I’m not sure if you’ve had a look at my site, but I remember writing about my Equisetum fragrance (a classic masculine aromatic FougŤre) that it has ‘maximum permitted levels of oakmoss’, which it does. When I designed it originally it was for a commission (in the end the client chose something else, so I was free to market Equisetum) and the original design had a lot more oakmoss - about 10 times as much in fact - for the retail product I had to replace most of it with a synthetic substitute.
The point of this ramble is that I’ve been wondering about putting a note on the site to say that you can have the original, non-compliant, formulation if you specifically request it. My thinking being that a specific request like that would constitute consent to exposure to more than the usual amount of the potential allergen and so protect me from lawsuits. I’m not sure whether there is really that much market for it though - other than a few Basenotes aficionados that is.
