Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Fatty acids, C8-18 and C18-unsatd., esters with neopentyl glycol (CAS No. 85186-86-3) to algae.
The key study conducted with Fatty acids, C8-18 and C18-unsatd., esters with neopentyl glycol (CAS No. 85186-86-3) was performed as a limit test according to OECD Guideline 201, in a static system (Häner, 2007). During 72 hours, the test organism Desmodesmus subspicatus was exposed to the nominal test concentration of 100 mg/L. The test solutions were prepared as water accommodated fractions (WAF). A stimulation of growth compared to the control was observed. As no inhibition of algal growth was observed, the NOELR (72 h) was reported to be ≥100 mg/L and EC50 > 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 polyol esters category support this hazard assessment by showing a consistent pattern of results, i.e no toxic effects up to the limit 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.
