Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- The back of each animal was shaved (approximately 10 % area of the total body surface) approximately 24 hours prior to treatment. The test item was applied as a single dose as supplied to the shaved skin and remained in contact with the skin for the 24-hour exposure period. Sterile gauze pads were placed on the skin of rats to cover the test item. These gauze pads were kept in contact with the skin by a patch with adhesive hypoallergenic plaster.The entire trunk of the animal was then wrapped with semi occlusive plastic wrap for 24 hours.
At the end of the exposure period, the area of skin treated with the test item was washed with water of body temperature. - Duration of exposure:
- The test item was applied as supplied as a single dermal 24-hour exposure followed by a 14 day observation period.
- Doses:
- 2000 mg/kg b.w.
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- not required
- Details on study design:
- A limit test was carried out at 2000 mg/kg body weight (bw) in both sexes (5 rats/sex). The test item was applied as supplied as a single dermal 24-hour exposure followed by a 14 day observation period. Clinical observations were performed on all animals at 1 and 5 hours after dosing and daily for 14 days thereafter. Body weight was measured prior to dosing on Day 0 and on Days 7 and 14. Gross macroscopic examination performed on all animals at the end of the 2-week observation period (Day 14).

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute dermal median lethal dose (LD50) of the test item Epoxidized Soybean Oil Acrylate was found to be greater than 2000 mg/kg body weight in male and female CRL:(WI) rats.
- Executive summary:
An acute dermal toxicity study was performed with test item Epoxidized Soybean Oil Acrylate in CRL:(WI) rats, in compliance with OECD Guideline No.: 402. A limit test was carried out at 2000 mg/kg body weight (bw) in both sexes (5 rats/sex). The test item was applied as supplied as a single dermal 24-hour exposure followed by a 14‑day observation period.
The acute dermal median lethal dose (LD50)of the test item Epoxidized Soybean Oil Acrylate was found to be greater than 2000 mg/kg body weight in male and female CRL:(WI) rats.
