Products Description of Sodium Xylene Sulfonate CAS#1300-72-7
Sodium Xylene Sulfonate is a liquid surfactant that ranges from white to light yellow in color and dissolves really well in water. In a 1% solution, it has a neutral pH of 7.0, with a viscosity of 10 mPa·s and a kinematic viscosity of 2.7 mm²/s at 20°C.
It's a real workhorse in the industry, serving as a coupling agent, solubilizer, cloud point depressant, detergent booster, dispersant, emulsifier, hydrotrope, and viscosity regulator. You'll see it in everything from shampoos and dish soaps to dry-cleaning agents, hard surface cleaners, metal cleaners, bactericides, adhesives, dyes, electroplating baths, cutting oils, photographic materials, inks, textiles, leather goods, and many other products.
