Sun protection factors determination for cosmetic emulsions
 Slechanová, Veronika ; Jugl, Adam (referee) ; Smilek, Jiří (advisor)
The bachelor thesis deals with the anatomy and physiology of the skin, ultraviolet rays, sunscreens and current methods used to measure the value of sun protection factor. One of the goals of the thesis is to get the overview of the UV filters currently widely used in cosmetic products and giving them the required protection against the sun. The obtained knowledge was subsequently used for the determination of the sun protection factors in selected sunscreens by in vitro methods. The measurement provided satisfying results comparable with the values given on the label of the tested products. However, it is still necessary to optimize the methodology even more in order to obtain data with lower deviations and especially with much higher reproducibility.
