So I was right in the middle of melting oils and mixing lye, when i realised i did not have enough lye!!! I would have had enough if I was making my usual size batch, but this was a bit bigger. So I just ran with it and made it anyway. I did have a bit of KoH here, so I topped up with a bit of that rather than just leave as-is.
Soap made, and cut, and it looks great, but now I'm running it all through soap calc to see what the numbers are, and it turns out that the difference between 30% lye concentration, and 28% lye concentration is absolutely minuscule in terms of the amount of lye required. So I adjusted the superfat in the calculator to find that I have a 28% lye concentration and a 16% superfat! ( that's without counting the KoH).
Essentially I needed 204g Lye and I only had 180g. I topped up with 20g KoH. How on earth do i crunch these numbers? Mathematicians please help!
What will the addition of KoH do? Just decrease the superfat? My soap set up just fine and cut just fine but it feels like it has more 'give' when i squeeze it than usual.
So in attempting to answer my own questions here, I've entered all my numbers into the soap calc to find that the closest I can get results in the following:
NaoH - 93% (178g), KoH 7% (20.8g)
This is approx 29% lye concentration with 11% superfat.
Will my soap always be soft with that amount of KoH? And that amount of superfat?
