How to make your own bath bombs

When you make your own bath bombs you can be 100% sure of what you’re putting on your skin. Certain shop bought products can be full of synthetic colours, fragrances and even glittery bits that will actually be doing you (and the environment) more harm than good. Some of the most common ‘synthetic’ ingredients in bath bombs are known endocrine disrupters and are linked to problems such as asthma, eczema, ADHD, cancer and other diseases, as well as urinary tract and vaginal infections. 

We've pulled together the basic ingredients and instructions for making your own homemade, ‘healthy’, fizzy bath bombs, however as you get more confident you can become more adventurous in your choice of ingredients - adding in other natural skin nurturing ingredients such as mineral rich salts, cosmetic butters, hydrolats, oats, dried flowers and even milk and honey! 

The two key ingredients are Sodium Bicarbonate (also called Bicarbonate of Soda) and Citric Acid. It is the chemical reaction between water and these two ingredients that creates  carbon dioxide, which causes the bath bomb to fizz and bubble. Sodium Bicarbonate should not be confused with Baking Powder as the latter has additional ingredients added.

Although they create the visual effect, Sodium Bicarbonate and Citric Acid don’t add any therapeutic benefit to your bath bomb, or your time in the tub! The real therapeutic benefits come from bathing in the water itself and from the essential oils and any additional skincare ingredients that you choose to add to your bath bomb mix.

Basic aromatherapy bath bomb ingredients

  • 300g of Sodium Bicarbonate
  • 150g of Citric Acid
  • 5-10ml of your favourite essential oils (we typically recommend using no more than 3 different oils per blend).
  • 5ml of your chosen carrier oil (e.g. Sweet Almond, Rosehip, Jojoba, Calendula - whatever takes your fancy)
  • Spray bottle with water (or hydrolat if you want to add some extra therapeutic properties)
  • Latex gloves
  • A bath bomb mould or something similar - a chocolate mould, muffin tray or even an ice cube tray will be fine. It's often easier to start off making smaller bath bombs as these are less likely to crumble. Once you've perfected the process then you can progress to larger moulds
  • Cosmetic colours / dyes - optional (choose natural colourings to stay kind to the skin).
  • Dried botanicals (i.e. lavender, rose petals) - optional 

Step by step instructions for making bath bombs

  • Pop on your gloves for protection as the citric acid will sting if it comes into contact broken skin. Measure out the Sodium Bicarbonate and Citric Acid and sieve into a metal or glass bowl. Mix thoroughly with your hands. Avoid getting the powder in your eyes or breathing it in, as it can be irritating.
  • Add in the essential oils and carrier oils. The oils generally don't cause fizzing, but some citrus essential oils can, so mix quickly if this happens.
  • If you're adding colour, add it in bit by bit until you have your desired shade. If you want to make multi-coloured bath bombs - separate your mixture into different bowls and add your different colours to each bowl. Mix the colours in quickly, rubbing the mixture between your finger tips - a bit like making a crumble topping!
  • Then spray in the water or hydrolat bit by bit, until the mixture starts to hold together when you squeeze it in your hands. Work as quickly as you can now, before the mixture starts to set.
  • Pack into your moulds, pressing down firmly. 
  • If you’re using a sphere-shaped mould slightly overfill each half then press together firmly (do not twist). Leave for a few minutes, then gently tap to remove one half of the mould. Leave the bath bomb to set in the other half of the mould for around 20 minutes.
  • Carefully take the bath bombs out of the moulds and pop them somewhere safe to dry out - ideally somewhere warm and dry.
  • Once dry, wrap them in cling film and continue to store in a dry place. Or, gift wrap them for friends and family. It's best to use them as quickly as possible as they will fizz more effectively when fresh. It's best to use them as quickly as possible as they will fizz more effectively when fresh. If they are left exposed to the air they will oxidize and won’t fizz.
