I fooled around with Phenylethylalcohol lately, when Guy Roberts “Le sens du Parfum” came to my mind again, where he describes Coty’s little trick to bring in oakmoss absolute into his Chypre, without it becoming too dominant in the body, without it covering everything with a sticky oakmoss layer. Coty seemed to have made an oakmoss - ethylalcohol tincture, at boiling temperature equilibrated. Other perfumers and perfumery houses of these times often used phenylethylalcohol as solvent, for instance for benzoin. I was amazed when I read it the first time that Coty boiled his oakmoss. Interesting: Coty basically cooked his crude oakmoss absolute in alcohol, for how long?, what was his oakmoss absolute like? I have to try this once, too. On the other hand…with our modern restrictions on the use of oakmoss there is not much danger anymore of having too much oakmoss in your perfumes.
Here the rought translation of the original text (below)
“Coty realized that the absolute of oakmoss was too monolitic for the use he had in mind in his Chypre and in L’Emeraude. As a matter of fact, Oakmoss absolute is a product with a heavy initial note. It smells in a sense a bit like varnish, but with such a staying power and a strength that it would simply “eat up” the base of any perfume that contains a significant amount of it. He therefore figured out to treat himself the crude oakmoss absolue; dispensing the oakmoss in ethylalcohol and by heating this mixture up to the boiling point….and by filtering it finally. This way he got a product that was the head note of oakmoss, but without its staying power. This, in the case of his Chypre, allowed him this harmonious grouping of the three woody notes, being Sandalwood, Vetiver and Patchouli. Without this little “trick”, the sandalwood and the vetiver would have been completely hidden by the ominpresent oakmoss absolute, and the patchouli would have been too present (dominant)”
“Coty….avait remarquĂ© que les absolues de mousse de chĂŞne Ă©taient des produits trop « monolithiques » pour l’emploi qu’il voulait en faire dans son Chypre et dans l’Emeraude: en effet, la mousse de chĂŞne est un produit au dĂ©part puisant. Il a une sorte d’odeur de vernis, mais d’une tĂ©nacitĂ© et d’une puissance telle qu’elle « dĂ©vorait » le fon des parfums qui en contenaient de façon substantielle. Il imagina donc de traiter lui-mĂŞme la mousse de chĂŞne brute en la faisant baigner dans de l’alcool Ă©thylique et en chauffant ce mĂ©lange jusqu’au Ă©bullition ….en le filtrant aussitĂ´t. Il obtenait ainsi un produit qui Ă©tait la note de tĂŞte de la mousse de chĂŞne, mais qui n’avait pas sa tĂ©nacitĂ©. Cela, dans le cas de son Chypre, lui permit cette harmonieuse association des trois notes « boisĂ©e » que sont le santal, le vĂ©tiver et le patchouli. Sans ce petit « truct », le santal et le vĂ©tiver auraient Ă©tĂ© occultĂ©es par le fond omniprĂ©sent de l’absolue de mousse de chĂŞne, et le patchouli aurait Ă©tĂ© trop prĂ©sent !”
