Definitions for "Anionic surfactant"
A surfactant molecule that can dissociate to yield a surfactant ion whose polar group is negatively charged.
One which has a negative charge and migrates toward the anode or positive pole while in solution.
A surfactant derived from an aliphatic hydrocarbon and usually a sodium salt, in which detergent and other properties depend in part on the negatively charged anion of the molecule; hence the name "anionic."
