Science
Mechanism of Action
This ingredient operates by forming stable complexes with polyvalent metal ions, such as calcium and iron, which are commonly found in water and raw materials. By binding these ions, it effectively neutralizes their ability to catalyze undesirable reactions, preventing issues like product degradation, oxidative rancidity, discoloration, and maintaining the full potency of active compounds.

The Formula
Formulation
Stability
Exhibits excellent hydrolytic and thermal stability, remaining robust across a wide range of pH values and at elevated temperatures. A 1% aqueous solution typically presents a pH in the range of 6.0–8.0. Photodegradation can occur in water at pH 3, 5-6, and 10, with shorter half-lives notably observed in the presence of iron ions.

Safety
Safety Profile
Generally regarded as safe for use within cosmetic products. However, the solid, concentrated form can be corrosive and may cause irritation to the skin, eyes, and respiratory system. Reports indicate potential for mild skin and eye irritation, suggesting patch testing is prudent, although adverse reactions are uncommon. Environment Canada classifies this ingredient as not expected to be potentially toxic or harmful.
