Liquid vegetable shortening in making bar soap?
Can I use a liqiud vegetable shortening in making bar soap?
As long as you know what vegetable the oil is made from and what the SAP value is of that oil, I see no problem.
You can make soap from any oil. It's the combinations of oils that make a soap really great.
If the oil is a blend then you will have a hard time determining the SAP value since you can't know how much of each oil is present in the shortening.
