Overview
Caustic Soda Lye is the liquid form of sodium hydroxide (CAS 1310-73-2) — also called liquid caustic soda or caustic lye — supplied as a colourless to slightly coloured liquid for buyers who dose NaOH directly rather than dissolving flakes on site. It covers the same core uses as our flake grade — pH correction and neutralization in water and wastewater treatment, soap, detergent and textile manufacturing, the Kraft pulping process, and general chemical manufacturing feedstock — and ships in HDPE carboys and drums, IBC totes, or bulk tanker for plants that consume it in volume.
