Here is the exact bath bomb recipe to start with:
2 cups of Sodium Bicarbonate
1 Cup of Citric Acid
2-3 Teaspoons of Fragrance Oil (or 1-2 Teaspoons of Essential Oil)
2-3 Teaspoons of any Oil
1-2 Teaspoons of Polysorbate 80
1/2 Teaspoon of colorant
Binding agent - Water or Witch Hazel or Alcohol as needed (use a spray bottle)
- In a large bowl, mix the sodium bicarbonate, citric acid, and the colorant (all dry ingredients)
- In a shot glass, mix the fragrance, oil, and polysorbate 80
- Slowly pour the shot glass ingredients into the dry ingredients while mixing them together with the other hand. Once thoroughly mixed, begin to spray the mixture with the spray bottle. If you see it start to fizz, then just move the dry mix over the fizzing section and mix it in.
- Another method is to use a mixer. In this scenario, turn the mixer on a slower speed, and then drizzle the wet ingredients into the bowl. Mix and scrape the sides until the mix is completely mixed.
- Mix thoroughly until the consistency of the mix is the same. As they always say, put some in your hand, make a fist, and open it. If it stays in a solid shape, you are ready to go.
- Place the mix into your molds and press the mix in there firmly.
- If you are using a silicone mold, you can let them sit over night
- If you are using 2 plastic or metals pieces to form the bath bomb, you need to remove the bath bomb from both sides and let it sit on a towel or tray over night.
- Test them the next morning. They should be hard. You should be able to pick it up and drop it at least 12 inches and nothing happen. If it breaks, not enough wet ingredients. If you squeeze it in your hand and it breaks, not enough wet ingredients. And when I say wet ingredients, I mean the binding agents.
That's it. Store them in an air tight container. You can let them sit out if you want, but the natural humidity and moisture in the air causes the bath bomb to slowly react over time. This means it does not work as good and fizzes less.
