In this article, we’ll answer all your questions about bath bomb expiration dates. We’ll tell you how long you can keep your bath bombs, how to tell if they’ve expired, and what happens if you use them after their expiration date. So if you’re wondering how long your bath bombs will last, read on!
What is a bath bomb and what are its ingredients?
A bath bomb is a small, round, typically fizzy ball that dissolves in water. They’re usually made with baking soda, citric acid, Epsom salt, essential oils, and food coloring. Bath bombs can also contain other ingredients like flower petals, glitter, or moisturizing agents.
When you drop a bath bomb into your tub, it starts to fizz and dissolve, releasing its color, fragrance, and other ingredients into the water. This can turn your ordinary bath into a relaxing, scented, and colorful sensory experience.
Primary Shelf Lives of Their Ingredients
A general rule is that bath bombs are best used with 12-months of production, but the fizziest bath bombs are always the freshest. Some of the ingredients in bath bombs include:
- Baking soda: When stored properly, baking soda can last approximately 18 months. So, if your bath bomb includes this ingredient, it likely has a similar expiration date.
- Citric acid: This ingredient can last up to two years when stored properly. During that time, citric acid can lose some of its potency, which may result in a less effective bath bomb.
- Epsom salt: When stored in a cool, dry place, Epsom salt can last indefinitely. So if your bath bomb contains this ingredient, it likely has a very long shelf life.
- Essential oils: These volatile oils can start to degrade after one year, so if your bath bomb includes essential oils, it will likely have a shorter shelf life.
- Food grade coloring: This ingredient does not affect the shelf life of a bath bomb.
- Other ingredients: Bath bombs can also contain other ingredients like flower petals, glitter, or moisturizing agents. These ingredients do not affect the shelf life of a bath bomb.
How to use a bath bomb?
Using a bath bomb is simple and only takes a few minutes. Here’s a step-by-step guide on how to use a bath bomb:
1. Fill your tub with warm water.
The warmer the water, the better the experience will be. If you have sensitive skin, make sure the water isn’t too hot. When filling your tub, make sure to leave enough room for you to comfortably sit in the tub.
2. Add a bath bomb to the water.
Gently place the bath bomb in the water. You can also put it on the edge of the tub and let it dissolve into the water.
3. Enjoy your bath!
Sit back, relax, and enjoy the show! The bath bomb will start to fizz and dissolve, releasing color and fragrance into the water. Some bath bombs also release flower petals or other surprises. At Spa-Da we tend to stay away from other additives that may leave a mess and residue behind.
4. Rinse off when you’re done.
When you’re done enjoying your bath, rinse off with clean water. This will help remove any residue from the bath bomb.
How long do unused bath bombs last?
Bath bombs are typically good for one year when stored properly. Unused bath bombs can last for a longer period of time if they’re stored in a cool, dark place. Bath bombs can also last for a shorter period of time if they’re not stored properly.
What happens when they expire?
When bath bombs expire, they can become less effective. The ingredients may not mix as well and the fragrance may not be as strong. expired bath bombs may also lose their color or start to crumble.
If you use an expired bath bomb, it’s unlikely that you’ll have any adverse reactions. However, if you have sensitive skin, you may want to avoid using expired bath bombs.
Can you freeze them or store them in the fridge?
You can store unused bath bombs in the fridge or freezer to extend their shelf life. However, freezing or refrigerating them may cause them to lose their color or fragrance. If you do choose to freeze or refrigerate your bath bombs, make sure to store them in an airtight container.
How to tell if a bath bomb has expired?
If you’re not sure whether a bath bomb has expired, there are a few ways to tell:
- The color has faded: If the bath bomb has lost its color, it may be expired. When bath bombs expire, the ingredients can start to break down and the color may fade.
- The scent has changed: During storage, bath bombs can absorb the scents of other items around them. If you notice that the scent of your bath bomb has changed, it may be expired.
- It’s crumbly: Since bath bombs are made with baking soda, they can become crumbly over time. If your bath bomb is crumbly, it’s likely expired.
- It doesn’t fizz: One of the most important things to look for when using a bath bomb is the fizzing action. If the bath bomb doesn’t fizz, it may be expired. Like we’ve previously said, the fizziest bath bombs are always fresh and right off the press.
Why do bath bombs often lose fizz over time if they aren't used?
Have you ever noticed that your bath bombs may lose their fizz over the period? It's not just your imagination-unused bath bombs do indeed lose their potency. There are a few reasons why this happens.
First, bath bombs are made with baking soda, which is a natural deodorizer. When exposed to air, the baking soda begins to break down, causing the fizz to dissipate. Additionally, the essential oils that give bath bombs their fragrance also evaporate over time.
Finally, moisture can also cause the fizz to disappear. If you live in a humid climate or store your bath bombs in a damp location, the moisture will cause the ingredients to break down more quickly.
To extend the life of your bath bombs, be sure to store them in a cool, dry place. In addition, using them within a few months of purchase will help ensure that you get the most fizz for your buck!
