Palmitic acid is the most common saturated fatty acid found in animals, plants, and microorganisms. This acid has been used in skin care products as an emollient (this protects the skin) surfactant, emulsifier ( since it allows fats and suspended oils to be washed away) and a pacifying agent. This acid also helps to improve the texture of formations.

Stearic acid is also an emulsifier, emollient and lubricant that can soften skin and prevents products from separating in essence. It is a natural cleaning agent which helps to remove excess dirt etc.

4. Linoleic

Linoleum acid or Vitamin F provide moisture and plumpness to the skin. It also protects the skin’s barrier and is helpful in fending off UV rays and air pollutants.

Vitamin A boosts cell turnover in the skin and helps to speed up healing, prevents breakouts and it also supports the skin’s immune system and promotes natural moisturizing.

Myristic acid is commonly found in facial cleansers as well as in cosmetics that are used to preserve the skin’s moisture barrier.

8. Limonoids

Limonoids have health promoting as well as disease preventing properties. Studies have shown that they inhibit the proliferation of the cancer cells in the stomach, colon, breast, and even the skin.

There are many ways to extract andiroba oil. Some of which include: –

1. Extraction via boiling

The seeds are first shelled and boiled in water until they come apart. Sometimes salt is added to the process. As the seeds break, the oil will float to the surface of the water. Once the water cools the oil is skimmed off from the water’s surface.

2. Extraction by hand press

Andiroba Oil

Andiroba is first ground to the pulp. The pump is then pressed between two hard surfaces (this would remove the pulp moisture which contains the oil and water). The oil and water mixture is then collected because the oil will float to the surface.

3. Extraction via an expelled press

The expelled press machine is used to force the andiroba nuts through the open cavity. Inside the cavity the nuts are subject to friction and as well as pressure. As the cavity narrows only moisture can pass through (all of this happens because of the heat). The oil emerges from the expelled press and as a result, the dry parts of the nuts are left behind.

As previously mentioned, Andiroba is largely used in folk medicine. Uses include:-

  • As a mosquito repellent
  • For fevers
