Skin irritation / corrosion
Administrative data
- Endpoint:
- skin irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- acceptable restrictions, mostly due to reduced reporting in times before GLP

Materials and methods
- Principles of method if other than guideline:
- Skin irritation was tested using an internal standard method (BASF test). White Vienna rabbits were used. Usually, animals were treated for 1, 5 and 15 minutes and for 20 hours using occlusive conditions. An application site of 2.5 X 2.5 cm was covered with the liquid or powdered and moistened test substance. Exposure of 1, 5 and 15 minutes was not done in this experiment
- GLP compliance:
- no
Test material
- Reference substance name:
- Manganese, 4-[(5-chloro-4-methyl-2-sulfophenyl)azo]-3-hydroxy-2-naphthalenecarboxylic acid complex
- EC Number:
- 226-102-7
- EC Name:
- Manganese, 4-[(5-chloro-4-methyl-2-sulfophenyl)azo]-3-hydroxy-2-naphthalenecarboxylic acid complex
- Cas Number:
- 5280-66-0
- Molecular formula:
- C18H11N2O6SClMn
- IUPAC Name:
- Manganese, 4-[(5-chloro-4-methyl-2-sulfophenyl)azo]-3-hydroxy-2-naphthalenecarboxylic acid complex
- Test material form:
- solid: nanoform
- Details on test material:
- - Physical state: solid
- Name of test material (as cited in study report): Litholechtscharlach 4300, C.I.Pigmentred 48:4, Monoazofarbstoff.
- Analytical purity: 100%
Test materials used in this dossier are all considered to fall under the definition of nano-materials according to the European Commission Recommendation 2011/696/EU as the synthesis and manufacturing of this pigment always yields particulate material with a fine particle size distribution.
