Synergism between non-ionic and cationic surfactants in a concentration range of mixed monolayers at an air–water interface

Abstract

The mole fractions of TX100 (<italic>X</italic>s1) and C₁₆PC (<italic>X</italic>s2) at the interface <italic>vs.</italic> the total surfactant concentrations in the pre-micellar region, <italic>C</italic>₁₂, at various bulk mole fractions (<italic>y</italic>₁): (●) 0.1093, (□) 0.1995, (▲) 0.2901, (+) 0.3777 (*) 0.5001 and (○) 0.5972.
