Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Experimental data on
the acute toxicity of Fatty acids, C16-18 and C18-unsatd., hexaesters
with dipentaerythritol (CAS 68604-38-6) are available for fish. The
short-term toxicity of the substance to Zebra fish (Danio rerio) was
tested in a GLP guideline study according to OECD guideline 203 (Caduff,
2013). A LL50 (96 h) >100 mg/L based on nominal concentrations was
determined (NOEC ≥ 100 mg/L). Thus a toxic effect of the substance was
not observed up to the limit of water solubility (< 0.15 mg/L). The
long-term toxicity of the substance to Daphnia magna was tested in a
guideline study following OECD 211 (Caduff, 2013). An effect on survival
or reproduction rate of the daphnids was not observed within the limit
of water solubility (NOEC (21 d) ≥ 100 mg/L). Data on short-term
toxicity to aquatic invertebrates and algae and long-term toxicity to
fish are not available. However, the available acute and chronic
toxicity tests demonstrate that toxic effects of the substance up to the
limit of water solubility are unlikely. Therefore further acute and
chronic testing is omitted.
Data on the toxicity to microorganisms was derived from the toxicity
control of the biodegradation study according to OECD 301B (Caduff,
2012). A respiration inhibition of activated sludge was not observed and
thus the substance concentration of 20 mg/L was used as NOEC. In
conclusion, Fatty acids, C16-18 and C18-unsatd., hexaesters with
dipentaerythritol (CAS 68604-38-6) exhibits no toxic effects on
freshwater organisms up to the limit of the water solubility of the test
substance (WS < 0.15 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
