Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Results of examinations

Clinical signs:
no effects observed
Mortality:
no mortality observed
Haematological findings:
no effects observed
Clinical biochemistry findings:
no effects observed
Urinalysis findings:
no effects observed
Organ weight findings including organ / body weight ratios:
no effects observed
Gross pathological findings:
no effects observed
Details on results:
Clinical observations:
No deaths and no signs of toxicity were observed.
Only limited details provided in NONS summary
Laboratory findings:
No treatment-related changes in haematological parameters
were observed.

Slight (1-3%) increases in plasma sodium and chloride were
observed in males at all doses as were slight (20-30%)
decreases in triglycerides. These changes were not observed

in males which received 1000 mg/kg/day and were allowed to
recover for 2 weeks.

Effects in organs:
No treatment-related gross or microscopic findings were
observed.

Applicant's summary and conclusion

Conclusions:
Dosing Sprague-Dawley rats with dose levels of up to 1000 mg/day produced only equivocal haematology and clinical
chemistry effects in either sex not considered to be related to the test material.
Therefore is was concluded that the test material is not classified under the test conditions
Executive summary:

No adverse effects noted up to 1000 mg/kg/day
