What Makes Bath Bombs Fizz

Bath Bombs And Bath Fizzies

Bath bombs are a compact mixture of various dry and wet ingredients molded to form different shapes. These days they have scents and essential oils in them, and they help make your bathing experience better and rejuvenate your body.

If there is eucalyptus or lemongrass in the bath bomb, it can even be good for the skin and act as a therapy for skin diseases, acne, sores, and rashes. They revitalize the whole body and provide the necessary moisturizing to the skin, thereby not letting it dry or rough.

Bath fizzies are nothing but a kind of bubble bath. The only difference is that bubble baths have bubbles atop the water, but bath fizzies have fizz inside them.

These bubbles are different from foam. The fizz is made from compounds and simple chemicals and is more effervescent than a bath bomb. When you plop a bath fizzy in the water, the bubbles will surround your body and tickle you. You get a very calming and relaxing experience.

Bath bombs are the most common type of bath fizzies. They are solid balls, mostly made of soda, cornstarch, Epsom salts, and essential oils.

They are everything one can expect them to be: aromatic, colorful, and bubbly. One of the essential qualities is being fizzy, which makes your bathing experience satisfying.

Apart from the fizz effect, the whirlwind of colors and pleasant fragrance make the bathing atmosphere tranquil and elevate your mood.

There are various bath bombs, including citrus bath bombs, lavender bath bombs, green tea bath bombs, cocoa butter bath bombs. Each has its use for the body.

What Ingredients Make Bath Bombs Fizz?

So, coming back to what makes bath bombs fizz. Most bath bombs use sodium bicarbonate and citric acid. These two are responsible for causing the ‘fizz.’

When you buy a bath bomb, it is dry. Hence, the ingredients don’t react with each other. However, when they contact water, the citric acid and sodium bicarbonate react.

As a result, sodium citrate and carbon dioxide get formed. The carbon dioxide, formed as a by-product, is the thing that bubbles and breaks the bomb up.

Carbon dioxide is the usual go-to compound for effervescence in chemistry, and you might have seen it used for soda drinks and other fizzy things.

Are Bath Bombs Supposed To Make Bubbles?

Bath bombs are often confused with bubble bath bars, but they are very different. Apart from the fact that bath bombs are very hard, almost like a porous rock, bubble bath bars are usually liquid.

The scientific difference lies in the way these two form their bubbles. The bubble bath produces mounds of bubbles on the top, somewhat similar to a foam layer.

On the other hand, bath bombs produce bubbles within the water to provide a relaxing sensation to the bather. The terminology here changes a bit!

The term bubbles are generally not used when it comes to bath bombs. Bath bombs fizz, and this fizz provides effervesce which tickles and soothes the body.

How Do I Get My Bath Bombs To Fizz More?

Here are some easy tips and hacks fo make your bath bombs fizz more:

Look for Isopropyl Alcohol

While buying a bath bomb, check for the ones which contain a higher portion of isopropyl alcohol as the primary liquid. If you don’t want your bath bombs to fizz prematurely, it needs to have isopropyl alcohol.

Get the ratios right

Ensure that you get the ratios and proportions right if you are trying to make these things yourself. The balance of citric acid to cornstarch and baking soda is the key to getting the fizz going.

Make Sure There’s Enough Citric Acid

In case your existing bath bomb doesn’t fizz and becomes a ‘bath dud’ while bathing, then change the recipe and try adding a bit more citric acid. Check if you’ve added more than the needed essential oils or colorant, which can sometimes mess up the process of fizzing. You can also try reducing the amount of cornstarch in the recipe or try removing it completely.

Keep them wrapped up!

Keep the bath bomb tightly wrapped in plastic until you use it. If it comes in contact with moisture, it loses its fizz big time. Make sure you store it in a safe and dry place.

Why Is My Bath Bomb Soft And Crumbly?

Bath bombs are supposed to be hard and ideally like a porous rock. If your bath bomb is too soft or cracks easily, then this might be happening because you got the ratios wrong in the mixture. Either the mix is too dry or too moist.

A dry mixture often leads to crumbly bath bombs. It can also make them less fizzy. Adding more witch hazel or a few more drops of essential oil may solve the problem as they will provide it with the necessary moisture.

If the mixture is too wet, it tends to expand a lot while being kept in the mold, leading to a crumbly bath bomb.

Will Bath Bombs Fizz Without Citric Acid?

Cream of tartar is an acid that is similar to lemon or vinegar. Its chemical composition includes potassium bitartrate, which is known to be citrus in nature.

Cornstarch
