CH3CH211OSO3Na

CH3CH211OSO3Na, also known as sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), is an anionic surfactant with the chemical formula CH3(CH2)11OSO3Na. It is a white solid at room temperature, readily soluble in water. SDS is widely used in various applications due to its excellent detergent, emulsifying, and foaming properties.

In industrial settings, SDS serves as a surfactant in cleaning products, laundry detergents, and dish soaps. Its ability to lower the surface tension of water allows it to penetrate and lift dirt and grease effectively. It is also employed in industrial processes as a wetting agent, dispersant, and emulsifier.

In personal care products, SDS is a common ingredient in shampoos, body washes, and toothpastes. It contributes to the lathering action and helps to cleanse the skin and hair by removing oils and debris. However, its potent surfactant nature can lead to skin and eye irritation in some individuals, particularly with prolonged exposure or at high concentrations.

Beyond consumer products, SDS finds applications in scientific research. It is used in biochemistry and molecular biology for protein denaturation and electrophoresis, specifically in SDS-polyacrylamide gel electrophoresis (SDS-PAGE). This technique separates proteins based on their molecular weight. While effective, SDS's harshness requires careful handling and consideration of potential side effects in sensitive applications.
