Here is the list of tools you need.

Large mixing bowl

Small mixing bowl (or glass measuring cup with a spout)

Measuring cups/spoons

Bath bomb molds (or muffin tin)

If gifting: Plastic molds you can give away or plastic used for shrink wrapping

Rubber gloves

Ingredients

1 cup baking soda

1/2 cup citric acid

1/2 cup Epsom salt

1/2 cup cornstarch

Powdered all-natural food coloring

2 1/2 tablespoons almond oil – or melted coconut oil

3/4 tablespoon water

12-15 drops essential oil

Bath bomb molds

Instructions


The process of making bath bombs is pretty straightforward and relatively easy. 

  1. Whisk together the cornstarch, Epsom salt, baking soda, citric, and food coloring. If you’re planning on selling it be sure not to use gel food coloring because some countries still don’t approve of that for cosmetic products.
  2. Now you need to combine the melted coconut oil, water together with the essential oil of choice. We use 12-15 drops of essential oil but in case you aim for a stronger scent you can add more, just make sure to not add too much as this may cause your bath bomb to expand later on.
  3. Now very slowly drizzle liquid ingredients into dry ingredients until they combine entirely. You should aim to have a consistency that is similar to dry, crumbly sand. If your mixture is too dry, the bath bomb will crack. On the other hand, if it’s too wet, your mixture will not stick together and even if it does the bath bomb will sink when used, which is a big turn-off. So it’s really important to find that right consistency.
  4. It’s time to carefully pack the bath bomb mixture into each side of your mold, give it a gentle push together and let them dry. You can leave your bath bombs to dry overnight which is fine, but in case you’re in a hurry there are ways to dry your bath bombs quickly and safely, many people use the oven to dry their bath bombs.
  5. Lastly, comes packaging and wrapping. The one thing to remember is to make sure to let your bath bomb dry long enough before you start wrappign them. Wrapping them too soon, might cause your bath bomb to fizz prematurely. Also, if you opt on air drying them, make sure to not leave them to dry where the humidity is more than 40%. This will cause your bath bombs to go flat
  6. You can label your bath bombs if you’re on planning on selling them and shipping them. A good tip is to use eco-friendly wrapping, which is loved by many customers. 

TIP: If you wish to make a bath bomb that fizzes longer, changing the ratio of critic acid and baking soda (which is 2:1) should do the trick. Making your bath bomb harder by lowering the moisture ratio or adding kaolin clay helps if you want your bath bomb to fizz longer. Also, some people like to use Glycerin in their bath bombs which is fine, but if you live in a humid environment, your bath bomb might start fizzing prematurely.
