Anionic agents are a type of surfactant that carry a negative charge. They are commonly used in various cleaning products, such as detergents and shampoos, due to their ability to effectively remove dirt and grease. These agents work by breaking down the surface tension of water, allowing it to spread and penetrate surfaces more easily. In addition to cleaning applications, anionic agents are also found in personal care products and industrial formulations. Examples include sodium lauryl sulfate and linear alkylbenzene sulfonate, which help to create foam and enhance the cleaning power of products. Their negative charge allows them to interact with positively charged particles, improving their effectiveness.
