Description

Prallethrine 95% TC is a high-purity, oil-based technical concentrate in liquid form, primarily used in the formulation of insecticides for public health and domestic pest control. It is a type I synthetic pyrethroid known for its excellent knockdown effect against flying insects such as mosquitoes and flies. The product is widely utilized in liquid vaporizer formulations and aerosol sprays due to its rapid action, low mammalian toxicity, and volatility.

Prallethrine acts by disrupting the normal function of the insect nervous system, leading to paralysis and death. Its high efficacy at low doses makes it an economically and environmentally viable option for pest management.

Specification Parameters

Mode of Action

Prallethrine targets the voltage-gated sodium channels in the insect's nervous system. By holding these channels open, it causes repetitive nerve firing, leading to hyperexcitation, paralysis, and eventual death. Its fast-acting nature provides immediate knockdown, especially effective in enclosed spaces against flying insects.

Applications

• Public Health:

  • Used in electric liquid vaporizers, mosquito mats, and aerosols

  • Effective against mosquito vectors of malaria, dengue, and chikungunya

• Household:

  • Key component in domestic insecticidal products such as sprays, foggers, and mosquito coils

• Formulation Base:

  • Ideal for liquid vaporizer base (LVB) formulations

  • Compatible with perfumes, solvents, and stabilizers for long-lasting efficacy
