Naxonate® 4ST is an ideal hydrotrope for liquid detergents, with similar coupling performance to sodium xylenesulfonate but lower sulfate and sulfone levels. It generates essentially no foam or wetting action and has minimal influence on surface tension, providing a cost-effective way to solubilize complex formulas, elevate cloud points, and control viscosity.

Storage & Handling

Storage Information
  • Store covered in a dry, well ventilated area. Keep container tightly closed when not in use. Prevent from freezing. This product will crystallize at 10ºC and may precipitate from solution during storage. Store material above 20ºC.
  • If material freezes, we suggest heating the material to 100 - 110ºF and agitate the container until material goes back into uniform solution. Material tends to settle when frozen, but overall quality is not impacted.
