- Quality of whole database:
- The available information comprises an adequate and reliable study (Klimisch score 2) from a reference substance with similar structure and intrinsic properties. Read-across is justified based on common functional group(s), common precursors/breakdown products, similarities in physico-chemical/exotoxicological/toxicological properties. The selected study is thus sufficient to fulfil the standard information requirements set out in Annex VIII-IX, 8.7, in accordance with Annex XI, 1.5, of Regulation (EC) No. 1907/2006.
Additional information
Justification for read-across
Experimental data on toxicity to reproduction of Fatty acids, C8-10-(even numbered), esters with pentaerythritol and adipic acid are not available. The assessment was therefore based on studies conducted with analogue source substances as part of a read across approach, which is in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. For each specific endpoint the source substance(s) structurally closest to the target substance is/are chosen for read-across, with due regard to the requirements of adequacy and reliability of the available data. Structural similarities and similarities in properties and/or activities of the source and target substance are the basis of read-across. A detailed justification for the analogue read-across approach is provided in the technical dossier (see IUCLID Section 13).
CAS 11138-60-6
Fatty acids, 8-10 (even numbered), di- and triesters with propylidynetrimethanol (CAS 11138-60-6) was tested in a prenatal developmental toxicity study comparable to OECD Guideline 414 (Azuka and Daston, 2004). The test substance was percutaneously applied to Sprague-Dawley rats for 6 h/day under occlusive conditions. 25 animals per sex per dose were treated with 200, 600 or 2000 mg/kg bw/day in corn oil on Days 6-15 of gestation. Control animals (25 per sex per dose) received the vehicle. The middle and the high dose levels caused some local irritation at the site of application, but no decreases in maternal weight gain or food consumption. There were no differences from control in any of the developmental parameters measured, including embryo/fetal viability, fetal weight, malformations, or variations. Therefore, a NOAEL of 2000 mg/kg bw/day was derived for prenatal development and for systemic maternal toxicity. Due to the irritation effects on skin, the local maternal NOAEL was found to be 200 mg/kg bw/day.
Justification for classification or non-classification
According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint". Since the analogue concept is applied to Fatty acids, C8-10-(even numbered), esters with pentaerythritol and adipic acid data will be generated from data for reference source substance(s) to avoid unnecessary animal testing. Additionally, once the analogue read-across concept is applied, substances will be classified and labelled on this basis.
Therefore, based on the analogue read-across approach, the available data on reproductive / developmental toxicity do not meet the classification criteria according to Regulation (EC) No. 1272/2008 and are therefore conclusive but not sufficient for classification.
