Butyrospermum Parkii (Shea Butter) Unsaponifiables Description
Butyrospermum parkii (shea butter) unsaponifiables is an emollient, antioxidant, and skin-soothing ingredient consisting of the fraction of shea butter oil that is not saponified during the refining process. Saponification is a process where alkaline ingredients are combined with glycerin and fats to create soap. Generally, unsaponifiable portions of butters and oils are not included in soaps because they have greater value in products meant to be left on skin.
The unsaponifiable compounds in shea butter include vitamin E (tocopherol), sterols, and potent antioxidant compounds research has shown have excellent soothing benefits. These qualities make Butyrospermum parkii (shea butter) unsaponifiables ideal for nurturing very dry or compromised skin and lips.
The typical usage level of this concentrated ingredient is between 1–5%; however, skin care brands may use more or less depending on the desired aesthetics and benefits of a given formula. As an example, this form of shea butter lends a smooth texture to products which enhances application.
This shea butter-derived ingredient is considered safe as used in cosmetics.
