FAQs
What pack sizes are available for caustic soda?
Standard pack sizes are 25 kg poly bag (flake), 5 L liquid, 20 L liquid, 200 L drum, and 1,000 L IBC. Bulk tankers are available through Custom Orders.
Are alkalis classed as dangerous goods?
Most concentrated alkalis are DG Class 8 (Corrosive). Diluted versions and cleaning blends are often non-DG. Each product page lists the exact UN number, hazard class, and packaging group.
Which alkali suits clean-in-place (CIP) cleaning?
Caustic-based cleaners handle the alkaline stage of a CIP cycle; food and beverage plants pair them with an acid stage and a sanitiser. See the food & beverage industry page for the full cycle.
How should concentrated alkalis be stored?
Follow Sections 7 and 10 of the SDS - corrosive alkalis need appropriate bunding, ventilation and separation from acids. Confirm compatibility before co-storing with other chemicals.
What's the difference between caustic flake and liquid?
Flake (solid sodium hydroxide) is concentrated and cheaper to freight but must be dissolved on site with care; liquid grades are ready to dose. Choose based on your handling setup and dosing equipment.
