Science
Mechanism of Action
As an amphoteric surfactant, Stearamidopropylamine Oxide effectively lowers surface tension, facilitating cleansing and enhancing foam formation. Its molecular structure allows it to condition surfaces, providing a smooth feel and reducing static charge. Furthermore, it functions as an emulsifying agent, helping to homogenously disperse oil and water phases within a cosmetic product.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific safety assessment for Stearamidopropylamine Oxide. However, related compounds like Cocamidopropylamine Oxide have been deemed safe for rinse-off applications at concentrations up to 4%. Other related fatty acid amidopropyl dimethylamines were concluded to be safe in cosmetics when properly formulated to be non-sensitizing. The ingredient is not listed as a prohibited substance or color additive by the FDA.
