EC number: 306-232-1
CAS number: 96690-38-9
No effects up to the limit of water solubility (OECD 202).
Since no studies investigating the short-term toxicity to fish of
Fatty acids, C16-18, 2-octyldodecyl esters (CAS 96690-38-9) are
available for this endpoint, in accordance to Regulation (EC) No.
1907/2006 Annex XI, 1.5 a read across to the structurally related
category member 2-octyldodecyl isooctadecanoate (CAS 93803-87-3) was
conducted. The read-across substance is characterized by the same
alcohol component (2-octyldodecan-1-ol) and a very similar fatty acid
(C16-18 compared to C18iso (target)). This read-across is justified in
detail in the overall summary (IUCLID Section 6.1) and within the
category justification in IUCLID Section 13. In this case of
read-across, the best suited (highest degree of structural similarity,
nearest physico-chemical properties) read-across substances were used
for the assessment. Nevertheless, 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 study
with the read-across substance 2-octyldodecyl isooctadecanoate (CAS
93803-87-3) was conducted according to OECD 202 (GLP) with the water
flea Daphnia magna (Bogers, 1998). A Water Accommodated Fraction (WAF)
of nominal 86 mg/L was prepared and tested under static conditions
(limit test). A chemical analysis of the test substance concentrations
in the test vessels was not possible since no applicable method could be
established due to the very low water solubility to detect test
concentrations. No immobilisation was observed after 48 h and therefore
an EL50 of > 86 mg/L was derived.
Based on the available result from one 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 and comparable structure, it can be concluded that Fatty acids,
C16-18, 2-octyldodecyl esters will not exhibit short-term effects to
aquatic invertebrates up to the limit of water solubility.
