That ratio really does not mean anything when I say slow moving oils. If you do a search for slow moving or oils for doing swirls you will get a better idea of what oils I'm talking about. Here is the recipe that I use and depending on the FO that I use, I will get 5-10 minutes before the batter starts getting thick.
Lard, Pig Tallow (Manteca)
Coconut Oil,
Palm Oil
Safflower Oil,
Castor Oil
Sodium Lactate
Butters don't always behave like you think they will. Even if you force gell them they can remain soft for days. I gave up using them but other people have good luck using them
@KiwiMoose is one of the people.
I wrap my soap in heating pads to force gell them and with the recipe above, I can unmold and cut the soap after 14-24 hours. I get my soap up to 150°F and when I reach that temperature I uncover the soap and set it aside to cool down. I can even go to 160°F without a problem but it depends on your recipe and I have used this recipe for a year and I know how it behaves and what it will do as it gets hot. I also use sodium lactate to help it harden in the mold.
