Physical description & handling notes

• Viscous liquid; [Merck Index]
• Viscous liquid
• Practically insoluble in water
• Soluble in alcohol, petroleum ether, kerosene, carbon tetrachloride, ethylene dichloride, nitromethane
• Oxidizes rapidly and becomes inactive in presence of air.
• Pyrethrums are highly unstable in the presence of light, moisture, and air. Whole flowers decompose more slowly than ground flowers or dust. Stored powders lose about 20% of their potency in one year. The potency of the pyrethrums can best be preserved in sealed, lightproof containers kept at lower temperatures. /Pyrethrum/

GHS Hazard Classification

Reported hazard statements	H302, H400, H410

Documented Uses

• Insecticidal component of pyrethrum flowers; Used as insecticide; [Merck Index]
• Pyrethrins are botanical insecticides ... used in these four general ways: (i) pre-harvest and postharvest uses on many agricultural crops; (ii) direct and indirect treatments of livestock animals and premises; (iii) treatments of commercial and industrial facilities and storage areas where raw and processed food/feed commodities are stored or processed; and (iv) wide area mosquito abatement use in areas which include aquatic areas. /Pyrethrins/
• Because of their safety, pyrethrum extracts are used extensively in stock sprays, aerosols, industrial sanitation sprays, and to protect stored food in warehouses. /Pyrethrins/
• For more Uses (Complete) data for CINERIN I (6 total), please visit the HSDB record page.
• Breathing in contaminated air; drinking contaminated water or eating contaminated foods; skin and eye exposure (L857).
• Pyrethrum extract contains six closely related insecticidal esters ... The six individual esters are not available commercially and are more economically produced as botanicals than by chemical manufacture.
