Correlating the Structure and Rheology of Lamellar Liquid Crystalline Phases in Emulsions

This paper describes the correlation between the structure of liquid crystalline phases in emulsions and their rheological characteristics. An oleosome/lipophilic liquid crystalline-forming system and hydrosome/hydrophilic liquid crystalline-forming system were investigated. At the same high shear rate viscosity, the oleosome-system showed less thixotropy and rapid recovery when compared with the hydrosome-system.

Stimuli-responsive Polymer Systems: A Review of Thermo-associative Thickening

This article reviews recent trends in thermally initiated stimuli-responsive materials and provides some insight into the physicochemical mechanisms that underpin this behavior.

Comparatively Speaking: Newtonian vs. Non-newtonian Liquids

Industry expert Tony O'Lenick asks: What is the difference between newtonian and non-newtonian liquids? The answer to this question was provided by Peter Styne.

Colonial Launches HMW Betaine

Amphoteric Anionic Interactions

A study of interactions between anionic surfactants and amphoteric surfactants in solution demonstrates that betaines and anionic surfactants interact to have positive effects on viscosity, foam and the salt curve.
