Key value for chemical safety assessment
Additional information
Since no studies investigating the long-term toxicity of Fatty
acids, C8-10, C8-10 alkyl esters (CAS 129677-93-6) to aquatic
invertebrates are available, in accordance to Regulation (EC) No
1907/2006 Annex XI, 1.5 a read-across to the structurally related source
substance Fatty acids, C8-10, C12-18-alkyl esters (CAS 95912-86-0) was
conducted. The source substance is representative to evaluate the
long-term toxicity of the target substance to aquatic invertebrates. The
target substance is characterized as an ester of C8-C10 fatty acid and
C8-C10 alcohol. The source substance is structurally very similar to the
target substance. Fatty acids, C8-10, C12-18-alkyl esters (CAS
95912-86-0) is a UVCB substance of mainly C8-C10 fatty acid esterified
with mainly C12-C14 alcohol. Comparing both substances they only differ
slightly in C-chain lengths distribution. None of the selected source
substances has a structural alert for an increased toxicity via a
specific mode of action. This read-across is justified in detail in the
overall summary (IUCLID Section 6.1) and within the analogue
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 substance was used for the
assessment.
The study with the read-across substance fatty acids, C8-10,
C12-18-alkyl esters (CAS 95912-86-0) was performed according to OECD 211
(GLP) (Salinas, 2013). Daphnia magna was exposed to a nominal loading
rate of 10 mg/L (Water Accommodated Fraction). Chemical analysis of the
test substance concentrations was not possible since no suitable
analytical method could be developed to detect the test substance. No
effects on reproduction of D. magna were observed up to the water
solubility limit (< 0.05 mg/L) resulting in a NOELR (21 d) ≥ 10 mg/L.
Based on the available results 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, C8-10, C8-10
alkyl esters will not exhibit long-term effects to aquatic invertebrates
up to the limit of water solubility.
