What it is
This ingredient is obtained from the press cake (seedcake) that remains after shea kernels are processed for their butter and oil. It carries residual polyphenols and other minor constituents from the shea kernel and is included in formulas to support a conditioned, comfortable skin feel. In sunscreens it typically appears at low levels as a botanical adjunct rather than as a primary emollient or UV filter.
Safety & warnings
Shea-derived materials are generally well tolerated and are widely used even in formulas marketed for sensitive skin. Botanical extracts can occasionally provoke sensitization in predisposed individuals, and people with known tree-nut or shea sensitivities should be aware of the source. It is used at low concentrations and is not considered a notable comedogenic ingredient.
Origin & sourcing
Natural; sourced from the seedcake byproduct of shea kernels (Butyrospermum parkii), a tree native to West and Central Africa.
