Hydrogen peroxide is a chemical compound commonly used as a disinfectant due to its ability to kill bacteria, viruses, and fungi. It is a pale blue liquid that is highly reactive and decomposes rapidly in the presence of light. Hydrogen peroxide is often used as a cleaning agent in hospitals, households, and industrial settings, as well as in the food and beverage industry. It is also used as a bleaching agent for hair and teeth, and in the production of various chemicals and pharmaceuticals. However, it should be handled with care as it can cause skin irritation, respiratory problems, and eye damage if not used properly.
