Bath bombs are amazing, because they can make any bath extra special. When you drop them in your warm bath, they fizz, releasing nourishing body oil into your bath, and pleasant aroma into the air. Sure you can get bath bombs from Lush (for about $8 a pop), but you can also make your own (including bath bombs without citric acid) for a fraction of that price.
I’ve posted several easy DIY bath bomb recipes, including a simple recipe for oatmeal bath bombs (great for the most sensitive skin), and another recipe for DIY natural bath bombs. Both recipes use citric acid as an ingredient. But citric acid might not work for everyone, because some people are allergic to it. For them, exposure to citric acid could lead to rashy skin, or shortness of breath. So for people who are sensitive to citric acid, DIY bath bombs without citric acid might work better. This simple recipe for bath bombs without citric acid uses cream of tartar, also known as potassium bitartrate, instead of citric acid.
Cream of tartar is white and powdery. It’s an acidic byproduct formed during the winemaking process. People use cream of tartar to make meringue pies, meringue cookies, snickerdoodle cookies, and angel food cakes. Because it’s acidic (low pH level), cream of tartar is a good substitute for citric acid. So you can use cream of tartar to make bath bombs without citric acid.

Ingredients for DIY Bath Bombs without Citric Acid

- Baking Soda – 1/2 cup. Both Arm & Hammer Baking Soda and Bob’s Red Mill Baking Soda will work.
- Cream of Tartar – 1/4 cup. I use McCormick Cream of Tartar. You can also try McCormick Gourmet Collection Cream of Tartar.
- Arrowroot Powder – 1/4 cup. I use Bob’s Red Mill Arrowroot Starch / Flour. You can also use Starwest Botanicals Organic Arrowroot Powder, or Feel Good Organic Arrowroot Powder.
- Pink Himalayan Salt – 1/4 cup. You can try Spice Lab’s Coarse Himalayan Pink Salt. Sea Salt, or Epsom Salt will work as well. But if you don’t use Himalayan pink salt, your bath bombs without citric acid won’t have pink sparkles.
- Liquid Carried Oil – 2 tablespoons. I use rose petal infused sweet almond oil. You can use another carried oil, like coconut oil, grapeseed oil, sunflower oil, avocado oil, or jojoba oil.
- Bath Bomb Molds – I use Norpro meatball tong. You can also use bath bomb molds, or mini meatball tong.
How to Make DIY Bath Bombs without Citric Acid
(2) Add carried oil to the mixed dry ingredients. I use rose petal infused sweet almond oil, because I like to have rose petals in my bath bombs without citric acid. (Learn how to make herbal infused oil.) Another carried oil, like coconut oil, grapeseed oil, sunflower oil, avocado oil, or jojoba oil will also work.
To form the perfectly shaped bath bombs without citric acid, you have to pack the mixture into the tong or mold as tightly as possible. When using a meatball tong, I scoop up as much of the bath bomb mixture as I can. I then pack and press more bath bomb mixture through the hole on top of each half of the meatball tong.
(6) Finally, unmold the bath bombs without citric acid after about 30 seconds. To unmold, be sure the tap the tong or mold. The vibration from your tapping will release the your bath bombs without citric acid from the tong or mold.
(7) Let your bath bombs without citric acid dry for about a day. During this drying period, your bath bombs will harden, and become less likely to crumble and break.
That’s it! This is an easy recipe for bath bombs without citric acid that are great for people who are allergic and sensitive to citric acid. Cream of tartar is a good substitute for citric acid, but it’s not a perfect substitute. This is because the pH level of cream of tartar does not match that of citric acid.
What does that all mean? It means that bath bombs without citric acid (made with cream of tartar) do not pack the same level of fizz as those made with citric acid. Bath bombs without citric acid do fizz in a warm bath, but not for as long and not in the same level of intensity as bath bombs made with citric acid. Some people use lemon juice instead of citric acid, or cream of tartar. But bath bombs made with lemon juice have very little to no fizz. If you want to make bath bombs without citric acid, cream of tartar, rather than lemon juice, is definitely a better substitute for citric acid.
