The Classification Of Surfactant
The classifications can be done in many ways, and according to its source, it can be divided into synthetic surface active agent, natural surface active agent and biological surface active agent.
Surfactant can be classified into anionic, cationic, amphoteric and nonionic types on the basis of the kinds of ions generated by hydrophilic group. The surfactant familiar to us has hydrocarbon alkyl group as its hydrophobic group, whose molecules may contain oxygen, nitrogen, sulfur, chlorine, bromine and iodine, named as hydrocarbon surfactant or ordinary surfactant. The one inclusive fluorine, silicon, phosphorus and boron is called special surfactant for these elements make surfactant more unique and excellent when brought in. Fluorosurfactant is one of the most important variety in special surfactant.
