Why lemon is gone from my strip by lunch

Lemon is all top note. Wikipedia's article on perfume notes puts citrus among the small, volatile molecules you smell first and lose first.

Citrus is the treble of a perfume. First to arrive, first to go.

The notes article ranks materials on an evaporation scale where top notes sit at 1 to 14, the quick end, and base notes at 61 to 100. The club's Class on top, heart and base notes has a strip test that shows it over a whole day. Lemons are dropping off the backyard tree this arvo, so I've got no excuse.

Makes sense. So is there any way to make it stay?

Not by buying stronger, sadly. The club's Class on fragrance concentrations says a scent built mostly on citrus is likely to stay brief even as an extrait.

It's like a bright glaze over a dark clay body. The bright part is what you see first, the body is what's still there after the firing.

Did the strip test from that Class: lemon peel on one, vanilla on another. Lemon gone by lunch again, vanilla still there at teatime. Point taken.
