Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 toxic effects up to limit of water solubility (<0.05 mg/L)
Key value for chemical safety assessment
Additional information
Data on the acute toxicity of Fatty acids, C8-10, triesters with
trimethylolpropane (CAS 91050-89-4) to aquatic invertebrates are not
available. The evaluation of short-term to aquatic invertebrates refers
to the structural analogue category member Decanoic acid, ester with
2-ethyl-2-(hydroxymethyl)-1,3-propanediol octanoate (CAS 11138-60-6) as
part of a read across approach. The read across is suitable due to the
similar fatty acid chain length of both substances. This is in
accordance with Regulation (EC) No 1907/2006, Annex XI, 1.5. Grouping of
substance and read across approach. Further justification is given
within the endpoint summary 6.1 and within the analogue justification
section 13. The study on the short term toxicity of the read-across
substance Decanoic acid, ester with
2-ethyl-2-(hydroxymethyl)-1,3-propanediol octanoate (CAS 11138-60-6) was
conducted according to OECD guideline 202 as a limit test (Häner, 2007).
Daphnia magna were exposed to the test substance in a static test system
for 48 hours. The test solution was prepared by using the water
accommodated fraction of the test substance. At test termination an EL
50 > 100 mg/L (loading rate) was determined.
Based on the results from structurally related read-across substance (in
accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) which is
characterized by a similar ecotoxicological profile, acute toxic effects
of Fatty acids, C8-10, triesters with trimethylolpropane (CAS
91050-89-4) to aquatic invertebrates are not expected.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 to aquatic
organisms were observed up to the limit of water solubility.
