Treemoss lichen extract used as a mossy fragrance base note; the most frequently positive of the EU-26 in patch-test data.

What it does

Evernia furfuracea is an extract of treemoss lichen, used in perfumery for a mossy, resinous base note similar to oakmoss. In a Copenhagen series that patch-tested all 26 EU-declarable fragrance ingredients individually, it was the single most frequently positive. Its main allergens, atranol and chloroatranol, were prohibited in the EU by Commission Regulation (EU) 2017/1410, so treemoss extract remains a declarable EU allergen but can only be used in the EU in a purified, atranol-free grade. Outside the EU there is no such requirement. It is a scent ingredient with no skin function.

The evidence, graded

expert consensusTreemoss (Evernia furfuracea), oakmoss (Evernia prunastri), and HICC (Lyral) were the three most frequently positive of the EU's 26 fragrance allergens in a 1,508-patient patch-test series. Commission Regulation (EU) 2017/1410 prohibited HICC, plus atranol and chloroatranol — the constituents behind most oakmoss and treemoss allergy — from 23 August 2019 for new EU products and 23 August 2021 for stock already on shelves.Heisterberg 2011 · Contact Dermatitis ↗
