Inorganic Ingredients

The course aims to provide an overview of the main classes of inorganic ingredients in cosmetics according to INCI nomenclature, their use and the related issues of their employment in cosmetic formulations. A deep insight on the photochemistry principles and on the role of light and colours in cosmetics will be offered with a specific section devoted to the use of the different types of sunscreens and inorganic pigments. The chemical features and application in cosmetic formulations of silica derivatives will be presented with a look at the innovative aspects and formulations of inorganic ingredients.

By the end of the course the students will acquire knowledge about the chemistry and the application of the principal inorganic ingredients in cosmetic formulations gaining the ability for a critical evaluation. The students will understand the properties of inorganic pigments, their selection and dispersion and will acquire the bases of photophysical processes related to colours production and perception. A deep investigation of silica-based ingredients will be offered as well as their use in cosmetic formulations. Along with the frontal lectures, laboratory experiences will allow the students to practically develop selected topics of the course.
