The first difference is that you have to choose your oils carefully. In normal cold process soap making, you can vary your oils, choosing a balance between soft and hard (at room temperature) oils. I like to use about 60/40 ratio. This would be 60% "hard" oils like coconut, palm, lard, tallow
, palm kernel, shea butter, cocoa butter, shortening etc. and 40% "soft" oils like canola, olive, rice bran, soybean, etc.
But with the room temperature/whipped process, you want a very high percentage of hard oils - it's best to use about 80%. You need this percentage of hard oils to get the "whipped" effect.
For this batch, my recipe was:
- 25% Lard
- 30% Coconut
- 25% Palm oil
- 15% Olive oil
- 5% Castor oil
