Description of key information

No experimental data on the phototransformation of alpha-Terpineol in air are available. Based on estimation with the QSAR model AopWin alpha-Terpineol undergoes in air rapid degradation after reaction with hydroxyl radicals or ozone. The DT50 -values after reaction with hydroxyl radicals and ozone are 1.25 hours and 0.64 hours, respectively. These values are not considered in the exposure model EUSES/Chesar and therefore no values for the CSA are entered.

Key value for chemical safety assessment
