The Biochemical Composition of Shea Butter

Shea butter is a natural ingredient generally found in the composition of skin care products. Thanks to its biochemical composition, its use offers many virtues for the skin and hair. Discover what shea butter is made of.

Shea Butter, in Brief

Shea butter is a natural fat obtained from the fruit of the shea tree (Butyrospermum parkii), which belongs to the Sapotaceae family. This wild tree begins to produce fruit after 20 years and reaches its maximum production capacity after 50 years.

The fruit is harvested in the African bush exclusively by women between May and August. Once the fruit is brought home, the women process it in several steps to obtain the shea kernels: the fruit is stripped of its flesh, then the nuts are boiled, sun-dried and shelled. The kernels obtained are again dried in the sun before being transformed into butter.

Thus, "women's gold" is an additional source of income for millions of women in Burkina Faso.

The shea butter (INCI name: Butyrospermum Parkii Butter) in our care products comes from these fruits harvested in Burkina Faso. It is then refined in Europe using methods approved by organic certifications.  

In its raw state, shea butter is a solid butter with a waxy appearance. When exposed to room temperature, it melts and becomes oily in texture. Shea butter is light yellow to beige in color and has a slight odor of sweet almond.

Distribution of Fatty Acids (in %) in the Shea Butter Present in Our Products

Here are the main fatty acids present in shea butter.

  • 40 to 50 % of oleic acid or omega-9.

This monounsaturated fatty acid is a lipid that enters the composition of sebum, a substance naturally secreted by the body to alleviate the dryness of the skin and hair. It stimulates the production of sebum by the sebaceous glands. The vegetable oil of sweet almond is thus remoisturizing. It is recommended to treat dry and dehydrated skin and hair.

  • 36 to 50% stearic acid.

The National Library of Medicine (NLM) defines stearic acid as a long chain saturated fatty acid. The long chain is composed of 18 carbon atoms. In skin care, stearic acid is known for its emollient, nourishing and protective (film forming) properties.

  • 4 to 8% linoleic acid or omega-6.

This category of fatty acids is said to be essential because it is not synthesized by the body. Omega 6 contributes to the process of cellular renewal. In cutaneous application, they thus make it possible to fight against the signs of age and support cicatrization. They also soothe inflammatory reactions and are beneficial for sensitive skin, suffering from tightness and irritation.

  • 3 to 8% palmitic acid.

Saturated fatty acids, such as palmitic acid, have emollient properties, which means that they promote the hydration of skin and hair cells. They thus provide suppleness and softness.

The Unsaponifiable Part of Shea Butter

The unsaponifiable content is at least 4%. This remarkable content of unsaponifiable matter (tocopherols, phytosterols, triterpenes, keratin...) gives it great penetrating properties. It is a natural thickener for the oil phase.

  • Tocopherols are natural antioxidants known for their effect on cell oxidation. Thanks to its free radical scavenging properties, vitamin E protects the skin from environmental aggressions, such as UV rays and chemical pollution. Tocopherols are known to have anti-inflammatory properties and reduce premature aging of the skin.

  • Phytosterols and triterpenes (cinnamic acid, butyrospermol, lupeol, a- and B-amyrin) have UV protection properties, making shea butter a good ingredient to enhance the SPF of sunscreen products.

  • Sterols also have an anti-inflammatory effect by acting as free radical scavengers, as do tocopherols. They also improve the softness, hydration and the elasticity of the skin.

In Which Typology Care Products Is Shea Butter Found?

The 9-ingredient nourishing lip balm has been designed using only the ingredients essential to its function. Shea butter helps protect the lips from dryness.

Our nourishing face cream with hyaluronic acid also contains shea butter. Thanks to its content of hydrating and revitalizing ingredients, this product brings suppleness to the skin. Moreover, it decreases the feelings of tightness. It is adapted to skin with normal, mixed and dry textures.

You can also find this plant butter in the firming night mask based on prickly pear oil, an enveloping balm to nourish and regenerate weakened skin, and firm tissues.

The nourishing body cream also contains shea butter alongside squalane and plum oil to restore the skin's lipid barrier, reduce feelings of tightness and protect the skin from external aggressions.

Shea butter is also present in the stretch mark oil-gel with baobab oil to prevent and visibly reduce the appearance of stretch marks, while providing suppleness and elasticity to the skin.

Finally, our two 100% natural cold saponified solid cleansing products are enriched with shea butter.
