In this briefly reported study the toxicity of a polythene composition containing antimony trioxide (polythene + 0.2% “Akroflex” C/ antimony trioxide/“Chlorowax”) was tested.
(2) doses which varied between 600 - 1000 mg/kg/day were fed to 6 guinea pigs for 5d/wk for a total of 10 treatments.

Applicant's summary and conclusion

Conclusions:
This study is regarded as invalid and will not be used for the risk assessment of diantimony trioxide, due to the fact that the extract was not analysed and the amount of diantimony trioxide not known, the number of animals included in the study was not stated and no control animals was used.
