Endpoint summary
Administrative data
Description of key information
Read across to analogue substance (Solvent Red 19E): In vivo skin irritation/corrosion test (EU B.4, GLP compliant) - positive result
Read across to analogue substance (Solvent Red 19E): In vivo eye irritation/corrosion test (EU B.5, GLP compliant) - negative result
Key value for chemical safety assessment
Skin irritation / corrosion
Link to relevant study records
- Endpoint:
- skin irritation: in vivo
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- REPORTING FORMAT FOR THE ANALOGUE APPROACH : Please see attached Read Across supporting document in Section 13 which includes the following:
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
3. ANALOGUE APPROACH JUSTIFICATION
4. DATA MATRIX - Reason / purpose for cross-reference:
- read-across source
- Irritation parameter:
- edema score
- Basis:
- mean
- Time point:
- 24/48/72 h
- Score:
- 0
- Remarks on result:
- other: Due to colouration of test substance the evaluation of erythema was not carried out.
- Irritant / corrosive response data:
- Based on results for an analogue substance, corrosion of the skin is not expected. However the analogue substance did cause dermal tissue changes (observed during histopathological examination). The target substance Solvent Red 19T is therefore also expected to be irritating to the skin.
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- Based on read across to an analogue substance, Solvent red 19T is predicted to be irritating to the skin and should be classified as skin irritant Cat 2.
- Executive summary:
A read across approach was used to determine skin irritant potential of Solvent Red 19 T ( 1-({2-methyl-4-[(2-methylphenyl)diazenyl]phenyl}diazenyl)-N-tridecylnaphthalen-2-amine). The results from an analogue substance with the same structure, but where the tridecyl group has been replaced with a 2 -ethyl hexyl group showed some dermal changes and therefore a classification of Skin Irritant Category 2 according to EU CLP criteria. Given the structural similarity, Solvent Red 19T should also be regarded as a skin irritant.

- Conclusions:
- Based on read across to an analogue substance, Solvent Red 19T is not irritating to eyes.
- Executive summary:
A read across approach was used to predict eye irritancy of Solvent Red 19T
( 1-({2-methyl-4-[(2-methylphenyl)diazenyl]phenyl}diazenyl)-N-tridecylnaphthalen-2-amine).
In-vivo data for an analogue subtance, with the
same structure, but where the tridecyl group has been replaced with a 2 -ethyl hexyl group concluded that the substance was not an eye irritant. Solvent Red 19T is therefore predicted to be non irritating to eyes.

Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to eye irritation.
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does require classification with respect to skin irritation as Category 2 (H315; Causes skin irritation).
