black African Natural cocoa butter. It's so much easier to chop into little pieces than regular cocoa butter because it's softer with a lower melting point. My knife just cut into this cocoa butter - normally, I wish for a hammer when I'm breaking up cocoa butter for a recipe! - and it melts very quickly in the double boiler.
Naturally, I had to make myself a solid scrub bar with salt for my shower. I found it melted a lot quicker than my normal scrub bars, but that made it deposit a lot more cocoa butter deliciousness on my skin, and I could still smell the faint yumminess of Cream Cheese Frosting fragrance oil after work. The 60 gram bar will last me two showers instead of three, but I think it worth it for the lovely moisturizing I felt all day! The only down side is that you will end up with some brownish spots on your shower - just spray them with the nozzle and they'll disappear.
I think I'm going to package these for Christmas gifting with a drizzle of pink or purple mica on top and put them in a cellophane bag to make them look like a big bonbon! I will also include a sign that says in giant pink letters DO NOT EAT because it looks and smells amazing (I know, I take terrible pictures, but it really looks lovely).
If you want the bar to be a bit harder, use 30% black cocoa butter and 20% regular cocoa butter and use a harder butter for the other 20%. I'd go with mango or one of the other exotic butters over shea as that will be far too soft.
SOLID SCRUB BAR FOR THE BODY
50% cocoa butter
20% mango, shea or other butter
3% cetyl alcohol
4% Incroquat BTMS or Incroquat CR
2% wax of choice - beeswax, soy wax, etc. For candellia wax, please use 1% as it is very hard.
3% sodium lactate (as a bar hardener, optional)
1% fragrance oil
1% Vitamin E (if you are using oils with less than 6 months' shelf life)
Add up to 100% sugar, salt, beads, seeds, loofah, and so on. It really is your preference. If you are using sugar, you may need to add more than 100% because the sugar will melt into the warm oils - if you can stand the waiting, let it cool a bit before adding the sugar. You can add the salt right away into the hot oils. It will melt slightly, but not enough to be concering. Clay and jojoba beads will melt in the hot oils so you will need to let the mixture cool a lot - they really aren't a great choice here because you'll have to wait so long, the bar might actually solidify while you're waiting for the right temperature. Personally, I'd leave those for oil based or emulsified scrubs.
