Excellent posts, Redneck! The Seuss satire was priceless, and your advice re: dissolution was pretty much spot on. I would definitely not recommend freezing fragrances for the reasons you gave, and will add one of my own: fragrance compounds with very low solubilities may be difficult to get back into solution. I don't know how many fragrance compounds fall into that category but it's not worth taking the chance, IMO. In our lab, we place bottles of precipitated solutions in an ultrasonic bath and zap them for a few minutes to get the precipitate to resolubilize.
