Applicant's summary and conclusion

Conclusions:

According to current valid guidance the test substance with the result of LD50 in acute oral test higher than 2000 mg/kg is considered as non-toxic after single oral application. Acid Brown 235 did not penetrate into the organism through the skin after single application.
The test substance is considered to be non-irritating to the eye and skin of rabbit.
The test substance elicited negative sensitising response in mice.
According to results of acute exposition of the test substance Acid Brown 235 can be expected, that the test substance did not penetrate through the skin and digestive tract after single administration.
The test substance has not systemic toxic effect after repeated oral administration.
Test substance did not influenced reproduction parameters of males and females. Development of pups was not influenced by the test substance administration.
Results recorded during the reproduction part of study with repeated oral administration showed that the test substance did not penetrate into the testes and through the placental barrier.
No data about metabolism and excretion of the test substance were found.
