Non-ionic surfactants are chemically potent molecular species that
are becoming increasingly important as an excipient component used
in the formulation and delivery of drugs and vaccines. These
chemicals do not have charge in their predominant working range of
pH, yet interact strongly with high energy structures such as
interfacial regions, phase boundaries and surfaces and can cause
dramatic changes in crucial properties of molecular mixtures
including solubility, dispersion uniformity, viscosity,
miscibility, phase and transport. Non-ionic surfactants are used
extensively in the chemical industry in such areas as detergents,
health and personal care, coatings and polymers. Furthermore,
non-ionic surfactants, or surface active wetting agents, reduce the
surface tension of water, allowing the water molecules to spread
out. When applied to water-repellent soils in high concentrations,
surfactants can improve the ability of the water to penetrate the
soil surface and thus increase the infiltration rate. This new book
gathers the latest research from around the globe in this field.
