Hello all! I am asking this question for a friend. She has about a quart of rendered goose fat that she found in her freezer that has gone rancid. She's wondering if it would be okay to use for soap making if she does 0% superfat as she read somewhere that it was okay to. I recommended adding citric acid too as a preservative. My friend is also wondering how she should incorporate the fat into a recipe.

I came up with this:
Goose Fat 45%
Lard 30%
Coconut Oil 20% (Yes, I know that's high for some people)
Castor Oil 5%

0% Superfat
33% Lye concentration
Citric acid at 3% of oils

Let me know what you think. Thanks in advance!

Looks okay to me but I would skip the lard and use all goose fat.

I would also use the Search feature located in the upper right corner of this page to read threads about using "rancid oils". It has been discussed many times before.
