Abstract:
Oak moss absolute, an extract from the lichen Evernia prunastri , is a valued perfume ingredient but contains extreme allergens. Objectives To compare the elicitation properties of two preparations of oak moss absolute: ‘classic oak moss’, the historically used preparation, and ‘new oak moss’, with reduced contents of the major allergens atranol and chloroatranol. Patients/materials/methods The two preparations were compared in randomized double‐blinded repeated open application tests and serial dilution patch tests in 30 oak moss‐sensitive volunteers and 30 non‐allergic control subjects. Results In both test models, new oak moss elicited significantly less allergic contact dermatitis in oak moss‐sensitive subjects than classic oak moss. The control subjects did not react to either of the preparations. Conclusions New oak moss is still a fragrance allergen, but elicits less allergic contact dermatitis in previously oak moss‐sensitized individuals, suggesting that new oak moss is less allergenic to non‐sensitized individuals.
