In the past, Peru balsam was frequently used in perfumes and cosmetics under the INCI name"Myroxylon pereirae resin".
On the whole, the use of Peru balsam is strongly declining. Instead, extracts or distillates (essential oils) obtained from the raw balsam by high-vacuum dry distillation are used. These extracts have a significantly lower sensitization potential (Geier J 2017).
