EC number: 306-232-1
CAS number: 96690-38-9
The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to investigate further the toxicity to terrestrial arthropods.
In accordance with Regulation (EC) No. 1907/2006, Annex IX, column
2, 9.4 further studies on the effects on terrestrial organisms do not
have to be conducted since the chemical safety assessment indicates that
there is no need. No experimental data on toxicity to terrestrial
arthropods are available for fatty acids, C16-18, 2-octyldodecyl esters
(CAS 96690-38-9). The test substance is characterised by a high log Koc
indicating a considerable potential for adsorption to soil particles.
Therefore, tests with soil-dwelling organisms that feed on soil
particles are most relevant for the evaluation of soil toxicity of fatty
acids, C16-18, 2-octyldodecyl esters.
Read-across in accordance to Regulation (EC) No. 1907/2006 Annex
XI, 1.5 from the structurally related category member 2-octyldodecyl
isooctadecanoate (CAS 93803-87-3) resulted in no toxicity to terrestrial
macroorganisms (NOEC (56 d) ≥ 1000 mg/kg soil dw).
Moreover, no acute and chronic effects were observed in the
available aquatic studies. Exposure of the soil compartment is generally
considered to be low. Even if exposed to the soil the LCAE category
members are readily biodegradable indicating that they will not be
persistent in the environment. Indirect exposure via irrigation or
atmospheric transport is considered to be negligible based on the
physico-chemical properties of the LCAE category members (water
solubility:< 1 mg/L or even < 0.05 mg/L;vapour pressure: <0.0001 Pa
(minimum) - 0.11 Pa (maximum)).
Thus, the available data investigating the toxicity to terrestrial
macroorganisms are sufficient to assess the hazard of fatty acids,
C16-18, 2-octyldodecyl esters to terrestrial organisms.
