Ammonium lauryl sulphate (ALS) is used as a cleansing agent that removes oil and dirt from skin and hair without drying it out. Some of our products (shampoo, body wash and hand wash) contain ALS as an alternative to sodium laureth sulphate (SLES) or sodium lauryl sulphate (SLS). Virtually all of it is immediately removed from skin and hair by the simple act of rinsing with water.
