Linear Alkyl Benzene (LAB)

Linear Alkyl Benzene (LAB) is widely used as primary cleaning agent in household detergents due to its good biodegradability in the environment. LAB is sulfonated at downstream plants to produce Linear Alkyl Benzene Sulfonic Acid (known as LABSA), which is the most cost-effective surfactant available and mainly used in household laundry and cleaning products.
