Sodium p-dodecylbenzenesulfonate

Description:
Sodium p-dodecylbenzenesulfonate, with the CAS number 2211-98-5, is an anionic surfactant commonly used in various applications, including detergents, emulsifiers, and wetting agents. It features a hydrophobic dodecyl chain attached to a benzene ring, which is further substituted with a sulfonate group, imparting its surfactant properties. This compound is characterized by its ability to lower surface tension, making it effective in enhancing the solubility of hydrophobic substances in aqueous solutions. It is typically a white to pale yellow solid or powder and is soluble in water, forming micelles that facilitate the dispersion of oils and greases. Sodium p-dodecylbenzenesulfonate is known for its stability across a range of pH levels and temperatures, although it may be sensitive to high concentrations of electrolytes. Its applications extend to the formulation of cleaning products, personal care items, and industrial processes, where it aids in emulsification and foaming. Safety data should be consulted for handling and potential environmental impacts, as with all chemical substances.
