Inhomogeneous Distribution of Cationic Surfactants around Anionic Molecular Clusters

Interactions between Cationic Starch and Anionic Surfactants

Fabrication of vesicles from mixed cationic/anionic surfactants with additives

In this study, positively charged catanionic vesicles were fabricated from an ion pair amphiphile (IPA), hexadecyltrimethylammonium-dodecylsulfate (HTMA-DS), with the addition of a double-chained cationic surfactant, ditetradecyldimethylammonium bromide (DTDAB), and cholesterol by a mechanical dispersion process. The effects of the added cholesterol on physical stability of the catanionic vesic...

Charge screening between anionic and cationic surfactants in ionic liquids.

The aggregation and interfacial behavior of mixtures of anionic (sodium dodecylsulfate, SDS) and cationic (dodecylammonium bromide, DTAB) surfactants were investigated. A room-temperature ionic liquid (IL) was explored as a solvent for the SDS/DTAB system and compared to water. The critical micelle concentration (cmc) and composition in mixed micelles were determined for both solvents. Our expe...

Interactions between cationic starch and mixed anionic surfactants

The interactions of cationic starch (CS, degree of substitution=0.8)/mixed anionic surfactant/water systems were investigated. The surfactants investigated were sodium dodecyl sulphate (SDS), sodium octanoate (NaOct), sodium decanoate (NaDe), sodium dodecanoate (NaDod), sodium oleate (NaOl ) and sodium erucate (NaEr). The concentration of CS varied from 0.001 to 10 wt.%. The effect of mixing on...
