The part that is concerning is that Benzoyl Peroxide decomposes at a very high temperature (>100C), but the compound does produce free radicals that may be reacting with something else to produce Benzene. Saying that improper storage is causing this, is not sufficient. If tomorrow, the coloring agent and the sweetener in Coke Zero, when kept out in the summer, react with each other to produce Fentanyl, we shouldn't focus on the fact that drink was left out. We should focus on the fact that two ingredients could potentially react and form chemicals that can cause harm.
