Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2005 - from collection of data, only completed year noted.
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Considering the structural similarities of both molecules and the probability to act via a common mode of action, it is acceptable to utilise EC 209-711-2 as a read-across source. See attached document for full justification.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Conclusions:
- m-Aminophenol induced contact sensitisation in a murine Local Lymph Node Assay and was rated to have a strong sensitisation potential.
Classified as Category 1 for skin sensitisation potential according to EC 1272/2008. - Executive summary:
A Local Lymph Node Assay was conducted in female CBA/J mice to investigate the sensitisation potential of m-aminophenol. Concentrations up to 25% (the maximum soluble concentration) in dimethylformamide were tested in two successive experiments. A positive control group received 25% alpha-hexylcinnamaldehyde in dimethylformamide. No mortality, clinical signs or body weight changes could be attributed to compound administration. An increase in stimulation index was observed with increasing dose and the threshold positive value of 3 was exceeded at concentrations of 0.5% and higher.
m-Aminophenol induced contact sensitisation in a murine Local Lymph Node Assay and was rated to have a strong sensitisation potential.
Classified as Category 1 for skin sensitisation potential according to EC 1272/2008.
