Important Notice

1. Caustic soda is a strong alkali material, it can absorb moisture to deliquesce or absorb carbon dioxide to deteriorate when exposed in the air

2. In most applications, caustic soda is used in solution status, but for exporting and importing, it's suggested to use solid form to save the packing cost and transportation cost

3. There are mainly 3 solid types:

a) Solid (packed in drums, purity cca. 96%)

b) Flakes (packed in bags, purity cca. 99%)

c) Pearls (packed in bags, purity cca.99%)

Among the 3 forms, flakes and pearls are mostly widely used

4. We normally list 2 years as the shelf life in our COA, the real shelf life is actually longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
