How Long Does Linseed Oil Last? Does it Go Bad?

If you’ve ever thought about the shelf life of different food and cooking ingredients, such as linseed oil, then rest assured—you are not alone!

In fact, many home cooks ponder this very question: how long does linseed oil last?

Does it go bad eventually? If so, when should you replace your bottle of linseed oil? All fair questions that require an answer.

The truth is actually quite surprising; while there are certain factors that can affect its shelf life, some may be longer than you think.

Let’s take a look at how to store (and keep fresh) this nutritious ingredient for maximum flavor and nutrition.

What’s Linseed Oil?

Linseed oil is obtained from the seeds of the flax plant.

It has a wide range of uses, including as a dietary supplement, as an ingredient in paints and varnishes, and as a treatment for certain medical conditions.

The oil is rich in omega-3 fatty acids, which are thought to be beneficial for health.

In addition to being taken orally, linseed oil can also be applied to the skin or used as a massage oil.

There is some evidence to suggest that linseed oil may help improve joint function and reduce inflammation.

It is also sometimes used as a treatment for dry skin and eczema.

Linseed oil is generally considered safe when used in small amounts.

However, it can cause side effects such as diarrhea, nausea, and bloating.

It should also not be used by pregnant women or people who are taking blood thinners.

How to Store Linseed Oil?

Storing linseed oil properly is essential if you want to protect it from breaking down.

The key factor to storing linseed oil is keeping it away from light, heat and air.

You should generally try to store the oil in dark colored containers, such as a ceramic or a tin can, and then make sure the lid is tightly sealed; even small amounts of air or light can transform the oil into something that’s not suitable for use.

Keeping the bottle at room temperature will extend its shelf life considerably, so avoid leaving it in direct sunlight or extreme temperatures.

Additionally, be sure to shake your bottles before use as settling might occur over time and this will prevent any clumps forming in your linseed oil.

How Long Does Linseed Oil Last?

Linseed oil is a popular product used by many for its versatile properties.

Many may be wondering just how long this product can last if unopened, and the answer is surprisingly long.

Unopened linseed oil typically lasts around 4 years before deteriorating beyond use.

You should keep in mind, however, that opened containers of linseed oil often require more frequent replacement; it’s best to follow product specific guidelines as listed on your container.

Additionally, store your linseed oil in cool and dry places away from direct sunlight to prolong its life.

As you can see, with the right care and maintenance, you can rest easy knowing that your linseed oil will last a while.

Can You Freeze Linseed Oil?

Yes, you can freeze Linseed Oil.

However, it is not recommended as it can cause the oil to become cloudy and thick.

If you do choose to freeze your Linseed Oil, be sure to store it in an airtight container in the freezer for up to six months.

After thawing, the oil may not be as effective as it was before freezing, so keep that in mind when using it.

How To Tell If Linseed Oil is Bad?

Determining the freshness of linseed oil can be tricky and requires a few simple tests.

Begin by looking for any discoloration, irregular thickness, or sulfur-like odors, as these are possible signs that it has gone bad.

To verify this further, take a spoonful of oil and try to rub it between your fingers; if the result is sticky or gummy then it is definitely too old.

Additionally, check for foreign particles in the solution; if found, that also indicates spoilage.

If all else fails, you can also try a smell test – when inhaled through the nose, bad linseed oil will produce an unmistakable musty odor with chemical undertones.


All in all, linseed oil is a product with many benefits.

If you take proper care of it and store it away from light and heat, it can last for years without going bad.

We hope this article has helped you understand how to get the most out of your purchase.
