Effects on developmental toxicity
Description of key information
Dermal (OECD 414), rat: NOAEL >= 2000 mg/kg bw/day
Effect on developmental toxicity: via oral route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via inhalation route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via dermal route
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The available information comprises an adequate, reliable study (Klimisch score 2) from a reference substance with similar structure and intrinsic properties. Read-across is justified based on common origin, common precursors and breakdown products of hydrolysis and consistent trends in environmental fate, ecotoxicological and toxicological profile (refer to endpoint discussion for further details). The selected study is thus sufficient to fulfil the standard information requirements set out in Annex IX, 8.7, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006.

Effect on developmental toxicity
Justification for grouping of substances and read-across
There are no data available for developmental toxicity of Fatty acids, tall-oil, triesters with trimethylolpropane (CAS 94581-09-6). In order to fulfil the standard information requirements set out in Annex VIII, 8.7.1 and Annex XI, 8.7.2, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substance was conducted.
In accordance with Article 13 (1) of Regulation (EC) No 1907/2006, "information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI are met.” In particular for human toxicity, information shall be generated whenever possible by means other than vertebrate animal tests, which includes the use of information from structurally related substances (grouping or read-across).
Having regard to the general rules for grouping of substances and read-across approach laid down in Annex XI, Item 1.5, of Regulation (EC) No 1907/2006 whereby substances may be predicted as similar provided that their physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity.

The above mentioned substance is considered to be similar on the basis of structural similarity resulting in similar properties and/or activities. The available endpoint information is used to predict the same endpoints for Fatty acids, tall-oil, triesters with trimethylolpropane (CAS 94581-09-6).
A detailed analogue approach justification 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 >= 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.
CAS 67762-53-2
The developmental toxicity of Fatty acids, C5-9, tetraesters with pentaerythritol (CAS 67762-53-2) was investigated comparable to OECD Guideline 414 (prenatal developmental toxicity study) (Feusten, 1988). Groups of 15 presumed pregnant female Sprague-Dawley rats received daily dermal doses of the test substance at concentrations of 800 and 2000 mg/kg bw/day during gestational days 0 to 19. Control animals remained untreated. On day 20 of gestation the animals were euthanized and examined for maternal and fetal parameters. There were no adverse effects found for all parameters examined in maternal animals. Based on the number of implantations, number of total litter losses by resorption, mortality, clinical signs, body weight, gross pathology and organ weights of maternal animals the NOAEL for maternal toxicity was found to be 2000 mg/kg bw/day. Examination of fetus litter size and weights, offspring viability (number alive and number dead), sex ratio, grossly visible abnormalities, external, head, soft tissue and skeletal abnormalities revealed no differences to controls and thus no indication for teratogenic effects. The only effect found was a dose-dependently increased number of fetuses with levocardia, although no hearth malformations have been detected. Furthermore levocardia was observed in vehicle control foetuses (Smith et al. 1988) and in the control foetuses conducted in the test laboratory. Since levocardia was observed in both treated groups, the NOAEL for embryo-/fetotoxicity and teratogenicity in rats Fatty acids, C5-9, tetraesters with pentaerythritol was found to be < 800 mg/kg bw/day and the LOAEL = 800 mg/kg bw/day.
A waiver for the requirement to perform a prenatal developmental toxicity study in a 2ndspecies was included, as this requirement is considered not to add new information for hazard assessment and therefore is scientifically and, considering concerns regarding the use of vertebrate animals for experimental purposes, unjustified.
Justification for selection of Effect on developmental toxicity: via dermal route:
Hazard assessment is conducted by means of read-across from a structural analogue. The available studiy are adequate and reliable based on the identified similarities in structure and intrinsic properties between source and target substances and overall quality assessment (refer to the endpoint discussion for further details).
Justification for classification or non-classification
Based on read-across from the structurally similar substance, the available data on toxicity to reproduction do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
