- Remarks on result:
- hydrolytically stable based on preliminary test
- Validity criteria fulfilled:
- not specified
- Conclusions:
- A 5-day test was undertaken to determine the hydrolytic stability of 2-ethylbutyric acid at pH 4 - 9 at 50 °C. At the end of day 5, >90 % substance residue was present and no transformation products were identified, suggesting that 2-ethylbutyric acid is hydrolytically stable in water. A half-life value for hydrolysis was not established.

Description of key information
2-Ethylbutyric acid was concluded to be hydrolytically stable in water over a pH range of 4 - 9 at 50 °C as part of a 5-day study. >90 % of the substance remained and no transformation products were identified. A half-life for hydrolysis was not established.
Key value for chemical safety assessment
Additional information
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.
