Science
Mechanism of Action
This ingredient operates as an anionic surfactant, effectively reducing the surface tension of liquids. This property facilitates the emulsification of oils and water, enabling the efficient removal of dirt, excess sebum, and impurities from the skin's surface. Concurrently, its composition contributes to skin nourishment, assisting in hydration maintenance and helping to mitigate dryness.

Safety
Safety Profile
The CIR Expert Panel has concluded that shea-derived ingredients, including its precursors, are safe for use in cosmetics when formulated to be non-sensitizing. While Sodium Shea Butterate itself was not explicitly listed in all assessments, it is a direct derivative. The EPA indicates that fatty acid salts, characteristic of soaps, have low acute oral, dermal, and inhalation toxicity, with a low propensity for dermal sensitization. Regulatory oversight for products primarily comprising alkali salts of fatty acids (soaps) typically falls under the CPSC. Butyrospermum Parkii (Shea) Oil, a source for this ingredient, is also recognized as GRAS by the FDA for direct food additive use.
