“It was brought to America by Spanish settlers and is used in the more expensive skincare lines,” says Cindy. It's also used as a carrier oil for aromatherapy essential oils mainly because it never goes rancid.
Generally, it can last for about 2 to 5 years when stored properly in a cool, dark place and in a tightly sealed container. However, over time, it may lose some of its beneficial properties and effectiveness. Signs that jojoba oil may have gone bad include: Off smell: A rancid or unusual odor.
Jojoba oil is one of those oils that doesn't really go bad, it has a long shelf life of at least 5 years. The colour can vary from batch to batch and different brands. If it does not smell bad or rancid it is ok to use. If it has been sealed and stored properly it should be fine to use.

Jojoba is LIKELY SAFE for most people when applied to the skin. It can cause some side effects such as rash and allergic reactions. Jojoba is LIKELY UNSAFE for anyone when taken by mouth. Jojoba contains a chemical called erucic acid, which can cause serious side effects such as heart damage.
That's why nature built such powerful antioxidant properties into jojoba. Plant oils readily oxidise or go rancid but jojoba is not oil. Its molecules have a structure that resists rancidity.
Heat does not affect it. Unlike oils, it can stand up to heating and re-heating. Likewise, our jojoba does not require refrigeration. It will congeal at temperatures below 45 degrees Fahrenheit.
It'll have an off smell if it's gone bad. Unrefined oils, including extra-virgin olive oil, are trickier. According to Decker, they have aromas and flavors that can mask rancidity, so it's hard for nonexperts to know if they are rancid by smell alone. As such, Decker recommends tasting the oil.
Jojoba combats free radicals and is resistant to oxidation because of the natural presence of antioxidants on jojoba, as well as jojoba's molecular configuration.
Oil with a low melting point (eg canola) is mixed with jojoba to keep it liquid at cooler temperatures. The fact that your jojoba turns solid at 10°C is a sign that it is pure.
Yes, jojoba oil's skin-soothing, moisturizing properties make it suitable for use on both the face and body. Jojoba oil is generally well-tolerated by all skin types, with a low chance of irritation or allergic reaction.
Coconut oil can go bad due to several factors. Exposure to air, light, and temperature fluctuations can lead to oxidation, causing the oil to become rancid. Oxidation involves the breakdown of fatty acid chains within the oil, leading to the formation of unstable compounds known as free radicals.
Extensive studies on Jojoba oil showed a wide range of pharmacological applications, including antioxidant, anti-acne and antipsoriasis, anti-inflammatory, antifungal, antipyretic, analgesic, antimicrobial, and anti-hyperglycemia activities.
The most stable vegetable oils include jojoba (actually a liquid wax), meadowfoam, fractionated coconut, watermelon seed, moringa and high oleic sunflower oils.
100% Pure Cold Pressed Jojoba (sometimes called Virgin Jojoba Oil or Cold Pressed Golden Jojoba) is liquid at room temperature and is a clear golden colour.
Low shelf-life oils
A rancid oil is packed with skin-damaging free radicals and will smell 'off'.
In some people, especially those with skin conditions, jojoba oil can cause an allergic reaction. This may appear as an itchy rash, red skin, hives, eye irritation, and, in severe cases, the closing of your airway. If you have these symptoms, stop using the oil.
Jojoba oil will interact with plastic and should only be stored in glass.
Vij recommends using jojoba oil at night when it comes to your skin care routine.
Experts agree that eating rancid food or oils from time to time is probably not harmful, but they do suspect that regular consumption could contribute to the development of inflammatory diseases, cardiovascular illness and even certain cancers.
Be careful for cooking purposes
Once you skim the rancid olive oil off the rest and pitch it, pour the remainder into a clean, clear jar. Mix in some fresh olive oil, using three parts of the new olive oil to one part of the old. Mix them together slowly and the flavour and silkiness will begin to return.
One of the best features of jojoba oil is its shelf-life; because it's a wax ester rather than a fat-based oil it has a much longer shelf life and won't go rancid over time like other carrier oils.
Applying a facial oil like Jojoba should be done before you apply a moisturiser, but after cleansing, toning and applying a serum. You'll want to apply your skincare products lightest to heaviest, and because Jojoba has a heavier, oil-like consistency, it should be left toward the end of your routine.
Jojoba has a freezing point of 7 degrees Celsius, which is why in some colder climates our pure Wadi-Wadi Jojoba will solidify. Don't stress! This does not affect your Jojoba at all. Once it thaws it will be exactly the same as it was before.
