Description of key information

In a test according to OECD 316 a theoretical screen (TIER 1) showed a half life of < 190 days. Therefore TIER 2 testing was performed in an Atlas SC 340 Solar Simulator equipped with a metal halide lamp (25 degr C). Samples of irradiated buffered solutions (pH9) taken at 5 time points (upto 11.53 hours exposure) showed degradation of the substance. The main component that degraded was abietic oil with slight degradation of the oleic oil components. T1/2 was 2.88 days.

Key value for chemical safety assessment

Half-life in water:
2.88 d
