Bath bombs cost up to about £3 each in shops, with some premium brands costing even more.  Some commercial bath bombs have a dizzying array of ingredients, including preservatives, chemicals and other substances which can play havoc with sensitive skin.  Making your own is quite a simple process, plus you know exactly what is going into them.  The ingredients are actually quite simple and can be sourced quite cheaply from a chemist or online auction site.


What Ingredients Will I Need To Make Bath Bombs?

The main ingredients in bathbombs are baking soda and citric acid.  Some recipes use Epsom Salts (the main ingredient in bath salts), and others use corn flour as filler.  Fragrance is either essential oil or cosmetic grade fragrance oils and colourings is food colouring.  You will also need some sort of oil to help bind the ingredients.  Lastly, you will need some form of mould – these can be bought quite cheaply on Ebay (around £5 for a 5 cavity mould)

The Science Bit

The reaction which gives the bathbomb its characteristic fizz occurs when the baking soda and citric acid come into contact with water.  This forms bubbles of carbon dioxide.  Cornstarch if used helps the bombs to float.  Epson Salt is magnesium sulphate and is a regular ingredient in bath salts, due to its relaxing effect and the ability to soothe tired muscles.


Where Can I Find The Ingredients?

Any chemist shop will be able to supply citric acid it costs about 5 a kilo.  Baking soda is commonly known as bicarbonate of soda in the UK and this can also be bought at a chemists shop.  Online auction sites will also have the ingredients you need.  It will probably cost around £20 to set yourself up with moulds and your first set of ingredients but you can make loads of bath bombs with your initial investment.


The method for making bath bombs is the same regardless of the recipe.  Firstly mix together all the dry ingredients.  In a separate bowl mix together the wet ingredients.  Gradually add the wet ingredients to the dry.  Once fully combined, press into  moulds.
