Summary
485/5000 1. Introduction: Rheological agents. Rheology (Definition, functional properties; Types of rheological behavior; Rheology of emulsions). 2. Hydrocolloids I (General; Starch, Gelatin, Xanthan Gum, Alginates, Carboxyl methyl cellulose, Carrageenan. Structure and applications). 3. Hydrocolloids II (Polymers, Structure and applications, Surfactant-Polymer Interaction). 4. Other rheological agents (Salt-Surfactant Interaction, Aluminosilicates, Organogels)
Educational goals
This course aims to introduce the student to the field of rheological agents and to make him acquire the general concepts which will allow him to modulate the viscosity of the formulated products. At the end of the course, the student will be able to: -Name the main rheological agents and describe the phenomena related to their application. - Interpret the most important factors in the use of polysaccharides (starch, xanthan gum, alginates, carrageenan), gelatin, synthetic polymers (acrylates, polyethylene glycol) and aluminosilicates as rheological agents - Explain the influence of polymer-surfactant interactions and the effect of salinity in the viscosity of their aqueous solutions
