Combined processes emulsified solvent

To overcome the fact that a single solvent rarely completely extracts all the potentially available components from a herb, multi-solvent extracts have been developed. In this process, initial extraction of the herb using a non-polar solvent is followed by extraction using a more polar solvent. The two extracts are then concentrated to remove the solvents. Finally, they are combined using a suitable emulsifier system to hold the two incompatible components together without separating. This will render the extract water soluble (or at the least miscible) without settling-out in the final product. 

It is the simplest approach, where suitable monomer (precursor of CP/ ICP) has been polymerized (Figure 1.45) in the presence of dispersed filled inclusion (another CP metallic, dielectric, or magnetic NPs QCNs any suitable combination of them). Depending upon the nature of reaction medium (i.e., presence of solvent, dispersant, or emulsifier), the polymerization may proceed via bulk, solution, suspension, or emulsion route [14,375,502]. During the process, monomer(s) tends to adsorb over filler and polymerize over the same, thereby enwrapping it and causing its dispersion within the formed polymer matrix.
