Benzenesulfonic acid, 4-dodecyl-, potassium salt (1:1)

Description:
Benzenesulfonic acid, 4-dodecyl-, potassium salt (1:1), commonly referred to as potassium dodecylbenzenesulfonate, is an organic compound characterized by its long hydrophobic dodecyl chain and a hydrophilic sulfonate group. This amphiphilic nature makes it an effective surfactant, allowing it to reduce surface tension in aqueous solutions. The compound typically appears as a white to off-white solid and is soluble in water, which enhances its utility in various applications, including detergents, emulsifiers, and dispersants. Its structure features a benzene ring substituted with a dodecyl group at the para position and a sulfonate group, contributing to its surfactant properties. The potassium salt form provides stability and solubility in water, making it suitable for use in formulations requiring ionic surfactants. Additionally, it is often employed in industrial processes, personal care products, and agricultural applications due to its effectiveness in stabilizing emulsions and enhancing the wetting properties of formulations. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.
