Sanitary products generally don't have an expiration date! Explaining storage guidelines for each item

Most sanitary products, such as pads and tampons, do not have a clear expiration date like food or cosmetics.

However, there is no guarantee that it will last forever, and the manufacturer has set the following storage guidelines for unopened products:

These are only guidelines when the product is unopened and stored in a place away from direct sunlight, high temperatures and humidity.
Once opened, sanitary products should be used up as soon as possible for hygiene reasons.

Reusable menstrual cups and discs need to be sterilised by boiling after each use, and can be reused for several years if properly cared for.

For example, Murmo's menstrual cup does not have an expiration date before opening, but once you start using it and take proper care of it, it can last for several years .

Whatever sanitary product you use, ultimately it's your own decision.

In addition to checking the storage conditions, be sure to check for signs of deterioration and make sure the product is in a safe condition before using it.

How to properly store sanitary products

Sanitary products come into direct contact with delicate skin.
That's why it's important to store it properly and keep it in a hygienic condition so that it can always be used.
We will explain in detail.

Store in a box or drawer with a lid

Store your sanitary products in a box or drawer with a lid to keep them clean and out of the way of dust and insects .

Especially when storing in a wet area such as a bathroom or on a storage shelf near the bathroom, it is recommended to use a double-layered box or store it at a high position to avoid moisture and water splashes.

It has a neat and tidy appearance and can be easily taken out when you need to use it, so you can store it while keeping it clean on a daily basis.

Avoid high temperatures and humidity

When storing sanitary products, it is important to avoid storing them in hot and humid environments .
For example, places like under the sink or the back of the closet are more prone to trapping moisture and heat than you might imagine.

Storing napkins in such an environment can cause the absorbent material to absorb moisture from the air and the adhesive part of the napkin to dissolve, leading to deterioration in quality and mold.
Be especially careful during the summer and rainy season, as the temperature and humidity in storage areas tend to rise .

Take measures such as changing the storage location or placing desiccants or dehumidifying sheets in the storage case.

Avoid direct sunlight

Sanitary products should also be stored away from direct sunlight.
Prolonged exposure to sunlight can cause discolouration of the surface of pads and tampons.

Additionally, leaving sanitary products near a sunny window or in a car can lead to deterioration, such as a loss of adhesive tape performance and sticky packaging.

Store your sanitary products in a cool place away from direct sunlight.

Put it in a storage bag for carrying around

When carrying sanitary products, it is recommended to put them in a resealable bag or a special pouch .

If you put it directly in your bag, there is a risk that it will rub against your keys or other small items, causing the packaging to tear or become dirty.

Also, when carrying sanitary products with you, don't leave them in your pack for long periods of time; replace them regularly to keep them clean.

Three reasons why you should avoid using old sanitary products

Even if the sanitary product is unopened, there are cases where you should refrain from using it due to storage conditions or deterioration over time.

Here we will explain in detail three typical situations in which it is best not to use the product.
Know the clear criteria to help you make the right decisions.

1. Discoloration

If the surface or absorbent material of your sanitary product has become discolored, avoid using it.

The color change may be due to deterioration of the material or the accumulation of mold or dirt .
In particular, even if the product is unopened, if it has been exposed to high temperatures, humidity, or direct sunlight, oxidation may have progressed.
It is recommended to dispose of it immediately, as it may lead to a decrease in absorbency and irritation to the skin.

2. The package is damaged.

If the outer bag or individual packaging is torn or ripped, do not use it, even if it is unopened.

Sanitary products are designed to maintain their quality when unopened, and if the packaging is damaged, moisture, dust, bacteria, etc. from the air may have entered the product .

You should be especially careful with items whose packaging has become worn and torn while being carried around, or items that have been stored for a long period of time.

It is important not to make a self-diagnosis and think, "It's just a little torn..." and not to force yourself to use it.

3. There's a strange smell

Even if the sanitary product is unused, if it smells different from usual, avoid using it.
In particular, moldy or oily smells may indicate a decline in quality .

The manufacturer also warns against storing the product together with strong-smelling items.

If you notice even the slightest strange odor, we recommend that you stop using it and replace it with a new one for safety reasons.

How long can I use the sanitary products I have stocked for disaster preparedness?

When storing sanitary products in your disaster preparedness backpack or emergency evacuation bag, please refer to the storage guidelines for each product.

When unopened, napkins can be stored for approximately 3 years, and tampons for approximately 5 years.
However, even new products may deteriorate more quickly if exposed to high temperatures, humidity, or direct sunlight.

It is a good idea to check for any strange odors, discoloration, or damaged packaging about once a year.

Also, when stockpiling sanitary products, we recommend using the "rolling stock method," where you replace them with new ones.
By stockpiling your usual sanitary products and replacing them regularly, you can avoid waste and maintain hygiene.

Do sanitary items such as cloth napkins and absorbent shorts have expiration dates?

Sanitary items such as cloth pads and absorbent shorts do not have a clear expiration date like disposable pads and tampons.

However, it is important to know the approximate lifespan, taking into account deterioration of the material and hygiene conditions.

To ensure that cloth pads and absorbent shorts last a long time, it is important to take proper care of them and dry them thoroughly.
Consider keeping more sheets on hand to reduce the frequency with which you use each one.

summary

Sanitary products do not have a clear expiration date when unused.

However, quality may deteriorate if stored for a long period of time or in an inappropriate environment.

Aim for three years for pads and five years for tampons, but avoid using any that are discolored, have an odd odor, or have damaged packaging for hygiene reasons.

Additionally, because sanitary products come into direct contact with the skin, it is important to consider where they are stored and how they are carried, and to manage them hygienically.

By regularly checking your stockpiles and daily use sanitary products, you can rest assured that you will have them ready in case of an emergency.
