Science
Mechanism of Action
As a zwitterionic surfactant, Oleamidopropyl Betaine functions by lowering the surface tension of liquids, enabling the stable mixing of immiscible substances like oils and water. This action is crucial for dissolving and washing away fat and soil particles from skin and hair. Furthermore, it can help mitigate potential irritation caused by highly ionic surfactants when used in combination, enhancing formula mildness.

Stability
This ingredient exhibits robust stability against salt, temperature fluctuations, and hard water. While it maintains good low-temperature stability across both acidic and alkaline conditions, solutions may experience a rapid increase in viscosity under strongly acidic environments.

- Reduces irritation from purely ionic surfactants when combined.
Safety
Safety Profile
The CIR Expert Panel deems Oleamidopropyl Betaine safe for cosmetic use provided it is formulated to be non-sensitizing. Concerns regarding irritation and sensitization are predominantly linked to impurities, specifically 3-dimethylaminopropylamine and oleamidopropyl dimethylamine, rather than the betaine itself. It is considered unsafe in leave-on products if not appropriately formulated to control these impurities.
