Pracaxi Oil: What should you know?

Pracaxi oil is derived from the seeds of the tree Pentaclethra macroloba (Fabaceae), a towering tree that can measure between 30 and 35 meters in height and is similar to a type of mimosa. It is primarily found in South America, particularly in Brazil and Guyana. Generally obtained through cold pressing to preserve all active ingredients, the extracted pracaxi oil exhibits a light yellow color and a characteristic odor that is reminiscent of peanuts.

Known by the Amazonian populations, thepracaxi oil has been used for centuries for its alleged benefits on stretch marks and scars. It is even used in traditional medicine in Brazil to help alleviate snake bites. Furthermore, it is also traditionally used for its properties on hair, particularly to facilitate detangling, discipline hair, or even define curls for curly hair.

Thepracaxi oil is particularly valued in cosmetics for the benefits it provides due to the richness of its composition in active ingredients.

In its pure form or as part of a blend, the pracaxi oil has numerous benefits for the skin. The pracaxi oil is also useful for application on the hair.

• Pracaxi oil, an oil with healing properties.

  Some studies have demonstrated the positive impact of the topical application of pracaxi oil on the visual appearance of scars. Indeed, its richness in oleic acid could influence the healing process, promoting tissue repair through the increase in the production of a metalloproteinase inhibitor, TIMP1. This inhibitor would act as an anti-inflammatory cytokine.

  Oleic acid also reportedly plays a role in the synthesis of type III collagen by fibroblasts, thereby facilitating the formation of granulation tissue. Moreover, it promotes cellular proliferation and influences the formation of new blood vessels, thus enhancing wound healing.

• Pracaxi oil for nourishing and hydrating the skin and hair.

  Pracaxi oil has a high content of essential fatty acids, which allows it toaid in strengthening the skin barrier. It contains linoleic acid, which can improve cell cohesion by integrating at the level of the horny layer. It also influences the synthesis of skin lipids, such as ceramides, which play a role in the construction of a fully functional skin barrier. Thus, fatty acids help to prevent skin dryness. Moreover, pracaxi oil is rich in oleic acid, a fatty acid naturally found in the composition of sebum. It works by limiting transepidermal water loss and creating a protective film on the skin's surface.

  The moisturizing and nourishing properties of pracaxi oil are also beneficial for hair. Indeed, the various fatty acids present in its composition also ensure the hydration of hair fibers, as well as their protection. They coat each fiber by creating a protective barrier on their surface. They also have the ability to penetrate between the scales of the cuticle, thereby strengthening theimpermeability of the hair fibers and their structure.

• Pracaxi oil for protecting skin and hair from the effects of oxidative stress.

  Pracaxi oil has a high concentration of antioxidants, particularly vitamin E and β-carotene. This composition allows it to act on the skin and hair by combating oxidative stress induced by free radicals, unstable species that are notably generated following exposure to the sun's UV rays.

  Oxidative stress can lead to several harmful effects on the skin, accelerating the appearance of visible signs of aging, but also on the hair by contributing to the deterioration of hair fibers or even their loss. Pracaxi oil used on the skin or hair could trap and neutralize free radicals through electron transfer. It would thus help protect the skin and hair from the devastating effects of oxidative stress.

• Pracaxi oil, a soothing oil for the skin and scalp.

  Pracaxi oil could be beneficial for soothing the skin and scalp by limiting irritations and associated symptoms, such as itching. Indeed, pracaxi oil is believed to have the ability toinhibit the synthesis of certain pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6).

  Through the oleic acid it contains, it could also promote the production of sirtuin-1 (SIRT1), an enzymatic protein that plays a role in preventing inflammation. The use of pracaxi oil on the skin and scalp could help soothe redness and irritation, and would be beneficial for dry and fragile skin and scalps, often subjected to feelings of tightness. It is recommended to apply pracaxi oil, diluted in a blend and not pure, to the scalp to avoid making it greasy.

• Pracaxi oil as a styling oil for textured hair.

  Beyond its hydrating, soothing, and antioxidant benefits, pracaxi oil is also known for its use in hair styling. Its richness in fatty acids makes hair more flexible and shiny, without weighing it down. By strengthening hair fibers, it allows for the reduction of frizz and facilitates styling. Finally, by ensuring the impermeability of hair fibers, pracaxi oil makes them shinier and softer. This vegetable oil is a good alternative for individuals with kinky, curly, or wavy hair to maintain their locks and keep them healthy.

Our nourishing hair oil enriched with pracaxi oil, piqui oil, and squalane helps to strengthen dry hair. It protects them from the harmful effects of oxidative stress, thereby restoring their shine and softness.

Thepracaxi oil is considered to be relatively safe for health. To date, no cases of intolerance, toxicity, or irritation have been reported following the topical application of this oil. Furthermore, its use is not contraindicated in pregnant or breastfeeding women, and in children. However, as a precaution, it is advised to perform a skin test on a small area of the body (inside of the elbow, inner wrist, or behind the ear) before extending its application to larger surfaces and observe potential skin reactions.

Furthermore, certain precautions should be taken with oily or acne-prone skin. Indeed, the data on the comedogenicity of pracaxi oil remains somewhat unclear at this time. Lastly, a point of caution should be noted regarding the quality of the oil: a rancid oil may potentially induce adverse effects when applied topically. The comedogenicity of the oil can also be altered due to a disruption in its quality.

Therefore, to maintain the optimal quality of the oil, it is necessary to store it properly in an airtight container, protected from heat, light, and oxygen, which can degrade it. Moreover, before each use, it is important to perform a quick sensory analysis to ensure that the oil has not turned rancid.
