Kemsurf PWS

Kemsurf PWS is an anionic surfactant based on isopropylamine dodecyl benzene sulphonate, derived from a linear high 2‑phenyl alkylbenzene sulfonic acid.

​

The isopropylamine salt structure provides enhanced solubility in hydrocarbon solvents compared to conventional sodium-based grades, making it particularly suitable for solvent-based formulations, oil-phase systems and fuel-related applications.

​

Kemsurf PWS combines high surface activity with strong emulsification and wetting performance, enabling efficient incorporation of water and actives into hydrocarbon systems. It is widely used where multi-phase compatibility, detergency and formulation stability are required across industrial applications.

​

Key Features

​

• Enhanced Solubility in Hydrocarbon Systems - The isopropylamine salt form provides superior solubility in hydrocarbon solvents compared to sodium-based equivalents, enabling effective use in solvent-based and oil-phase formulations.

• Strong Emulsification & Detergency Performance - As a high-active anionic surfactant (~90% surface active matter), Kemsurf PWS delivers excellent emulsification and detergency performance in solvent-based and mixed-phase systems.

• Versatile Compatibility Across Solvent Systems - Kemsurf PWS is compatible with water, hydrocarbons and a wide range of organic solvents, including ethanol, mineral oil, white spirit and aromatic solvents.

​

Applications

​

Kemsurf PWS is used across a wide variety of industries where hydrocarbon compatibility, emulsification and detergency performance are required:
