Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation, other
- Remarks:
- (Q)SAR
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- This endpoint study record is a QSAR prediction. The prediction of the skin sensitisation potential of m-toluic acid is sufficient to fulfil the information requirements as further explained in the provided endpoint summary. The reliable documentation of the applied method (QMRF) and the prediction (QPRF) is attached under “Attached justification” in this endpoint summary.

- no indication of skin sensitisation based on QSAR/QSPR prediction
Any other information on results incl. tables
Skin Sensitization model (CAESAR) - v. 2.1.6 predicted that m-toluic acid may not have skin sensitisation potential
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the model outcome “m-toluic acid” is considered as a non-sensitising substance in the sense of Regulation (EC) No 1907/2006. The substance under concern is within the applicability domain of the “VEGA - Skin Sensitisation model (CAESAR) – v.2.1.6”. Hence, the prediction is fully reliable to replace an in vivo skin sensitisation test to fulfill requirements for Regulation (EC) No 1907/2006 (REACH) Annex VII section 8.3.
