I was wondering why my soap wasn't tracing after like thirty minutes, then I realized I had used potassium hydroxide instead of lye! So now I'm wondering if there's any way to save this batch. I ran my recipe through soapcalc again, this time with Potassium hydroxide, and it called for 122gm more than the lye I used. Has anyone else ever done this?

Potassium hydroxide is used to make liquid soap. I would cook it, dilute it, then use it for cleaning around the house. Adding sodium hydroxide to this would make your soap lye heavy.

But won't I have too little KOH? Soapcalc said 303gm of lye, but 425gm of KOH for the same recipe. Since I used KOH, shouldn't I use 425gm?

I actually bought the KOH a while back, planning to try making liquid soap, but I forgot I had it until the no tracing thing happened. I wasn't planning on trying it by accident though! Lol! :oops: Should have read the label!

Thanks for your help

If you have less lye then the recipe called for, the soap will be more superfatted. Since it's already made, I wouldn't mess with it. How does it feel?

It's still in the pot and really kind of watery. I was superfatting 8%.

I'm thinking if I leave it out I'll end up with like a 30% superfat. I guess I might as well try adding it and see what happens. So far, I've never made a soap mistake I couldn't fix, but I've never made a mistake like this before! I'd better start looking for a big container in case it comes out ok. Was not planning to make 5lb of liquid soap right now. Another adventure!
