A detergent is a cleaning agent that helps remove dirt, stains, and grease from surfaces and fabrics. It works by breaking down the bonds between dirt and the material, allowing them to be washed away with water. Detergents are commonly used in laundry, dishwashing, and household cleaning products. Detergents can be found in various forms, including powders, liquids, and pods. They often contain surfactants, which are compounds that lower the surface tension of water, making it easier for the liquid to spread and penetrate surfaces. Common types of detergents include laundry detergents, dishwashing detergents, and all-purpose cleaners.
