My favorite to just whip up around the house is just Brown Sugar w/ any oil (Sweet Almond is nice but any light one will do). Just mix enough oil in to make the brown sugar stick together and you when you use it. A bit of vit. E just because I like it & fragrance as desired (If you use a light oil you really don't need this if you don't want it). It keeps for a long time and works well.
I use (and sell) a combination of sugars, sweet almond oil, grapeseed oil, jojoba oil and essential oil.
The EO vary depending on what you want. Peppermint is nice for a zingy, wake-up scrub. Lavender, neroli and chamomile is lovely for a relaxing scrub (good just before going to bed!). Lavender and lemon makes a nice combination, too.
I made a scrub last night and used it this morning. I used brown sugar, almond oil, grapeseed oil, and vit. E oil, along with orange and lavender EOs. It is nice, but not quite right. The texture just isn't the same as my store-bought scrubs. I wonder if there's another ingredient to make it less sugary-sticky?
