Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Standard sales specification of n-undecanale
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Related composition:
- Undecanal
- Reference substance:
- Standard sales specification of n-undecanale
- Name:
- Undecanal
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Undecanal
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The assessed substance is readily biodegradable indicating that the substance is not a P/vP.
At a tonnage level below 100 t/a (information requirements according to REACH Annex VIII), no data on bioaccumulation are required. However, based on a log Kow slightly above 4.5 (4.8), screening criterion for B under REACH are fulfilled. Based on the BCF of 157 L/kg wet-wt and even based on the maximum value (851.6 L/kg wet-wt) of the range for BCF resulting from QSAR estimation, n-undecanal does not fulfill the B criterion based on BCF (BCF << 2000).
Chronic aquatic toxicity data are only available for freshwater algae. Based on acute aquatic toxicity data available for the three trophic levels, freshwater algae are by far the most sensitive trophic level (EC50 (72 h; growth rate; Pseudokirchneriella subcapitata) = 0.132 mg/L). The chronic EC10 (72h; growth rate; Pseudokirchneriella subcapitata) was determined as 0.049 mg/L (95% CI: 38.5 µg/L – 60.0 µg/L). Accordingly, even the lower 95% confidence limit is above the toxicity criterion of 0.01 mg/L according to REACH Annex XIII. There are no other classifications for human health endpoints which would justify an assessment of n-undecanal as T.
Concluding, n-undecanal clearly does not fulfill the T criterion
