Photosensitivity to musk ambrette

Abstract

Photosensitivity to musk ambrette was confirmed in 15 men previously photopatch tested and in a further 4 men currently attending the clinic. Six of the recalled patients continued to react adversely to sunlight due either to unrecognized exposure to musk ambrette or to their having become persistent light reactors. Positive photopatch tests, possibly cross reactions, were seen in 3 of the 19 patients with the structurally-related nitromusks, moskene and musk xylene but not with musks ketone and tibetine. Musk ambrette elicited a positive patch test without light in 3 of the 19 patients.
