Physical description & handling notes

• Permethrin is a pale brown liquid. Relatively water insoluble. Used as an insecticide.
• Colorless to pale yellow solid or liquid; [Merck Index] Yellow-brown to brown viscous liquid or solid; [ICSC] Solid; mp = 34 deg C; [MSDSonline]
• Solid
• YELLOW-BROWN-TO-BROWN VISCOUS LIQUID OR CRYSTALS.
• Colorless crystals to a viscous liquid; Color, white to pale yellow
• Pure permethrin cis-isomer forms colorless crystals at room temperature but a mixture of cis and trans isomers normally occurs as a liquid, with its appearance depending on the ratio of isomers. Pure permethrin (40:60) is a colorless, viscous liquid, whereas the technical compound is a yellow to yellow-brown viscous liquid.
