Dissolution behaviour of sulphonamides into sodium

The surface energies of four sulfonamides have been assessed from contact angle data using the Lewis acid–base approach From these data the free energy of adhesion between the drugs and sodium dodecyl sulfate (SDS) head groups and tails has been calculated The most favored interaction was for adhesion to the SDS tails rather than the head groups The initial rotating disk dissolution

Emulsions: making oil and water mix

The HLB system which works primarily for non-ionic emulsifiers has been around since 1954 In the 1970s the hydrophilic-lipophilic difference (HLD) system was introduced The HLD system works for ionic as well as non-ionic surfactants and it is better able to take into account detailed characteristics of a particular emulsion such as salinity oil type surfactant concentration and
