Kemsurf CA, a calcium salt derived from biodegradable dodecylbenzene sulfonic acid, is manufactured through SO3 sulphonation, resulting in a product with low inorganic content and an appealing color. It serves as a hydrophobic anionic surfactant, primarily employed as an emulsifier for oils and aromatic solvents in degreaser formulations. Its versatile applications span from pesticide and herbicide systems, particularly in spray applications, to emulsifying waxes and hydrocarbon solvents. With compatibility with other anionic and nonionic surfactants, Kemsurf CA maintains stability, detergency, foaming power, and soil suspension in diverse conditions, including alkaline, mild acid, low electrolyte, and both hard and soft water settings.

Features & Benefits

  • Kemsurf CA is a hydrophobic anionic surfactant and functions as an emulsifier for oils and aromatic solvents in the formulation of degreasers. It finds many applications, however, as an emulsifier for pesticide and herbicide systems, especially were spray application is involved.
  • Kemsurf CA may also be used in the emulsification of waxes and hydrocarbon solvents. This product has good compatibility with other anionics and nonionic surfactants and maintains good stability, detergency, foaming power and soil suspension in alkaline, mild acid, low electrolyte and in hard or soft water.
