Summary
2455 consecutive patch test patients were tested to two separate fragrance mixes: one the standard 8% Hermal/Larsen fragrance mix and the other a new 9.5% Hausen mix containing dihydrocoumarin and citral but excluding oak moss and amyl cinnamaldehyde. The overall incidences of allergy to fragrance materials as measured by these mixes were 7.8% and 6.7%, respectively. There was relatively poor concordance between the mixes which could not be explained only by their different composition. False-positive reactions and false-negative reactions occurred with both types of mix. The 9.5% Hausen mix gave rather more unexplained positive results but both dihydrocoumarin and citral were found to give significant numbers of positive reactions.
