Detergent is a cleaning agent that helps remove dirt, stains, and grease from various surfaces, including fabrics and dishes. It works by breaking down the bonds between dirt and the material, allowing them to be washed away easily. Detergents can come in liquid, powder, or tablet forms and are commonly used in laundry and dishwashing. Most detergents contain surfactants, which are compounds that lower the surface tension of water, making it easier for the liquid to spread and penetrate stains. Some detergents also include enzymes, which help break down specific types of stains, such as proteins or fats, enhancing their cleaning effectiveness.
