Sodium dodecyl sulfate is an anionic surfactant, which is a white to light yellow solid (can be divided into needle or powder), is easily soluble in water, has good complexity with anionic and nonionic, and has good emulsification, Foaming, penetration, decontamination and dispersion properties. It is widely used in pharmaceuticals, papermaking, building materials, chemicals, textiles, oil production, cosmetics, detergents, toothpaste, shampoo, laundry detergent, plastic mold release lubrication and other industries. 

The functions and uses of sodium dodecyl sulfate:

1. It is mainly used as a foam-enhancing agent, cleanser, and wetting agent in cosmetics and skin care products (to make cosmetics come into contact with the skin as soon as possible to avoid being blocked by the skin oil). It is safer and has no acne-causing properties;

2. Use detergent, textile bleach additive and carpet dyeing agent;

3. Wool detergent;

4. Leather softener;

5. Used as a foaming agent for toothpaste and fire extinguishers;

6. Used as a steaming penetration agent in papermaking;

7. Oil well and mine fire extinguishing agent;

8. Emulsifier for polymerization of styrene butadiene and acrylic acid latex emulsion;

9. Emulsifiers for synthetic resins;

10. Flotation agent for metal ore dressing;

11. Biochemical analysis, ion pair reagents;

12. Used as anionic surface penetrant in pesticides, generally the amount added to water-soluble pesticides is between 0.1% and 0.3%, which can significantly increase the absorption of drugs by the leaves;

13. Sodium dodecyl sulfate is a commonly used ionic detergent that 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 bonds in the protein. Non-covalent bonds with hydrogen bonds, such as hydrogen bonds, may even change the conformation of proteins. This characteristic is commonly used in SDS gel electrophoresis for protein component analysis;

14. When used as a wetting agent in electroplating, the surface tension between the plating solution and the plating part can be reduced, hydrogen bubbles on the surface of the plating part can be removed, and pinholes can be prevented. It is generally used in nickel plating liquid;

15. It is used as a mortar admixture, which can reduce water, increase and ease, and retain water;

16. Production of cement as abrasive agent;

17. As a surfactant in the coating industry, the surface tension of the coating can be reduced, so that the coating can be better distributed on the surface of the object;

18. During the oxidation process of aluminum alloy, adding sodium dodecyl sulfate solution can reduce surface tension, making oxidant molecules more likely to contact metals and make the reaction tighter;

19. GB 2760-96 stipulates that it is a food industry processing additive. Used for cakes, beverages, proteins, fresh fruits, juice drinks, cooking oils, etc.;

20. Sodium dodecyl sulfate is a commonly used medicinal auxiliary material. It is an anionic surfactant and can be used as a lubricant for medicines, emulsifiers, skin penetrating agents, tablets and capsules, and lubricants. Wetting agents, etc.
