Most Interesting Chemical: Pyrethroid Pesticide, Liquid Toxic: Pyrethroid Pesticide, Liquid, Toxic is combustible because both the pyrethoid and the carrier solvent are combustible. It is toxic because the pyrethroid active ingredient is toxic (toxic by inhalation, ingestion, and skin absorption). Pyrethroids oxidize rapidly and become less toxic or non-toxic upon exposure to air. Some individuals are more sensitive to pyrethroid poisoning than others. (Source: CameoChemicals.NOAA.gov).
