PROBLEM TO BE SOLVED: To provide a CNG channel inhibitor having a sufficient effect of reducing olfactory sensitivity and less irritation to eyes or the like, a composition for reducing the olfactory sensitivity containing the inhibitor and a deodorization method by reducing the olfactory sensitivity.SOLUTION: There are provided the CNG channel inhibitor containing a chain monoterpene alcohol expressed by any one of general formulae (1)-(3), the composition for reducing the olfactory sensitivity containing the CNG channel inhibitor and the deodorization method by reducing the olfactory sensitivity by transmitting the CNG channel inhibitor to the nasal chamber before smelling the odor to be deodorized or between before and when smelling.COPYRIGHT: (C)2010,JPO&INPIT【課題】十分な嗅覚感度低下の効果が得られ、しかも眼等に対する刺激の少ない、CNGチャネル阻害剤、これを含有する嗅覚感度低用組成物、及び嗅覚感度の低下による消臭方法の提供。【解決手段】一般式(1)~(3)のいずれかで表される鎖状モノテルペンアルコールからなるCNGチャネル阻害剤、当該CNGチャネル阻害剤を含有する嗅覚感度低下用組成物、及び当該CNGチャネル阻害剤を消臭対象となる匂いを嗅ぐ前に又は嗅ぐ前から嗅ぐ際にかけて鼻腔部に伝達させて嗅覚感度を低下させる消臭方法。【選択図】なし
