Just curious, have you found 1% dilutions strong enough to evaluate accurately?
This seems to be the opposite of what SoS said. Could you quote where he said this?
I'm wondering if there would be so little of the more volatile ingredients, that they'd disappear off your test trip in a matter of seconds. This could make your more concentrated blends smell differently than your initial experiments. Being able to work at 1% does sound nice though, some of those natural absolutes are expensive!
Are you talking about a component of the fragrance being used at a 1% dilution or the final fragrance composition being evaluated at 1%?
But, yes, if you evaluate a fragrance diluted at 1% dilution versus 10% dilution there will be some difference.
So nobody else is working in such small proportions? Hmm, maybe that's a result of another variation then: do you work on one blend and keep adding more until it works? While I do intend to do that, I also plan to have say, 20 variations of an idea all blended and maturing at once. Sure, most of them may be discarded (or further added to), which is precisely why I want to keep the proportions so small.
I like to have about 4 grams after diluting to about 15% fragrance material in alcohol. I use a scale though and measure the diluted fragrance components by weight.
Your micropipette idea is interesting. But to transfer the liquid from the micropipette don't you have to touch the tip against the container wall, what type of vial will you use.
