“Where do I find citric acid?”
It’s probably one of the most asked questions here on The Makeup Dummy.
Citric acid powder has been a staple ingredient in all of my bath bomb recipes so far. It’s a key ingredient to get the fizzing experience bath bombs are known and loved for. Combine it with baking soda and a bath tub filled with water and you have a guaranteed fizz party in your bathroom.
So surely a bath bomb without citric acid powder must be impossible to make?
How To Make Bath Bombs WITHOUT Citric Acid Powder
As ‘scary’ or scientific as Citric acid might sound, it is actually a natural compound found in different food items. Like lemons! And that’s why this easy bath bomb recipe is made with a common and cheap household favorite: lemon juice.
This quick tutorial is perfect if you want to start making bath bombs RIGHT NOW and don’t have any citric acid lying around. I toooootally get it, trust me!
Watch the short video-tutorial I made here so you can easily follow along with each step. In case you’re wondering, the video can be watched without sound. So even in a noisy setting you can easily follow along.
Lemon juice does contain other natural components besides citric acid, like water. The citric acid you get from lemon juice is relatively small and diluted because of the water, but it’s there all right.
Even though these bath bombs won’t fizz as enthusiastically as their citric acid counterparts, they do the job. Drop one in your bath water to disperse the lovely smelling essential oils and release the skin soothing baking soda.
To make these bath bombs at home you only need a few common kitchen ingredients. Everything else is optional.
The base of this bath bomb recipe is very similar to that of a regular bath bomb tutorial. The fizzing reaction that occurs when you drop a bath bomb in your bath water is the result of baking soda reacting with the citric acid as they dissolve.
Since we’re not using pure citric acid powder in this tutorial, the base is simply: baking soda + lemon juice.
Ingredients You’ll Need
The full ingredient list for this tutorial is:
You can leave the coconut oil out of the recipe, as it will weigh the bath bomb down and create less fizz.
I recommend adding the coconut oil if you want to add essential oils as well, since the oil will help safely disperse the essential oils in the bath water.
Optional ingredients are:
- essential oils – Get it here
- decorations or coloring – I used dried lavender buds and cake sprinkles – Get it here
Essential oils are very powerful and should be used with caution. If you’re making this recipe with kids or want to give them as a gift, I recommend leaving the essential oils out.
Dried flowers, herbs or citrus zest are great alternatives to give your bath fizzies a natural scent!
Don’t forget: if you like this DIY than don’t forget to put a pin on it!
These bath bombs turned slightly yellow as they dried because of the lemon juice. If you don’t want this, you can choose your own color by adding a few drops of food or soap colorant to the mixture.

And the best part of this tutorial: the instructions for these bath bombs without citric acid powder could not have been easier.
- 1/2 cup baking soda
- 2 to 3 tablespoons lemon juice (see notes)
- 1/2 tablespoon coconut oil
- 6 - 12 drops essential oils
- decorations or colorants
- Medium mixing bowl
- Spray bottle
- Flexible cupcake molds
- Pour 1/2 cup of baking soda in your mixing bowl. Stir the powder with a spoon to break up any lumps.
- Optional: If you want you can add 1/2 tablespoon of coconut oil. This adds moisturizing properties to the bath bombs, but it will also weigh the bath bomb down and make it fizz less. You can use a different carrier oil, like olive oil or jojoba oil, but I like the fact that coconut oil doesn't affect the color of the bath bombs.
- Optional: This is also the best time to add a few drops of essential oils, if using. Stir the mixture well with your spoon after each drop. I highly recommend to also include coconut oil in your batch to help safely disperse the essential oils in your bath water.
- Pour the lemon juice into a spray bottle. Carefully spray the mixture while you keep stirring the batch between each spritz of lemon juice. You don’t want the mixture to start fizzing in the bowl! If you don't have a spraying bottle at hand, you can also add small amounts of lemon juice using a teaspoon to the batch. Keep stirring the mixture as you're adding the lemon juice.
- Don't be afraid to make the mixture wet. Check if the mixture clumps together by pushing it against the edge of your bowl with your spoon.
- Optional: If you want to spruce up your bath fizzies with decorations, you lightly sprinkle the bottom of each mold with your decorating item of choice. You can use cake sprinkles as they will also dissolve in your bath water. But for a more natural, fragrant approach I like to use dried flowers or dried citrus zest.
- Scoop 1 tablespoon of the mixture in each mold and press down firmly with the back of your spoon. Distribute the mixture evenly between your molds, pressing the mixture down as you go.
- Set the bath bombs aside and give them time to dry out. Mine took a full 2 days to harden completely. Pop them out of their molds once they’ve completely dried.
- Freshly squeezed lemon juice will work best. If you're using store-bought lemon juice, check the ingredient list to make sure it's pure juice and hasn't been diluted with water.
- The more lemon juice you use, the better they'll fizz. Just keep in mind that the more liquid you add, the longer it'll take for the bath bombs to dry.
- Alternatively, you can try this recipe with lime juice, orange juice or grapefruit juice. This will of course change the end result, and might affect the amount of fizz you get.
- These bath bombs without citric acid powder are best used 'fresh', so right after you make them. The longer you wait, the less they'll fizz.
