Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Air and Water Reactions：

Water soluble.

Reactive Group：

Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters

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.

Ammonium lauryl sulfate Use and Manufacturing

Methods of Manufacturing

REACTION OF N-DODECYL ALCOHOL WITH CHLOROSULFONIC ACID FOLLOWED BY NEUTRALIZATION WITH AMMONIA

Uses

ammonium lauryl sulfate is a surfactant with emulsifying capabilities. given its detergent properties, at mild acidic pH levels it can be used as an anionic surfactant cleanser. It is considered one of the most irritating surfactants, causing dryness and skin redness. Today, it is either combined with anti-irritant ingredients to reduce sensitivity or replaced with a less irritating but similar surfactant, such as ammonium laureth sulfate.
