Conclusions:

Based on the read-across approach from the analogue substance "Rape oil, bisulfited, sodium salts", the subacute NOAEL for "Fatty acids, C14 -22, ethylene esters, bisulfited sodium sats" was determined to be 1000 mg/kg bw/day for general systemic toxicity.

Executive summary:

The systemic toxic potential and effects on reproduction were assessed in rats following oral administration of the analogue substance "Rape oil, bisulfited, sodium salts" in accordance with OECD Guideline 422 and GLP standards. The oral administration of the test item to rats by gavage at a maximum dose level of 1000 mg/kg/day did not result in any toxicologically significant effects of treatment. The minor effects detected in this study were not considered to represent an adverse effect of treatment; therefore a ‘No Observed Adverse Effect Level’ (NOAEL) was established at 1000 mg/kg/day for systemic toxicity. No treatment-related effects were detected for reproductive performance, hence a ‘No Observed Effect Level’ (NOEL) for reproductive toxicity was considered to be 1000 mg/kg/day. Based on the read-across approach from the analogue substance "Rape oil, bisulfited, sodium salts, the subacute NOAEL for "Fatty acids, C14 -22, ethylene esters, bisulfited sodium sats" was determined to be 1000 mg/kg bw/day for general systemic toxicity..

Justification for classification or non-classification

Based on a read-across, the 28 -day NOAEL (oral, rats) was determined to be 1000 mg/kg-bw/day, therefore, the substance is not classified for STOT-RE according to CLP (Regulation (EC) No 1272/2008), since the NOAEL is higher than the guidance value for Category 2 classification adjusted for a 28 -day duration study (i.e. 300 mg/kg-bw/day).
