Butyrospermum Parkii (Shea) Butter
What is Butyrospermum Parkii (Shea) Butter?
Butyrospermum Parkii (Shea) Butter derives from the fatty kernels of the shea tree (Vitellaria paradoxa), native to West and East Africa. The butter is obtained by cold-pressing or extracting the nuts from ripe shea fruits, yielding a semi-solid fat at room temperature that melts upon skin contact. Chemically, it comprises mainly triglycerides of stearic, oleic, and linoleic acids, alongside unsaponifiable fractions like triterpenes, sterols, and tocopherols. In cosmetics, it serves primarily as an occlusive and emollient agent, creating a protective film to reduce transepidermal water loss while softening rough textures. It also acts as a viscosity modifier in creams, lotions, and balms, enhancing spreadability and emulsion stability. Refined versions appear in lip products and body butters, while unrefined retain more bioactive compounds for targeted skin care formulations.
