- Reference substance:
- Phenol, 4-methyl-, reaction products with dicyclopentadiene and isobutylene
- Reference substance:
- Phenol, 4-methyl-, reaction products with dicyclopentadiene and isobutylene
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The screening criteria for P are not fulfilled. Even though no biodegradation has been observed, it cannot be disproved beyond reasonable doubt that the substance is clearly a P / vP as lack of biodegradation observed in the biodegradation test may be due to lack of bioavailability due to the poor water solubility of the substance. The substance is made to function as an anti-oxidant. It can thus be argued that the substance may abiotically degrade in the environment. However, its transformation products have not been assessed, so no definite conclusions can be drawn.
The screening criteria for B are fulfilled as the BCF of 4801.9 is considered as key value for the registered substance following an experimental BMF study, subsequent BCF estimation and a final B assessment. This overall assumption is confirmed by supporting QSAR analysis. For full information please refer to the assessment report attechd in section 13. Accordingly it can be concluded that the substance will bioaccumulate to a significant extent and the substance is assigned with B.
The screening criteria for T are fulfilled because the substance is classified as Repr. 2 in accordance with the CLP Regulation.
