Acute Toxicity: dermal
Administrative data
- Endpoint:
- acute toxicity: dermal
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From February 12 to 26, 1981
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Although conducted under worst-case conditions (abraded skin, occlusive dressing), no mortality was observed during this study. A repeat study is unlikely to show worse effects; therefore, this study was considered sufficiently robust to cover this endpoint.

- Executive summary:
In an acute dermal toxicity study (limit test) performed similarly to the OECD guideline No. 402 and in compliance with GLP, the abraded skin of albino rabbits (3/sex) was occlusively exposed to undiluted test material for 24 h at dose of 2000 mg/kg bw. Animals were observed for mortality, clinical signs and body weight changes daily for 14 days and then necropsied for macroscopic observations.
No mortality or clinical signs were observed. No abnormalities were noted at necropsy.
Dermal LD50 Combined > 2000 mg/kg bw
Under the test conditions, the test material is not classified according to the annex VI of the Regulation EC No. 1272/2008 (CLP).
This study is considered as acceptable and satisfies the requirement for acute dermal toxicity endpoint.
