Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In this experiment Diisononyl 1,4-cyclohexanedicarboxylate (DINCD) was
examined for acute toxicity after a single dermal application to rats. One dose level
of 2000 mg/kg b.w. was employed (limit test).
Under the present test conditions, a single dermal administration of 2000 mg
Diisononyl 1,4-cyclohexanedicarboxylate (DINCD)/kg b.w. did not reveal any signs
of toxicity. No death was recorded within the test period (one dosing day and
14 days of recovery).
One of the 5 female animals appeared to be reduced in body weight gain at the
end of the study.
No skin reactions were observed at the application site.
No signs of abnormalities were noted at necropsy.
