For this family of materials: Did not cause cancer in long-term animal studies which used routes of
exposure considered relevant to industrial handling. Positiveresults have been reported in other
studies using routes of exposure not relevant to industrial handling. Contains an additional
component(s) that is/are encapsulated in the product and are not expected to be released under
normal processing conditions or foreseeable emergency.
Teratogenicity
For this family of materials: Did not cause birth defects or any other fetal effects in laboratory animals.
Reproductive toxicity
Contains component(s) which did not interfere with reproduction in animal studies.
Mutagenicity
For this family of materials: In vitro genetic toxicity studies were negative. Animal genetic toxicity
studies were negative.
Aspiration Hazard
Based on physical properties, not likely to be an aspiration hazard.
