Sodium Hydroxide (Caustic Soda) 1KG

If you’re taking up natural soap making or stocking up on your supplies, sodium hydroxide, or caustic soda (Formula NaOH), is a vital ingredient you will need.

Our 1kg sodium hydroxide guarantees purity of lye. As it is packed by our team in-house, it undergoes no mechanised bottling, so there is no chance of contact with traces of hydrated silica powder.

This product is formally known as Sodium Hydroxide (Caustic Soda) Premium Quality and is considered ‘Dangerous Goods’ (UN1823) for transportation. This means restrictions for shipping apply. Read our extended info for more information or get in touch with our friendly team.

Sodium hydroxide is an essential ingredient for real soap making, and our 1KG option is perfect for wholesalers or personal projects where smaller quantities of soap are being made. 

As this is a corrosive product, special care should be taken when handling it. You can find information on the label provided. 

Due to its corrosive nature, we are unable to send sodium hydroxide through regular post. Instead, your delivery will arrive by an independent carrier, so minimum charges will apply. To keep your shipping charges at our standard rate, we’d recommend including sodium hydroxide as part of a larger order. 

Shipping regulations with sodium hydroxide in Europe mean we can pack a maximum of 30 x 1kg packs (within an ‘outer pack’) in a single shipment. This product can be sent via road service only.
