Combine cocoa butter, shea butter, jojoba oil and emulsifying wax in the bowl of a stand mixer or other heatproof bowl.
Place bowl on top of a saucepan with simmering water. Allow mixture to melt fully, stirring with a spatula occasionally. Once fully melted, heat for 20 minutes.
Remove from heat and place in freezer. Remove when a “crust” has formed, about 20 min.
Whip scrub base at high speed until fully thickened and cooled, about 10 minutes. The mixtures will form very soft peaks.
Add essential oils and preservative. Mix briefly.
Using a spatula, gently fold in the sugar.
Divide scrub evenly into jars. Label and enjoy!
