Cleansing agents are substances used to remove dirt, impurities, and unwanted materials from surfaces or skin. They work by breaking down oils, grease, and other contaminants, making it easier to wash them away. Common examples include soaps, detergents, and shampoos, which are formulated to target specific types of dirt or stains. These agents often contain surfactants, which are compounds that lower the surface tension of water, allowing it to spread and penetrate more effectively. In addition to their cleaning properties, some cleansing agents may also have antibacterial or moisturizing effects, enhancing their overall effectiveness in maintaining hygiene and skin health.
