Results and discussion

Effect levels
Sex:
male
Dose descriptor:
LD50
Effect level:
1 290 mg/kg bw
Based on:
test mat.
Remarks on result:
other: oral administration of potassium butyl xanthate to rats produced increased motor activity, cyanosis, irritability, increased respiration and convulsions with death occurring 1 to 2 hours after administration.
Mortality:
All death occurring 1 to 2 hours after administration.
Clinical signs:
Oral administration of potassium butyl xanthate to rats produced increased motor activity, cyanosis, irritability, increased respiration
and convulsions with death occurring 1 to 2 hours after administration.
Body weight:
Weight gain amongst survivors was within normal limits.
Gross pathology:
Autopsy showed perivascular and pericellular oedema, multiple haemorrhages in the lungs, perivascular subarachnoid haemorrhages and acute
swelling of the cells of the cortex, subcortical ganglia and the brain stem. Fatty dystrophy of the liver and protein dystrophy of the twisted canaliculi of the
kidneys were observed.
Other findings:
The findings of these studies indicate that potassium isobutyl xanthate produces adverse effects on the central nervous system, liver and kidneys.

Applicant's summary and conclusion

Interpretation of results:
sligthly toxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The LD50 value of1290 mg/kg was determined in a reliable study. This show that Potassium Isobutyl Xanthate is of a Slightly order of acute oral toxicity .
Based on the data provided in this review, Potassium Isobutyl Xanthate shall be classified for acute oral toxicity.
