Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The hazard assessment is based on the current data available. Based on the ECHA decision on a compliance check (decision number CCH-D-2114546495-41-01/F) from 14 April 2021 a growth inhibition study aquatic plants (OECD 201) is requested. The finalised study will be included into the dossier and the aquatic toxicity will be re-evaluated in the update of this dossier latest by 19 October 2022.

One experimental study investigating the toxicity of decanoic acid, mixed diesters with octanoic acid and propylene glycol (CAS 68583-51-7) to aquatic aquatic is available (Scholz, 1995). As it can be seen in the data matrix of the category justification in section 13 and the overall summary, all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results. The key study was performed according to the EU Method C.3 under GLP conditions (Scholz, 1995). The green algae Scenedesmus subspicatus was exposed to a Water Accommodated Fraction (WAF) of nominal 5.3 mg/L and subsequent dilutions for 72 h. No effects on the growth rate of S. subspicatus up to the limit of water solubility were observed resulting in an ELr50 > 5.3 mg/L and a NOELR of ≥ 5.3 mg/L.
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.
