“…We decided to carry out another patch test with a special professional series for archery made by FIRMA (usnic acid 1%, wood tar mix 12%, 5% pine oil, turpentine 20%, turpentine peroxides 0.3%, 10% creosote, beeswax 30%, urea formaldehyde resin 10%, phenol formaldehyde resin 5%, δ-3-carene, α pinene 15% olive oil, dammar resin 20%, sesquiterpene lactone mix 0.1%, colophony 20%, balsam of Peru 25%, formaldehyde 1% water, 0.5% potassium dichromate, epoxy resin 1%, p tert-butylphenol formaldehyde 1%), with a positive reaction (+) for wood tar mix 12% at 48 and 72 h, like another case we described 1. In order to further investigate the haptens present in wood tar mix, we employed another FIRMA professional special series for wood tar mix (phenol 0.5%, m-cresol 2%, creosote 10%, pyrocathecol 2%, a-pinene 15%, S-limonene 2%, R-limonene 2%, sesquiterpene lactone mix 0.1%, diptene 1% acetone).…”
