Repeated dose toxicity: dermal
Administrative data
- Endpoint:
- short-term repeated dose toxicity: dermal
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 25.03.-13.08.1992
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- GLP - Guideline study, tested with the source substance tetramethylthiuram disulfide (CAS No. 137-26-8). In accordance 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. (For detailed information on the justification of read-across, please refer to the analogue justification document attached in IUCLID section 13).

Any other information on results incl. tables
Clinical signs:No treatment-related changes were observed.
Mortality: No deaths.
Local dermal irritation: Control group: no dermal signs. All treatment groups: slight or well-defined erythema with or without slight or well-defined oedema, with well-defined responses noted with greater frequency in the mid- and high-dose group. Reactions were observed initially in isolated incidences on Day 7 but over the following two weeks developed in the great majority of rabbits. These reactions were frequently accompanied by residual (brown) staining from the test substance and/or desquamation of the stratum corneum.
Bodyweight gain: Reduced bodyweight gain was observed in females dosed at 1000 mg/kg bw/day.
Food consumption: Reduction in mean food consumption was measured for females dosed at 1000 mg/kg bw/day throughout the study. These changes were statistically significant (p 0.05) in week 1 and 2.
Blood analysis: Haematology: No treatment-related changes. Clinical chemistry: Liver enzymes GOT, GPT, and cholesterol levels were increased in females dosed at 1000 mg/kg bw/day. Alkaline phosphatase activity was increased at 1000 mg/kg bw/day in both sexes.
Sacrifice and pathology: Organ weights: No dose-related effects.
Gross and histopathology: Gross pathology: no treatment-related effect.
Histopathology: Minimal generalised/focal acanthosis of epidermis at the treated skin sites of all male and female rabbits were considered treatment-related.Applicant's summary and conclusion
