When did Perfumes start listing allergens on the box?

Hello Parfumo community,

I'm trying to roughly date a bottle of fragrance I purchased recently. I know it's older because the allergens are not listed on the back of the box. It only says alcohol denat, parfum, and aqua. I've also noticed some fragrances, that are perhaps even older? Seem to list the alcohol or fill volume for a fragrance. But it doesn't seem most perfumes have to do that now. I couldn't really find any good info online. Thank you in advance!

Have you tried to insert the batch code to a site like Check Fresh? Most batches can be tracked that way.

I believe most brands tend to repeat their codes every ten years or so, and I believe this bottle could be more than a decade old. I'm really just trying to determine the decade. 

Yeah I would assume the allergen listing is over a decade old thing also. The box and the bottom sticker might give some clues too, for example some brands have slightly changed their name (Thierry Mugler --> Mugler, Paco Rabanne --> Rabanne etc.) or logo font or parent company or factory address etc. I think it could probably be easier to try to determine the age of your fragrance if you told which one it is and added some photos of the bottle and the box.
