Description:

Transfluthrin 95% TC is a high-purity synthetic pyrethroid insecticide characterized by its rapid action and strong vapor activity. It is primarily used in the formulation of household insect control products such as mosquito coils, liquid vaporizers, mats, aerosols, and other spatial repellents. The compound acts quickly on the nervous system of flying insects, especially mosquitoes, flies, and moths, leading to rapid knockdown and kill.

As a volatile pyrethroid, Transfluthrin offers efficient protection even at low doses and does not require direct contact with insects. It is widely used in both domestic and public health sectors and is particularly valued for indoor pest management in residential, commercial, and institutional environments.

Physical and Chemical Properties:

• Appearance: Clear to pale yellow liquid

• Odor: Slight aromatic odor

• Boiling Point: 150–160°C (at 0.1 mmHg)

• Melting Point: Below 0°C

• Density: ~1.51 g/cm³ at 20°C

• Vapor Pressure: ~2.7 × 10⁻³ Pa at 25°C (high volatility)

• Solubility: Practically insoluble in water; soluble in most organic solvents (ethanol, acetone, xylene)

• Stability: Stable under normal storage conditions; degrades in strong sunlight or heat

Specification Parameters:

Mode of Action:

Transfluthrin is a fast-acting neurotoxin that targets the sodium channels of insect nerve cells. It causes paralysis and death by disrupting the normal function of the nervous system. Unlike contact insecticides, Transfluthrin works primarily through inhalation due to its high volatility, making it ideal for spatial repellent applications.

Applications:

Primary Uses:

• Domestic insect control (mosquitoes, flies, moths)

• Public health pest management programs

• Manufacturing of mosquito coils, vaporizer refills, aerosols, mats, and other air-based insecticides

Application Areas:

• Homes and residences

• Offices and commercial buildings

• Hospitals and hotels

• Warehouses and storage areas

Formulated Products:

• Liquid Vaporizer (0.88% to 1.6%)

• Mosquito Coils

• Electric Mats

• Aerosol Sprays

• Passive Diffusers

Toxicological Profile:

• Oral LD₅₀ (rat): >5000 mg/kg (low toxicity)

• Dermal LD₅₀ (rat): >2000 mg/kg

• Irritation: Slight skin and eye irritant

• Sensitization: Non-sensitizer

• Inhalation Toxicity: Moderate (requires ventilation precautions)

• Environmental Impact: Toxic to aquatic organisms and bees; avoid environmental contamination

Packaging and Storage:

• Standard Packaging: 25 kg or 200 kg HDPE drums or iron drums with inner lining

• Storage Conditions: Store in cool, dry, and well-ventilated areas; avoid exposure to heat and sunlight

• Shelf Life: At least 2 years in sealed original containers

Conclusion:

Transfluthrin 95% TC is a high-efficiency active ingredient essential for modern insect control formulations. Its fast knockdown, vapor action, and safety profile make it ideal for household and public health pest management, contributing significantly to mosquito-borne disease prevention and improved quality of life.
