Sulfates
The sulfates were the largest and most important class of synthetic surfactants but have now been overtaken by the sulphonates.

DEA lauryl sulfate is used in shampoos. SLS was main surfactant for shampoos. excellent for creams and pastes. ALS is used in shampoos.
sarcosinates are used in Toothpaste, liquid soaps, shampoos, conditioning, and foaming; shaving preparations; foam baths; facial cleansers.
The sodium isethionate is prepared from ethylene oxide and sodium sulfite. Some typical impurities are salt, soap; fatty acid; unreacted isethionate.
Ester carboxylates result from the reaction of a long-chain fatty alcohol (or ethoxylate) with a multifunctional carboxylic acid (esterification).
Carboxylates are those surfactants with the hydrophilic group being a carboxyl group. There are now commercially available modified carboxylates …
A simple classification of surfactants based on the nature of the hydrophilic group is commonly used. anionic, cationic, nonionic, and amphoteric.
Surface active agents (usually referred to as surfactants) consist of a non-polar hydrophobic portion, attached to a polar or ionic portion (hydrophilic).
