Calculate potassium hydroxide

[DeeAnna]

Shaan -- I think I may be wrong in Post #18. Susie and I are having a PM confab about the differences in our numbers and hope to figure out where things went awry. More soon....

 

[Susie]

I think DeeAnna is right on the numbers. I am no longer sure exactly how I got the number I did...

 

[DeeAnna]

Nope, I can't let Susie take all the responsibility, because I'm getting numbers that are different than what I've gotten before. I've done something screwy, but I can't figure it out. Here is what I did today --

I went to soapcalc and put in Shaan's recipe from Post #3 with 3% superfat:

Canola Oil 75.00 g
Castor Oil 75.00
Coconut Oil 75.00
Rice Bran Oil 50.00
Olive Oil 175.00
Sunflower Oil 50.00
Totals 500.00 g

Super Fat/Discount 3 %
Lye Concentration 25.0000 %
Water : Lye Ratio 3.0000:1

I did not check the 90% KOH button. I got these numbers back:

Water 286.27 g
Lye - KOH 95.42 g

When I adjust the KOH to allow for Shaan's 85% purity KOH, I get this for the actual KOH:

95.42 * 100 / 85 = 112.3 g

If you would please doublecheck my numbers, Shaan, I would appreciate that. I might easily have made a mistake.

I am so confused now..i hate maths too.

 

[DeeAnna]

Well, somewhere in the muddle there is the correct answer, but at this point I don't know if any of us know how to find it.

Suffice to say, you have made a LS that is working for you, right? That's the proof of the pudding!

Let's leave the math for another time. I apologize for my part in all this confusion and muddling up.

Yes i am happy with this calculation.. next time i will try with the 112.3g, if it makes any diff. But thanks so much for your replies.. you people are rocking!! So helpful and just amazing each time.
