Sulphonic Acid (LABSA) 90%
Sulphonic Acid, commonly known as Linear Alkyl Benzene Sulphonic Acid (LABSA) 90%, is a high-quality anionic surfactant widely used as a key raw material in the detergent and cleaning products industry. It is produced by sulfonation of linear alkyl benzene, resulting in a biodegradable, highly effective wetting and foaming agent. The 90% concentration grade offers excellent performance in formulation of powders, liquids, and specialty detergents.
