P. Hydroxide

[CaliChan]

I have found alot of sodium hydroxide but i dont even know were to start looking for p. hydroxide so that i can start making liquid castile soap. What would it be marked as? and what are some common brands? I dont like to order things online.

I doubt very much that you'll be able to find it anywhere except online. At least that has been my experience.

You should be able to find if from a chemical supply company if you are prepared to buy it in 50 lb bags. Otherwise online works pretty well. Before I did the 50 lb bags I used to order it from:

I asked at the local Ace Hardware and they can order a bag for me. It is used as a fertilizer. She looked it up and it is 100% potash. I haven't ordered it yet, though. I wanted to have success with bar soap before spending more $.

Yes I was going to suggest Lowes or home depot

Look up any of your local science/lab supply stores as well. They may charge more, but most often you can get small amounts (not 50 lb. bags) :shock: and higher purity. Most of us use NaOH that are 99+ % pure, and I would expect you want the same or at least 98+ % pure POH.
