To determine if a carrier oil is bad, you should look for signs of oxidation, such as a rancid smell, discoloration, or a thick, viscous texture. It is also important to check the expiration date before using the oil, as it can go bad over time. If the oil has a strong, unpleasant smell, discoloration, or a thick texture, it may be best to discard it and purchase a new bottle.

Do carrier oils go rancid?

Yes, carrier oils can go rancid over time. This is especially true for oils that are not cold-pressed and those that are exposed to light and heat. To prevent your oils from going rancid, store them in a cool, dark place and use them within 6 months of opening. Additionally, it is important to check the label for expiration dates before using any oils.

Which carrier oils go rancid faster?

Carrier oils that are high in polyunsaturated fatty acids, such as sunflower oil and safflower oil, are more prone to rancidity. Other oils that are high in polyunsaturated fatty acids, such as hemp seed oil, walnut oil, and flaxseed oil, also tend to go rancid more quickly than oils that are low in polyunsaturated fatty acids, such as coconut oil, avocado oil, and olive oil. To prevent carrier oils from going rancid, it’s best to store them in a cool, dark place and keep them tightly sealed.
