Description
Sodium dodecyl sulfate (SDS), chemical formula C₁₂H₂₅OSO₃Na, is an anionic surfactant with excellent emulsifying, detergency, and foaming abilities. It is widely used in household chemicals, biochemistry, pharmaceuticals, and industrial cleaning.
Properties
Strong surface activity: It significantly reduces the surface tension of liquids and stabilizes emulsions and foams.
Strong detergency: It effectively cleans grease and proteins and is commonly found in detergents and shampoos.
Dentalizing effect: It is used for protein denaturation in biochemistry (e.g., SDS-PAGE electrophoresis).
Water solubility: It is readily soluble in water and forms micelles (critical micelle concentration (CMC) ≈ 8 mM).
Stability: It is resistant to hard water and remains active in acidic, alkaline, and high-temperature conditions.
Applications
1. Household chemicals and cleaning products
Shampoos and body washes: It serves as a foaming agent and detersive ingredient.
Toothpaste: A foaming agent that helps disperse plaque.
Laundry detergent and dishwashing liquid: A primary cleaning ingredient, particularly effective at removing grease stains.
2. Biochemistry and Molecular Biology
SDS-PAGE electrophoresis: Denatures proteins and makes them uniformly negatively charged, facilitating molecular weight analysis.
Cell lysis: Disrupts cell membranes to extract nucleic acids or proteins.
DNA/RNA purification: Removes impure proteins.
3. Pharmaceutical and Industrial
Drug formulations: Used as an emulsifier or solubilizer (e.g., ointments and emulsions).
Industrial cleaning: Used for metal degreasing, textile treatment, etc.
Emulsion polymerization: Used as an emulsifier to produce polymers such as acrylates and styrenes.
