Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No effects up to the limit of water solubility for Desmodesmus subspicatus (OECD 201)
Key value for chemical safety assessment
Additional information
One study is available on the toxicity of 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4) to algae.
The key study conducted with 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4) was performed as a limit test according to OECD Guideline 201 (Häner, 2006). The test organism Desmodesmus subspicatus was exposed to the test substance in a static system for 72 hours, at the nominal test concentration of 100 mg/L. No significant effects on algae were observed during the study and the EL50 value was reported to be > 100 mg/L. The NOELR was reported to be≥100 mg/L.
As it can be seen in the data matrix of the category justification in section 13 and the overall endpoint summary IUCLID 6.1, all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results, i.e. no toxic effects up to the limit of water solubility.
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.
