Babassu (Attalea speciosa) Seed Oil

Heritage and History

Babassu (also spelled babaçu or babasu) oil comes from the kernels of the babassu palm (Attalea speciosa, also known as Orbignya oleifera or Orbignya phalerata). The palm is native to Brazil, Bolivia and Suriname [1], and forms vast natural stands in the transition zone between the Amazon and the Cerrado in northern and northeastern Brazil.

Babassu is woven into daily life in these regions. Almost every part of the palm is used, from the fruit and its oil for cooking and soap to the leaves for thatch and baskets and the shells for charcoal. The oil has long been used at home to soften skin and condition hair.

The oil is closely tied to the quebradeiras de coco babaçu ("babassu coconut breakers"), women who for generations have supported their families by gathering fallen fruit and cracking the extremely hard nuts by hand to free the kernels. Today many are organized into cooperatives and associations that campaign for free access to babassu groves and for recognition of their sustainable, community-based work [2].

Cultivation and Regional Origins

The babassu palm grows 10 to 30 meters tall, with fronds that can exceed five meters in length. It begins bearing fruit at around eight years old and reaches peak productivity at around 15. Flowering takes place mostly between January and April, and the fruit ripens between August and December. The palm is a pioneer species that readily colonizes cleared land, and it is found in particular abundance in the Brazilian states of Maranhão, Piauí, Tocantins and Pará.

Babassu is gathered from wild and semi-wild palms rather than grown on plantations. Ripe fruits fall to the ground, where they are collected and split open to reach the oil-rich kernels, which are then pressed to release the oil.

Chemistry of Babassu Seed Oil

Babassu oil is a "lauric" oil, like coconut oil: it is made up mostly of saturated, medium-chain fatty acids. That gives it a light, non-greasy feel and an unusual property: it is semi-solid in a cool room but melts at about skin temperature, turning to a clear oil as soon as it touches the skin. Here are the key components of pure, unadulterated Babassu oil:

Lauric acid (C12:0, typically 40–52%): The dominant fatty acid, a medium-chain saturated fat that gives babassu its light, quickly absorbed feel. One laboratory analysis of babassu kernel oil measured lauric acid at about 56% [3].

Myristic acid (C14:0, typically 10–20%): Another saturated fatty acid that adds to the oil's smooth, powdery-soft finish.

Caprylic and capric acids (C8:0 and C10:0, typically 3–10% each): Shorter-chain fatty acids that contribute to the oil's light texture.

Palmitic acid (C16:0, typically 5–21%): A longer-chain saturated fatty acid that adds body.

Oleic acid (C18:1, typically 5–15%): The main unsaturated fatty acid in babassu oil, adding a touch of richness and slip [4].

Vitamin E and Plant Sterols: Babassu oil also contains small amounts of tocopherols (vitamin E) and plant sterols.

Fatty acid percentages are typical specification ranges for commercial Babassu seed oil; exact values vary from batch to batch.

Benefits for Skin and Hair

Babassu oil's light, melt-on-contact texture makes it a versatile choice for skin and hair:

For Skin:

Lightweight Moisture: Babassu oil melts into the skin and leaves it feeling soft and smooth without a heavy or greasy finish. It is often chosen as a lighter alternative to coconut oil.

Comfort for Dry, Rough Skin: It helps relieve the feeling of dryness and tightness, leaving skin looking calmer and more comfortable.

Smooth, Silky Finish: Its powdery-soft feel makes it a pleasant base for body oils and balms, including for lips, hands and elbows.

For Hair:

Softness and Conditioning: Babassu oil helps hair feel softer, smoother and more manageable, and is especially popular for dry or chemically treated hair.

Frizz and Shine: Smoothed over the lengths and ends, it helps tame flyaways and adds a natural shine without weighing hair down.

Scalp Comfort: Massaged into the scalp before washing, it helps relieve the feeling of dryness and tightness.

How It Works

Most of the published science on babassu comes from laboratory, animal or composition studies rather than studies on people's skin. Here is what that research found, and what it does and doesn't tell us.

Medium-Chain Fatty Acids and Hair: In a 2023 laboratory study on bleached hair, medium-chain fatty acids, including lauric acid, penetrated the hair better than longer-chain fatty acids and did more to reduce protein loss from the hair [5]. That study tested purified fatty acids, coconut oil and MCT oil rather than babassu oil itself, but babassu is one of the richest natural sources of lauric acid.

Calming Activity: In a study in mice, babassu oil and lauric acid applied to the ear reduced swelling caused by several irritants, and the effect was stronger when the oil was formulated as a microemulsion [6]. This was an animal study, so it shows biological activity rather than an effect on human skin. Babassu oil has also been studied in laboratory and animal wound models [7].

Moisture: Like other plant oils, Babassu oil forms a light film on the skin's surface that slows the loss of water from the outer layers of the skin, which is what leaves skin feeling softer and smoother after use.

Allergen Information

Food allergens: Babassu is not one of the nine major food allergens recognized by the U.S. Food and Drug Administration (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame) [8]. Although babassu oil is pressed from the kernels of a palm nut (Arecaceae), the FDA does not count palm nuts or coconut among the tree nuts it treats as major food allergens [8].

Fragrance allergens: Babassu seed oil is a fixed plant oil, not an essential oil, and does not appear on the European Union’s list of fragrance allergens that must be named on cosmetic labels [9].

Reported reactions: We have not found published reports of allergic skin reactions to babassu seed oil. That does not rule out a reaction in a particular person.

Patch test: As with any new skincare product, try a small amount on your inner arm and wait 24 hours before wider use. If you have a known allergy, ask your doctor before using a new product.

Conclusion

Babassu seed oil is a light, melt-on-contact oil with a deep cultural heritage in northern Brazil. Its lauric-acid-rich composition leaves skin feeling soft and smooth without heaviness and helps hair feel softer and more manageable, making it a versatile everyday oil for both skin and hair.
