Kemsurf CA
Product Category: Anionics
Calcium Dodecyl Benzene Sulphonate (Calcium Dodecylbenzenesulfonate)
INCI Name: Sodium Lauryl Sulfate
Kemsurf CA is an anionic surfactant based on calcium dodecyl benzene sulphonate, supplied as a solution in organic solvent. It provides effective emulsification, wetting, and detergency, making it suitable for a wide range of industrial and formulation applications.
Kemsurf CA is a hydrophobic surfactant designed for use in oil‑based and solvent‑based systems, where it functions as a highly efficient emulsifier for oils, waxes, and aromatic solvents. It delivers good surface activity, enabling stable emulsification and dispersion of hydrophobic materials.
The product offers good compatibility with anionic and nonionic surfactants and maintains stable performance across a range of conditions, including alkaline, mildly acidic, low electrolyte, and hard or soft water environments. Its versatility makes it particularly well suited to agrochemical, degreasing, and speciality industrial applications.
