Fragrance storage and preservation information has always been ambigous to me. Although there is some good information revealed in previous threads on this site, I still wasn't satisfied with any particular method.
Jean Kerleo was the house nose at Patou from 1967 until 1998. He is the founder of Osmotheque, the "living perfume museum" in Versailles.
I contacted Osmotheque to see if they could provide clarification regarding fragrance storage, temperature etc. I told them I kept my fragrances in a refrigerator. Their reply was as follows:
"Exactly. This can appear strange, but you must store your perfume in the rerigerator, safe from light, and in the cold."
They recommend a temperature of 10 degrees celsius for most fragrances, and 4 degrees celsius for citrus fragrances.
It's not getting what you want -- it's wanting what you've got.
Thanks for the info. I guess that means everyone nees 2 fridges (at least) set to different temps!
