Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Literature provided data for the 5 major components representing more than 86% of the UVCB substance:

Constituent names  CAS nr  Boiling point source
thuyone alpha + beta (at about 60%)  546 -80 -5 / 471-15-8 203°C HSDB
sabinene (at about 5.5%) 3387 -41 -5 142°C EPI suite v4.11
terpinen-4-ol (at about 2.5%) 562-74-3 209°C HSDB
pinene alpha (at about 2.5%) 80-56 -8 156°C HSDB
myrcene (at about 2.3%) 123-35-3 167°C HSDB

Key value for chemical safety assessment

Additional information

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

The boiling point of the test item is estimated between 142°C and 203°C which are the min and max boiling point of the major constituents.

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