Abstract
The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of 13 Butyrospermum parkii (shea)-derived ingredients,
which are most frequently reported to function in cosmetics as skin and hair conditioning agents. The Panel reviewed
the available data to determine the safety of these ingredients. Because final product formulations may contain multiple
botanicals, each containing similar constituents of concern, formulators are advised to be aware of these constituents and to
avoid reaching levels that may be hazardous to consumers. Industry should use good manufacturing practices to limit impurities
that could be present in botanical ingredients. The Panel concluded that these ingredients are safe in the present practices of use
and concentration when formulated to be non-sensitizing.

Introduction
The Butyrospermumparkii (shea)-derived ingredients detailed
in this report function mainly as skin and hair conditioning
agents in personal care products according to the International
Cosmetic Ingredient Dictionary andHandbook (Dictionary).1
This report assesses the safety of the following 13 Butyrospermum
parkii (shea)-derived ingredients:
Butyrospermum Parkii (Shea) Butter Hydrogenated Shea Butter
Butyrospermum Parkii (Shea) Butter
Extract
Hydrogenated Shea Oil
Butyrospermum Parkii (Shea) Butter
Unsaponifiables
Butyrospermum Parkii (Shea) Nut
Extract
Butyrospermum Parkii (Shea) Nut Shell
Powder
Butyrospermum Parkii (Shea) Oil
Butyrospermum Parkii (Shea) Seedcake
Extract
The Panel previously reviewed the safety of Butyrospermum
Parkii (Shea) Oil, Butyrospermum Parkii (Shea)
Hydrolyzed Shea Seedcake
Extract
Shea Butter Glyceride

Butter, Butyrospermum Parkii (Shea) Butter Unsaponifiables,
and Hydrogenated Shea Butter in the 2011 safety assessment
of plant-derived fatty acid oils and found these ingredients to
be safe as used in cosmetics.2 Because data from the previous
assessment may help to inform the safety of the ingredients
listed in this current assessment, the relevant information has
been summarized in this report.
Botanicals such as Butyrospermum parkii (shea)-derived
ingredients may contain hundreds of constituents, some of
which may have the potential to cause toxic effects. In this
assessment, the Panel is reviewing the potential toxicity of
