Description of key information

The phototransformation in air was estimated by QSAR calculation with AOPWIN v1.92 tool with the CAS number of 8000-41-7 as input.

Key value for chemical safety assessment

Half-life in air:
0.423 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

The phototransformation rate is 1.03E-10 cm3/molecule/sec with OH radicals and 4.3E-16 cm3/molecule/sec with ozone.The calculated global half-life is 0.007 day (0.423 hours). This value is largely below the trigger limit of 2 days as defined in the Convention of Stockholm as POP criterion.

Therefore, Terpineol multiconstituent is not classified as persistent in the troposphere and has no potential for Long Distance Transport through the air.
