Surfactants are the substances which show surface activity .Detergents possess surface activtiy as wll as detergency . Soaps are anionic class of detergents . It is the hydorphilic part of detergent momencule which possesses the tendecy to attract water moleculse wheras hydrophilic blances part orients away from waer . The hydrophilic-lipphilic balance (HLB) leads to affergation of anooic or non-ionic or cationci part of detergent to form icellse . Each molecule has the defintie concentration at defintie temperature at which it states to aggrater . It is due to teh presence of two moities in their molecules, surffactants stabilize emulision ( a water -oil system ) . Due to larger surface area, the mediacines are more effective in emulion form . Emulisons are ` w//o or o //w type`. A water soluble dye imparts its collour to ` o//w` emulsions.
which of the following forms a cationic miclels ?
