- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008.
- Conclusions:
- The observation period was only 6 days. However, as no clinical signs were observed and the body weight development was described to be normal, it is unlikely that mortality would have occurred in the time period Day 7-14. The study is therefore considered to be sufficient to meet the data requirement and the LD50 is considered to be > 2000 mg/kg bw.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
- Quality of whole database:
- The available information comprises an adequate and reliable study from a reference substance with similar structure and intrinsic properties. Read-across is justified based on 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 sufficient to fulfil the standard information requirements set out in Annex VIII, 8.5, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006.
Additional information
Justification for read-across
Data on the acute dermal toxicity of Dub TGI 24 are not available. The assessment of acute dermal toxicity was therefore based on a study conducted with a source substance 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).
Acute oral toxicity
CAS 91052-08-3
The acute oral toxicity of Dub TGI 24, was assessed in a study performed following a protocol similar to OECD guideline 401 (please refer to IUCLID section 7.2.1). No individual animal data was given. Five male SPF NMRI mice were administered 2000 mg/kg bw by gavage. No mortality was observed during the 6-day observation period. No treatment-related clinical signs were observed. The body weight increase was reported to be ‘normal’. Based on the results, the oral LD50 value for male mice is > 2000 mg/kg bw.
Acute dermal toxicity
CAS 555-43-1
The acute dermal toxicity of glycerol tristearate was investigated in a limit test performed according to OECD guideline 402 and under GLP conditions (please refer to IUCLID section 7.2.3). 2000 mg/kg bw test substance dissolved in corn oil was applied to the shaved skin of 5 Wistar rats/sex for 24 h under semiocclusive conditions. After exposure, residual test substance was removed and animals were observed for a period of 14 days. No mortality occurred and no clinical signs were reported. Four female rats showed minimal body weight gain after the first week. One female had a body weight loss (-3.2%) after the first week. At the end of the study, minimal body weight gain was recorded in two female animals and one animal showed no body weight gain. Two female rats achieved satisfactory body weight gains throughout the study. The observed variation in body weight was limited to less than 10% and not considered to be treatment-related. The body weight gain during the study period of the male animals was within the normal range for this species and strain. No local skin effects were observed at the test site. At necropsy, no substance-related findings were noted. Therefore, the LD50 in male and female rats is > 2000 mg/kg bw.
Acute inhalation toxicity
No data on acute toxicity following inhalation are available. Based on the vapour pressure of the substance and the defined uses, no study needs to be conducted because exposure of humans via inhalation is not likely.
Overall conclusion for acute toxicity
The reliable data available for the target and source substances indicate a very low level of acute toxicity following the oral and dermal route, as LD50 values were greater than the currently applied limit values. Therefore, as the available data did not identify any hazard for acute toxicity, Dub TGI 24 is not expected to be hazardous following acute exposure.
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 Dub TGI 24, data will be generated from data available 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.
The available data on acute toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