Can bath bombs grow mold or become rancid?
Bath bombs are a fun way to add some fizz and color to your bathtub, but you may be wondering if they can grow mold or become rancid over time. The good news is that bath bombs are fairly shelf-stable, and as long as you store them in a cool, dry place, they should last for well over a year.
However, there are a few things that can cause bath bombs to go bad. If they get wet, they can start to grow mold. And if they are exposed to too much heat or sunlight, the essential oils in the bomb can start to degrade, causing the scent to fade and the color to change.
So if you want your bath bombs to stay fresh, be sure to keep them stored in a cool, dark place. Furthermore, buy bath bombs that care about the shelf life, quality and fizziness of their bath bombs and shower bombs.
Tips for keeping your bath bombs fresh
Here are some tips for storing your bath bombs so they last longer:
- Store them in a cool, dark place — It's best to store bath bombs in a cool, dark place like a cupboard or drawer. When exposed to light or heat, bath bombs can deteriorate faster.
- Keep them in an airtight container — An airtight container will help keep your bath bombs fresh for longer. You can find airtight containers at most stores that sell kitchen supplies.
- Don’t store them near fragrant items — If you store your bath bombs near items with strong fragrances, the bath bombs may absorb the scent. This can cause them to lose their own fragrance.
- Check for expiration dates — Make sure to check the expiration date before using a bath bomb. If it’s expired, it may not be as effective.
- Follow the storage instructions on the package — Some bath bomb brands may have specific storage instructions. Make sure to follow these instructions to keep your bath bombs fresh for as long as possible.
- Use them within six months of opening — Once you open a package of bath bombs, it’s best to use them within six months. After this time, they may start to lose their fragrance or color.
- Discard them if they change color or smell different — If your bath bombs change color or smell different, it’s best to discard them. This could be a sign that they’ve expired or are no longer effective.
- Use them within two weeks of opening — Once you open a package of bath bombs, it’s best to use them within two weeks. After this time, they may start to lose their fragrance or color.
Bath bombs can last for a long time if they’re stored properly. However, once they’re opened, it’s best to use them within six months. If you notice that the bath bomb has changed color, scent, or texture, it’s likely expired and should be discarded.
Frequently Asked Questions about Bath Bombs
Why are my bath bombs not fizzing?
If your bath bomb is not fizzing, there are a few potential reasons. The most common reason is that the ingredients are not properly combined. When you mix the dry ingredients together, make sure to do so thoroughly so that there are no clumps. If there are clumps of baking soda or citric acid, the bath bomb will not fizz properly.
Another potential reason is that the bath bomb is too dense. This can happen if you use too much of one ingredient or not enough of another. The ideal density for a bath bomb is just barely firm enough to hold its shape when squeezed in your hand. (during the molding process)
Finally, make sure that you are using fresh ingredients. Baking soda and citric acid can lose their potency over time, so if your manufacturer has had their ingredients for a while, they may not work as well as they used to.
What makes bath bombs fizz?
They fizz because of a chemical reaction between the baking soda and citric acid. When these two ingredients are mixed together in the presence of water, they create carbon dioxide gas. This gas is what gives bath bombs their signature fizzing action. - Learn more by visiting our article, What’s The Science Behind A Bath Bomb?
How can I make my bath bombs fizz longer?
If you want your bath bomb to fizz for a longer period of time, there are a few things you can do. First of all, you need to make sure to use fresh ingredients. As mentioned above, baking soda and citric acid can lose their potency over time, so using fresh ingredients will help your bath bomb fizz for a longer period of time. Other ways to produce more fizz and foam is to add starches, cream of tartar, or surfactants such as SLSA.
Do bath bombs lose their fizz?
Bath bombs can lose their fizz over time, but this is typically not a problem if you use them within a few months of making them. If you want to extend the shelf life of your bath bombs, you can store them in an airtight container in a cool, dry place.
How long should a bath bomb fizz?
Ideally, a bath bomb should fizz for at least 1-3 minutes. However, the exact amount of time will depend on the size and density of the bath bomb, age and quality of raw materials, as well as the temperature of the water.
Do bath bombs work in cold water?
Bath bombs can work in cold water, but they will typically have a weaker fizz for a longer period of time than they would in hot water. This is because the chemical reaction that creates carbon dioxide gas is slower at lower temperatures.
What does Epsom salt do in bath bombs?
Epsom salt is often added to bath bombs for its therapeutic properties. Epsom salt is a type of magnesium sulfate, which is known to help relieve muscle pain, soften and exfoliate skin, and relax the body.
Do bath bombs work better in hot water?
Bath bombs typically work best in hot water, as the heat speeds up the chemical reaction that creates carbon dioxide gas. This allows the bath bomb to have a more intense fizz.
Should bath bombs float or sink?
Bath bombs can float or sink, depending on the ingredients used and the density of the mixture. Typically, bath bombs made with denser ingredients such as cornstarch or tapioca starch will sink, while those made with lighter ingredients such as baking soda will float.
