Cosmetic technology

Polymers are used in a wide range of cosmetic formulations with various functions, the main ones being rheology control, formulation stabilization, and conditioning. It is therefore important to understand their behavior in these complex environments, particularly by studying polymer-surfactant interactions, since these two components 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) the principle of thickening formulas or gelation using polymers; (3) interactions with surfactants, presentation of the different types of surfactants and their physicochemical properties, in particular polymeric surfactants, (4) interactions with surfaces (skin, hair) as well as any type of solid surface, (5) the principle of stabilizing emulsions and suspensions using polymers.

The second part of this module focuses on silicones and their use in cosmetics:

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