Shea butter is a solid fatty oil that is derived from the nuts of Karite trees (also known as Mangifolia) growing in the semi-arid and savanna regions of west and central Asia. The Karite tree bears the fruits and the nuts inside the fruits contain shea butter. The nuts are then crushed, boiled and manipulated in order to extract a light colored fat, which is commonly referred to as shea butter. Pure shea butter resembles lumps of hard caramel ice cream. Being edible, shea butter is often used in food preparations, but it has gained huge popularity in the western world due to its widespread use in several beauty products such as lotions, cosmetics, shampoos, conditioners and many more.
What Is Shea Butter?
The main components of shea butter include oleic acid, stearic acid, linoleic acid and others. It gets absorbed quickly into the skin as it melts at body temperature. Shea butter may be refined or unrefined. Raw or unrefined shea butter is the purest form of shea butter which is most natural and least processed. Since it is extracted manually, it is able to retain its vitamins, minerals and other natural properties. Refined shea butter, on the other hand, is the processed form of butter.

- Fatty Acids: Shea butter basically comprises of five principal fatty acids namely palmitic, stearic, oleic, linoleic and arachidic acids with a higher proportion of stearic and oleic acids which together accounts for 85-90% of fatty acids. Stearic acid provides solid consistency, whereas oleic acid influences the hardness or softness of the shea butter.
- Phenolics: Phenolic compounds are known for their antioxidant properties. Shea butter contains 10 phenolic compounds – eight of which are catechins. Traditionally extracted shea butter has higher phenolic levels than that extracted with hexane. In fact, the catechin content of shea butter is higher than the total phenolic content of ripe olives. The overall concentration and relative percentage of shea kernels varies from region to region, depending upon the level of environmental stress endured by the trees.
