Anionic surfactant is a kind of product with the longest development history, the largest yield and the most variety among surfactants. According to the structure of hydrophilic groups, anionic surfactants are divided into sulfonate and sulfated ester salts, which are the main categories of anionic surfactants at present. The main functions of surfactants are to change the surface of the liquid, the liquid-liquid interface and the liquid-solid interface, among which the surface (boundary) of the liquid is the most important.
