[Explain how the model fulfils the OECD principles for (Q)SAR model validation. Consider attaching the QMRF or providing a link]
- Defined endpoint: yes, Oral rat LD50
- Unambiguous algorithm: yes, the algorith is well descriped. see the attached T.E.S.T. User’s Guide, section 1.2 and 2.2
- Defined domain of applicability: yes, see the attached T.E.S.T. User’s Guide, section 3.4
- Appropriate measures of goodness-of-fit and robustness and predictivity: yes, see the attached T.E.S.T. User’s Guide, sections 2.2.1, 2.2.5, 2.2.7, 2.3.1 and 4.4.1
- Mechanistic interpretation: not available
5. APPLICABILITY DOMAIN
[Explain how the substance falls within the applicability domain of the model]
The dataset used in this model contains the same chemical class of the target chemicals. Very similar structural analogues (e.g. similarity coefficient >0.9) were found in the training set and the external test set. Similar test set chemical were predicted well relative to the entire test set. The predicted value matches the experimental values for similar chemicals in the training set
6. ADEQUACY OF THE RESULT
[Explain how the prediction fits the purpose of classification and labelling and/or risk assessment]
Very similar structural analogues (e.g. similarity coefficient >0.9) were found in the training set and the external test set. Similar test set chemical were predicted well relative to the entire test set. The predicted value matches the experimental values for similar chemicals in the training set. The mean absolute error (MAE) of chemicals with similarity coefficient≥0.5 is smaller than the one of the chemicals from the entire set. The predicted LD50 for all constituents are consistent (all values > 2000 mg/kg body weight).

Any other information on results incl. tables
In EPA T.E.S.T., there are experimental data available for the constituents hexadecan-1-ol and octadecan-1 -ol. The LD50 values are 4997.03 and 20010.76 mg/kg, repectively.
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The acute oral toxicity potential in rats is predicted by software EPA T.E.S.T (Toxicity Estimation Software Tool). The LD50 value of the registered substance is considered to be greater than 2000 mg/kg body weight.
- Executive summary:
The acute oral toxicity potential in rats is estimated by software EPA T.E.S.T. (Toxicity Estimation Software Tool). All main constituents were analyzed based on the chemical structures. The LD50 values of all main constituents of the registered substance are greater than 2000 mg/kg body weight. Therefore, the LD50 value of the registered substance is considered to be greater than 2000 mg/kg body weight.
