Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification
Official classification regarding environmental hazards
Aquatic compartment
No data were found for the substance concerning Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2.
Self-classification
Aquatic compartment
Following DSD/DPD, the substance is not to be classified as dangerous for the environment.
Rationale:
- The lowest effect value for acute toxicity to aquatic organisms (LC/EC50) is higher than 1 mg/L.
- The substance is readily biodegradable and the log Pow is <3.
Following GHS, the substance is not to be classified as acutely or chronically hazardous to the aquatic environment.
Rationale:
The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
Chronic data are not available for the substance; therefore, classification is based on the available acute toxicity data.
- Acute toxicity data:
Acute data are available for fish (96 LC50 =50 mg/L), algae (72 -h ErC50 = 240 mg/L), daphnia (48 -h EC50 = 350 mg/L). The lowest EC50 was determined for fish (EC50 = 50 mg/L), the substance is rapidly degradable and the log Pow is < 4. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as chronically or acutely hazardous to the aquatic environment.
- Ethylene oxide (EO) is only used as an intermediate or as a monomer in polymer production. Both uses are performed in closed systems and under strictly controlled conditions. Unintended releases into the environment are hence not to be expected. Additionally, regular external audits of the facilities, conducted by the national competent authority of the respective country in Europe or an independent organization, ensure that the measured values of air around the highly contained facilities do not exceed the legally permitted thresholds. Therefore, environmental exposure is negligible.
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.
