Unlike scrubs made with only oils and sugar, emulsified sugar scrubs become a creamy lotion upon contact with water, leaving soft skin and no oily residue behind.
Weigh out ad mix together the first 5 ingredients: the oil (but not essential oils), butters, and waxes.
Melt the oils, butters, and waxes over a double boiler (or in the microwave, if you prefer).
Once melted, remove from the heat, and stir occasionally as the mixture cools. You can use a mixer to help blend everything together and make a creamy mixture, but it's not essential.
Once your mixture has cooled down quite a bit (ideally below 45ºC/115ºF), you can begin to add the essential oils and preservative.
Make sure the essential oils and preservative are well incorporated into your oils and then begin to add the sugar. Add slowly, and stir constantly, so you can gauge the consistency of the product. Add as much sugar as you like to achieve the desired consistency. (I like it somewhere between 120-150g.)
To use your sugar scrub, scoop out a small amount in your hands and begin to rub over your wet arms and legs (or any areas you want to exfoliate and hydrate) in a circular motion. As the mixture comes into contact with the water, a lotion will be formed, and the sugar will begin to dissolve, making the product smoother and less abrasive. Rinse any remaining sugar crystals off, and pat your skin dry. Your skin should now feel smooth and hydrated.
