Property and application
Sodium dodecyl sulphate sds is a white crystalline powder, classified as an anionic surfactant. It exhibits excellent water solubility and good compatibility with both anionic and non-ionic substances, delivering superior emulsifying, foaming, penetrating, cleaning, and dispersing capabilities.
Widely utilized in toothpaste, shampoo, laundry powder, liquid detergents, cosmetics, plastic mold release, lubricants, pharmaceuticals, papermaking, construction materials, and various chemical industries, it demonstrates broad application potential across multiple sectors.
(Use 1) Used as a detergent and textile auxiliary agent, also used as a foaming agent in toothpaste, a mine fire extinguishing agent, an emulsifier in emulsion polymerization, and a wool detergent.
(Use 2) Used as an anionic surfactant, emulsifier, and foaming agent.
(Use 3) GB 2760-96 specifies it as a processing aid for the food industry. Foaming agent; emulsifier; anionic surfactant. Used in cakes, beverages, protein, fresh fruit, fruit juice drinks, edible oils, etc.
(Use 4) Used as an emulsifier in pharmaceuticals, cosmetics, and synthetic resins. Also used as a foaming agent in toothpaste and fire extinguishers. Used as a detergent for fine silk and wool fabrics. Used as a flotation agent in metal ore beneficiation.
(Use 5) Used as a detergent and textile auxiliary agent, also used as a foaming agent in toothpaste, fire extinguishing foam, emulsion polymerization emulsifier, pharmaceutical emulsifying and dispersing agent, shampoo and other cosmetic products, and wool detergent.
