Abstract: The paper presents the results of an in vitro assessment of the photoprotective properties of compositions containing extracts of lichens Hypogymnia physodes, Evernia prunastri, Ramalina pollinaria and Cladonia arbuscula, 95% ethanol and castor oil in an amount of 15% of the volume. An increase in SPF, a decrease in ?crit and UV-A / UV-B due to the introduction of 15% castor oil are shown.
Key words: Lichen extracts, castor oil; compositions, sun protection factor (SPF); critical wavelength (?crit); alcohol solutions of extracts; absorption spectra; UV-A / UV-B ratio.
