How we scored it
Where it comes from
Shea butter is obtained by pressing or solvent-extracting the kernels of the shea tree (Butyrospermum parkii). It is used as the crude or refined natural fat with no synthetic derivatization.
Shea butter is not synthesized industrially in the conventional chemical sense. Instead, it is extracted and purified from the shea nut. The process typically begins with the collection and drying of shea nuts. The outer shell is removed, and the inner kernel is often roasted to facilitate oil release and develop flavor. Following roasting, the kernels are ground into a paste. Traditionally, this paste is mixed with water and kneaded, causing the shea butter (fat) to separate from the aqueous phase and other solids. This crude butter is then washed, often multiple times, to remove impurities and residual water. Finally, the shea butter is typically heated to evaporate any remaining moisture and then cooled, often through a process of churning or pressing, to yield the final solid or semi-solid product. Modern industrial processes may involve mechanical pressing or solvent extraction (though less common for cosmetic grade due to purity concerns) followed by refining steps such as degumming, neutralization, bleaching, and deodorization to achieve desired purity, color, and odor profiles.
In plain English
Shea butter comes from the nuts of the shea tree, which grows in West and Central Africa. It's a natural fat that has been used for centuries in skincare and haircare. Think of it like a very rich, natural butter for your skin.
To get shea butter, people harvest the nuts from the trees. They then process these nuts to extract the fatty part, which is the shea butter. This process can involve roasting, grinding, and then separating the butter from other parts of the nut, often using water. After extraction, it's usually cleaned and sometimes refined to make it smoother and remove any impurities, ensuring it's perfect for use in cosmetic products.
CosIng definition: Butyrospermum Parkii Butter is the fat obtained from the fruit of the Shea Tree, Butyrospernum parkii, Sapotaceae
