Description générale

IGEPAL® CA-720 is a nonionic polyoxyethylene surfactant.It is used as an effective emulsifier for nonpolar solvents in solvent emulsion cleaners. It can also be used as a flushing solution in electrokinetically enhanced in-situ flushing to remove polycyclic aromatic hydrocarbons (PAHs) from low-permeability clay soils.

Application

IGEPAL® CA-720 has been used:
  • as a component in reverse transcription (RT) mix for the recovery of variable heavy-light pairs (VH/VL) from sorted cells
  • in critical commercial assays
  • a surfactant in electrokinetics (EK) for the removal of organic contaminants
  • as a component of a binary mixture of Igepal and toluene to determine its density (ρ) and dynamic viscosity (η) to study the nature of the molecular interactions present in surfactants and cosurfactant mixtures

Caractéristiques et avantages

  • Improves system stability and durability
  • Exhibit good wetting properties

We investigate the controlled release of lidocaine hydrochloride from the doped silica-based xerogels. In the xerogel preparation, tetraethoxysilane (TEOS), methyltriethoxysilane (MTES), and propyltriethoxysilane (PTES) are used as precursors, and a nonionic surfactant Igepal CO 720 is used as a dopant.
