Acute Toxicity: dermal
Administrative data
- Endpoint:
- acute toxicity: dermal
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- No data
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- A 1968 non-GLP study report without guidelines specified. However, the report contains the essential elements for an acute dermal toxicity study and there were sufficient data reported to come to a conclusion. The level of information reported for systemic toxicity parameters was minimal.

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: expert judgment
- Conclusions:
- The acute dermal LD50 for rabbits of either sex was > 3160 mg/kg. Skin reactions generally consisted of moderate erythema at 24 hours which diminished and completely subsided at all levels by Day 6, and slight desquamation in two to four animals which disappeared by Day 12.
- Executive summary:
In an acute dermal toxicity study, rabbits of either sex (New Zealand White) were given a single occluded dermal dose of MRD 68-28 in corn oil to the clipped abraded abdominal skin at nominal dosages of 50, 200, 754 or 3160 mg/kg. There were no deaths or no evidence of systemic toxicity observed during the subsequent 14-day observation period. Skin reactions generally consisted of moderate erythema at 24 hours which diminished and completely subsided at all levels by Day 6, and slight desquamation in two to four animals which disappeared by Day 12. Based on these results, the LD50 of MRD 68-28 was greater than 3160 mg/kg.
The toxicity study is considered acceptable for classification, and essentially satisfies the guideline requirements for rabbit acute dermal toxicity studies. The level of information reported for systemic toxicity parameters was minimal.
