Let’s take a look at IFRA/EU restrictions on oakmoss, the future of chypres, the reasons why fragrance houses are eschewing chypres, fractional distillation to remove IFRA-forbidden allergens, the use of seaweed to supplement or create an oakmoss base, the type of oakmoss that suppliers make available to perfume houses, and how the fear of still more restrictions in the future is impacting the types of scents that perfume houses are making. A fascinating, highly informative discussion of these issues took place last night on Twitter with several experts chiming in to explain what is going on behind the scenes and its significance. I learnt a considerable amount, particularly regarding the type of oakmoss currently on the market, and I’d like to share that with you here.
