A bleaching agent is a chemical substance used to lighten or remove color from materials. Commonly found in household products, these agents work by breaking down colored compounds, making them less visible. They are often used in laundry detergents, hair products, and cleaning supplies to achieve a brighter appearance. There are various types of bleaching agents, including hydrogen peroxide, chlorine bleach, and sodium hypochlorite. Each has specific applications and effectiveness depending on the material being treated. While effective, it's important to use these agents carefully, as they can cause damage to fabrics or surfaces if not used properly.
