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.
Experimental data on the toxicity of Fatty acids, C16-18 (even
numbered) and C18-unsatd., branched and linear, di and triesters with
trimethylolpropane (EC-No. 931-531-4) to terrestrial arthropods are not
available. In accordance with Regulation (EC) No. 1907/2006, Annex IX,
column 2, 9.4 further studies on the effects on terrestrial organisms
does not have to be conducted since the chemical safety assessment
indicates that there is no need.
The TMP esters of the polyol esters category are characterised by
a high Koc indicating a high potential to adsorb to soil particles.
Therefore the substances might be ingested by soil-dwelling organism
feeding on soil particles. However, the members of the TMP ester group
are in all probability not acutely toxic as indicated by the available
studies on the acute toxicity of the TMP esters to aquatic organisms. A
chronic exposure of terrestrial organisms is not probable since the
members of the TMP ester group are readily biodegradable. Thus, they can
be expected to be rapidly and ultimately degraded in the terrestrial
environment. When ingested by soil dwelling organisms, TMP esters are
expected to be rapidly metabolised and thus an accumulation and/or
chronic effects are not likely. Two earthworm reproduction tests
according to OECD 222 are available for the TMP esters
2-ethyl-2-[[(1-oxoheptyl)oxy]methyl]propane-1,3-diyl bisheptanoate (CAS
78-16-0) and 2-ethyl-2-(((1-oxoisooctadecyl)oxy)methyl)-1,3-propanediyl
bis (isooctadecanoate) (CAS 68541-50-4). In both studies no chronic
toxicity of the substances to Eisenia fetida was determined (Eisner,
2013). The substances caused neither mortality nor a decrease in body
weight of adult earthworms. Also the reproduction rates were not
affected by the TMP esters and thus a NOECmort/repro 1000 mg/kg was
reported in both studies.
In accordance with Regulation (EC) No. 1907/2006, Annex X, 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
toxicity to terrestrial arthropods is not expected to be of concern.
