Alkyl sulfate

11.16.21

An anionic surfactant, usually a sodium salt, derived from fatty alcohol. Alkyl sulfates are high sudsing surfactants.

They have been an ingredient in built, all purpose granular detergents for many years; today they are more often found in cosmetic products, such as shampoos. Because they are sensitive to water hardness, they perform best in all purpose detergents that are fully built to inactivate the hardness.
