PBT assessment: overall result

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

In a study conducted according to OECD Guideline 301F, hydroxycitronellol  proved to be readily biodegradable (70-80% biodegradation after 28 d; 80-90% biodegradation after 35 d). No significant persistence in environmental compartments is to be expected.

A log Pow of 1.59 at 25°C determined in a study conducted according to EU Method A.8. indicates a low potential for bioaccumulation in aquatic organisms, which is supported by the low calculated BCF of ca. 22 L/kg determined with Kow. Consequently, no significant potential for bioaccumulation in aquatic organisms is to be expected for the test item.

Based on the results on short- and long-term toxicity of hydroxycitronellol to aquatic organisms, the lowest (L(E)C50 from short-term toxicity testing was determined to be > 100 mg/L and the lowest NOEC from long-term toxicity testing was determined to be >=100 mg/L. These data indicate that the test item is not to be regarded as a substance exhibiting PBT or vPvP properties according to the criteria of REACH Directive, Article 14.3 (d) and the Technical Guidance Document (TGD) R.11 of the European Chemicals Agency.
