Linear Alkylbenzene Sulfonic Acid (LABSA)
LABSA is a synthetic anionic surfactant used as a primary ingredient in laundry detergents and industrial cleaners. It meets the Chapter 34 definition for organic surface-active agents by forming stable emulsions and reducing surface tension when diluted in water. Classified under HTS 3402.90.50 as a pure surfactant other than soap.
