Surfactants are divided into anionic surfactants, cationic surfactants, non ionic surfactants, and mixed surfactants.
The common anionic surfactants are Sodium dodecyl sulfate (SDS), Sodium dodecylbenzenesulfonate (SDBS), hexadecyl trimethyl Ammonium bromide (CTAB), etc.
Cationic surfactants commonly include: hexadecyl trimethyl Ammonium bromide (CTAB), Cetrimonium chloride (CTAC), etc.
Common non ionic surfactants include dodecanol polyoxyethylene ether (C12EO3), undecanol polyoxyethylene ether (C11EO5), etc.
