Key value for chemical safety assessment

Additional information

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

The vapour pressure of the test item is estimated between 0.0502 mmHg and 7.36 mmHg.

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