Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, single dermal application of the test item to rats at a dose of 2000 mg/kg body weight was associated with no mortality and neither signs of toxicity nor signs of irritation.The dermal LD50 was determined to be > 2000 mg / kg body weight.
- Executive summary:
Under the conditions of the present study, a single dermal application of the substance to rats at a dose of 2000 mg/kg body weight was associated with no signs of toxicity or mortality. The median lethal dose of the test item after a single dermal administration to male and female rats, observed over a period of 14 days is:
LD50 > 2000 mg/kd bw; unclassified In conformity with the criteria given in Annex VI to Commission Directive 2001/59/EC the test item has no obligatory labelling requirement for toxicity. According to Annex I of Regulation (EC) 1272/2008 the test item has no obligatory labelling requirement for toxicity and is not classified. According to GHS (Globally Harmonized Classification System) the test item has no obligatory labelling requirement for toxicity and is not classified.
