Additional information
Justification for grouping of substances and read-across
There are no data available for the acute toxicity of Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol (CAS 92113-48-9). In order to fulfil the standard information requirements set out in Annex VIII, 8.5.2, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from a 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, 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, Fatty acids, C5-10, esters with pentaerythritol (CAS 68424-31-7) is selected as source substance for assessment of acute toxicity by inhalation.

(b) Reference (read-across) substances are indicated in normal font. Lack of data for a given endpoint is indicated by “--“.
The above mentioned substances are considered to be similar on the basis of the similarities in structure, properties and/or activities. The available endpoint information is used to predict the same endpoint for Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol (CAS 92113-48-9).

Discussion
Acute toxicity, oral
Acute oral toxicity was evaluated in a limit test performed according to OECD guideline 423 and under GLP conditions (van Hyegevoort, 2003). Groups of three male and female Wistar rats received a single dose of 2000 mg/kg bw of the test substance by oral gavage. No effects on body weight gain were observed and no abnormalities were found after gross pathology. Since neither clinical signs nor mortality occurred during the 14-day observation period, the LD50 was > 2000 mg/kg bw.
Acute toxicity, inhalation
Acute inhalation toxicity is assessed by using data from the structural analogue Fatty acids, C5-10, esters with pentaerythritol, which was tested in a limit test in accordance with OECD guideline 403 and GLP (Parr-Dobrzanski, 1994). Five male and female Alpk:APfSD rats were exposed nose only for 4 hours to approximately 5.1 mg/L (analytical concentration of the aerosol of the test material). No mortality occurred and no signs of systemic toxicity were observed during the 14-day observation period. Other effects observed (hunched posture, chromodacryorrhoea, piloerection, stains around the nose and wet fur) were noticed during or just after exposure. Body weight gain and lung weight were within normal limits and there were no treatment-related gross pathological findings. Based on these data, the LC50 was estimated to be > 5.1 mg/L air.
Acute toxicity, dermal
No relevant information available.
The physicochemical and toxicological properties of Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol do not suggest potential for a significant rate of absorption through the skin. Therefore, testing by the dermal route is deemed not appropriate.
Conclusion
A LD50 value of >2000 mg/kg bw was observed for the oral route after treatment with Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol. A LC50 >5.1 mg/L was observed after treatment with the analogue substance Fatty acids, C5-10, esters with pentaerythritol after inhalation exposure. In conclusion, Fatty acids, C14-18 and C16-18-unsatd., mixed esters with castor oil, castor oil fatty acids, 2-ethylhexanoic acid and 2,2-bis(hydroxymethyl)-1-butanol is considered to be not acutely toxic via the oral or inhalation route.
Justification for selection of acute toxicity – oral endpoint
There is only one study available.
Justification for selection of acute toxicity – inhalation endpoint
Hazard assessment is conducted by means of read-across from a structural analogue. 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).
Justification for classification or non-classification
Based on substance-specific studies and read-across from structurally similar substances, the available data on the acute oral and inhalation 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.
There are no data available on acute dermal toxicity.
