Product Description
Sodium xylenesulfonate (SXS) is a colorless to pale yellow clear liquid with excellent water solubility. A 1 wt% aqueous solution has a pH of 7.0, a dynamic viscosity of 10 mPa·s, and a kinematic viscosity of 2.7 mm²/s at 20 °C.
SXS functions as a hydrotrope, coupling agent, solubilizer, cloud-point depressant, detergent booster, dispersant, emulsifier, and viscosity regulator. It is widely used across household and industrial formulations — including shampoos, laundry and dishwashing detergents, dry-cleaning agents, hard-surface cleaners, metal-processing cleaners, disinfectants, adhesives, dyes and pigments, electroplating baths, metalworking fluids, photographic materials, inks, textile processing, and leather manufacturing.

Application Scenarios
Household and industrial liquid detergents. The largest end-use of SXS. As a hydrotrope and cloud-point depressant, it keeps concentrated laundry liquids, dishwashing liquids, all-purpose cleaners, and bathroom cleaners clear, low-viscosity, and phase-stable at low temperatures, while boosting detergency in high-electrolyte formulations.
Personal care. Used in shampoos, body washes, and liquid soaps for viscosity control, optical clarity, and surfactant-system stability.
Industrial and institutional cleaning. Formulated into hard-surface cleaners, metal degreasers, bottle-washing compounds, and CIP cleaners, where it performs reliably under high-alkaline, high-salt conditions.
Agrochemicals. Serves as a solubilizer and dispersant in herbicide and pesticide aqueous concentrates.
Textile, leather, and dyeing. Acts as a wetting and dispersing agent in textile scouring, dyeing, and leather processing.
Electroplating and surface finishing. Used as a wetting and leveling additive in electroplating baths.
Coatings, inks, and pigments. A hydrotrope and dispersant in water-based coatings and ink formulations.
