Abstract
The surface activity and formation of liquid crystals by didecyl-dimethyl ammonium bromide (DDAB) in the presence of ethanol was studied. It was found that the critical micelle concentration and the area per molecule increased at an ethanol concentration above 2 M, in which a significant change in solvent properties occurs. DDAB formed lamellar liquid crystals which were destroyed by the added ethanol at a concentration similar to that which prevented the formation of micelles.
