There are varying qualities of cosmetic argan oil on the market, as evidenced by the wildly differing prices for oil sold on sites such as Amazon.com. There are several factors that are important in determining the quality of argan oil.
The argan nut is a hard almond-like seed, encased in an external shell and a fruity outside pulp. The nuts that are gathered for oil must have the exterior pulp intact. If there is no pulp, it means that the nut has been eaten and digested by a goat (goats love to eat the nuts) imparting a foul smell to the oil. Often, these "goat nuts" will be sold at a low price and then the oil will be deodorized, a process that destroys the essential nutrients in the oil. This is typically the case of the lower priced oils on the market.
The location from which the argan nuts are harvested also makes a difference. There are five distinct regions in the South of Morocco where the argan trees grow. The five regions engulf the coastland of Essaouira, to the desert of Taroudant and the mountains of the mid and anti atlas. Each of these areas differ in their soil, exposure and weather conditions. For example, the trees from Essaouira are exposed to more moisture than the trees of the desert region near Taroudant and so the nuts from Taroudant are smaller but more nutrient-rich. The area around Agadir includes lots of agriculture, thereby exposing the trees of that region to chemical pesticides and fertilizer, so the oil from that region is rarely organic.
Finally, the method of harvesting, extraction, and storage is extremely important. Nuts must be gathered from the ground, not the tree. The nuts that have not fallen yet from the tree are not sufficiently ripe. This also helps to protect the tree. The nuts are then dried for one week in the sun before de-pulping and cracking by hand. The highest quality oil is extracted by machine to eliminate excess water and the chance for bacterial contamination.
It is important to recognize that it is most often the women who do the hard work of extracting the argan oil who are undercut in the market for low-priced argan oil. It is crucial that these women receive a fair wage for their labor in order to make the money they need to survive.
Of course, Kahina Giving Beauty works with cooperatives that pay a fair wage to the women and ensures that only the highest quality nuts go into its oil.
