Sodium Dodecylbenzenesulphonate, commonly known as SDBS, with the CAS number 25155-30-0, is a widely recognized and highly effective anionic surfactant. It plays a crucial role in numerous industrial and household applications due to its excellent surface-active properties. SDBS is typically supplied as a white to yellowish powdery particle, offering ease of handling and formulation.

Chemically, SDBS is characterized by the formula C18H29NaO3S. Its structure features a hydrophobic dodecylbenzene group and a hydrophilic sulfonate group, which together enable its surfactant capabilities. This molecular design allows SDBS to lower the surface tension of liquids, facilitate the mixing of oil and water, and effectively remove dirt and grease, making it indispensable in cleaning and emulsifying processes.

The specifications of high-quality SDBS are critical for its performance in various applications. A typical product specification includes an assay (purity) of around 95%±2. Other important parameters are low levels of inorganic salt (typically ≤2%) and controlled water content (often ≥3%). The pH value of an aqueous solution of SDBS is usually in the range of 8 to 10, indicating its mild alkaline nature. It boasts a density of approximately 1.02 g/cm3 and a high melting point, typically above 300°C, highlighting its thermal stability. SDBS is known for its stability under normal storage conditions, which is essential for its long-term use in industrial settings.

The applications of SDBS span across a broad spectrum of industries. One of its most prominent uses is in the detergent industry, where it serves as a primary surfactant in laundry powders, liquids, and dishwashing formulations. Its ability to emulsify fats and oils and disperse dirt particles makes it highly effective in cleaning. Beyond detergents, SDBS finds application in the textile industry as a scouring agent and dyeing auxiliary. In agriculture, it can be used as an emulsifier in pesticide formulations. It also serves as an additive in the paper and printing industries, as well as in oilfield chemicals.
