Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Diss Factsheets

Administrative data

Endpoint:
acute toxicity: dermal
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Secondary information from a study in rats, performed in 1973, taken from public TSCA8e submission file. Study was not performed according to GLP, but test parameters documented are sufficient to accept the data, which are well documented and scientifically acceptable.

Results and discussion

Effect levels
Dose descriptor:
LD50
Effect level:
> 2 150 mg/kg bw
Mortality:
No signs of systemic toxicity were observed. One of four annimals died during the experiment. The fatality was due to the severe eschar caused by this corrosive compound.

Applicant's summary and conclusion

Conclusions:
The dermal LD50 was determined to be greater than 2150 mg/kg bw after occulsive application to the skin of rabbits.
