Microemulsion (ME) Formulation

Is a clear, thermodynamically stable liquid system where oil and water phases are finely dispersed using surfactants and co-surfactants. Unlike traditional emulsions, ME droplets are typically <100 nm, making them transparent and highly efficient for agrochemical delivery.

Key Features of ME Formulations:

  • Transparent appearance due to ultra-small droplet size

  • Thermodynamic stability: No phase separation over time

  • Low viscosity: Easy to handle and mix

  • Enhanced bioavailability: Better penetration and distribution on plant surfaces

Advantages:

  • Requires lower doses of active ingredient for same efficacy

  • Environmentally friendly: Often water-based with minimal solvents

  • Ideal for home & garden, wood preservation, and low-dose applications

  • Compatible with sensitive actives that degrade in traditional EC or EW formats

Typical Components:

ComponentFunction
Active ingredientLiquid or dissolved pesticidal agent
Surfactants & co-surfactantsReduce interfacial tension and stabilize droplets
Water phaseContinuous phase for dispersion
Oil phaseMay contain active or solvent
Cosolvents (e.g. alcohols)Aid in phase inversion and droplet control
 

ME formulations are often developed using phase inversion techniques, where a water-in-oil system is gradually converted to oil-in-water under controlled shear and temperature.  Their optical clarity, low toxicity, and high performance make them a cutting-edge choice in modern agrochemical design.
