Kemsurf CA is a calcium salt of a biodegradable dodecylbenzene sulphonic acid. The base acid for Kemsurf CA is manufactured by SO3 sulphonation to produce a product of good color and low inorganic content. 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.
