Endpoint:
acute toxicity: oral
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1983
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
similar to a guideline study, undertaken in a corporate laboratory at a time when reporting of minimal data was routine. Only basic data is provided in this report. Due to the corrosive nature of the substance, consideration of repeating this study is inappropriate and not in the spirit of minimizing animal testing, according to the REACH legislation.
