Actually I've been playing around with soild scrubs for the last couple of days....
This is one with brown sugar.

I've made these with salt, but I think you could replace the salt with white sugar.

salt + granulated pomegranate seeds

salt + coconut (coloured with food colouring)

The basic recipe I used is the following
20 g cacao butter
20 g shea butter (can be replaced by coconut)
20 g baking soda
2 ML Mulsifan
