I recently commissioned a raw GCMS analysis of Frederic Malle's 'Portrait of a Lady'.
Looking it over and comparing it with various GCMS' of Bulgarian Rose, I'm guessing there is 4-6% real Bulgarian Rose (Rosa damascena) in the formula.
I just need a sense check for those who are also familiar with this perfume. Does that amount sound right? It seems to me to be a lot real rose (and expensive!)
