2. Be careful with the type of moisturizers you use. The purpose of a homemade bath bomb is to dissolve completely when you add it to water. Add too much of a moisturizing oil can cause bath bombs to float or stick to the side of the bathtub. If you insist on using heavy moisturizes, be sure to use a solubilizer or dispersing agent to help get rid of any excess oil from floating on the top of your bath water. 3. Be aware of the two types of citric acid you can use. There are two citric acids that you can use for your homemade bath bombs: powdered or ground. The difference between these two types is that the powdered form can help give your bath bomb a smooth look and the ground citric acid will give your bath bomb a rougher look. Use either of the citric acids or an equal mix of both to achieve the ideal bath bomb shape.
