Sodium xylene sulfonate is an effective coupling/hydrotrope for water solutions of various surfactants and hydrophylic solvents.Sodium xylene sulfonate is used in liquid detergent. They are effective in promoting the compatibility of various ingredients present in a multi-component system. It is used as an electroplating bath additive and as viscosity reducer for concentrated liquid detergent and as solubilizer and cloud point depressor. SXS (Sodium Xylene Sulfonate) is commonly used as a hydrotrope. Since SXS has no detergency, Amphoteric or Phosphate Ester surfactants which contribute both detergency and hydrotroping power to the cleaner are used in high performance formulations.
