Anionic surfactants are mixtures of substances that have a negatively charged functional group. Like all surfactants, the anionic surfactants are composed of a polar and a non-polar part. An alkyl radical serves as the non-polar part. The polar, functional group is -COO-(carboxylate), -SO3-(sulfonate) or -SO42-(sulfate).
