Sodium Lauryl Sulfate Powder
Sodium Lauryl Sulfate (SLS) is an anionic surfactant commonly used in shampoos, toothpastes, and foaming cleansers. It meets the Chapter 34 definition for organic surface-active agents by reducing surface tension in water solutions to below 45 dyne/cm. Classified under 3402.39.90 as a non-soap anionic agent not put up for retail sale.
Linear Alkylbenzene Sulfonic Acid (LABSA)
LABSA is a primary anionic surfactant used in liquid laundry detergents and industrial cleaners. It qualifies as an organic surface-active agent under heading 3402 by forming stable emulsions and reducing water surface tension. Falls under 3402.39.90 as 'other' anionic agents.
Sodium Alpha Olefin Sulfonate (AOS)
AOS is a foam-boosting anionic surfactant derived from alpha olefins, used in shampoos and hand soaps. It passes the 3402 surface-active test by creating translucent solutions. Classified in 3402.39.90 as other anionic agents.
