Influence of the Polymer–Micelle Interaction on Micelle‐Substrate Binding

Journal of Pharmaceutical Sciences, 2010
In an attempt to investigate how a nonionic polymer, hydroxypropyl methylcellulose (HPMC), interacts with a cationic surfactant, hexadecyltrimethylammonium bromide (CTAB), a dialysis method was employed for directly measuring the HPMC-CTAB interaction.

A phosphate-induced sub-micelle-micelle equilibrium in reconstituted casein micelle systems

Journal of Dairy Research, 1979
SUMMARYIn reconstituted casein systems, complete sub-micelles were previously observed only under extreme conditions of ionic strength, namely a NaCl concentration of 2 M or greater. However, studies with the analytical ultracentrifuge on phosphate-containing casein systems revealed that under certain conditions, a stable sub-micelle-micelle ...

Two-Step Micellization Model: The Case of Long-Chain Carboxylates in Water.

Langmuir, 2017
The micellization behavior of the long-chain carboxylates-sodium and potassium octanoate (NaC8 and KC8), sodium decanoate (NaC10), potassium decanoate (KC10), cesium decanoate (CsC10), choline decanoate (ChC10), and sodium dodecanoate (NaC12)-in aqueous ...

Micelle formation of sodium ursodeoxycholate and solubilization into the micelle

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2000
Abstract The micellization of sodium ursodeoxycholate (NaUDC) was studied at 298.2 K by aqueous solubility at different pH values. Using an association model of ursodeoxycholate anion without sodium counterion, the aggregation number ( n ) of the ursodeoxycholate micelle was evaluated and found to increase with the total concentration, indicating

Nonionic Surfactant Micelles and Mixed Micelles with Phospholipids

1979
The solution properties of nonionic surfactants of the polyoxyethylene variety and their interactions with various phospholipids are reviewed. Studies on polydisperse surfactants of the octylphenylpolyoxyethylene (OPE) class such as Triton X-100 as well as on homogeneous, monodisperse surfactants such as octylphenylnonaoxyethylene glycol (OPE-9) and n ...

Application of Conductance Study to Analyze Micellization Behavior of Cationic Gemini Surfactants in Water and Water–Ethanol Solvent Mixed Media

, 2016
The paper presents the analysis of micellization behavior of cationic gemini surfactants with similar structures with varying atom number in spacer: heptylene-1,7-bis(dimethyloctylammonium) bromide (8–7–8) and octylene-1,8-bis(dimethyloctylammonium ...

Solubilization of hydrocarbons by surfactant micelles and mixed micelles

Journal of Colloid and Interface Science, 1989
Abstract Extensive and highly precise vapor pressure results have been obtained for solutions of cyclohexane and hexane in cationic, anionic, and nonionic surfactant micelles, and in mixed anionic-nonionic, cationic-nonionic, and anionic-cationic micelles.

Effect of counterions on the micellization and monolayer behaviour of cationic gemini surfactants.

Physical Chemistry, Chemical Physics - PCCP, 2017
The effect of various inorganic and organic counterions on the aggregation behavior of gemini surfactants was examined to investigate the dominant influence of the anions on their micellization and aggregation behavior.
