Linear Alkyl Benzene Sulphonic Acid, or LABSA for short, has been the world's largest-volume synthetic surfactant used in the detergent industry for decades. It's a very cost-effective anionic surfactant with excellent cleaning power and compatibility with other types of surfactants.
LABSA has been the dominant active matter of synthetic detergent powder since it was developed to become a biodegradable replacement for Nonlinear Alkyl Benzene Sulfonate (BAS). It can be stably dried into a powder form, and it can also easily dissolve in water to formulate many kinds of detergents in liquid and gel form, such as Dishwashing Liquid, Laundry Detergent Liquid, and Hand Soap Liquid.
