· Lithium dodecyl sulfate application

· Field of medicine

· • As a pharmaceutical dispersing agent: lithium dodecyl sulfate has good surface activity, which can reduce the surface tension of the liquid, make the drug particles evenly dispersed in the liquid, prevent the drug particles from aggregation and precipitation, improve the stability and uniformity of the drug, and facilitate the storage and use of the drug. For example, in some suspension drugs, it allows the drug components to be better dispersed in the solvent, ensuring that the drug concentration is uniform for each dose.

· • For biopharmaceutical fine equipment cleaning: in the process of biopharmaceutical, the surface of the equipment is easy to residue proteins, peptides and other biological macromolecules. Lithium dodecyl sulfate can effectively remove these residual substances through its surface activity, avoid cross contamination, ensure the cleaning and normal operation of the equipment, and meet the requirements of Good manufacturing practice (GMP).

· Use in electrophoresis: Lithium dodecyl sulfate can replace sodium dodecyl sulfate (SDS) for electrophoresis at low temperatures in biochemical studies. It can make proteins denatured and negatively charged, so that they can be separated in an electric field. It is helpful to analyze the molecular weight and purity of proteins, and is useful in biopharmacological research and disease diagnosis

· Field of coating

· • As an emulsifier: Lithium dodecyl sulfate can be used as an emulsifier during paint preparation. It can reduce the surface tension of the oil-water interface, make the oil phase and the water phase form a stable emulsion system, help to evenly disperse the oily film-forming substances in the aqueous medium, improve the stability and storage performance of the coating. For example, in water-based latex paint, help the emulsion particles to exist stably and prevent the emulsion from demulsification.

· • Improve the leveling of the coating: This substance can adjust the surface tension of the coating, so that the coating can be better spread and leveling during the coating process, reduce flow marks, orange peel and other surface defects, improve the flatness and gloss of the coating。
