- Conclusions:

(batch No. T710/712) was higher than 2000 mg/kg in rats. - Executive summary:
The objective of this study was to evaluate the toxicity of the test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate (batch No. T710/712), following a single dermal application to rats according to OECD (No. 402, 24th February 1987) and Commission Regulation (EC) (No. 440/2008, Part B.3, 30 May 2008) guidelines .
The study was conducted in compliance with the principles of Good Laboratory Practice Regulations.
Methods
The test item, Reaction mass of sodium sulfate, sodium amino-12-dodecanoate, was applied undiluted for 24 hours to the skin of five male and five female Sprague‑Dawley rats at the dose‑level of 2000 mg/kg, then the test site was covered by a semi‑occlusive dressing.
Each animal was observed at least once a day for mortality and clinical signs for a period of up to 14 days following the single administration. Body weight was recorded on day 1 and then on days 8 and 15.
On completion of the observation period, the animals were sacrificed then subjected to a macroscopic post-mortem examination.
Results
No deaths were observed during the study. Exophthalmos, then corneal opacity, was observed on the left eye of one animal only from day 3 and day 12, respectively, to the end of the observation period.
Erythema was noted on two males on days 2 and 3. Erythema was also noted on three, four and five females on days 2, 3 and 4, respectively. It persisted on these females until day 10 (one female), day 14 (one female) and the end of the observation period (three other females).
A brown discoloration of the skin, was observed in 9/10 animals until day 3, and until day 8 in 1/10 animals. It masked the evaluation of local reactions in one of them until day 3. Scabs were observed from day 4 until the end of the observation period in one female only.
When compared to CIT historical control data, a lower body weight gain was noted between day 1 and day 8 in all males (from 25 to vs. 47 ± in control data base) and 1/5 females (11 g vs. 25 ± in control data base). The body weight gain of these animals returned to normal thereafter.
No apparent abnormalities were observed at necropsy in any animal.
Conclusion
Under the experimental conditions of this study, the dermal LD50of the test item Reaction mass of sodium sulfate, sodium amino-12-dodecanoate and sodium dodecanoedioate (batch No. T710/712) was higher than 2000 mg/kg in rats.
