Sodium Xylene Sulfonate (SXS)

Sodium xylene sulfonate (SXS) is an anionic surfactant and hydrotrope widely used in household, industrial, and institutional cleaning products. Its primary function is to enhance the solubility of surfactants and organic compounds in water, making it a valuable ingredient for formulating clear, stable liquid detergents and cleaners.

SXS acts as a coupling agent, reducing cloudiness and separating phases in concentrated solutions, while improving product performance and appearance. It does not significantly contribute to foam but enhances the effectiveness of foaming agents like sodium lauryl sulfate, making it an important supporting surfactant in many formulations.

Beyond cleaning products, sodium xylene sulfonate is applied in textiles, leather processing, and agricultural chemicals as a dispersant and solubilizer. It is also used in oilfield chemicals, paper processing, and personal care formulations, where it serves as a mild hydrotrope to stabilize blends of active ingredients. Cost-effective and versatile, SXS remains a staple in both consumer and industrial chemical formulations.
