Shea Nut Oil Overview
What Is Shea Nut Oil
Shea nut oil comes from the nuts of the shea tree, which grows wild in Africa. You find shea trees in regions where they mature over at least 20 years and produce about 20 kilograms of nuts each year. People use traditional methods to extract shea oil, such as de-pulping, boiling, drying, de-husking, and manual water extraction. Modern techniques include mechanical screw press expellers and solvent extraction, which help get more shea nut carrier oil from each nut.
Shea nut oil has a rich history. Ancient Egyptians used shea butter oil for skin protection and healing. Cleopatra’s reign saw shea butter as a prized ingredient for beauty and wellness. African women have relied on shea butter and shea nut carrier oil for centuries to moisturize and protect their skin and hair. Shea butter continues to help infants by reducing infection risk for umbilical wounds.
Shea nut oil production supports local communities. Women often lead the process, gaining economic opportunities and helping their families.

Nutrition
Fatty Acids
Shea nut oil contains a unique blend of fatty acids that help support your skin and overall health. You find four main fatty acids in shea nut oil: palmitic, stearic, oleic, and linoleic acids. Each fatty acid plays a different role in skin care and nutrition. Stearic acid helps create a smooth texture and protects your skin barrier. Oleic acid keeps your skin soft and helps lock in moisture. Linoleic acid supports skin repair and helps balance oil production. Palmitic acid adds stability to shea nut oil and helps your skin stay hydrated.
Here is a table showing the fatty acid profile of shea nut oil:
Fatty Acid | Percentage (%) |
|---|---|
Palmitic | 6.93 ± 1.68 |
Stearic | 38.83 ± 1.86 |
Oleic | 46.76 ± 0.82 |
Linoleic | 7.48 ± 0.35 |
You see that shea nut oil has a high amount of oleic and stearic acids. These fatty acids help nourish your skin and support your health. Populations that use shea nut oil in their diets benefit from its rich stearic acid (52%) and oleic acid (30%) content. These nutrients help provide energy and support heart health.
Vitamin E and Antioxidants
Shea nut oil contains vitamin E and other antioxidants that protect your skin and body from damage. Vitamin E, also called tocopherol, helps fight free radicals and keeps your skin looking healthy. Shea nut oil has both α-tocopherol and β-tocopherol, which work together to boost antioxidant activity.
Here is a table comparing the vitamin E content in different types of shea oil:
Type of Shea Oil | α-Tocopherol (mg/100 g) | β-Tocopherol (mg/100 g) | Total Tocopherols (mg/100 g) |
|---|---|---|---|
Crude Shea Butter | 8.52 ± 0.03 | 1.04 ± 0.02 | 10.06 ± 0.06 |
Refined Shea Stearin | 1.06 ± 0.03 | 0.21 ± 0.04 | 1.27 ± 0.07 |
Refined Shea Olein | 8.28 ± 0.03 | 0.97 ± 0.05 | 9.25 ± 0.02 |
Mixture | 4.58 ± 0.08 | 0.36 ± 0.03 | 4.94 ± 0.11 |
You get extra protection for your skin when you use shea nut oil with high tocopherol levels. Antioxidant compounds like catechins also help reduce inflammation and support your health.
