Formation of colloidal components starting from a liquid-liquid phase separation.

Coacervation consists in the formation of drops containing oil. This process is obtained when a homogeneous solution containing charged molecules undergoes a liquid-liquid phase separation which in most cases results from the association of opposite charge molecules.

The advantages:

  • cost-effectiveness of the technique, materials, and polymers used
  • increase of the solidity and strength of the capsules

Features:

  • microcapsules with a size ranging from 1-100 um, payload up to 70-80%
