Description of key information
Acute oral on registered substance.
The purpose of the study was to evaluate the potential toxic effect of the test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) when administered as a single oral dose to Wistar rats. The procedure according to OECD Guideline 423 Acute Toxic Class (ATC) method was used. Available information indicated that the test item is likely to be non-toxic; therefore, a limit dose of 2000 mg/kg was used as a starting dose. Two groups of 3 females were dosed. All 6 females survived the limit dose. The limit dose of 2000 mg/kg did not cause death, evident signs of toxicity or body weight loss during the 14-day long observation period. Based on Annex 2d Test Procedure with a Starting Dose of 2000 mg/kg of OECD Guideline 423 it can be concluded that the LD50 of the test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3 - propanediyl bis(2-hexyldecanoate) is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
An acute dermal toxicity test (OECD 402) was conducted on CAS 62125 -22 -8, a polyol ester member of the category. Test material with no vehicle was placed on clipped skin and occluded. The single dose was 2000 mg/kg bw. Exposure for 24 hours was allowed and then the test material was removed. Daily observations were made for 14 days, with post-dose body weight determinations at 7 and 14 days. No mortality, clinical signs, gross pathology, or body weight effects were noted. Therefore the effect level was > 2000 mg/kg bw.
Thus no hazard for acute oral, inhalation, and dermal toxicity was identified.

Additional information
Several studies are available investigating the acute oral toxicity of polyol esters category members resulting in oral LD50 values greater than 2000 mg/kg bw. Five reliable studies investigating the acute inhalation toxicity within the polyol esters category are available resulting in LC50 values > 5.0 mg/L. Seven reliable acute dermal toxicity studies consistently showed no effects at the limit dose of 2000 mg/kg bw.
Thus, the available data indicate a very low level of acute toxicity for the category members and thus, no hazard for acute oral, inhalation and dermal toxicity was identified.
The category justification is found in IUCLID section 13.
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 category concept is applied to the polyol esters, data gaps will be filled by interpolation, as part of a read across approach from a representative category member(s) to avoid unnecessary animal testing. Additionally, once the category concept is applied, substances will be classified and labelled on this basis. Therefore, based on the group concept, all available data on acute toxicity 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
