Science
Mechanism of Action
This ingredient functions as a chelating agent, forming stable complexes with metal ions like calcium and magnesium. By sequestering these ions, it prevents them from interacting with other cosmetic ingredients, thus maintaining product integrity and appearance. It also exhibits humectant and skin-conditioning properties.

Dusting Analysis
There is no specific data available regarding Ammonium Ferric Pentetate being commonly 'dusted' or used at sub-efficacious concentrations. Its primary function as a chelating agent suggests it is typically incorporated at functional levels for stability.
The Formula
Formulation
Stability
Highly stable as a chelated complex, performing effectively across a broad pH range of 4.0 to 9.0. It is particularly useful in rinse-off products to counteract hard water effects.
Conflicts
- Strong oxidizing agents
- Strong reducing agents
- High concentrations of certain electrolytes
Safety
Safety Profile
While not individually reviewed by CIR, related pentetates and iron salts are generally considered safe at typical cosmetic concentrations. It is listed in the EU CosIng database without specific restrictions.
