PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl acetate
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- (1R,2S,5R)-2-isopropyl-5-methylcyclohexyl acetate
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2014).
Persistence
In a valid hydrolysis study in accordance with OECD guidelines the read-across substance menthyl acetate was found to hydrolyse under environmental conditions with a half life of 133 h at 25 °C and pH 7 which is far below the P(vP) trigger criterion of T1/2 > 40 (60) days) for the PBT discussion. The expected products of hydrolysis L-menthol and acetic acid are readily biodegradable. The substance is therefore not (v)P.
Bioaccumulation
The substance has a log Kow of 4.39 (OECD 123). Thus, the substance does not meet the screening criterion for bioaccumulation (log Kow ≥ 4.5) and it is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
A long-term toxicity result for Pseudokirchneriella subcapitata is available with an ErC10 (72 h) of 0.61 mg/L (measured). Moreover, the substance is not classified for human toxicity according to Annex XIII of Regulation (EC) No 1907/2006 based on Regulation (EC) No 1272/2008 (6th ATP). Thus, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not met and the substance is not considered to meet the T criterion.
In conclusion, the substance is not considered to be PBT or vPvB.
Reference
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.
