Tools and materials bath bombs with eucalyptus

What do you need to make bath bombs with eucalyptus? I kept the list of eucalyptus bath bomb ingredients pretty short and only used natural ingredients. Colouring the bath bombs is optional. You can leave them plain and still enjoy the benefits of an aromatherapy bath bomb recipe.

baking soda and citric acid – Baking soda is the main ingredient, and citric acid is needed to activate the soda. Both materials combined create the fizzing reaction when they come in contact with water. A ratio of 2:1 will give you a great fizz.
Natrasorb Bath – I used Natrasorb Bath, a modified tapioca starch, as an emulsifier for the essential oil. This ingredient absorbs large amounts of liquids, which are released and dispersed once the bath starch reacts with water.
Isopropyl alcohol in a spritz bottle – Alcohol is needed to form the bath bombs. A neutral alcohol with high alcohol content does this job best, but if rubbing alcohol gives you headaches, use witch hazel instead.
green spirulina powder – Spirulina powder gives these DIY bath bombs a lovely green hue and is also very nourishing for the skin due to its high mineral and vitamin content. The product will give the water a light green tint and doesn’t stain the tub. If preferred, you can also use cosmetic mica to colour this easy bath bomb recipe.
eucalyptus essential oil – Did you know that over 600 varieties of eucalyptus trees exist? Unsurprisingly, different types of eucalyptus essential oils are available as well. You can learn more about the different types of this captivating oil below.
bath bomb molds – I shaped my bath bombs in round metal bath bomb moulds. These metallic moulds come in different sizes and are very sturdy.

How to make eucalyptus bath bombs

I know you are wondering how do you make eucalyptus bath bombs. This fizzy bath bomb recipe without cornstarch is based on my other no-fail bath bombs and comes together in just 20 minutes! Here are the easy steps for how to make bath bombs at home:

Mix the Natrasorb Bath and essential oil. Combine the Natrasorb Bath and eucalyptus essential oil in a medium mixing bowl and whisk well.
Add baking soda and citric acid. Sieve the baking soda and citric acid into the same mixing bowl and stir everything together.
Spritz with alcohol. Spritz with alcohol, a little at a time, and incorporate well before adding more. Break down any lumps.
Colour with spirulina. Optionally, divide bath bomb mixture equally between two bowls and tint one portion with a 1/4 to 1/2 tsp spirulina powder.
Fill the mould. Loosely overfill both parts of the mould with a generous amount of mixture, creating a big heap in the middle. Alternate between layers of white and green mixture. Then press the mould firmly together and brush away any excess.
Unmould the bath bombs. Gently tap the mould with a spoon and lift one half. Turn the bath bomb over and remove the other half. Place on a tray lined with bubble wrap.
Dry the bath bombs. Let dry for 24 to 48 hours. Then seal each bath bombs in plastic wrap/clingfilm and store in an airtight container.
How to use bath bombs. When you’re ready to take a eucalyptus bath, fill the bathtub with warm water and add one to two bath bombs.

Tips and tricks for the best DIY bath fizzies

Before getting started on your own eucalyptus bath bomb recipe, read the following tips to get the best homemade bath fizzies:

Add the alcohol gradually. If you spritz too much liquid at once, the ingredients will start to fizz and dissolve.
Rubbing alcohol is quite strong. Avoid inhaling it and work in a well-ventilated area.
The bath bomb mixture should have the look and consistency of damp sand and keep its shape when pressed together. It’s best to work with your hands to get a better feel of the texture.
Packing the bath bomb mixture tightly into each half of the mould makes it challenging to unmould the bath bomb and can cause the product to break in half. Instead, overfill the mould with mixture and then press together.
Handle the bath bombs carefully after unmoulding as they are soft and fragile at this point.

Are eucalyptus bath bombs kid friendly?

