It may be important to distinguish atranorin and chloroatranorin.
Of chemicals relevant for sensitization, a typical industrial treemoss absolute oil (which is also an extract) may contain approximately 0.36% atranol, 0.22% chloratranol and 5-6% dehydroabietic acid and other resin acids (including the allergenic 7-oxodehydroabietic acid), but undetectable levels of atranorin and chloroatranorin, as these are easily degraded into atranol and chloroatranol (20).
