Sodium Tetradecyl Sulfate is an anionic fatty alcohol sulfate surfactant based on a saturated C14 tetradecyl chain. It is the sodium salt of tetradecyl sulfate and is characterized by a hydrophobic 14-carbon alkyl chain attached to a hydrophilic sulfate group.
Sodium Tetradecyl Sulfate is also known as Sodium Myristyl Sulfate, Tetradecyl Sodium Sulfate, and Sodium 1-Tetradecyl Sulfate. It belongs to the fatty alcohol sulfate family of surface-active ingredients.
The molecule contains a saturated C14 hydrocarbon chain and a sulfate functional group with sodium as the counter-ion. This amphiphilic structure gives the ingredient its characteristic anionic surfactant properties.
Sodium Tetradecyl Sulfate can be considered for selected cleansing, foaming, wetting and surface-active formulation systems. Its performance depends on concentration, formulation composition, processing conditions, pH, water quality and the properties of the supplied grade.
Sodium Tetradecyl Sulfate is the sodium salt of tetradecyl hydrogen sulfate. It belongs to the anionic fatty alcohol sulfate category.
The tetradecyl chain contains 14 carbon atoms and is saturated. The sulfate group provides the ionic hydrophilic portion of the molecule, while the long hydrocarbon chain provides hydrophobic character.
This combination allows Sodium Tetradecyl Sulfate to interact with aqueous and hydrophobic phases and makes it relevant to surface-active formulations.
