SEGREGATION OF MIXED MICELLES IN THE PRESENCE OF POLYMERS

The diffusion behaviour of an aqueous mixture of the sugar-based non-i onic surfactant dodecylmalono-bis-N-methylglucamide DBNMG and the anio nic surfactant of similar tail length, sodium dodecyl sulfate SDS, are examined in the presence of 5 mass% gelatin; the results clearly show that there are two types of mixed micelle present in the system arisi ng through competition between gelatin and the nonionic micelle for th e anionic surfactant.
