Wow. Isocyclocitral. This is probably one of the best odorants I've ever smelled. IFF calls it green/aldehydic/herbal, with a sharp, leafy note. I don't catch the aldehydic part, but admittedly I'm not well-versed in aldehydes. But it is hella-green. The immediate impression that I got when smelling it was "Conifer! It's the perfect conifer top note!" And thegoodscentscompany says it's a pine modifier, so I guess my instinct was on. But as I smell it, I'm thinking of this tree in the backyard of the house growing up, and how I'd break the leaves and what that would smell like. I think it smells like that tree, which may or may not be deciduous (I grew up in Florida, so it might've been, but it didn't lose its leaves in winter; some, like dogwoods, do). Of course, there are also craploads of pines in the backyard, so it could be more conifer than I'm thinking. Essentially, it smells like home.
So now I've smelled cis-3-hexanol, Stemone and now isocyclocitral, and I adore all of them. I'm getting to the point where I could paraphrase what someone said over the weekend about color: "I have a thousand favorite smells, and they're all green!"
