|Sodium Bicarbonate||35%||It is the reaction between sodium bicarbonate and citric acid that causes the bath bomb to fizz. This reaction needs water to get it going so avoiding water until you use the bath bomb is essential!|
|Citric Acid||35%||Citric acid plus sodium bicarbonate = carbon dioxide and water. This carbon dioxide is the gas that bubbles and fizzes. Don't worry, there isn't enough produced here to warm the planet.|
|Corn Starch||5%||Corn starch helps ensure the bath bombs float in the bath. This helps us see and hear the fizzing better and makes more of an impact than a bomb without the corn starch.|
|Surfactant 100% active||10%||It is important to use a surfactant that is 100% active. You could use a dry surfactant such as our Sodium Cocoyl Isethionate. That should be pre-ground in a coffee grinder then added. If you use a powdered surfactant you will need to use more oil to bind the bomb together. Otherwise use one of our polysorbates, the decaglyceryl monolaurate or the polyglyceryl-3-palmitate as the surfactant.|
|Vegetable Oil||4%||This is really there to help bind the powders together. Any vegetable oil can be used to help achieve that.|
|Kaolin||10%||The kaolin provides a surface for the aroma to cling and also makes the bath water feel soft on the skin. It is also gives a base for the colour agent to cling to and bulks up the bath bomb.|
|Perfume||0.5%||You can choose any perfume for this in theory but be mindful of who will use the product and how. Some essential oils are not suited to use in a bath situation. If in doubt please ask!|
|Colour Agent (water-free)||up to 0.5%||Your colour agent could be an Australian clay, iron oxides, micas or other powdered colour. Again this is a guide only, you may need to use less colour. Colours can also be blended to get different shades. Food colourings are not appropriate here as they are generally water based. The water ingredients in the colour will start the bath bomb fizzing.|
