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 ...

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.

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 ...

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

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.

On the Thermodynamics of Reverse Micelles: Effect of Water on Micellization

Colloid Journal, 2020
Water may be involved in reverse micelle formation either in the form of a hydration shell or as a solubilisate. Both cases have been analyzed within the framework of a theory based on the mass action law and the definition of the critical micelle concentration (CMC) via the constant of this law.

ChemInform Abstract: ON THE STRUCTURE OF MICELLES

Chemischer Informationsdienst, 1984
Les etudes cinetiques de l'oxydation des olefines micellaires par des ions permanganate, en solution aqueuse, a 25°C et pH 12, montrent qu'une olefine terminale est oxydee avec une rapidite superieure de 2 ordres que les olefines internes. Ce fait est interprete par le desordre et les enroulements rencontres dans la region de Stern riche en ...

Micelles and Reversed Micelles: A Historical Overview

1984
This is a review of the historical development of models for micelle formation in aqueous solution, lyotropic liquid crystals, reversed micelles and microemulsions. The current model of micelle formation was suggested about fifty years ago, while the quantitative development of thermodynamic and kinetic models is relatively recent.
