Description of key information

Literature provided data for the 4 major components representing about 80% of the UVCB :

Constituent names  CAS nr  Boiling point source
thuyone alpha + beta (at about 60%)  546 -80 -5 / 471-15-8 203°C HSDB
fenchone (at 12%)  1195 -79 -5 204°C EPI suite
sabinene (at 5%) 3387-41-5 142°C EPI suite v4.11

limonene (at 3%)

 5989-27-5

177.6°C

HSDB

       

Key value for chemical safety assessment

Additional information

No study was conducted on the oil iself, as not relevant for an UVCB.

The boiling point of the test item is estimated between 142°C and 204°C.

As no CSA is required for the tonnage band of concern, no key value was retained.
