Interactions between Cationic Starch and Anionic Surfactants

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...

Thesis book INTERACTIONS BETWEEN CATIONIC POLYELECTROLYTES AND ANIONIC SURFACTANTS

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 of β-lactoglobulin with Cationic Surfactants: Spectroscopy Study

The interactions of β-lactoglobulin AB in the presence of cationic surfactants such as Cetyltrimethylammonium bromide and Cetyltrimethylammonium p-Toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, UV-Vis spectrophotometry and fluorimetry. The conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...
