PBT status:
the substance is not PBT / vPvB
Justification:

TOPP is a UVCB substance; it consists of a mixture of terpenes, mainly consisting of bicyclic monoterpenes such as α- and β-pinene and δ-3-carene, monocyclic monoterpenes (e.g. dipentene) and sesquiterpenes.

A key issue for the risk assessment of UVCB substances is the possibility that even though the substance has passed a ready biodegradability test, it might contain some persistent (‘P’) or very persistent (‘vP’) constituents. Furthermore, some of these constituents could be bioaccumulative (‘B’) or very bioaccumulative (‘vB’), or toxic (‘T’). Therefore, the possibility that some ‘vPvB’ or ‘PBT’ constituents are present in the substance is investigated.

The REACH Regulation requires that registered substances are evaluated to determine whether they have properties that confer on them the status of being of “very high concern (sVHC)” or, in the cases of UVCB substances, whether they contain any constituents identified as such at a concentration of >0.1%.

It should be noted that some samples of TOPP may differ in composition to the one considered in detail here.

Based on the available information on the constituents present in TOPP, it can be concluded that none of the constituents fulfil the criteria of PBT or vPvB.

TOPP and its constituents do not meet the criteria for PBT; therefore, emission characterisation is not required.
