Other Products

Sodium dodecyl sulfate has excellent emulsifying, foaming, water solubility, biodegradability, alkali resistance, hard water resistance, stability in aqueous solutions over a wide pH range, ease of synthesis, and low cost. It has been widely used in cosmetics, detergents, textiles, papermaking, lubrication, pharmaceuticals, building materials, chemicals, oil extraction, and other industries. It is also applied in basic research areas such as the properties of cationic-anionic surfactant mixed systems, micellar catalysis, and molecular organized assemblies.

Stability and Storage Conditions

Sodium dodecyl sulfate is a relatively stable surfactant, but containers should be kept sealed to avoid moisture and impurity intrusion, avoid direct sunlight, and should be stored in a cool, dry place to prevent the formation of harmful substances. Avoid contact with strong acids, strong bases, and incompatible materials.
