Leading up to Rosa’s beautiful Bath Bomb Party Rosa and I became bath bomb experts. We made our own bath bombs practising for her party day. With some trial and error we came up with the best bath bomb recipe for us. Full of lovely natural ingredients that relax, soothe and cleanse your skin, these are the perfect bath time treats.

Rosa’s Bath Bomb Recipe

1 C Baking Soda
½ C Citric Acid
½ C Epsom Salts
¾ C Cornstarch

Mix together in a large bowl.

In a small jug mix:
2 Tbsp Olive oil
4 tsp Water
A few drops of essential oil. We used lavender.
A few drops of food colouring if you wish.

Slowly add a few drops of the liquid at a time.
We used a little spray bottle to slowly mist the liquid on.
You need to mix a little at a time and quickly before it starts reacting with the baking soda and citric acid.

You may need slightly more or less of the liquid. You will just have to keep slowly stirring until you can squeeze some into a ball and it holds. We used metal bath bomb moulds but you could used lined muffin trays or ice cube trays. Dried herbs like lavender, rose petals, chamomile and mint can be crumbled through the bath bomb at the first mixing stage or you can scatter a little in the bottom of your mould to look pretty.
Push the mixture into your moulds firmly and leave to set overnight.


We love that our Bath Bombs are full of lovely natural ingredients that are beneficial for us.
Here is a little information on some of the ingredients:

Baking Soda: Baking Soda has many skin properties including being antibacterial, anti-fungal, antiseptic and anti-inflammatory. It may even help clean the bath when the kid’s have finished!

Citric acid: Citric acid is a natural ingredient used in bath bombs for it’s fizzing properties. When baking soda and citric acid are mixed and are then put in water, they undergo a chemical reaction. A little science experiment for the kid’s while they are in the bath.

Epsom Salts: My favourite Bath Bomb ingredient. Epsom salts has many beneficial properties that can soothe the body, mind, and soul. Some of the countless health benefits include relaxing the nervous system, curing skin problems, soothing back pain and aching limbs, easing muscle strain, healing cuts and drawing toxins from the body. Magnesium from the salts can also be absorbed through the skin which will benefit children’s sleep and muscles.

Cornstarch: Cornstarch is used in the bath bomb to bind the ingredients together and hold the scent of the essential oils. Cornstarch has skin benefits too. It soothes skin and makes the bath water silkier and softer.

We hope you have a go at making your own bath bombs. If you have any questions or comments you can email Rosa and I at [email protected]
