Add the bicarb soda, citric acid, epsom salts, cornflour, and french green clay to a medium bowl.
Stir with the whisk for 2-3 minutes until the dry ingredients are completely combined.
Pour the sweet almond oil, water, and essential oils into a small jar, and secure the lid. Shake the jar vigorously to combine the liquid ingredients.
Very slowly, one drip at a time, mix the wet mixture into the dry mixture, whisking as you go so not to activate the fizzing properties. Whisk until all the wet mixture has been added and the texture of the new mixture is all the same.
Carefully scoop the mixture into each half of the bath bomb mould, the press together and give a quick twist.
Allow the bath bombs to set for around 6 - 8 hours. Remove from moulds and store in an airtight container.
Notes
If you find that your bath bombs are coming out crumbly, you could try:
Mixing the dry ingredients with the wet ingredients carefully, until the wet ingredients are fully dispersed throughout the mixture.
If it is still not holding together properly, try adding a little more oil or water, just a drop at a time.
Make sure your mixture is packed tightly into the moulds to help hold everything together.
If your bombs are too wet, slowly add small equal amounts of baking soda and citric acid until you get the correct consistency.Make sure you add the wet ingredients very slowly as you don’t want the mixture to start fizzing just yet. The fizz needs to happen in the bath.If you want to give these lemongrass bath bombs as gifts, make sure that they have been cured at least overnight before wrapping to make sure that they are completely dry.Do you need a special mould? No, you can use a muffin tin or ice cube tray to create your bath bombs. They may be a different shape, but they will still work just fine. A silicon mould makes removing the moulds easier.Be careful when using essential oils. Make sure to do your research first and use with extreme care. Some essential oils are phototoxic, and can cause negative reactions on your skin in sunlight—such as burning, blistering, or discolouration.
