Caustic soda flakes are solid sodium hydroxide with 96–99% purity. They are lightweight, easy to store, have a longer shelf life, and are more cost-effective to ship internationally. Liquid caustic soda is a 32–50% NaOH water solution that is easier to dose, dissolve, and handle in continuous industrial processes. Flakes are preferred for soap manufacturing, textile processing, and export shipments, while liquid NaOH is ideal for water treatment plants, chemical dosing systems, and refinery operations.
