Description of key information
The partition coefficient n-octanol/water (Log Kow) of C4 acrylate was determined to be 4.19 at 22 °C using EPA OPPTS 830.7550 (Partition Coefficient, n-octanol / H2O, Shake Flask Method) and OECD 107 “Partition Coefficient (n-Octanol/water): Shake Flask Method”.
Key value for chemical safety assessment
Additional information
The partition coefficient n-octanol/water of C4 acrylate was measured based on U.S EPA guidance document OPPTS 830.7550 “Partition Coefficient (n-Octanol/Water), Shake Flask Method” and OECD 107 “Partition Coefficient (n-Octanol/water): Shake Flask Method”, and was conducted under GLP. C4 acrylate was shaken in octanol/water mixture ratios of 1:1, 1:2 and 2:1 at 22 °C for approximately 6 days. The aqueous and n-octanol phases were separated by centrifuging and transferred to individual vials. C4 acrylate in octanol phase and aqueous phase were analyzed separately using LC/MS/MS. The log Kow of C4 Acrylate was determined to be 4.19 at 22.2 (±1.0)°C and at a pH of 6.8 (±0.3).
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.
