Caustic Soda for Soap and Detergent
Caustic soda is the alkali behind soap making and behind a long list of detergent intermediates including formic acid oxalic acid borax phenol sodium cyanide synthetic fatty acid and synthetic detergent.
Industry Pain Points
What Goes Wrong With The Wrong Supplier
- A variable alkali strength changes the free caustic figure in the finished bar
- Carbonate carried in with the alkali consumes reagent without doing work
- Batch tanks are slow to reach strength when the solid dissolves poorly
- Retail brands need their own printed packaging on the incoming raw material
Customer Requirements
What This Industry Actually Needs
- 99% purity with carbonate declared at 0.5% maximum
- A form that dissolves quickly in a stirred make up tank
- Bag sizes matched to the batch size so part bags are avoided
- Customised packaging where the buyer resells or repacks

Soap and Detergent Questions
Answers to the questions buyers ask us most often before placing a first order
Carbonate is not active alkali for saponification, so a high carbonate figure means you are buying weight that does no work. We declare carbonate at 0.5% maximum.
Yes. Customised packaging and labels are accepted. Send the artwork and bag size with your enquiry.
Flakes. They present more surface area per kilogram than pearls, so a stirred tank reaches working strength faster.
