carry a negative charge to effectively remove dirt and oils
Anionic surfactants, also known as anionic detergents, are a type of surface-active agent that carry a negative charge on their hydrophilic (water-attracting) end. This negative charge helps them effectively remove dirt and oils by breaking up and suspending these substances in water, making them common ingredients in shampoos, soaps, and other cleaning products.
