Usage

Description

Ammonium lauryl sulfate is a light yellow, viscous liquid that may float or sink and is capable of mixing with water. It is a surfactant with emulsifying capabilities and is known for its detergent properties, making it useful in various applications across different industries.

Uses

Used in Cleaning Products:
Ammonium lauryl sulfate is used as an anionic surfactant cleanser for its detergent properties at mild acidic pH levels. However, it is considered one of the most irritating surfactants, causing dryness and skin redness. To mitigate this, it is often combined with anti-irritant ingredients or replaced with a less irritating but similar surfactant, such as ammonium laureth sulfate.
Used in Cosmetic Products:
In the cosmetic industry, ammonium lauryl sulfate is used as an anionic surfactant in the formulation of various products due to its emulsifying and cleansing properties.
Used in Building Ceramics:
Ammonium lauryl sulfate can be utilized in the preparation of porous building ceramics through the gelcasting process, contributing to the manufacturing of construction materials.
Used as a Corrosion Inhibitor:
In the field of material protection, ammonium lauryl sulfate serves as a corrosion inhibitor for carbon steel in acidic solutions, helping to prevent the degradation of metal surfaces.

Air & Water Reactions

Water soluble.

Reactivity Profile

Acidic inorganic salts, such as Ammonium lauryl sulfate, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid.

Health Hazard

Contact with liquid irritates eyes and may have drying effect on the skin. Prolonged contact will cause skin irritation.

Fire Hazard

Special Hazards of Combustion Products: Toxic oxides of nitrogen and sulfur may form in fires.

Purification Methods

Recrystallise it first from 90% EtOH and then twice from absolute EtOH, and finally dry it in a vacuum. [Beilstein 1 III 1786.]
