Perfume

===Safety regulations===
The US FDA controls the safety of perfumes through their ingredients and requires that they be tested to the extent that they are [[Generally recognized as safe]] (GRAS). Due to the need for protection of trade secrets, companies rarely give the full listing{{citation needed|date=February 2023}} of ingredients regardless of their effects on health.{{doubtful|date=February 2023}} 

In the EU, as from 11 March 2005, the mandatory listing of a set of 26 recognized fragrance allergens was enforced.<ref>{{cite web|url=http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:066:0026:0035:EN:PDF|title=DIRECTIVE 2003/15/EC|website=Eur-lex.europa.eu|access-date=19 February 2018|archive-date=21 May 2019|archive-url=https://web.archive.org/web/20190521031743/https://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:066:0026:0035:en:PDF|url-status=live}}</ref> The requirement to list these materials is dependent on the intended use of the final product. The limits above which the allergens are required to be declared are 0.001% for products intended to remain on the skin, and 0.01% for those intended to be rinsed off. This has resulted in many old perfumes like chypres and [[fougère]] classes, which traditionally make use of oakmoss extract, being reformulated.{{Citation needed|reason=It would be nice with a citation showing that that’s the reason they got reformulated.|date=September 2022}}
