Sodium dodecyl sulfate has a good emulsification, foaming, water-soluble, biodegradable, alkali-resistant, hard water-resistant, and is stable in a wide pH aqueous solution and easy to synthesize, low price, etc. It is used in cosmetics, detergents, textiles, paper, lubrication and pharmaceutical, building materials, chemical, oil and other industries. It can also be applied to the properties of positive and negative ion surfactant compounding systems, micelle catalysis, molecular ordered assemblies, etc. Research.
1. Sodium dodecyl sulfate is used as a detergent and textile auxiliaries, and also as a toothpaste foaming agent, a mine fire extinguishing agent, an emulsion polymerization emulsifier, a wool detergent, and the like.
2. Sodium dodecyl sulfate is a processing aid for the food industry. Used in cakes, beverages, protein, fresh fruit, fruit drinks, edible oils, etc.
3, Sodium dodecyl sulfate is a commonly used ionic detergent, which can disintegrate the cell membrane, bind to the hydrophobic part of the membrane protein and separate it from the membrane. High concentration of SDS can also destroy the ionic and hydrogen bonds in the protein. Wait for non-covalent bonds and even change the conformation of the protein. This property is commonly used for SDS gel electrophoresis of protein component analysis.
