What is a Bath Bomb?

bath bombs, also known as bath fizzers, are dry ingredients that are designed to effervesce once in contact with warm water. Once it hits the water, it releases Essential Oils, scents, colors, and bubbles to elevate your bath experience.

Ingredients:

• Baking soda
• Citric acid
• Epsom salts
• Fragrance oils
• Colorants
• Surfactants

How does bath bomb works?

Bath bombs' primary ingredients are a weak acid and a bicarbonate base.These are unreactive when dry, but react vigorously when dissolved in water to produce their characteristic fizzing over a period of several minutes. This is an acid–base reaction that involves conversion of citric acid and sodium bicarbonate to monosodium citrate and carbon dioxide:

The other ingredients in bath bombs can vary considerably. However, most have scented ingredients as well as dye to impart a pleasant fragrance and color to bathwater. Lathering agents, such as sodium lauryl sulfate, are also often added to create bubble foams.

Before shipping them off,there are a few things you need to do to make sure your bath bombs arrive in one piece.Learn more below.

Bath bombs are made with baking soda and citric acid.When combined and introduced to water,you get the lovely fizzing reaction.However,this also makes them a bit tricky to store-if there is any moisture in the air,they can start fizzing too early.That makes them puff up or crumble,and they won't be as fun in the tub.

Preventing this starts during the bath bomb making process.We recommend using witch hazel to wet the bath bombs,as water makes them fizz and alcohol can dry them out.Use one hand to mix the powders and one hand to spritz witch hazel.When it feels like wet sand and hold its shape when squeezed,you can pack it tightly into molds.Learn more in the Bath Bomb Molding Tips article.

The next important step is letting the bath bombs fully dry overnight,or up to 24 hours.They need to be stored in a cool and dry place.If you live in a humid climate,we recommend running a fan over them or using a dehumidifier.

Once they're dry and hard,you can move onto wrapping.

Shrink wrapping

This method will keep your bath bombs protected from the elements.It's ideal for selling or shipping,as the extra layer helps protect them.
For this method,you need shrink wrap bands and a heat gun(you can find one at a home improvement store).Place the bath bomb in the shrink wrap band and cut off any excess.Then,set the heat gun on low and aim it at the wrap for 1-2 seconds at a time.It should be fully adhered all the way around.
If you don't have a heat gun,you can use a blow dryer.However,blow dryers don't get as hot,so they may not adhere the shrink wrap fully.The same goes for plastic wrap in place of shrink wrap-when it's heated up it actually stretches out instead of shrinking,so the seal won't be as tight.If you're planning on making a lot of bath bombs,a good heat gun and shrink wrap are worth the investment.

In addition to using shrink film, you can also use tinfoil, and we work with the top Aluminum Foil Containers Manufacturer. Wrap the bath bomb tightly in aluminum foil, ensuring it's fully covered, then twist or fold the top to seal and store in a cool, dry place to maintain freshness.

Plastic molds

Another option is our plastic bath bomb packaging.We designed these to be a mold and package in one,although you can use them how you see fit.
Once you pack in the mixture,put on the lid and then let them fully dry.The seals are airtight to protect your bath bombs.
However,if you live in an extremely humid climate,you may want to take a few extra precautionary steps.First,leave the bath bombs in the molds overnight so they hold their shape.Then you can take off the lid or remove the bath bomb completely and let it sit in a cool and dry room overnight again.This just ensures every last bit of moisture evaporates so they last longer.Lastly,pop them back into the molds and make sure the lid is fully closed.

Do Bath Bombs Expire?

Bath bombs have a shelf life of about one year. A bath bomb will last only as long as its composite ingredient with the least shelf life. It is true that a bath bomb has a scent as sweet as an air freshener, but if it does expire, it will start to its scents as well as its good looks and effect.

If your bath bomb starts to smell bad, break up or grow mold, it is a sign that it has expired, and you should learn to throw them out at this point.

How to use a Bath Bomb

1. Plug your bath tub.
2. Fill the bath with warm water (or whatever temperature you prefer).
3. Once the bath is full, get in the tub.
4. Add the bath bomb and watch it fizz and bubble!
5. Soak in the tub for 20 minutes, or longer, if you like.
6. After you’re done soaking, drain the water and use a cloth to wipe down the bathtub, if there is any dye or oil residue.
