Description of key information
Isopropyl myristate is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Three studies are available on biodegradation with the substance Isopropyl myristate. Ready biodegradability of Isopropyl myristate was tested in a CO2-evolution test according to OECD 301B and to GLP (King 1993). The biodegradation of 9.45 mg/L DOC (nominal) of the test substance was monitored for 28 days. After 28 days, 91.4% of the initial test substance was degraded. This is in consistence with another supporting study where 10 to 20 mg/L DOC were degraded to 81.7 and 90% respectively after 28 days (equivalent to OECD 301B)(Weston 1979). A third study found inherent biodegradability in a CO2 evolution test according to OECD 301B (Andeweg 1988).
The results are in consistence with all further members of the category for which ready biodegradability was observed. Based on the reported studies and supported by results in the category Isopropyl myristate is considered to be readily biodegradable.
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.
