PBT assessment
Administrative data
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
