surfactants can be divided into four types according to the type of their hydrophilic groups: cationic, anionic, nonionic and zwitterionic. silicone surfactants can also be classified in this way. the hydrophobic group of silicone surfactants is composed of it is composed of alkylsiloxanes that are more hydrophobic than carbon chain types, has stronger surface activity than carbon chain types, and has lower surface tension in solutions of the same concentration.