How do you make bath bombs kid friendly? The answer all depends on what kind of eucalyptus essential oil you’re using! Some eucalyptus essential oils are safe for kids, but some are not. I often use the essential oils from Plant Therapy for my bath bombs recipes, and they offer 4 different eucalyptus essential oils. Two of these essential oils are safe for children. Here is what you need to know:

Not suitable for kids:

Eucalyptus Globulus: Eucalyptus Globulus essential oil has a strong herbaceous scent with woodsy undertones. It’s the most common eucalyptus EO and well known to support breathing, relieve aching muscles and joints, and stimulate circulation.
Eucalyptus Radiata: Eucalyptus radiata essential oil has a strong, crisp aroma with hints of citrus and florals. The EO helps to breath easier and to clear the mind. Eucalyptus Radiata is considered milder than Eucalyptus Globulus as it has a softer scent.

Safe for kids:

Eucalyptus Dives: Eucalyptus Dives essential oil has a strong herbaceous scent with minty notes. This eucalyptus essential oil is useful to stop sniffles, clear up congestion and relax your body after a long day. The invigorating fragrance revitalises the senses and gives you a mental boost.
Lemon Eucalyptus: Lemon eucalyptus essential oil has a light, sweet lemony scent similar to citronella. It’s the mildest EO of the bunch and can help to support a healthy respiratory system.

If you want to make these bath bombs for kids, I recommend using eucalyptus dives or lemon eucalyptus. You can see how many drops eucalyptus essential oil you need in the DIY box below.

DIY eucalyptus bath bomb variations

Eucalyptus is a wonderful essential oil in its own right. The strong, herbaceous fragrance is very unique and reminds me of a mix of mint, pine with a touch of honey. If you want to experiment, don’t be afraid to try out other bath bomb scent combos. Here are some ideas with skin safe essential oils for bath bombs:

Peppermint eucalyptus bath bomb – Eucalyptus and peppermint essential oil are an amazing match and make for the ultimate sinus relief bath bomb recipe. The minty notes make these aromatherapy bath bombs even more revitalising.
Lavender eucalyptus bath bombs – Soothing lavender essential oil pairs surprisingly well with eucalyptus and will boost the relaxing effect. I recommend using Eucalyptus Radiata to not to overpower the lavender scent.
Lemon eucalyptus bath bombs – Combining eucalyptus and lemon essential oil gives the bath bombs are wonderful refreshing fragrance that spreads positivity and will lift your mood. If you’re feeling adventurous, try other essential oils from the citrus family such as orange or lime.
Cedarwood eucalyptus bath bombs – The rich, woodsy notes of cedarwood essential oil is wonderful for bath bombs for men. Cedarwood supports respiratory health and creates a calming atmosphere to unwind.

How to store DIY bath bombs with eucalyptus

Wrap this fizzy bath bomb recipe in plastic wrap/clingfilm and store in an airtight container. It’s important to keep the bath bombs as dry as possible as high humidity and moisture will dissolve bath bombs.

Shelf life

The shelf life for this luxury bath bombs recipe is one year plus. Eucalyptus is very long-lasting, but the scent may fade over time. You can remedy this by dropping a few drops fresh essential oil on the bath bombs before use.

Can I use arrowroot powder with green oxide instead of the spruilina powder if I still want to make this recipe?

Irena | Country Hill Cottage

Hi Vinicia! You can use arrowroot powder in place of Natrasorb Bath but I don't recommend green oxide in bath bombs. The oxide can reacts with the citric acid and baking soda and releases sulfurous compounds that smell quite unpleasant. Green mica would be a good alternative. I hope this helps and happy making!

Can you use tapioca starch in place of natrasorb?

Tuesday 29th of December 2020

Hi Ashley! You can do that but regular tapioca starch doesn't dissolve in water like natrasorb does.

Sara

Monday 20th of April 2020

I can’t seem to find natrasorb or tapioca starch for this recipe. I’ve never made bath bombs, but can I substitute these items for something else ?

Hi Sara! You can also use 1/2 cup / 2.3 oz regular cornstarch instead of Natrasorb. Since regular cornstarch won't emsufiy the ssential oils into the bath water, I would also add 1 tsp / 0.25 oz Polysorbate 80. Polysorbate 80 is a water-soluble emulsifier that helps to disperse the oils in the bath water instead of just pooling on top.

If you are new to bath bombs, try my Himalayan salt bath bomb recipe. It's made without Natrasorb Bath and very beginner friendly. You can use eucalyptus essential oil and green spirulina or mica to scent and colour the bath bombs.

Please let me know in case you have another question and happy crafting! xx
