摘要: Abstract The main goal of the presented study was to analyze adsorption properties mixed surfactant systems containing esterquats which are biologically active and show strong surface activity in single solutions. subjects investigations were following cationic surfactants: fatty acids N , -dimethylaminoethylesters methobromides (DMM- n ), -dimethylaminopropylesters (DMPM- 1-dimethylamino-2-propyl (DMP 2 M- ) with different alkyl chain length. Sodium dodecylbenzenesulfonate (DBSNa) used as anionic surfactant. Two types equimolar considered: mixtures two well cationic + anionic i.e. an esterquat DBSNa. equilibrium dynamic tension data for all binary considered studied interpreted. Moreover, light scattering method determine micelles size. In case some synergism reduction critical micelle concentration evidenced. Kinetics dissociation found substantially surfactants components. results can be useful from standpoint biological applications.
