As an anionic surfactant, sodium dodecyl sulfonate (SDS) is widely used inlaundry detergents, dishwashing liquids, and household cleaners. Its hydrophilic sulfonate group (−SO3Na) and hydrophobic dodecyl chain enable it to reduce surface tension, emulsify oils, and disperse dirt, enhancing the cleaning efficiency. It is often formulated with other surfactants to improve foaming and degreasing properties.
2.Emulsifiers in Industrial Processes
In industries likepetroleum, paint, and textile, SDS acts as an emulsifier to stabilize oil-in-water emulsions. For example, in emulsion polymerization (e.g., production of synthetic rubbers and latex paints), it helps disperse monomers and prevents particle aggregation, ensuring uniform product quality. In textile dyeing, it improves the solubility of dyes and promotes even coloration.
