Easter Surprise Bath Bomb Recipe

Nothing says Easter like hatching eggs! As the white bath bomb slowly fizzes away, a bright spring yellow is revealed, colouring the water like a chick emerging from its shell.

Ingredients:

This diy bath bomb recipe makes 3 bath bombs.

Equipment:

Bath bomb mould
Large mixing bowl
Measuring jug
Weighing scales
Gloves
Spray bottle

Method:

1. Mix the dry ingredients together

Weigh the bicarbonate of soda, kaolin clay and SLSA.
Do not add the citric acid to this stage.
Mix these ingredients together until fully combined.
Pour ⅓ of the mixture into a separate container (this should weigh 85.5g) and the remaining ⅔ in the other container should weigh 171g.
Add the mica powder to the bigger mixture and mix well.
You should have one bowl with a small amount of white powder and one with a yellow powder.

2. Add the wet ingredients

Measure the apricot kernel oil, essential oils, polysorbate 80 and water.
Split the liquid mixture into ⅓ and ⅔ (one part should weigh 5.3g and the other part should weigh 10.7g)
Add each mixture to the dry ingredients with the small liquid mixture going into the white powder and the bigger liquid mixture going into the yellow powder.
Mix each bowl well, until the powder and liquid has fully combined.

3. Add the citric acid

Weigh out the citric and again, split this into ⅓ and ⅔ (the ⅓ should weigh 43.3g and the ⅔ should weigh 86.7g)
Add the citric acid to each bowl and mix well.

4. Test for moulding

Take a small amount of the mixture and squeeze it all together.
It should hold together well and be a similar texture to damp sand.
If the mixture is crumbling, you will need to add some more water (make sure not to add too much water as this may cause the citric acid to activate and make the bath bomb stick to the mould).
We would recommend adding the extra water with a spray bottle to make sure there isn't too much liquid added. Starting with 2 sprays and adding more if necessary.

5. Fill your moulds with the white mixture

Gently pat the mixture into the mould and press against the sides. But do not pack this too tightly, this can cause the bath bomb to sink.
Make sure to keep the centre of the mould empty as this is where the yellow mixture is going.
Repeat this in the other half of the mould.

6. Fill your moulds with the yellow mixture

Each half of the mould should be filled so the mixture is just above the top of the mould.
Press the two halves together and leave to set for 30 minutes.

7. Unmould the bath bombs

Unmoulding the bath bombs can be a bit difficult the first few times.
Lightly tap the mould with a spoon and try to gently remove one half of the mould.
Once you have unmoulded half of the bath bomb, leave this to dry for around an hour.
After it has dried, turn the bath bomb and lightly tap the other half of the mould. Gently remove the mould and leave to dry again.
If your bath bomb has stuck to part of the mould, this may mean there was too much water in the mixture or the citric acid has started to activate in the mould.

How To Customise This Bath Bomb

This recipe is so easy to customise with any colour of your choice! Whether you want a pink, blue, green or purple surprise, you can explore our wide range of mica powders to find your favourite colours!

If you want to change the fragrance, you can choose from our range of essential oils! You can add between 1% and 1.5% of essential oil to the bath bomb and no more! If you want to change the essential oil, you must check Category 9 in the IFRA document for that essential oil to find the usage rates. As long as the percentage on the document is more than 1.5%, then it is fine to use!
