Sodium Lauryl Sulfate SLS CAS 151-21-3 Anionic Surfactant With Strong Cleaning Detergency Ability
Sodium dodecyl sulfate (SDS), also known as sodium lauryl sulfate and industrially as K12, is an anionic surfactant belonging to the sulfate ester salt family. This versatile compound appears as white or pale yellow powder with a characteristic odor and lubricating feel.
Sodium lauryl sulfate is readily soluble in water, forming transparent solutions, and is slightly soluble in alcohol while insoluble in chloroform and ether. The compound exhibits excellent emulsifying, foaming, water-soluble, biodegradable, alkali-resistant, and hard-water-resistant properties. It maintains stability in aqueous solutions across a wide pH range and demonstrates over 90% biodegradability.

Product Name: Sodium Lauryl Sulfate (SLS)
Other Names: Sodium Dodecyl Sulfate (SDS), SLS Needle
Type: Anionic Surfactant
CAS No.: 151-21-3
Sodium lauryl sulfate is produced by reacting chlorosulfonic acid or concentrated disaccharide with lauryl alcohol (n-dodecyl alcohol). The reaction yields mono-dodecyl sulfate, which is then converted to sodium salt using aqueous sodium carbonate solution. Product extraction employs combined extraction and demulsification techniques to prevent emulsification issues.
