Equipment

  • Gloves
  • Digital Scales
  • Sieve
  • Mixing bowl
  • Small bowl to weigh ingredients in
  • Large bath bomb molds
  • A couple of spoons

Ingredients

  • 560 g sodium bicarbonate baking soda
  • 280 g citric acid
  • 40 g tapioca starch
  • 60 g Epsom salts
  • 100 g doTERRA fractionated coconut oil or, almond oil, apricot kernel oil, macadamia nut oil
  • 40 drops total doTERRA essential oils suggestions: AromaTouch / Lavender Peace / Citrus Bliss
  • 3 g bath-safe mica powder (about 1 scant teaspoon) or, freeze dried berry powders

Instructions

  • Start by weighing out then sifting all your dry ingredients together,
    excluding the colouring agent (baking soda, citric acid, tapioca starch, Epsom salts).
  • Weigh out your fractionated coconut oil, and add essential oils of your
    choice. Pour the oils over the dry ingredients, then us your hands (gloves on
    please!) to bring the mixture together, but don’t overwork it. You’re after
    something that resembles wet sand, holding its shape when pressed together.
  • Divide the mixture into two separate bowls, then add your colouring agent to either one or both.
  • Take half a bath bomb mold, add a small spoonful of one mixture, then gently pat it down, then a spoon of the other mixture, gently pat that down too, and so forth, until the mold is slightly rounded and over-filled.
  • Repeat with the other half, then bring them together, and press firmly. When you bring the halves together, they should be so full that it takes a little bit of a squeeze to get the halves to meet.
  • Tap the top half with the back of a spoon, then remove. Repeat on the other side.
  • Repeat until you’ve used the entire mixture up.
  • From here – you can either transfer to an airtight container and allow a full 24 hours to set, or, you can place them on a tray in the middle rack of the oven, set to low/warm (<50˚C/122˚F) for four hours.
  • Done! Add one bath bomb to your bath once filled.

Notes

  • If your bath bombs fall apart, It’s either due to the texture of your mixture or the technique of your filling. Firstly, the texture should feel like damp sand, and hold together when pressed. Secondly, a common mistake when filling is to pack the mixture in tight before you bring the two halves together. Don’t do that – fill it evenly, gently pat it down, then add some more. The over-filling is essential – and when you press the two halves together, it will compact nicely and come apart easily. Follow both these points and I can promise you no fail bath bombs galore!
  • If your bath bombs don't hold together when you pull them apart, they’re over-filled, and the mixture has been compacted too hard. Start again, and go a little easier.
  • If your bath bombs spread out like cookies in an oven once you've made them, it is because they have been exposed to water somewhere along the way, so have started to fizz.
  • You can use good old ice cube molds if you cant source bath bomb molds
  • Bath bombs need to be kept in an air tight container. They should last around 6 months.
