Anionic: Have one or more negatively (-) charged groupings; commonly used in laundry detergent
Cationic: Have one or more positively (+) charged groupings, typically poor detergents but well suited for use as germicides, fabric softeners and emulsifiers.
Amphoteric: Contain both anionic and cationic groupings; prefer neutral pH and found in products such as hair shampoo, skin cleaners and carpet shampoo.
• Ionic Surfactants make up >99% of the sufactant used around the world
Non-ionic: Have no ionic constituents or groupings; largest single group of SAA and have a correspondingly wide range of chemical characteristics. Ivey-sol® surfactant mictures are non-ionic and have the unique ability to selectively desorb contamination (LNAPL, DNAPL's, PAH, PCB, DCE, TCE, PCE), etc.
