Description of key information

Short description of key information on bioaccumulation potential result: 
Basic toxicokinetics: Supporting studies: After 30 minutes, 90% of injected camphene was detected in the respiratory air (human).
Camphene was the only studied terpene in rabbits that produced Glycuronic acid as a metabolite in the urine.
Short description of key information on absorption rate:
Dermal absorption: Supporting studies: Camphene is readily absorbed following a topical application.
After a 30-min full bath with pine oil, one human subject exhaled terpenes, including 0.67 µL camphene, within 5 hr. A constant of 81 µL/cm2/hr was calculated for the percutaneous absorption of camphene from the bath.

Key value for chemical safety assessment

Discussion on bioaccumulation potential result:

Supporting studies: Experimental results: After 30 minutes, 90% of injected camphene was detected in the respiratory air (human). Camphene was the only studied terpene in rabbits that produced Glycuronic acid as a metabolite in the urine. Test method was not according to any guideline.
