Hardly soluble in water or other hydroxylic solvents, soluble in most of organic solvents. Thermally stable at room temperature. In water DT50 for ? :36, 17, 7; ? :117, 20, 6; ? : 30, 11, 3; ? : 25, 11, 5 (all in days, pH 4, 7, 9 respectively, 22 oC ) TOXICOLOGY: Cyfluthrin is considered moderately toxic to mammals. The oral dose of cyfluthrin that resulted in mortality to half of the test animals (LD50) ranged from 869 - 1271 mg/kg in rats, 291 - 609 mg/kg in mice, >1000 mg/kg in sheep, > 100 mg/kg in dogs and > 1000 mg/kg in rabbits. In inhalation toxicity tests with rats, the concentration of cyfluthrin in air that resulted in mortality to half of the test animals (LC50) was >1,089 ug/l in 1 hour tests, and ranged from 469 - 592 ug/l in 4 hour tests. Although cyfluthrin is an irritant to human skin, especially facial skin, it is not considered to have high dermal toxicity. The dermal LD50 in tests with rats was > 5,000 mg/kg, and was not found to be a skin irritant or sensitizer in guinea pigs and rabbits.FORMULATION AND SPECIFICATION: Items 95 Technical 5EC Appearance Yellow to Brown even liquid Brown yellow transparent liquid Assay, % 95.0 min 5.0min Moisture, % 0.3max 0.3max Acid (H2SO4), % 0.2max 0.2max PACKING: 200kg in iron drum, or on the client's requirement
