Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
EC50 (72 h) = 632.5 mg/L for Skeletonema costatum (ISO 20253:2006)
Key value for chemical safety assessment
Additional information
One experimental study investigating the toxicity of Reaction mixture of Glycerol 1,3- di(acetate), glycerol acetate and triacetin to marine algae is available (Manley, 2002). The study was conducted according to ISO 10253:2006(E) under GLP conditions using the marine algae Skeletonema costatum. Five concentrations up to a maximum of 1000 mg/L (nominal) were tested in a static exposure regime. The lowest concentration of 100 mg/L did not result in any effects on the growth rate whereas inhibitory effects were observed at higher concentrations after 72 h. Thus, a NOEC of 100 mg/L and an EC50 of 632.5 mg/L were derived.
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.
