Chloroatranol is a natural product that develops in the degradation of another natural component, atranorine, in certain species of fungi (Lethariella cladonioides), mosses (Evernia furfuracea, Evernia prunastri) and lichens ( Platismatia glauca, Cladonia rangiferina).
What it is used for and where
Cosmetics
It is a fragrance with a musky scent.
In the composition of Evernia furfuracea there are two components that have been credited with frequent episodes of sensitisation: atranol (2,6-Dihydroxy-4-methyl-benzladehyde) and chloroatranol (3-Chloro -2,6-Dihydroxy-4-methyl-benzladehyde). These two chemical compounds were banned by European Commission Regulation (EU) 2017/1410 on 2 August 2017:
