Want to make your own bath products but don’t know where to buy citric acid for bath bombs? This post explains everything you need to know about citric acid.
One of the most common questions I get asked since I’ve posted about homemade beauty products is where to buy citric acid for bath bombs. Unless you come from a family who cans their own food, citric acid sounds like something in a chemistry class and not an ingredient you want to bathe in.
Citric acid is actually a very common ingredient in bath products. Let’s explore what it is, it’s use in bath products, and where to buy citric acid for bath bombs.
But first, a warning
My stress levels were at an all-time high when I first came across the idea of bath bombs. I already use essential oils, so the idea of making these fizzy bath bombs that released a relaxing or energizing scent sounded like heaven!
I first made Peppermint bath bombs with the help of my two boys. It felt a little like a science experiment as we mixed the ingredients as the smell of peppermint filled my kitchen.
These bath bombs were meant for me and a few for homemade gifts, but the boys couldn’t wait to finish the day’s activity with a grand finale of bubbles and fizz in their evening bath. They got excited over choosing the bath bomb each night, dropping the bomb into a tub full of water and watching it foam until gone.
Fair warning, make enough for yourself and your kids or else they will disappear before you get to use them! Check out this tutorial on bath bombs for kids if you want to make them their own batch.

What Is Citric Acid?
Before we jump right into where to buy citric acid for bath bombs, let’s talk about what it is. The word acid might send up a red flag, but citric acid is a common food additive. It is a weak acid used to preserve food, add sour flavoring to foods, as an emulsifying agent, and even to descale hard water.
Some foods that you may find citric acid in are ice creams, soda, beer and wine, some cheeses, canned foods, baking goods, pre-packed fruits and veggies and even baby food.
Although citric acid is naturally derived from citrus fruit, today it is frequently derived from Aspergillus niger, a common form of black mold.
Is citric acid safe?
Citric acid is generally considered a harmless additive. It will have a similar effect on your skin to vinegar or lemon juice when used at full strength. The small amounts diluted in bath products shouldn’t cause a concern. Read the science behind it here.
Why do you need citric acid for bath bombs?
The short answer is you don’t need citric acid for bath bombs, but using it gives you a better fizz. Check out the science behind it all on this post from Scientific American about the chemical reactions in bath bombs.
If you aren’t concerned about the fizziness of your bath, see below for some citric acid alternatives.
Is there a citric acid powder substitute?
Try these substitutes if you don’t want to use citric acid or don’t have any on hand:
- Lemon juice
- Cream of tartar
Note these substitutes give you less (or sometimes no) fizz. If you don’t mind the lack of fizz, here is a tutorial on how to make shower steamers with cornstarch.
Where to buy citric acid for bath bombs – locally
You can buy citric acid in many local grocery stores, chain stores, or craft stores. Look for citric acid at Target, Walmart, or similar stores in the canning section. You will find citric acid at Michael’s or other craft stores in the soap-making section. When I shop locally, the most common brand I find is Ball citric acid in a 7.5-ounce container. Buying citric acid locally is convenient when you’re short on time, but you will normally find better prices buying in bulk online.
