Four Most Commonly Used Surfactants You Should Know

Surfactants are substances used to reduce the surface tension of target solutions. It has fixed hydrophilic and lipophilic groups and can be aligned on the solution surface. The molecular structure of surfactants is amphoteric, with a hydrophilic end group and a hydrophobic end group. The hydrophilic group is polar and usually consists of carboxylic acid, sulfonic acid, sulfuric acid, amino or amine groups, and its salt. In contrast, the hydrophobic group is often referred to as a non-polar hydrocarbon chain, such as a hydrocarbon chain with greater than 8 carbon atoms. Surfactants can be further categorized as ionic surfactants (cationic surfactants and anionic surfactants), non-ionic surfactants, amphoteric surfactants, and others.
