10 Effective Ways on How To Store Castor Oil

1. Store Cool:

Castor oil has a very low smoke point and has a shorter shelf life when cooking. Make sure to keep the bottle of castor oil cool and away from direct light.

2. Keep It Away From Heat:

Castor oil has a very low smoke point and goes rancid easily when used in cooking, so it’s best to store it away from heat and direct sunlight to keep it fresh and free of impurities.

3. Store Away From Food:

Castor oil is mostly used in cooking, storing it away from food items. In addition, the castor oil bottle should be stored separately to prevent any accidental mixing of the castor oil with the foodstuff.

4. Keep Away From Humidity:

Humidity can cause castor oil to become thick, viscous, and curdy. Hence store the bottle of castor oil away from places with high humidity or moisture.

5. Avoid Direct Sunlight:

Storing castor oil in a cool, dark place will help it last longer. Visible light and high humidity can shorten the castor oil’s shelf life, so avoid keeping the bottle in a sunny spot or a damp area.

Place With High Humidity or Moisture.

6. Avoid Keeping It Under Refrigerator:

Castor oil turns thick and viscous when kept under refrigeration or in places with high humidity. Hence, it is best to avoid storing castor oil in these conditions if you plan to use it as a cooking oil.

7. Avoid Near Heat:

Castor oil is best stored away from heat and direct sunlight, so make sure to store the bottle of castor oil away from near heat sources such as radiators or stoves, which can cause it to become thick and viscous.

8. Store In A Dry Place:

Avoid keeping castor oil in places with moisture and humidity, such as the bathroom, which is likely to get exposed to moisture and water vapor. Instead, keep it in a dry place with less or no humidity to extend the castor oil’s shelf life.

9. Keep Away From Water:

Avoid coming in direct contact with water as it can considerably reduce the shelf life of castor oil due to the emulsion it creates, which affects the viscosity and consistency of the castor oil, causing it to become thick and viscous. Hence keep away from water sources.

10. Keep Away From Kids:

Kids are curious creatures who like to explore their surroundings. For safety reasons, it’s important to keep the castor oil bottle out of reach of children. Store the castor oil bottle on a high shelf where adults can easily reach it, to avoid any accidents or injuries.

Some Tips and Suggestions

1. Castor oil is flammable, so don’t store near any fire/heat source like the stove or furnace.

2. If you have a space heater or fireplace, keep it at least 2 feet away from castor oil.

Keep It at Least 2 Feet Away

3. Castor oil should be stored in a cool, dark place. Direct sunlight can heat up the bottle and cause the oil to spoil faster.

4. Castor oil should be tightly capped after each use because exposure to air makes it spoil.

5. Keep your castor oil in its original container if possible and use an opaque container to reduce the chance of degradation from light exposure.

6. You should always do a patch test with new oils before using them on your skin, even if you’ve used them before, and know that they’re safe for you.

7. Store your castor oil at room temperature and avoid heat and direct sunlight as much as possible.

8. Make sure you always use a carrier oil with castor oil if you put it on your skin or ingest it orally because pure castor oil can sometimes irritate the skin and mucous membranes of the mouth and throat.

How Long Does Castor Oil Last

Although a bottle of castor oil can last in your cabinet for three years, it’s always better to buy a new one. There is no way of knowing how long the previous bottle was opened before it was purchased, so a new bottle will ensure that you’re getting the most out of the product.

Always Better to Buy a New Bottle

In addition, castor oil can begin to separate into layers or become rancid if it’s older than three years old, so it may not work as effectively as a new bottle would.

Frequently Asked Questions

Q: Why Does Castor Oil Have a Smell?

A: Castor oil has a very distinct smell. This is because it contains a phorbol molecule, and many of the symptoms associated with castor oil ingestion are caused by phorbol. The smell is the phorbol, and if castor oil has been stored long enough to oxidize (turn yellow), it will begin to smell worse than when it was fresh.

When an unrefined castor plant is processed for castor oil production, a by-product of that process is phorbol, which is then refined out of the castor oil. If done correctly, there should be no phorbol in castor oil sold for human use. However, if not done correctly (e.g., if storage conditions were suboptimal), the phorbol will begin to break down and make the castor oil smell worse.

Q: Can I Use Expired Castor Oil?

A: Castor oil doesn’t expire for a long time, so buying a new bottle is always better. The shelf life of castor oil is three years. This makes room for possible contamination that can happen during the storing process.

Please note that you shouldn’t use expired castor oil for medical purposes because it has lost its potency and efficacy. It’s always better to store castor oil in dark containers at room temperature or below. The storage area should contain fluctuating temperatures, humidity, and sunlight.


Castor oil is a natural product with many health and beauty benefits, but it must be stored properly to maintain its potency. If you follow these simple guidelines for how to store castor oil, you will ensure that your expensive purchase lasts as long as possible. However, castor oil is also very delicate and needs to be appropriately stored to maintain its potency and benefits.
