The basics and most key ingredients for a bath bomb are bicarbonate of soda (baking soda) and citric acid. These two ingredients form the core structure and basic characteristics of a bath bomb. They are what reacts with the water to create the fizz a bath bomb is known for. Any ingredients on top of these two are purely for aesthetic and characteristic affect, from colours to salts, cornstarch for silkiness and sodium alginate for slime. There is a whole host of ingredients to create an incredible range of effects.
For our recipe will be using Sodium Lauryl Sulfoacetate Powder (SLSA) which adds amazing foaming properties to your bath bombs and is perfect when you want to add some extra life and character to your bath time.
What makes bath bombs stick together?
Moisture can be the making or failure of a bath bomb. Not enough moisture will cause your bath bombs to crumble and break apart, whilst too much moisture will start the reaction process of your bath bomb and small bumps will appear where it is starting to fizz. It is all about finding the perfect moisture and consistency that makes your bath bombs stick together.
Adding a small amount of moisture, whether this is water, witch hazel or comes from your ingredients, you want enough that softens your mixture to bind your ingredients. It turns your powdered mixture into a snowball like consistency, allowing your ingredients to blend and hold together. Then as they dry and harden they build strength and hold together perfectly.
What do bath bombs do for you?
A bath bomb can be beneficial for your skin, your mind and your day to day well being. So how can a small bundle of fizz provide so many benefits?

Each bath bomb is unique, they are a great way to nourish your skin, by holding ingredients that release valuable properties. A warm bath infused with salts, lavender, carrier oils and more does wonders for your skin. Helping to clean out your pores, remove dead skin cells and freshen up your complexity.
Bath bombs are also used for aromatherapy and to create a spa-like experience, far more than a way to get clean, they are the perfect way to enjoy some me time. This along with the properties from the variety of ingredients used, help cleanse your body, soothe your skin and invigorate your mind.
Do bath bombs make a mess?
Making bath bombs can be a messy process, but using a bath is quite the opposite! A bath bomb in many ways to designed to dissolve and fizz into the water and clean your skin but the more funky bath bombs can leave residue in your tub. For example, an activated charcoal bath bomb can leave a black ring around your bath tub, but with any bath bomb, once your bath has been drained, simply rinse and wipe around and it will wash away easily.
If you have a bath bomb containing floral petals, these will often float in the water and can clog the plug when you drain the water. But they can easily be scooped up and removed, similarly with salts, although most salts will dissolve with the bath bomb, some larger particles will sink to the bottom (you will feel these on your bum), again you can easily pick these out.
Due to the nature of a bath bomb, any mess that is made, crumbs etc can easily be wiped away with a cloth and warm water.

Step by Step Guide To Making Bath Bombs...
Firstly, wearing gloves weigh out all of your ingredients.
Add the bicarbonate of soda and the citric acid into the mixing bowl. Mix thoroughly until you have a consistent texture.
Next, add in your SLSA and mix well ensuring you get rid of any lumps. SLSA is a very fine powder so be careful when adding and mixing.
For this recipe, we are going to be creating a pink and white patterned bath bomb so you will need to separate about a third of your mixture into a smaller bowl and leave to one side.
Then with your large bowl add in your colour and mix thoroughly.
Before you start building your bath bombs you need to make sure the mixture has a snowball like consistency. From a distance spray your mixture with water and mix until you start to feel the consistency change.
Keep adding small sprays of water until your mixture starts to hold together on its own. Repeat with your white mixture.
Now you can start building your bath bombs. Sprinkle in small amounts of your colours into your mould until you are happy with your desired pattern. Remember the pink is your dominant colour so you will need to fill the middle with the pink.
Make sure you make one-half of your mould slightly higher than the other so when you combine them they slot together easier. Push your two halves together and wipe away any excess.
Next using a flat edge tool gently tap on the mould which will help loosen the bath bomb as you can see then repeat on the other side.
Leave the bath bomb to one side to dry then repeat until you have used all your mixture.
Make sure you leave your bath bombs to dry for at least 24hrs so they are nice and solid then they are ready to use!
