Bath bombs have become incredibly popular lately, and many people have been asking about the use of cream of tartar in them. So, I’ve done some research to compare cream of tartar and cornstarch in bath bomb making to see which works better.
The main difference between these two ingredients is in how they affect the bath bomb’s performance. Cream of tartar helps create the fizzing effect that bath bombs are known for, whereas cornstarch doesn’t produce fizz but instead results in a thicker, gloppy texture in the water.
If you’re a DIY bath bomb fan, this is for you. I’ll break down the pros and cons of each ingredient, and even suggest some alternatives you can try.
The Science Behind How Cream of Tartar and Cornstarch Work
Cream of tartar can be used instead of citric acid to achieve the fizziness in bath bombs. It’s a fine powder that gives a smooth finish and helps the bath bombs harden. Because it’s less acidic, it produces a gentler fizz, resulting in a creamy, silky sensation in the bathwater. Cornstarch, on the other hand, delays how quickly the bath bomb dissolves by binding with the citric acid and baking soda. This can make the fizz last up to 4 minutes, rather than just a few seconds.
About Cream of Tartar
Also known as potassium bitartrate, cream of tartar is a byproduct of winemaking and often used in baking. It’s a fine, powdery substance made from the crystals left after wine ferments. It can be cream-colored, white, or brown depending on its acid content. In baked goods, it helps them rise and stay moist. In bath bombs, it adds to the fun experience by creating fizz.
Benefits of Cream of Tartar in Bath Bombs
1. Makes your skin feel softer by exfoliating dead cells.
2. Helps with household cleaning by loosening mineral deposits.
3. Lowers the pH of your bath bomb, making it fizz better.
4. Keeps bath bomb ingredients together, especially when using baking soda.
5. Soothes skin irritations like dryness, eczema, and psoriasis.
Should You Use Cream of Tartar in Bath Bombs?
Yes, you should. Cream of tartar can add fizz and foam to your bath bomb without any taste or flavor. It’s good for stabilizing the pH balance of water-based solutions in products like soaps and shampoos.
About Cornstarch
Cornstarch is a fine powder derived from corn and is often used in cooking as a thickener. It’s also useful in making homemade cosmetic products and other household items. Cornstarch is white, slightly sweet, and gluten-free, which makes it suitable for people sensitive to wheat products.
Benefits of Cornstarch in Bath Bombs
1. Easier to work with because it makes bombs more moldable.
2. Helps maintain the color and consistency of your bath bomb.
3. Keeps dry ingredients together, preventing them from crumbling.
Can You Substitute Cream of Tartar for Cornstarch in Bath Bombs?
Yes, you can use cream of tartar instead of cornstarch in bath bombs. Cream of tartar boosts the fizz and helps the bomb dissolve more quickly. It can also be used in other DIY projects like laundry detergent, shampoo, conditioner, or even homemade slime.
Final Thought
Both cream of tartar and cornstarch are great for making bath bombs, but they offer different benefits. Cream of tartar creates fizz and improves texture, while cornstarch helps with moldability and consistency. Try both to see which works best for you!
