PREPARATION AND RESEARCH OF COSMETIC EMULSIONS FROM SOLID TiO2 AND EMULSIONS PREPARED FROM DISPERSION OF TiO2

Original language description

The main aim of this work is preparation and characterization of cosmetic emulsions with different addition of TiO2 and different sun protection factor (SPF). TiO2 is the main component (main UV filter) of all emulsions in this study. TiO2 was used in dispersed form and in the form of a powder. A wide range of O/V emulsions were prepared. The preparation of the emulsion product allows the formation and combining of otherwise incompatible ingredients in an effective and commercially desirable cosmetic product. A key point in product development is the choice of suitable raw materials and the emulsion preparation method because materials and preparation method affect properties of the resulting emulsion such as stability, viscosity and others. The stability of the emulsion depends on various parameters such as particle size, crystal formation, activity of the components used to achieve the desired rheological properties of the product. These parameters depend on temperature so the rate of heating, the method and the rate of mixing of the phases and the cooling rate are very important. An analytical centrifuge was used to determine the stability of the emulsions and the results obtained by analytical separation were compared with gravity stability tests. Mechanical properties of prepared emulsions were tested by rotational rheometer. Nowadays there is an extensive list of active ingredients that can be used as additives for various cosmetic emulsions. The choice is limited by the laws of the state in which the final product is to be placed on market. In this study the combinations of UV filters (which are allowed in Czech Republic of course) were used to obtain final products with different values of SPF. The SPF values in this study were determined by an in vitro tests. This method evaluates the UV transmission through a thin layer of the sunscreen product. The whole experiment was performed on the defined roughness plates on which the product was torn. These plates m
