Here is a body scrub recipe which appears in the March 2011 issue of Martha Stewart Living. The list of ingredients include body oil from Burt's Bees; Epsom salt, sea salt, or organic cane sugar; lemon zest and a 12 oz PET jar.
What I found most interesting about this recipe is the body oil from Burt's Bees and the lemon zest to fragrance the scrub. According to Burt's Bees website, the oil that Martha recommends combines energizing Lemon Oil to refresh and Vitamin E and Sweet Almond Oil to soothe and moisturize, leaving you with soft, supple, beautiful skin, naturally. As I looked further down the page I found the following ingredients in the oil: prunus amygdalus dulcis (sweet almond) oil, citrus medica limonum (lemon) oil, triticum vulgare (wheat) germ oil, tocopherol, rosmarinus officinalis (rosemary) leaf extract, glycine soja (soybean) oil, canola oil. I am sure if you want to use plain almond oil instead of this you surely can but you may to to add the vitamin E (tocopherol) to help with slowing down the rancity of the almond oil. If you want to add lemon essential oil to your almond oil you can do that too.
The second item is the lemon zest. Since this would be fresh, I would be most cautious that this may go moldy or make the recipe go back faster. So that is something to watch out for. If you like you can leave this ingredient out if you choose and add lemon essential oil in place of it.
