Anionic surfactants are compounds that have negatively charged hydrophilic groups and break down surface tension due to their amphiphilic nature. They form soaps when reacted with metal hydroxides or alkalis.
Anionic Surfactants are very effective at lowering surface tension and reducing interfacial tension between molecules. Their negatively charged head groups interact electrostatically with the positively charged region of substances, making them excellent cleansing agents. Anionic surfactants generally have good solubilizing power, wetting ability, and foaming properties. They also boost miscibility and help disperse or solubilize hydrophobic compounds into water-based solutions.
