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.

Description of key information
EC50 (28 d) > 1000 mg/kg dw soil (OECD 216)
Key value for chemical safety assessment
Additional information
To investigate the effects of Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates (CAS No. 91052-13-0) on soil nitrification by soil microorganisms, a GLP study according to OECD Guidelines 216 was performed (Schöbinger, 2013). Nominal concentrations of 100, 178, 316, 562 and 1000 mg/kg soil dw were tested over a time period of 28 days. Compared to the control, no statistically significant effects on nitrogen turnover (measured as NO3 -N level) were observed at any of the test item concentrations 28 days after application. Since no clear dose-response relationship was found, the EC50 was determined to be higher than 1000 mg/kg.
Based on these results, it can be concluded that Glycerides, C8-18 and C18-unsatd. mono- and di-, acetates (CAS No. 91052-13-0) will not cause adverse effects to the nitrogen cycle of the soil at 1000 mg/kg dw soil exposure.
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.
