Structural Formula: Pyrethroid insecticide composed of a fluorinated phenoxybenzyl group and a cyano group
Inhalation: Take person to fresh air, keep at rest in a position comfortable for breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin immediately with soap and water, continue rinsing for at least 15 minutes, get medical advice if irritation develops
Eye Contact: Rinse carefully with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek attention if discomfort continues
Ingestion: Rinse mouth with water, do not induce vomiting, consult a physician or poison control center immediately
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray
Unsuitable Extinguishing Media: Do not use direct water jet
Fire Hazards: Combustible liquid, can produce toxic fumes including hydrogen chloride and oxides of carbon and nitrogen
Special Protective Equipment: Wear self-contained breathing apparatus, full protective clothing during fire fighting
Advice for Firefighters: Move containers from fire area if safely possible, use water spray to cool unopened containers, control run-off water to prevent environmental contamination
Personal Precautions: Evacuate unnecessary personnel, wear protective gear including gloves, goggles, and respirator
Environmental Precautions: Prevent product from entering drains, waterways, or soil
Methods for Cleanup: Contain and absorb spill with inert material (sand, earth), collect in suitable container for disposal, clean contaminated surface with detergent and water
Decontamination: Wash area with plenty of soap and water after removal
Disposal: Handle contaminated material as hazardous waste
Handling Practices: Maintain adequate ventilation, avoid direct contact with skin and eyes, use grounded equipment to avoid static discharge
Storage Conditions: Store in cool, dry, well-ventilated area, keep container tightly closed, protect from sunlight and moisture
Incompatible Materials: Strong acids, bases, and oxidizing agents
Container Recommendations: Use original packaging or suitable resistant containers, keep out of reach of children
Special Considerations: Avoid contamination of food, beverages, and animal feed during storage and use
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protective Equipment: Chemical-resistant gloves, protective clothing, eye protection (goggles or face shield), respiratory protection in case of insufficient ventilation
Hygiene Measures: Wash hands before eating, drinking, or smoking, remove contaminated clothing and wash before reuse
Occupational Exposure Limits: No OSHA PEL or ACGIH TLV established for cyfluthrin; follow manufacturer and country-specific recommendations
Environmental Controls: Avoid release to the environment, install spill containment if possible
Appearance: Off-white to beige powder or colorless to pale yellow liquid (depends on formulation)
Odor: Slight aromatic or solvent-like odor
Melting Point: 60–80°C (technical material)
Boiling Point: Decomposes before boiling

Vapor Pressure: Very low (2.5 × 10-7 mm Hg at 20°C)
Density: 1.2–1.3 g/cm³
pH (10% solution): 4–7
Partition Coefficient: log Kow = 5.9–6.3
Chemical Stability: Stable at recommended storage conditions, sensitive to light and prolonged heat
Reactivity: No hazardous reactions under normal use and storage
Decomposition Products: Thermal breakdown leads to formation of irritating and toxic vapors, including hydrogen chloride, carbon oxides, and nitrogen oxides
Incompatible Materials: Avoid contact with strong oxidizers, acids, and bases

Routes of Exposure: Inhalation, ingestion, dermal, ocular
Acute Toxicity: LD50 Oral (rat): 869 mg/kg; LD50 Dermal (rat): 1800 mg/kg; LC50 Inhalation (rat, 4h): 0.1 mg/L
Skin/Eye Irritation: Causes mild skin and moderate eye irritation
Skin Sensitization: Sensitizing in humans and animals
Chronic Effects: Prolonged or repeated exposure can affect the nervous system, liver, and potentially the reproductive system
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or EPA
Other Effects: May cause paresthesia (skin tingling), headaches, or dizziness even at low exposures
Ecotoxicity: Highly toxic to aquatic organisms, especially fish and invertebrates (LC50 Fish: 0.00068 mg/L over 96h - rainbow trout)
Persistence/Degradability: Persistent in soil and water with half-life of up to 68 days, degrades slowly by photolysis and microbial action
Bioaccumulation: High potential due to elevated log Kow
Mobility in Soil: Low to moderate mobility, tends to bind strongly to sediment and organic matter
Other Effects: Highly toxic to bees; do not apply during flowering periods
Precautions: Prevent contamination of surface and ground water during use and disposal
