Product Details
Dodecylbenzenesulfonic Acid Sodium Salt is typically supplied as a white to pale yellow powder or granules, while industrial-grade products may exhibit a light brown tint due to trace impurities. It has a mild odor profile without any pronounced or irritating smell, making it suitable for various industrial formulations. The product is hygroscopic and may absorb moisture during storage, occasionally resulting in slight caking or agglomeration. However, under normal application conditions, this physical change generally does not significantly affect its solubility, dissolution performance, or functional effectiveness. Proper packaging and moisture-controlled storage are recommended to help maintain product quality and handling convenience.

Product Usage
Sodium dodecylbenzene sulfonate is a versatile anionic surfactant extensively used in household cleaning and personal care formulations. It is commonly incorporated as a key cleansing ingredient in laundry powders, liquid detergents, dishwashing liquids, and body washes, where it can account for approximately 40%–70% of the active surfactant components in certain formulations. With its excellent detergency, emulsifying, and dispersing properties, it effectively removes grease, loosens dirt, and helps suspend contaminants in water for easy rinsing. Its reliable cleaning performance and broad formulation compatibility make it an important raw material in the manufacture of everyday cleaning products.
