Acute Toxicity: dermal
Administrative data
- Endpoint:
- acute toxicity: dermal
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- GLP - Guideline study. According to the ECHA guidance document "Practical guide 6: How to report read-across and categories (March 2010)", the reliability was changed from RL1 to RL2 to reflect the fact that this study was conducted on a read-across substance.

Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: no mortality
- Mortality:
- No mortality occurred.
- Clinical signs:
- No systemic signs were observed in the animals during the entire observation period.
Skin observations: males/females: scales (back) (10/10); general erythema (back) (3/10); males: erythema focal (back) (3/5). All animals had recovered from the local signs after 7 observation days. - Body weight:
- Mean body weight (g): days 1, 8, 15
- males: 236.2, 265.2, 294.8
- females: 207.3, 214.0, 217.8 - Gross pathology:
- No abnormalities detected.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the results of the acute dermal toxicity study in rats (limit test), the dermal LD50 is > 2000 mg/kg bw and, thus, classification for acute dermal toxicity is not warranted.
