The course is addressed to create a know-how in Cosmetic Chemistry supplying the necessary elements to know the raw material’s classes and their functionality inside the cosmetic products.
Interfacial phenomena. Surfactants chemistry and classification. Physical properties of surfactants used in cosmetics. Theories of emulsification. Physical stability of emulsions. Emulsifiers. Colloids and macromolecular systems. Dispersed systems. Rheology, Polymers and rheological additives (hydrophilic, lipophilic and emulsifier).
Oils fats and waxes. Chemistry and cosmetic properties. Lanolin and its derivatives.
Humectants. Drying out. Hygroscopicity. Chemical classes. Cosmetic application. Sunscreens. Sun protection factor. Chemical and physical sunscreens. Vehicles. Photostability. Substantivity evaluation.
