Aggregation Properties of Sodium Hyaluronate with Alkanediyl-α,ω-bis(dimethylalkylammonium Bromide) Surfactants in Aqueous Sodium Chloride Solution

Dimeric (Gemini) Surfactants: Effect of the Spacer Group on the Association Behavior in Aqueous Solution

“…The reported studies involved m-s-m dimeric surfactants and several water-soluble polymers (93)(94)(95)(96). The 12-s-12 surfactants were shown to interact weakly with hydroxypropylguar and strongly with hydrophobically modified hydroxypropylguar (93).…”

“…The study of the interaction between m-s-m surfactants and oppositely charged polyelectrolytes, poly(disodium maleatealt-alkylvinylether) (94) and hyaluronic acid (95,96), showed that, as for neutral polymers, dimeric surfactants interact more strongly than monomeric surfactants with the polymers.…”

Interactions between gemini surfactant alkanediyl-α,ω-bis(dodecyldimethylammonium bromide) and polyelectrolyte NaPAA

“…The transmittance has a minimum in the range of 190 < λ < 300 nm, which is the absorption band of NaPAA, and approaches 99.6% of the maximum magnitude as λ > 300 nm. The transmittance at λ = 450 nm (T 450 ), higher than the absorption band of NaPAA, were taken from the measured spectra in order to examine the surfactant effect [26]. Fig.…”

“…Only recently have there been a few such experimental studies, notably by Pisárčik et al [25][26][27]. They investigated the properties of cationic gemini surfactant with sodium hyaluronate (NaHA) using different techniques including viscosity and surface tension measurement, static and dynamic light scattering.…”

Salt effect on the interactions between gemini surfactant and oppositely charged polyelectrolyte in aqueous solution

“…The transmittance has a minimum at λ = 200 nm, which is the absorption band of NaPAA, and approaches 99.6% of the maximal magnitude as λ > 300 nm. The transmittance at λ = 450 nm (T 450 ), higher than the absorption band of NaPAA, was taken from the measured spectra in order to examine the surfactant concentration effect [26,28], as shown in Fig. 3B.…”
