presto(商標)スキレットを換気フードの中に置き、121℃(250°F)にする。80グラムのCrisco(登録商標)油をスキレットの中に置き、スキレットの蓋で覆う。平衡化のために10分そのままにしておく。スキレットの蓋を取り外し、温度計で油の温度をチェックする。50グラムの刻んだ商業的に調製された水中ニンニクをスキレットの中に置く。スキレットを蓋で覆う。2.5分にわたって又はニンニクが半透明になるまで調理する。一部は茶色に変色し始めるが、焦げてはいない。ニンニクをスキレットから取り出す。4枚のペトリ皿の各々に5グラムのニンニクを置く。各ペトリ皿にカバーを置く。
新鮮なアカウオ(ocean perch)の切り身を皮から剥がし、Magic Bullet(商標)フードチョッパーに入れる。魚肉を35〜40秒にわたって刻む。25グラムの刻んだ魚を計量し、60×15mmペトリ皿の中にぴったり収まるようにパテにする。更に3回繰り返すことで、その結果、4枚のペトリ皿の各々に1つの魚パテが存在するようになる。40gのCrisco(登録商標)油をPresto(商標)スキレットに加える。スキレットに蓋を置き、177℃(350°F)にする。平衡化のために10分そのままにしておく。蓋を取り外す。各パテの真ん中にスリットを刻み、1つのパテをスキレットの中に置き、揚げ始める。蓋を再び置く。2.5分後、魚パテをひっくり返し、更に2.5分揚げる。スキレットから魚パテを取り出し、10秒にわたってペーパータオル上で簡単に拭く。残りの3つのパテを同様に揚げる。各魚パテを60×15mmのペトリ皿の中に置き、蓋でカバーする。
表14に概要を示した2つの配合物を用いて、次に表15に概要を示した2つの配合物を用いて、ただし、表15の配合物はProcter and Gamble Companyにより流通している2つのFebreze(登録商標)Set & Refresh受動的空気フレッシュナー(Febreze Noticeable装置と対比)内に別々に充填されることを除き、アミン系及びイオウ系悪臭に対する上記感覚試験プロトコルを繰り返す。&結果は表14及び15に示されている。
