This episode explores the properties and potential applications of hypochlorous acid, a naturally occurring and surprisingly effective disinfectant. Against the backdrop of increasing awareness of various pathogens, the discussion centers on this compound's remarkable effectiveness—at least 100 times more potent than bleach—and its remarkable safety profile, even allowing for eye application. More significantly, the interview delves into the reasons behind its limited widespread use, primarily its instability and challenges in manufacturing and bottling. For instance, the guest explains how exposure to light, air, and pH changes can render the compound ineffective or even dangerous. As the discussion pivots to consumer products, the interview cautions against formulations containing unnecessary additives that compromise stability, recommending pure hypochlorous acid products for optimal effectiveness. In contrast to its potential for widespread use, the episode highlights that its effectiveness in air-based disinfection remains questionable. Ultimately, this episode reveals the fascinating duality of hypochlorous acid: a powerful yet gentle disinfectant with promising applications, but hampered by manufacturing and marketing challenges.
