EC number: 278-137-2 | CAS number: 75214-69-6
Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation, other
- Remarks:
- QSAR
- Type of information:
- (Q)SAR
- Adequacy of study:
- weight of evidence
- Study period:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- 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:
- 1. SOFTWARE
QSAR dyes R&C version 5.2 on 10-11-17
2. MODEL (incl. version number)
QSAR skin sensitization (v. 2.0)
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
EC No.: 278-137-2
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
- Defined endpoint: Skin senitisation
- Unambiguous algorithm: The developed model is based on locàl similàrity based on à set of molecular descriptors
- Defined domain of applicability: A model report is provided informing about the limitations of eàch prediction in its structural domain and response space.
- Appropriate measures of goodness-of-fit and robustness and predictivity: Procedures to understand if the model is able to reliàbly predict skin sensitization for external test samples were properly applied.
- Mechanistic interpretation: see attachment
5. APPLICABILITY DOMAIN
see attachment Skin Sensitzation QSAR Model
6. ADEQUACY OF THE RESULT
see attachment Sensitisation QSAR 278-137-2 - Acid Red 279
