Book Description
The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein a responsible industry mutually agreed to replace 'hard', non-biodegradable com ponents of household detergents by 'soft', biodegradable alternatives, without course to legislation. The only requirement at that time was for surfactants used in detergents to exhibit a 'primary biodegradability' in excess of 80%; this referring to the disap pearance or removal from solution of the intact surface active material as de tected by specified analytical techniques. This proved useful, as observed environmental impacts of surfactants, e.g. visible foam on rivers, are associated with the intact molecule. Test methods for 'primary biodegradability' were eventually enshrined in EU legislation for nonionic surfactants (Directive 821242/EEC, amended 73/404IEEC) and for anionic surfactants (Directive 8212431EEC, amended 73/405IEEC). No approved test methods and resultant legislation have been developed for cationic and amphoteric surfactants to date. The environmental classification of chemical substances, which of course includes surfactants, and associated risk assessment utilises a second criterion 'ready biodegradability'. This may be assessed by a number of methods which monitor oxygen uptake (BOD), carbon dioxide production or removal of dis solved organic carbon (DOC). Some surfactants which comply with the above Detergents Directive are borderline when it comes to 'ready biodegradability'.

Book Description
In response to intensifying interest on surfactant research brought on by recent innovation, Structure-Performance Relationships in Surfactants, Second Edition examines novel developments in our understanding of the properties and performance of surfactants at air-liquid, liquid-liquid, and solid-liquid interfaces, highlighting seven new chapters and carefully updated material to reflect current trends. This edition presents new material on the adsorption of vesicle-forming surfactants at the air-water interface, fluorinated surfactants having two hydrophobic chains, surface-active properties of telomer-type surfactants having several hydrocarbon chains, and the association behavior of amphiphilic dendritic polymers, among many other topics.

Book Description
Describes recent techniques applied to characterize surfactant systems, such as surfactant-stabilized colloids, micelles, microemulsions, emulsions and foams in both aqueous and nonaqueous fluids. The text probes adsorption and wetting phenomena at interfaces, including solid-liquid, liquid-vapour and liquid-liquid. It provides helpful examples and case studies illustrating how these techniques may be used in complementary ways.
