Key value for chemical safety assessment
Effects on fertility
Effect on fertility: via oral route
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The available information comprises an adequate and reliable study (Klimisch score 2 due to read-across) from a reference substance with similar structure and intrinsic properties. Read-across is justified based on common precursors/breakdown products (refer to endpoint discussion for further details). 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.
Effect on fertility: via inhalation route
- Endpoint conclusion:
- no study available
Effect on fertility: via dermal route
- Endpoint conclusion:
- no study available

Justification for grouping of substances and read-across
There are no data available on the toxicity to reproduction of Multi constituent ester of pentaerythritol 2-ethylhexanoate. In order to fulfil the standard information requirements set out in Annex VII-IX in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substances 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, 1.5, of Regulation (EC) No 1907/2006, whereby physicochemical, toxicological and ecotoxicological properties may be predicted from data for reference substance(s) by interpolation to other substances on the basis of structural similarity,Hexanoic acid, 2-ethyl-, 2,2-bis [ [(2-ethyl-1-oxohexyl)oxy] methyl] -1,3-propanediyl ester(CAS 7299-99-2) is selected as source substance for assessment of toxicity to reproduction.

(b) Reference (read-across) substances are indicated in normal font.
The above mentioned substances are considered to be similar on the basis of same precursers/breakdown products. The available endpoint information is used to predict the same endpoint for Multi constituent ester of pentaerythritol 2-ethylhexanoate (CAS Former 7299-99-2).
A detailed analogue approach justification is provided in the technical dossier (see IUCLID Section 13).
Furthermore, based on exposure considerations no further data for the endpoints “Repeated dose toxicity” and “Toxicity to reproduction” were included in the dossier. A substance-tailored exposure-driven testing was followed for the hazard assessment of toxicity to reproduction. No significant exposure is expected throughout all relevant exposure scenarios according to Annex XI, section 3.2(a) (i), therefore testing for toxicity to reproduction is omitted in accordance with Annex VIII column 2 section 8.6.1. The justification is based on an exposure assessment in accordance with section 5 of Annex I.
Further details are given in the endpoint itself, as well as in the chapter "Toxicological information" and in chapter 9 and 10 of the CSR.
Discussion
A combined repeated dose toxicity study with the reproduction/developmental toxicity screening test was performed according to OECD 422 and in compliance with GLP (MHWL, 2005). Twelve male and 12 female Crj: CD(SD) rats per dose were treated by gavage with 100, 300, and 1000 mg/kg bw/day ofHexanoic acid, 2-ethyl-, 2,2-bis [ [(2-ethyl-1-oxohexyl)oxy] methyl] -1,3-propanediyl ester. Male rats and additional 5 female rats (recovery animals of control and 1000 mg/kg bw/day dose group) were dose once daily for 42 days. The other females were treated from day 14 before mating to day 4 of lactation. There was no substance-related mortality and no clinical signs that were related to treatment were observed during the study period. No effect on body weight gain was observed. No treatment-related effects were observed regarding organ weights, clinical chemistry and pathology. No substance-related effect on the oestrus cycle was observed. No effect on the reproductive performance of the parental animals was observed. No effect on viability was observed in the offspring. In addition no clinical findings, effects on body weight, and no effects at necropsy were observed in the offspring. In conclusion, the NOAEL was ≥ 1000 mg/kg bw/day for maternal toxicity as well as reproductive toxicity.
Conclusion
The results of the OECD 422 study with the surrogateHexanoic acid, 2-ethyl-, 2,2-bis [ [(2-ethyl-1-oxohexyl)oxy] methyl] -1,3-propanediyl esterthat no reproductive toxicity is anticipated for Multi constituent ester of pentaerythritol 2-ethylhexanoate. Thus, a NOAEL of ≥ 1000 mg/kg bw/day was concluded for Multi constituent ester of pentaerythritol 2-ethylhexanoate.
Short description of key information:
An OECD 422 study (MHWL, 2005) with the surrogate pentaerythritol esters with 2-ethylhexanoic acid is available, where no adverse effects were found regarding reproductive and developmental toxicity, revealing a NOAEL of 1000 mg/kg bw (highest dose tested).
Justification for selection of Effect on fertility via oral route:
Hazard assessment is conducted by means of read-across from a surrogate. The selected study is the most adequate and reliable study based on the identified similarities in structure and intrinsic properties between source and target substance and overall assessment of quality, duration and dose descriptor level (refer to the endpoint discussion for further details).
Effects on developmental toxicity
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 study available
Additional information
A substance-tailored exposure-driven testing was followed for the hazard assessment of toxicity to reproduction. No significant exposure is expected throughout all relevant exposure scenarios according to Annex XI, section 3.2(a) (i), therefore testing for toxicity to reproduction is omitted in accordance with Annex VIII column 2 section 8.6.1. The justification is based on an exposure assessment in accordance with section 5 of Annex I.
Further details are given in the endpoint itself , as well as in the chapter "Toxicological information" and in chapter 9 and 10 of the CSR.
Justification for classification or non-classification
The available data on toxicity to reproduction of the substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
