This phenomenon seems to play a role in photosensitivity maintenance, particularly in cases involving certain classical allergens that have a high phototoallergic poten-tial, such as tetrachloro salicylanilide, musk ambrette, sulfanila-mide, lichen acid mix, and P-aminobenzoic acid (5), (9).
Some fixatives are oils such as patchouli, sage and sandalwood; balsams, gums and oleoresins such as benzoin, myrrh and oakmoss; and synthetics such as vanillin,
musk ambrette, benzyl cinnamate and ethyl phthalate.
