How we scored it
Where it comes from
Mechanically or cold-pressed from the kernels of the argan tree (Argania spinosa), used in cosmetics largely as expressed. No commercially significant petrochemical alternative exists.
Argan oil is not synthesized industrially in the conventional sense of chemical reactions. Instead, it is extracted from the roasted or unroasted kernels of the Argan tree (Argania spinosa). The traditional method involves grinding the kernels into a paste, which is then mixed with water and kneaded to separate the oil from the solids. This process is often done manually by Berber women's cooperatives in Morocco.
Modern extraction methods may employ mechanical cold-pressing techniques to maximize oil yield and preserve the oil's beneficial properties. This involves crushing the kernels and then using screw presses or hydraulic presses to extract the oil. The temperature during pressing is kept low (typically below 50°C) to avoid damaging the delicate fatty acid profile and volatile compounds.
Following extraction, the crude Argan oil undergoes purification steps. These usually include filtration to remove solid particles and sediment. Depending on the desired grade and application, further refining steps like deodorization or bleaching might be employed, although for cosmetic use, minimal processing is preferred to retain its natural characteristics. The final product is a rich, viscous oil characterized by its high content of oleic and linoleic acids, tocopherols (Vitamin E), and polyphenols.
In plain English
Argan oil is a luxurious oil derived from the kernels of the Argan tree, which is primarily found in Morocco. Think of it as a natural treasure, carefully extracted from the seeds of this unique tree.
To get the oil, people traditionally grind the kernels into a paste, then mix it with water and knead it to release the precious oil. More modern methods use mechanical pressing, like squeezing the oil out with a press, to get more oil while keeping it as pure and beneficial as possible. This gentle process helps preserve all the good stuff inside, like healthy fats and vitamins.
After pressing, the oil is usually filtered to remove any bits of kernel. It's then ready to be used in skincare and haircare products, where it's loved for its ability to moisturize, protect, and condition.
