Cosmetic technology

Polymers are used in a large number of cosmetic formulations for a variety of functions, the main ones being rheology control, formulation stabilization and conditioning. It is therefore important to know how they behave in these complex environments, in particular by studying polymer-surfactant interactions, since these two constituents are often present together in these media, 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) and all types of solid surfaces, (5) principle of stabilizing emulsions and suspensions using polymers.

The second part of this module is devoted to silicones and their use in cosmetics:

Silicone chemistry, silicones for cosmetics: categories, uses and sensory effects, with application examples.
