Description

Sodium xylenesulfonate (CAS 1300-72-7 ), commercially known as SXS or Naxonate, is an anionic hydrotrope used across detergent, personal care, and industrial cleaning formulations. It increases the solubility of other surfactants and active ingredients in aqueous systems, allowing formulators to achieve higher active concentrations without phase separation or viscosity problems. In liquid detergent and hard-surface cleaner manufacturing, SXS is used to boost the loading of anionic and nonionic surfactants, enabling concentrated, stable products for various markets. Personal care formulators incorporate it into shampoos and body washes to improve clarity and flowability of high-surfactant blends. This ensures a consistent user experience and product quality. Textile and leather processing operations use SXS as a coupling agent and dispersant to ensure uniform dye penetration and consistent bath stability during the manufacturing process. In agricultural formulations, it supports the dispersion of active ingredients in liquid concentrate products, improving homogeneity and shelf stability for long-term storage and application. Sodium xylenesulfonate is supplied as an aqueous solution, most commonly at 40% and 45% active concentrations, and as a dry powder or granule form for applications requiring low moisture content. Standard grades include technical and industrial, with some suppliers offering specifications aligned with detergent-industry requirements. Bulk liquid supply in IBC containers is standard.
