In my thesis, I investigated the formation of peroxylactic acid and peroxydodecylbenzenesulfonic acid in formulations prepared from different proportions of hydrogen peroxide and lactic acid or dodecylbenzenesulfonic acid (DBSA). I studied solutions containing 40% and 60% hydrogen peroxide and the effects of adding sulfuric acid as a catalyst. I found that the formulations with lactic acid were more promising than those with DBSA in terms of the percentage of peroxyacid formed and their stability. To simulate the storage conditions of such formulations over a longer period of time, I also thermally loaded the solutions at 60 °C for three days. In these cases, I additionally stabilized the solutions with HEDP. The results show that in the formulation with an initial ratio of 20% lactic acid and 40% hydrogen peroxide, the highest proportion of peroxylactic acid is formed after addition of the catalyst, which is also relatively stable, so that it can be a starting point for further studies.
