Butyrospermum Parkii (Shea) Butter Extract
What is Butyrospermum Parkii (Shea) Butter Extract?
Butyrospermum Parkii (Shea) Butter Extract is derived from the nuts of the shea tree (Vitellaria paradoxa), processed to yield a concentrated extract rich in vitamins, fatty acids, and antioxidants. The '8' likely denotes a specific standardized potency or concentration level used in formulations. It serves as an emollient, providing hydration and protection to the skin barrier.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Moisturising
Improves skin hydration and comfort by combining water-binding (humectant) and barrier-supporting (emollient/occlusive) mechanisms to reduce dryness.
Refatting
Replenishes lipids removed during cleansing to improve mildness and reduce tightness, leaving skin or hair feeling less stripped after rinse-off use.
Skin protecting
Forms a barrier to protect skin from external irritants.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
