Suzan, I make and sell my own bath salts and body scrubs. They are extremely easy to make! Epsom salts and essential oil is the simplest way to make bath salt. Mix the two up in gallon sized ziplocs and the longer they sit, the more fragrance they'll have. And that's a most wonderful, unique idea for bridal shower favors!
2 cups non-fat milk powder 1/2-cup baking soda 1 tbsp. cornstarch 1/2 tsp. fragrance/essential oil (use more or less as desired)
Process first 3 ingredients in food processor or blender until powdery. Pour mixture into resealable plastic bag or container with tight fitting lid. Add fragrance oil. Shake well to distribute oil.
