HYPOCHLOROUS ACID Chemical compatibility with O-rings, rubbers, & plastics

Hypochlorous acid (HOCl) is a weak acid formed when chlorine dissolves in water. It is a potent disinfectant used in various applications, including water treatment, sanitation, and wound care. Hypochlorous acid is effective against a wide range of pathogens, including bacteria, viruses, and fungi. It is commonly used in healthcare, food processing, and agriculture due to its broad-spectrum antimicrobial properties. Despite its effectiveness, hypochlorous acid is relatively safe for humans and the environment when used at appropriate concentrations. Proper handling and storage are essential to maintain its stability and efficacy. Diluted solutions are often used for disinfection and sanitization purposes.
