Sodium dodecyl sulfate, interactions with

The presence of surfactants, besides altering the latex particle surface, can also interact with the water-soluble polymer. For instance, poly(ethylene oxide) homopolymer and block copolymers interact with sodium dodecyl sulfate surfactant [109], and hence alter the latex viscosity behaviour [110]. Other water-soluble polymers are also capable of interacting with specifle surfactants [111]. When pigmented latex dispersions are thickened with associative thickeners one must consider the interactions with some of the pigment stabilizers [112] and other additives, like coalescing aids [113]. [Pg.126]

Fluorescence probing has also been used by us to investigate the mechanism of vesicle to micelle transformation due to interaction of liposome with sodium dodecyl sulfate micelles. An increase in optical density and hydrodynamic diameter was observed at low SDS concentrations (Fig. 24). The increase was attributed to the incorporation of SDS monomers on liposome vesicles. The point where the hydrodynamic diameter and optical density reached a maximum was proposed to correspond to the saturation of bilayers of the first inflection point. Upon further increase in the SDS concentration... [Pg.160]

The effect of interaction of sodium dodecyl sulfate with the polymer, polyvinylpyrrolidone, on the foaming of aqueous solutions of the former has been investigated by Folmer and Kronberg (2000). Depending upon the surfactant and polymer concentrations, the foaming can either be decreased or increased. Foaming increases when surface and/or bulk viscosities are increased by the surfactant-polymer concentration it decreases when surfactant-polymer interaction in the bulk phase causes desorption of them from the air-aqueous solution interface. [Pg.297]

A number of surface functionalization chemistries were explored which yielded substantially improved affinity of albumin for a number of polymer substrates (18,20,21). Albumin binding was shown to increase as the degree of surface alkylation was increased ( ). Albumin bound rapidly (within 30 sec) in an apparent substrate specific manner (Fig. 7). While these results demonstrated that, given enough time, more albumin would bind to untreated surfaces, it was also found that the hydrophobic interaction at the alkyl site gave a more tenacious bond, resisting both fluid shear desorption (Fig. 8) and elution with sodium dodecyl sulfate and other protein denatur-ants (23,24). [Pg.388]

Surfactant concentration (varied after polymerization) greatly affects the viscosity of associating polymer systems. Iliopoulos et al. studied the interactions between sodium dodecyl sulfate (SDS) and hydrophobically modified polyfsodium acrylate) with 1 or 3 mole percent of octadecyl side groups [85]. A viscosity maximum occurred at a surfactant concentration close to or lower than the critical micelle concentration (CMC). Viscosity increases of up to 5 orders of magnitude were observed. Glass et al. observed similar behavior with hydrophobically modified HEC polymers. [100] The low-shear viscosity of hydrophobically modified HEC showed a maximum at the CMC of sodium oleate. HEUR thickeners showed the same type of behavior with both anionic (SDS) and nonionic surfactants. At the critical micelle concentration, the micelles can effectively cross-link the associating polymer if more than one hydrophobe from different polymer chains is incorporated into a micelle. Above the CMC, the number of micelles per polymer-bound hydrophobe increases, and the micelles can no longer effectively cross-link the polymer. As a result, viscosity diminishes. [Pg.660]

The hybrid or complex nonchemical interactions are the basis for the construction of new artificial systems composed of certain proteins, such as P-lacto-globulin or serum albumin, with sodium dodecyl sulfate (SDS) to be used in systems in which electrostatic stabilization of O/W emulsions is essential. [Pg.357]

Contact of surfactants with the skin and mucus membranes occurs either accidentally or as a consequence of normal use. Examples of this normal and everyday use are cleaning formulations, shampoos, foam baths, and toothpastes. Again this contact is seldom made with individual surfactants, in this case alcohol sulfates and alcohol ether sulfates, but through formulated products. It is known that surfactants present significant interactions, so that mixed systems are generally less aggressive than their individual components. However, the effect of pure surfactants merits attention, particularly sodium dodecyl sulfate, which is commonly used as a reference for many studies because of its high purity and availability. [Pg.289]

The Langmuir-Blodgett method has been used to prepare hybrid films of an anionic Ru(ll) cyanide polypyridyl complex with LDHs [170]. An LDH film was formed on mica owing to the interaction between LDHs particles and the Ru(ll) cyanide polypyridyl complex that was pre-dispersed on the surface of mica. Water-in-oU emulsions composed of octane, water and sodium dodecyl sulfate (SDS) have been used to synthesize Mg/Al LDHs with carbonate as the interlayer anion [171] by constant pH or variable pH methods. A floccule or fiber-like LDH material that possesses similar chemical composition and properties to that synthesized using a conventional variable pH method was obtained. The resulting LDH shows high surface area and a narrow distribution of mesopores. [Pg.112]
