- Validity criteria fulfilled:
- yes
- Remarks:
- The ECOSAR-Esters equation is valid when using the OECD criteria. In addition, N=20 (+6) and R2 is 0.86
- Conclusions:
- Acute algae toxicity for Oenanthic ether is 0.411 mg/L based on ECOSAR-Ester calculation, using a measured log Kow of 4.6.
- Executive summary:
The acute algae ErC50 for the ester Oenanthic ether is predicted to be 0.411 mg/L based on the ECOSAR SAR for esters using a measured log Kow of 4.6 and the equation: Log 96-h EC50 (mmol/L) = -0.6993 (log Kow) + 0.4715. The 96-h EC50 is considered equivalent to the 72-h ErC50 as defined in OECD TG 20. Though Oenanthic ether is a multi-constituent with alkyl chains varying between C8-C18, a single log Kow was derived in the HPLC, which is thought to be representing the main constituent of Oenanthic ether: Ethyl dodecenoate/laurate and has a C14 chain.
Oenanthic ether is in the applicability domain of the ECOSAR prediction because: a) Oenanthic ether is a chemical class presenting the toxicity solely by its bioavailability (i.e. without fragments that activate this chemical class); b) its log Kow is 4.6 (=< 6.4); c) its MW is < 1000 (< 1000); and; d) the toxicity predicted is below its measured water solubility of 1.6 mg/L.
In accordance with REACH Annex XI, the validity of the (Q)SAR is documented in a QMR for acute algae toxicity on esters (see attached report). The adequate and reliable documentation, presented below, further supports this prediction.

- Executive summary:
The chronic algae ChV for the ester Oenanthic ether is predicted to be 0.245 mg/L based on the ECOSAR SAR for esters using a measured log Kow of 4.6 and the equation: Log 96-h ChV (mmol/L) = -0.5583 (log Kow) - 0.4017. The 96-h ChV is considered equivalent to the 72-h ErC10/NOEC as defined in OECD TG 201. Though Oenanthic ether is a multi-constituent with alkyl chains varying between C8-C18, a single log Kow was derived in the HPLC, which is thought to be representing the main constituent of Oenanthic ether: Ethyl dodecenoate/laurate and has a C12 alkyl chain.
Oenanthic ether is in the applicability domain of the ECOSAR prediction because: a) Oenanthic ether is a chemical class presenting the toxicity solely by its bioavailability (i.e. without fragments that activate this chemical class); b) its log Kow is 4.6 (=< 8.0); c) its MW is < 1000 (< 1000); and; d) the toxicity predicted is below its measured water solubility of 1.6 mg/L.

A 72-h ErC50 and ErC10 values are 0.411 and 0.245 mg/L, respectively, based on ECOSAR prediction using the determined log Kow of 4.6 Ethyl laurate (C12) because it is the main component and it has intermediate chain length.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.411 mg/L
- EC10 or NOEC for freshwater algae:
- 0.245 mg/L
