This is a half-used detergent. The point of interest is not the cut-off section. Instead it is the white box at the bottom of the detergent sachet.

Does laundry detergent expire

Take a closer look, this is a close-up of the box. It has boldly written on it:

  • Manufacturing date: 04-2022
  • Expiry date: 04:2024

This proves beyond doubt that detergents do expire.

But the concept of expiration in detergents is different from expiration of consumables.

How do we mean, let’s add a little context.

Detergents are a cleansing agent, that helps to remove stains and  wash off bacteria and other microbes from laundry.

In aside from the visible cleaning of your clothes, they also serve as a disinfectant substitute.They don’t kill bacteria, but instead they make it possible to wash them off your hands or laundry.

When a detergent expires, it is unable to perform these varying tasks it normally does.

An expired detergent can still clean clothes. Depending on how long it had expired, it will still be able to produce suds.

However it becomes less effective at removing bacteria from clothes. 

An the it’s ability to produce lather reduces the longer it stays expired, therefore reducing it’s ability to clean efficiently.

Can you use a detergent after it expires?

Does laundry detergent expire

Yes you can. Expired detergent can still get your clothes clean.

However, it is not at optimal condition, hence you should experience less effectiveness after expiration.

This reduction in quality increases the longer it stays after expiration.

Some superficial qualities might begin to degrade noticeably. For example, 

  1. Scented detergents begins to loose its scent.
  1. The detergent begins to less effective at forming lather in water, especially cold or hard water.
  1. It’s surfactant properties gradually reduces, making it less effective at displacing dirt and stains.
  1. A long expired might begin to lose its physical properties, it might begin to look more like dust than grains. And it coagulates or stick together, this is caused by long shelf life, than the expiration in itself.

Other than this physical signs, an expired detergent can look like a good detergent in the eyes of a layman.

How long does it take from production to expiration?

Powder detergents last an average of 24 months, from production to expiration. After the 24 months, it starts to degrade gradually. But this is possible as long as it is in it’s sealed sachet.

The sachet is a major part of its preservation.

How long does an exposed powder detergent last?

Once it’s enclosing satchet is torn open, it becomes exposed to the element. Its preservation time begins to shorten.

There online sources suggesting that that an exposed powder detergent last just 6 months. This is not entirely true.

How long an exposed powder detergent lives before degradation depends on several factors:

  1. Humidity
  2. Heat
  3. Exposure to air

Unlike soaps, detergents are not biodegradable, that is they don’t breakdown and decompose easily  when exposed to the elements. 

So its main ingredients remain active even when exposed.

The major issue with exposed detergents is humidity.

Powder detergents are good water absorbent. And because more of these detergents are manufactured to easily absorb water and dissolv during wash.

When exposed, they can absorb moisture in the atmosphere, and becomes sticky.

For the record, a sticky powder detergent is still a functional detergent. So this does not automatically reduces it’s effectiveness.

As long as an exposed detergent is covered after use, it can last it’s full duration of 24 months.

Of course when it becomes sticky and form balls, it can be more difficult to dissolve in cold water. But this can be resolve by dissolving it in warm water before pouring it in your washing machine.

Also the time it takes a wash cycle to complete it enough to dissolve any sticky detergent.

This is true that in some cases, hardened detergent can stick to fabrics after wash, while this is true though, it is not a common experience. 

A thorough wash and rinse cycle should resolve this. Plus, dissolving detergent in hot or warm water is enough to break the most hardened coagulated powder detergent.

Does laundry detergent go bad in heat?

Detergent work best at room temperature.

How you define hot depends on your region.

In parts of African, temperature can go as range between 25 – 30 degrees celsius and it will not be considered “hot”, as long there is wind.

Many in colder regions might considered about 25 degrees celsius hot, but in this temperature detergents can do just fine.

However very hot temperature especially when accompanied by humid air, can cause detergent to become sticky and form solid moulds.

A sticky powder detergent is not a “bad” detergent.

Liquid detergent

As long as you endeavor to cover your power detergent after use you should be just fine.

Of course, very hot temperature can gradually degrade detergent. But only occur in really hot temperature like you’ll expect in a boiler room. This should even uncomfortable for a human. 

And even in this temperature, it will still take quite some time before noticeable signs are seen in the detergent. Except for very large amount of detergent, this will likely not occur before the detergent is used up.

If it is a sealed stored detergent, leaving it in a hot warehouse for very long period of time, might degrade, not just it’s cleaning pr, but also it’s market value. 

Other than this, your normal room temperatures, even on hot days will not degrade your detergent.

Does unopened laundry detergent expire?

Every detergent has an expiry date. On average most powder detergents, when sealed, have a 2-year expiry date, specified by their producers.

Liquid detergents, on the other hand, can last up to … if unopened.

However, note that detergents can still be used after their stated expiry dates. But then they gradually degrade with time, and loose some quality.

Can you use expired detergent in washing machine?

Does laundry detergent expire

Using an expired detergent does not harm your washing machine. 

However there is an open possibility of have detergent stains on laundered garments if the detergent is sticky and dried out, is applied in excess or enough water is not used during the rinse circle.

To prevent this, thorough shake a coagulated liquid expired detergent before using it in a washing machine.

A dried out powder detergent can be first dissolved in a warm or hot water, before applying it in a washing machine.

In any of, case, no harm done to the washing machine irrespective of whether the detergent is expired or not.

Conclusion

Most persons do not have to worry about detergent expiry dates. This is because the time from usage to expiration is larger than the time it takes to finish using the detergents.

The real concern is buy a detergent close to it’s expiry date.

Usually this date is boldly written on the container or sactchet. A brief look around the enclosing container will reveal the dates.

But if you are in possession of an expired detergent, there is no need to discard it. It will not damage your laundry.

You can use the remaining detergent left and ensure the next doesn’t expire before usage.
