Description
Polymers are used in a large number of cosmetic formulations with various functions, the main ones being rheology control, formulation stabilization and as a conditioning agent. It is therefore important to know their behavior in these complex environments, especially by studying polymer-surfactant interactions since these two constituents are often present together in these environments, as well as interactions with solid surfaces (suspensions, applications on hair or skin) or liquids (emulsions).
The course describes: (1) the different types of polymers used: water soluble, synthetic, natural and semi-natural, amphiphilic and structure-property relationships, (2) principle of thickening formulas or gelling using polymers, (3) interactions with surfactants, presentation of the different types of surfactants and their physico-chemical properties in particular polymeric surfactants, (4) interactions with surfaces (skin, hair) as well as any type of solid surface, (5) principle of stabilization of emulsions and suspensions using polymers.
A second part of this module is devoted to silicones and their use in cosmetics:
The chemistry of silicones, silicones for cosmetics: categories, their uses and sensory effects with examples of application.
