Frequently Asked Questions
Why do bath bombs need citric acid?
Citric acid reacts with baking soda when wet, creating carbon dioxide bubbles that make the fizzing effect. This reaction is what makes bath bombs dissolve and fizz in water.
Can I use fresh lemon juice instead of citric acid?
No, fresh lemon juice will make your bath bomb mixture too wet and prevent proper molding. You need a dry powder form to maintain the correct consistency for bath bombs.
Will cream of tartar work as well as citric acid?
Yes, cream of tartar provides a similar fizzing reaction with baking soda. It's actually a great substitute and often easier to find in grocery stores.
How much citric acid substitute should I use?
Start with a 1:1 ratio for most powder substitutes. You may need to adjust based on the strength of your chosen substitute and test with small batches first.
Can I make bath bombs without any acid?
No, you need an acid to react with the baking soda to create the fizzing effect. Without an acid, you'll just have a solid block that dissolves slowly without fizzing.
