Product Details
Sodium dodecyl sulfate (SDS), classified as an anionic surfactant, serves as a characteristic example of sulfate-based surfactants. Also commercially designated as AS, K12, sodium coco-sulfate, or sodium lauryl sulfate, it is widely utilized as a foaming agent. Market formulations typically appear as white to pale yellow crystalline powders that are non-toxic. This compound demonstrates limited solubility in alcohol while being insoluble in chloroform and ether, though it readily dissolves in water. SDS exhibits excellent compatibility with both anionic and nonionic compounds.
The surfactant displays superior emulsifying, foaming, wetting, cleaning, and dispersing properties, producing abundant foam while undergoing rapid biodegradation. However, its aqueous solubility is comparatively lower than that of sodium alcohol ether sulfate (AES).
Sodium Dodecyl Sulfate (SDS) (C₁₂H₂₅SO₄Na, CAS 151-21-3), classified as an anionic surfactant, is the benchmark sulfate-based surfactant. Also designated as AS, K12, sodium lauryl sulfate (SLS), or sodium coco-sulfate (C12-C16 chain blend), it typically appears as white to pale yellow hygroscopic crystals with a characteristic faint fatty odor.
Sodium dodecyl sulfate is highly effective in cleaning, emulsification, and foaming. It serves as a detergent and textile auxiliary, and is widely used in various applications, including as anionic surfactants, toothpaste foaming agents, mine fire extinguishing agents, fire extinguishing foams, emulsion polymerization emulsifiers, and pharmaceutical emulsifying dispersants. It is also used in cosmetics such as shampoos, wool detergents, and detergents for fine silk and wool fabrics. Additionally, it functions as a flotation agent in metal beneficiation.
According to GB 2760-96, it is recognized as a processing aid in the food industry, where it acts as a foaming agent, emulsifier, and anionic surfactant. It is used in products such as cakes, beverages, protein, fresh fruits, fruit juice drinks, and edible oils.
