Sulfates
A surfactant—sometimes referred to as a detergent—is a substance that, when dissolved in water, gives a product the ability to remove dirt from surfaces such as the human skin, textiles, and other solids. There are several different types of surfactants, ranging from harsh to mild, with sulfates belonging to the class that is the most harsh.
Common sulfates as found on hair product ingredient bottles include:
Alkylbenzene Sulfonate
Ammonium Laureth or Lauryl Sulfate
Ammonium or Sodium Xylenesulfonate
Dioctyl Sodium Sulfosuccinate
Ethyl PEG-15 Cocamine Sulfate
Sodium C14-16 Olefin Sulfonate
Sodium Cocoyl Sarcosinate
Sodium Laureth, Myreth, or Lauryl Sulfate
Sodium Lauryl Sulfoacetate
TEA-Dodecylbenzenesulfonate
Some milder surfactants—less drying and recommended in lieu of sulfates—include:
Cocamidopropyl Betaine
Coco Betaine
Cocoamphoacetate
Cocoamphodipropionate
Disodium Cocoamphodiacetate or Cocoamphodipropionate
Lauroamphoacetate
Sodium Cocoyl Isethionate
