Raise your hand if you have the following questions:
- Does pepper spray expire?
- If a pepper spray expires, does it lose its sting?
- If it loses its sting, does it become ineffective for self-defense?
If your hand is raised, then we’re here with the answers! Keep reading to find out all you need to know about the duration of pepper spray and what steps you should take when using this life-saving tool.
Does Pepper Spray Expire?
Unfortunately, pepper spray isn’t like salt. It expires after a certain time and when it does, the product is no longer reliable.
How Long Does An Average Pepper Spray Last?
That depends on the product. The shelf life of a particular type or brand of pepper spray depends on its ingredients but typically ranges from two years to five years after manufacturing. This is why you must read the label carefully before buying one for yourself!
What Happens When a Pepper Spray Expires?
When a pepper spray expires, it may or may not become unusable depending on whether the bottle is still sealed.
If you’ve got hold of some old-stock (but still sealed) bottle which has passed its expiry date — don’t fret! You may not get as much out of this canister as expected, but there’s no need to worry about being harmed. The active ingredients will still be there, however, they may not work as well. In contrast, if your pepper spray has been opened and used before the expiration date, it’s best to replace it.
Will an Expired Pepper Spray Help You Defend Yourself?
Once again, the answer depends on whether the bottle is sealed. If it is, then it is likely to be effective enough for self-defense. But if the seal is opened and the product has expired, then you should get a new one because the chances of that product working are slim to none.
Why Does Pepper Spray Expire?
To answer this question, we have to first take a look at what makes up pepper spray.
What Pepper Spray is Made Of
Pepper spray is made up of Oleoresin Capsicum (OC) — an oily resin that’s extracted from chili peppers. This ingredient makes up the “sting” in pepper spray and, when it dries, it forms a film on the skin.
The expiration dates for pepper sprays are set to ensure that the OC remains potent enough to cause irritation. Once it starts to lose its potency, the manufacturer can’t guarantee that the product will be effective in causing discomfort or incapacitating someone.
Now that you know what pepper spray is made of, you’re ready to learn about how it expires.
Why Pepper Spray Expires
You’re probably thinking now that pepper spray expires when its OC loses its potency. While you’re right, you’re also wrong. You see, pepper spray does expire when its OC loses its potency. But the product becomes unusable long before the OC loses its potency because the pressure inside the bottle decreases much quicker.
When the pressure becomes too low, the bottle can no longer effectively eject out the pepper spray. That’s when a pepper spray expires — and the expiration date mentioned on products is based on the lifetime of their pressure.
