This homemade bubble bath recipe is made without chemical soaps or sudsing agents. It is sudsy, simple to make, and requires few ingredients.
Once you've gathered the homemade bubble bath ingredients, all you have to do is pour and mix them together. The water and castile soap will mix well, but the glycerin may settle at the bottom of your container. That's normal! I was serious when I told you that this is easy.
To use your homemade bubble bath, first give your jar a gentle shake, just enough to mix in the glycerin. (Don't over-shake - it'll get foamy and too bubbly.) When it looks less separated, simply pour in 1 ounce of the liquid bubble bath into warm, running bath water. If you find that's not enough, keep adding in small amounts until you've reached your desired bubble level.
