I would try a small batch first. You might want to use
cetearyl alcohol and emulsifying wax. Melt the e-wax and
cetearyl alcohol, add to the scrub base and mix well. If your e-wax and cetearyl alcohol seem a little stiff upon melting, you can heat it with a little oil. If you try it on a small batch you won't lose much if it doesn't work. Here is a sample recipe from Humblebee and Me, Check her percentage of cetearyl alcohol and emulsifying wax to get an idea of how much to use with your base.
Watermelon Mint Whipped Sugar Scrub
Heated Phase
9g | 9% Emulsifying Wax NF (USA / Canada / AU) or Polawax (USA / Canada)

Post-heat phase
49g | 49% white sugar (
USA /
Canada)
Cool down phase
0.25g | 0.25% Vitamin E MT-50 (

Canada)
0.2g | 0.2% peppermint essential oil (

Prepare a water bath by bringing about 3cm/1″ of water to a bare simmer over low to medium-low heat in a wide, flat-bottomed sauté pan.
Weigh the heated phase ingredients into a medium-sized, deep, heat-resistant mixing bowl. Place the bowl in your prepared water bath to melt everything through.
Once the mixture has melted, remove it from the heat and stir in the sugar. Freeze the mixture in the bowl for five minutes, and then remove it promptly. Grab your electric mixer, and whip up the mixture for about 3 minutes, until it is fluffy and uniform.
Leave the scrub to fully cool to room temperature and then whip it again—I like to do the last whipping at room temperature to make sure it’ll stay nice and fluffy at room temperature. During this final whipping, you’ll weigh out the cooldown phase and whip that in as well.
