Do you love bath salts but feel disappointed when they clump together or lose their scent over time?

The culprit, most likely, is the storage container. Bath salts are very sensitive to their environment. Moisture, direct sunlight, porous and not durable storage containers can all ruin your bath salts.

By the way if you want to find out more about bath salts, how to make them and what salts tend to sweat and clump up more than others when storing, check out this amazing bath salts guide.


How to store bath salts?

To make sure that your bath salts stay protected, clump-free and hold their scent, store your bath salts in a durable, air-tight container. The best bath salts storage containers are glass jars, PET plastic jars and quality cellophane bags.

Store your bath salts away from direct sunlight to avoid color fading. Ideally in a dry, cool environment.


These are the general bath salts storage guidelines, but there is more to learn. Did you know that the ingredients of your bath salts are important when choosing storage container?

The key ingredients to consider are essential oils or fragrance and baking soda.


Essential oils & fragrance

Most bath salts are scented, either with essential oils or fragrance. After all, aromatherapy is one of the applications of bath salts. Unfortunately, not every container is suitable for storing scented products. Most containers, even most simple plastic containers and bags, are too porous and will “leak” the scent. After a month of storage, your bath salts won’t have much scent left. 

On top of this, essential oils can damage and even melt some plastic containers and bags. That is why I suggest using glass jars, PET plastic jars and quality cellophane bags. 


Baking soda

You would probably never suspect that baking soda can be a problematic ingredient when it comes to storing bath salts. But it is. Baking soda can make your glass bath salts jars explode.

So what happens?

When baking soda reacts with citric acid and moisture, it releases gasses which can build up pressure in a container and cause it to explode. When you store your bath salts in an air-tight jar, they are in the dry form and usually cannot react. But if you store the jar in a bathroom, you run the risk of introducing moisture and that can start the reaction. As you can imagine, exploding glass jars are not only extremely messy but are dangerous too.

The explosive reaction may happen even if your bath salts do not contain citric acid because some of the essential oils can contain it. For this reason, I do not store bath salts with baking soda in glass containers.


Best container to store Epsom salts

Before going into storage for bath salts, I would first like to cover storing plain Epsom salts. Storing plain Epsom salts is a lot easier since they do not have other ingredients that often affect the storage choice.

The main thing to consider when storing plain Epsom salts is moisture. Epsom salts attract water from the air and will melt or clump together overtime if left open. So make sure you store them in an air-tight container. The material of the container is not important.

Best containers for storing bath salts

Now let’s talk in more detail about storing scented bath salts.

As I mentioned at the beginning of this post, there are 3 types of bath salts containers I recommenced: glass jars, PET jars and cellophane bags. Let’s have a look at these 3 options in more detail.


bath salts store in an airtight glass jars in a cupboard away from the sun

Storing bath salts in glass jars


Storing bath salts in glass jars is a very popular option. Here are some reasons why:

– Glass is not porous and will keep the scent from escaping

– Glass jars come in a variety of beautiful designs and shapes

– Easily available. Pretty much everyone has a glass jar at home that they can use to store their bath salts. If not, air-tight glass jars are available in most grocery stores.

It has, however, a couple of disadvantage to consider:

– You shouldn’t use glass containers for bath salts with baking soda as it may create an explosive reaction.

– If you drop a glass jar in your bathroom, you may damage the tiles and bathtub.

– Glass containers can be pricey.

When choosing a glass jar for your bath salts, make sure it is air-tight and that the cap is not made of porous material such as cork.

Storing bath salts in plastic jars

The best alternative to glass packaging is high density PET plastic. PET plastic containers are resistant to essential oils and can be used safely. They also won’t allow the scent to escape.

PET jars come in many sizes and shapes. The crystal clear jars are the most popular ones since they allow you to showcase your bath salts.

Here are some options for PET plastic jars:

Clear Plastic Jars

Clear PET Square Bottles


Storing bath salts in cellophane bags

Another option is to package bath salts in a good quality cellophane bags. Cellophane can do a good job of not letting essential oils and fragrance to fade if you pack your product well. It is also the cheapest option. The only challenge will be to wrap the baggies, so they would be as air-tight as possible.

When shopping for cellophane bags for bath salts, look for good quality, genuine cellophane bags. For example, the ones sold in dollar stores are not genuine cellophane.

    My dried flowers are starting to bleed into the salts. Is that normal? Also if I can only use the Mason jars right now, how do I keep it from building pressure, and clumping?
