Surfactant, also known as surfactant, is a compound that can significantly reduce the surface tension or interfacial tension between two liquids, liquid-gas, or liquid-solid. The molecular structure of surfactants is amphiphilic: one end is a hydrophilic group and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine group and its salts , hydroxyl groups, amide groups, ether bonds, etc. can also be used as polar hydrophilic groups; while hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than 8 carbon atoms. Surfactants are divided into ionic surfactants (including cationic surfactants, anionic surfactants, amphoteric surfactants), nonionic surfactants, compound surfactants, other surfactants, etc.

Surfactant molecules have unique amphiphilicity: one end is a hydrophilic polar group, abbreviated as hydrophilic group, also known as oleophobic or oleophobic group, such as - OH- COOH、-SO3H、-NH2。 Due to the short length of these functional groups, they are sometimes referred to as hydrophilic heads. The other end is a non-polar group that is lipophilic, abbreviated as lipophilic group, also known as hydrophobic group or hydrophobic group, such as R - (alkyl), Ar - (aryl). Due to the short length of these functional groups, they are sometimes referred to as hydrophobic tails. Two types of molecular groups with completely opposite structures and properties are located at the two ends of the same molecule and connected by chemical bonds, forming an asymmetric and polar structure, thus endowing this special molecule with both hydrophilic and oleophilic properties, but not the overall hydrophilic or oleophilic characteristics. The unique structure of surfactants is commonly referred to as the "amphiphilic structure", and surfactant molecules are therefore often referred to as "amphiphilic molecules".
