If you’re a regular here, you probably know that I’ve written about how to make baths salts before. Scented with lovely fragrances, these beauties turn a mundane soak into a luxury spa treatment just for you!
Since then I’ve gotten into all sorts of things, including bath bombs recipes! What struck me as interesting was how similar the ingredients were to my DIY bath salts. So I did a bit of thinking and it came to me – what about fizzing bath salts?!
It took me a few experiments to get these DIY bath salts to fizz properly. The first time I made them I hadn’t used enough baking soda, which meant the citric acid got a bit wet and slowly fizzled away in the jar I was storing them in.
What a disappointment that was! But with a few tweaks, I finally came up with the formula for long-lasting bath salts that fizz spectacularly in the bath!
These are super easy to make and are great fun in the bath. This is also a great opportunity to show your kids how to make bath salts the natural way, as the fizzing is just such fun in the bath. I told my young grandson that we were making a potion, just like in harry potter!
He was transfixed and we had such a fun afternoon. Bath time has been a breeze since then, too!
So let’s take a look at the different ingredients we’ll need to make DIY bath salts that fizz in the tub. Spoiler, they’re very similar to bath bombs.
Supplies for Fizzing DIY Bath Salts
- 56% Epsom Salts (Fine sea salt substitute)
- 33% Baking Soda
- 10% Citric Acid
- 1% Lemon and Coconut Fragrance Oils
- Half a teaspoon of Cornstarch
- A few drops of yellow Soap Dye
- Jar/Container to store, PET plastic or glass.
Notes on Ingredients
- You’ll notice I’ve given percentages here and not exact measurements, just so you can scale up or down depending on your packaging. Generally, I like to make this in batches of 300g. If you’re looking to do the same, you’ll need 167g Epsom salts, 100g baking soda, 30g citric acid and 3g total of your lemon and coconut fragrance oils combined.
- Using half a teaspoon of cornstarch should normally be enough for up to 300g of bath salts. While half a tsp might be a lot of 100g, it shouldn’t matter too much. Add another half teaspoon for each 300g (so if you’re making 900g of bath salts to gift or sell, you’ll want 1.5tsp of cornstarch with your fragrance oils). You can omit this ingredient altogether, but it does help to sustain the aroma of your fragrance oils. It also helps to carry the oil from whatever container you’ve used to measure your oil, into your mixing bowl.
- While I am using lemon and coconut fragrance oils in this recipe, you can substitute these for whatever you like. You can even use essential oils if you so wish. I make Lavender Lullaby baths salts all the time, using lavender essential oils and throwing in some whole lavender buds as well. If it’s winter I like to use spicy, Christmassy aromas such as Orange and Nutmeg or Apple and Cinnamon. The choice is all yours.
- Liquid soap dye is super easy to work with, which is why I recommend using it here. However, it can cause problems when you add the citric acid. If you add too much, you also risk dissolving too much of the salt and ending up with a hardened mass. If either of these becomes a problem for you, try substituting for powdered mica.
How To Make Bath Salts That Fizz
Step 1: Assemble your ingredients by measuring them into the correct quantities. This just makes everything so much easier as we continue.
Step 2: Mix your Epsom salts with the baking soda. Use a good-sized mixing bowl, preferably made of glass (although plastic is fine to use, make sure not to use it for anything food related again).
Step 3: Now it’s time to color our salts. Add a couple of drops of the soap dye and mix thoroughly with your hands. Keep adding the dye and mixing, a couple of drops at a time, until you achieve a desirable color.
Use your liquid soap dye sparingly and don’t forget to mix really well. Too much and the salts will dissolve, leaving you with a hardened mass. If you’re struggling to get a good, strong color, try substituting for powdered mica.
Step 4: Pour your fragrance oils into your cornstarch. I’ve used a mix of the two fragrance oils at a 1:1 ratio (1.5g lemon and 1.5g coconut), although you can use whatever ratio you like.
The cornstarch should keep your fragrances smelling strong for longer, although you can omit it if you so wish. Then, go ahead and add it to your dyed salts and baking soda.
Step 5: Add the citric acid. Start with a little, and if there is no reaction go ahead and add the rest. Mix thoroughly.
Step 6: Pour or scoop your salts into your chosen container. A nice glass jar looks great if you’re gifting or selling these, but keep in mind that glass can break and this can be a nightmare in the bathroom. You can get some nice plastic PET jars, or you can even use cellophane bags (although don’t use ordinary sandwich bags).
Basically, you don’t want to use anything that will absorb your fragrance and leave you will scentless granules of salt. You’ll also want to make sure you can get an airtight seal on your container. Salts tend to extract liquid from the air, and so eventually you’ll find your bath salts become a mushy mess after a while. Do your best to keep the lid on whenever you’re not using them.
So there we have it, 6 easy steps to making luxury DIY bath salts that fizz in the bath. Whether you want to make bath time a bit more fun for your little ones, or you’re just looking for a luxurious experience just for you. Everyone needs to pamper themselves. Go on, treat yourself!
I found this pretty easy to make once I managed to get the quantities of the ingredients right. I doubt very much you’ll find this difficult if you follow my steps properly. Like I’ve already said, it’s so easy your kids can have a go too! If you find that these are still not fizzing, check the quality of your citric acid. If it doesn’t fizz on its own when submerged in hot water, you might need to buy a fresh batch (preferably from a different supplier).
