Abstract
The subject of this study is 2-phenylbenzimidazole-5-sulfonic acid (PBSA), which is one of 26 filters used for personal protection in the European Union. The aim of the study was to investigate the stability of 2- phenylbenzimidazole-5-sulfonic acid and its sodium salt under the influence of various agents. The study has shown that UV radiation, pH value, hydrogen peroxide are important factors limiting the stability of PBSA. The significance of the study is expanding the knowledge about the stability of PBSA.
