Abeson is an anionic surface active agent with superior detergency and compatibility with a broad range of other anionic, nonionic and amphoteric surfactants. It is highly efficient versatile surfactant suitable for use separately as detergent in acidic environments.

As intermediate it is usually neutralized with various bases to produce sulfonates that are used in numerous industries, most commonly in the production of liquid and powder detergents, household and I&I cleaners, laundry detergents, dishwashing liquids, car wash products, hard surface cleaners etc. Besides these Abeson is applied in various industrial applications such as agriculture, emulsion polymerization, oil field chemicals etc.
