yes, that sounds right to me. As I understand it, the stearic also helps maintain the emulsion, although the soap is the primary emulsifier.
After the big shredding process the other night, I remembered some 0-SF-100%CO stain sticks that were languishing in my laundry room (made waaaay to many of them). So, I grated those up, too. Altogether, my basic starting mix will consist of:
1. Four parts shreds from my regular CP soap recipe (lard, tallow, low CO, butter, soft oil, 2%SF)
2. One part shreds from my (former) shave soap recipe (dual lye, high tallow, stearic acid, low CO, butter, 5%SF)
3. One shy part gratings from my stain-stick recipe (100% CO, 0%SF).
I'm hoping create something that melts down easily, bubbles well, isn't too drying, and doesn't require lots of expensive ingredients. Yes, I want it all!
I'm not sure I'll add any stearic acid to start since the shave soap has quite a bit, and my regular recipe has some.
After watching her entire sugar scrub playlist, there were definitely nuggets along the way that will help inform my experiments. For instance, per this other video of hers
, if my initial mix doesn't bubble well enough, I'll try adding some melted SCI+CapB. That's essentially what I did with the last batch; I started with the jelly soap base, but it didn't bubble well enough, so I added in some of the DIY B&B scrub base - which includes SCI + CapB, among other things. Had I found her video first, that process would have been much faster, but I'm actually happy that I figured it out on my own, and then found someone else confirming it.
Good luck with yours, and please let us know how it turns out!
edit: Here are my recipe notes from her video:
Start with soap shreds.
Add 50-100% water, depending on how dry or soft the shreds are.
Add 50-100% glycerin, depending on how cleansing or conditioning the shreds are.
Add up to 10% soft oil but probably reduce the water or glycerin a bit.
Using the total weight of the combined shreds + water + glycerin, add 10-30% stearic acid.
Melt it all together.
Let cool completely, then whip.
To thin it out, add more water or glycerin.
To thicken it, add more melted stearic, let it cool, and rewhip.
Add 50-100% sugar.
