Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Conclusions:
The acute dermal toxicity of H 48 bleach was >2000 mg/kg bw. in the combined sex.
According to Directive 67/548/EEC and CLP GHS, H 48 bleach requires no classification, as the acute oral LD50 was >2000 mg/kg of body weight.
Executive summary:

The acute dermal toxicity of H 48 bleach was investigated in groups of 5 male and female New Zealand White rabbits after a single dermal administration of 2000 mg/kg bw.
