CAS Number 32612-48-9 / 67762-19-0
Chem/IUPAC Name: Ammonium dodecyl sulfate
EINECS/ELINCS No: 270-438-8
COSING REF No: 74404
Ammonium Laureth Sulfate is primarily a surfactant widely used in the cosmetic industry. It helps water and oil to mix well, thus helping the dust, dirt, and greasiness present on the surface of the skin to be washed away. Also known as ethoxylated alcohol, Ammonium Laureth Sulfate is also a foam booster and enhances user experience. It is commonly added to products like shampoos and cleansers. In its raw form, it appears as a yellowish liquid that is viscous and has large molecules that do not penetrate the surface of the skin - making it a safe choice. The chemical formula of Ammonium Laureth Sulfate is C14H33NO5S.


Ammonium Laureth Sulfate is a useful ingredient in personal care products targeting the cleansing of hair and skin.
  • Haircare: In hair care, Ammonium Laureth Sulfate works as a surfactant - effectively cleansing the scalp and hair by removing dirt, oil, and product buildup. Its gentle yet efficient cleansing action helps to maintain scalp health while leaving hair feeling clean, soft, and manageable
  • Skincare: Ammonium Laureth Sulfate is a foaming agent and an emulsifier, aiding in the removal of impurities and excess oil from the skin's surface. Its mild cleansing properties make it suitable for use in facial cleansers and body washes, leaving the skin feeling refreshed without causing excessive dryness or irritation


Ammonium laureth sulfate is typically synthesized through a process known as sulfation. First, ethylene oxide is reacted with ammonia to produce ammonium ethoxylate. Then, this compound undergoes sulfation by treatment with sulfur trioxide or sulfuric acid, resulting in the formation of ammonium laureth sulfate.

Safety profile

Ammonium Laureth Sulfate is a safe ingredient and can be used up to the concentrations of 20-35%. Due to its large molecules, it does not penetrate the skin and is also non-comedogenic. However, excessive amounts of this surfactant can be drying for the surface of the skin leading to sensitivity and irritation. It is necessary to follow the recommended guidelines for use and perform a patch test prior.
