The laws of the foam stabilization by mixtures of surfactant of different nature: sodium dodecyl sulfate C 12 H 25 OSO 3 Na and cetyltrimethylammonium bromide C 16 H 33 N(CH 3 ) 3 Br with a nonionic polymer, polyvinyl alcohol were established. High stability of foams from mixtures of surfactant-polyvinyl alcohol compared with the individual components can be related to the formation of mixed structured layers of surface active associates of polyvinyl alcohol with surfactant contributing to thickening of foam films.
