Bath melts are made of butters and oils that, when added to the bath,
melt and moisturize your skin.
Ingredients
one part cocoa butter
one part shea butter
one part sweet almond oil
Directions:
Melt the cocoa butter and shea butter in the microwave or in the top of a double boiler. Mix in the sweet almond oil. Pour into small (approximately one ounce) molds. Wait until it solidifies. You can put it in the freezer if you want it to solidify faster.
When you start your bath, put one bath melt in the tub. The hot water will melt it.
If you do not want to use the little molds, pour the entire amount into a larger container like a bowl, the bottom of a milk carton, or a coffee can. When you want some for your bath, scoop out the desired amount with your fingers.
