Course content
- The current state of legislation in the field of cosmetic materials and resources. Expected trends. - Anatomy and physiology of the skin. Morphological differences in human skin. The most important problems in the behavior of the skin and its substructures, skin ageing. - Lipids in the skin. Barrier function of lipids. The binding of water in the skin. - Fats and oils in cosmetics. Influence of chemical composition. Possible interactions with other components of cosmetic products. - Surfactants in cosmetics. Types, the possible interaction with the skin and other ingredients. Perspective types of surfactants. - Polymers as cosmetic ingredients. Types of polymers, properties, interaction with the skin and surfactants, compatibility. - Anti-microbial agents and antioxidants as critical cosmetic ingredients. The principle of action versus the chemical composition. - The cosmetic product forms. Conventional forms (solutions, gels, ointments, emulsions). Effect of additives on the behavior of classical forms (mutual interaction of ingredients), the possibility of influencing their behavior. - Micro emulsion, nanoemulsions, Pickering´s emulsions, makroemulsion. Selection of emulsifiers. Preparation (cold emulsification, the PIT method). Liposomes. - Foams and aerosols. Formation and stability of foams. Foam stabilizers. Aerosols. - Functional cosmetics. Products for skin cleaning and conditioning. Skin care products. Ingredients that affect the skin condition (skin feel). - Hair Care. Special shampoos. Hair dye. Possible health risks. - Decorative cosmetics. Pigments organic, polymers and inorganic types, special additives. The problems of preparing different types of decorative cosmetics. - The assessment of cosmetic products. Performance evaluation, safety assessment. Instrumental methods.
