Sodium dodecyl sulfate CAS:151-21-3

Cleaning agent: SDS is a common ingredient in household cleaning products, such as dishwashing detergents and laundry detergents. It acts as a surfactant, reducing the surface tension of water and allowing it to more effectively remove dirt and grease from surfaces.

Industrial cleaning: SDS is used in industrial cleaning applications, especially in industries like food processing, where it helps remove oils, stains, and stubborn residues.

Personal care products: SDS is found in many personal care products, such as shampoos, body washes, and toothpaste. It acts as a foaming agent, helping to create a lather and improve the spreadability of the product.

Protein extraction and purification: SDS is widely used in protein extraction and purification techniques, particularly in electrophoresis. It denatures proteins and coats them with a negative charge, allowing them to separate based on size when subjected to an electric field.

DNA extraction: SDS is used in DNA extraction protocols to lyse cells and release DNA. It disrupts the cell membrane and denatures proteins, facilitating the release and subsequent isolation of DNA.

Molecular biology applications: SDS is commonly used in techniques like SDS-PAGE (polyacrylamide gel electrophoresis), which is used to separate proteins based on their molecular weight. It is also used as a component in Western blotting, a technique used to detect specific proteins in a sample.

Pharmaceutical industry: SDS is utilized in the formulation of certain drugs, including creams and ointments, where it aids in the solubilization and dispersion of active ingredients.
