Caustic Soda (NaOH)
Sodium Hydroxide or Natrium Hydroxide (NaOH) also generally known as Caustic Soda which common name derives from its chemical identity as a sodium hydrate. It is an essential chemical produced through electrolysis process of brine (salt solution).
Normally produced in liquid form (48% concentration) which can be further processed into solid and flake form (98%). Caustic Soda is a waxy, white solid and readily absorbs water and forms aqueous solutions.
