Where to find caustic soda – around the world?
middle
Anywhere you live, wherever you go, be able to find your caustic soda, so that you never stop soaping 🙂
Since I left my home, I lived in three countries and every time I moved I had to resolve the enigma of where to find my caustic soda locally…
I start this post to gather information where to find caustic soda anywhere in the world – it will serve as reference to everyone!
PLEASE, HELP AND SHARE YOUR CAUSTIC SODA SOURCE in the comments – I will include them in the post with your signature.

Where to search for caustic soda
Many countries in the world have totally different regulations.
- In many it is used for drain opening or for painting cleaning, so it can be easily found in almost all hardware/DIY and drug stores (not pharmacies), or in large supermarkets in the cleaning products section.
- In some it is considered a dangerous substance and its selling is regulated. It is sold in pharmacies and drugstores only, often upon a presentation of your ID
You can also order caustic soda in
- a chemical supply company. Just search for chemical supplies in the respective language and you will find a supplier.
- an online soapmaking supplies shop – if you are living in a country with a large community of soapmakers, you are lucky, as there is always a number of these
How to identify a good caustic soda
Unless you order from a specialized store, you should know some basics on how to identify a good quality suitable for soapmaking. Generally, you can find
- white beads/pearls – these are pure, concentrated caustic soda
- a solution of caustic soda in distilled water – pure, but not concentrated
When buying your caustic soda, pay attention to the following:
- Caustic soda has to be pure – do check this – often it is used as an ingredient in drain opener products, which contain plenty of other chemicals you do not want to have in your soap… However, some of the drain opening products are pure caustic soda.
- Always check the ingredient list – do not buy it, unless it is 99% or more and pure white pearls/beads (no grey, no yelowish) – that is the color of pure caustic soda!
- The same applies to lye solution – found often at around 30.5% concentration (30.5% caustic soda, 69.5% distilled water) – buy only if the ingredient list states caustic soda and water – nothing else!

- Any Home Hardware in any province of Canada (thanks to Karine L!):”In Québec, it’s the only place I’ve found it to this day.
I found mine in a small town HH associate tool store I would have never thought to check if I hadn’t been given the Home Hardware clue from someone in the Prairies, I believe. It comes in 3 kg or (I think) 0.5 kg, as Lye Crystals/Cristaux de soude (English and French, of course!). It’s 23 $ and 7 $ respectively, so the smaller size is awesome to try it out and the bigger size is great when you get hooked!Big brand stores and grocery stores don’t carry lye, surprisingly enough. Maybe in the spring when people start gardening, but certainly not in the winter. That small town hardware store has just made a friend! - Halifax, Nova Scotia (thanks to Sonya Budge!): Home hardware stores, e.g. Tantallon Home Hardware

Caustic soda can be found pretty everywhere [my experience]

My experience:
Caustic soda difficult to find, considered dangerous primary chemical and its selling is controlled.

Hello!
I live in Belgium and as far as I know, the easiest way to find sodium hydroxide (natrium hydroxide here) is to buy it at a store called ‘kruidvat’. It’s a store that sells bath&body products and household products. They sell it as a drain cleaner in 500grams orange bottle, 99% pure. Same story for the Netherlands, believe that kruidvat is also the main place to get sodium hydroxide there. Hope this helps!

Any Home Hardware in any province of Canada, actually. In Québec, it’s the only place I’ve found it to this day.

This is a great initiative, it took me a while to figure out where to go…
