Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: no mortality occurred during the study.
- Mortality:
- No unscheduled deaths occurred during the study.
- Clinical signs:
- other: Chromodacryorrhea was observed in 1/5 males on days 7 and 8. As this clinical sign was of isolated occurrence, this was considered as incidental.
- Body weight:
- other body weight observations
- Remarks:
- Body weight of animals was unaffected by the test item treatment when compared to historical control data (see table 1).
- Gross pathology:
- There were no findings considered to be related to the test item administration.
The few macroscopic findings noted at the end of the treatment period (deformation and strangling of the spleen in a single male at 2000 mg/kg) were considered to be fortuitous. - Other findings:
- Erythema and edema were noted on application site of all male and female animals from day 2 up to day 7 at the latest. These findings were associated with dryness of the skin at application site of all males and at application site of 4/5 females from day 4 up to day 15 at the latest. In addition, desquamation was noted in 2/5 females from day 4 to day 13 or 14. Scabs on application site were also observed in 1/5 males and 1/5 females between day 5 and day 7.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the experimental conditions of this study, the dermal LD50 of 1,10-decanediol diacrylate was higher than 2000 mg/kg in rats. Therefore, the test item is not classified according to the Annex I of the Regulation EC No. 1272/2008 (CLP).
- Executive summary:
In an acute dermal toxicity study performed according to OECD Guideline No.402 and in compliance with GLP the test item, 1,10-decanediol diacrylate, was applied in its original form to the skin of five female then five male Sprague-Dawley rats at the dose-level of 2000 mg/kg. The application site was covered by a semi-occlusive dressing for 24 hours.
Each animal was observed at least once a day for mortality and clinical signs for 15 days. From day 2, any local reactions at the treatment site were also noted. Body weight was recorded on day 1 and then on days 8 and 15. On completion of the observation period, the animals were sacrificed and then submitted for a macroscopic post-mortem examination.
No unscheduled deaths occurred during the study. No clinical signs indicative of systemic toxicity were observed in any animals. Erythema and edema were noted on application site of all male and female animals from day 2 up to day 7 at the latest. These findings were associated with dryness of the skin at application site of all males and at application site of 4/5 females from day 4 up to day 15 at the latest. In addition, desquamation was noted in 2/5 females from day 4 to day 13 or 14. Scabs on application site were also observed in 1/5 males and 1/5 females between day 5 and day 7.
Body weight of animals was unaffected by the test item treatment when compared to historical control data. The test item administration did not induce any macroscopic findings at necropsy.
Under the experimental conditions of this study, the dermal LD50 of 1,10-decanediol diacrylate was higher than 2000 mg/kg in rats. Therefore, 1,10-decanediol diacrylate is not classified according to the Annex I of the Regulation EC No. 1272/2008 (CLP).
