PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

The substance has shown to be inherently biodegradable and thus is not considered persistent. Furthermore as homosalate hydrolyses quite fast under environmental conditions (pH7) with a half-life of only 9 days, the substance can be regarded as rapidly degradable under environmental conditions. With a half-life time of < 16 days the criteria for rapid degradation according to the CLP/GHS criteria are as well fulfilled as the degradation products salicylic acid (2-hydroxylbenzoic acid) [CAS 69-72-7] and 3,3,5-trimethylcyclohexanol [CAS 116-02-9] are not classified as hazardous to the aquatic environment. A persistence of homosalate in the environment is therefore not expected.

In the absence of persistency, a substance can neither be considered vPvB nor PBT and hence further studies investigating bioaccumulation potential are not needed.

However, the bioaccumulation potential was estimated by QSAR and found being 224.4 L/kg ww and thus not considered critical.

No indications were found for the toxicity criterion as also aquatic toxicity is void within limitations of water solubility and the substance is not considered CMR or having chronic effects that could be seen in repeated dose studies.
