Science
Mechanism of Action
SODIUM EDTMP functions within the product formulation by acting as a powerful sequestrant. It dissociates in aqueous solutions to bind with metal ions, such as those found in water or released from other ingredients. By forming stable complexes with these ions, it neutralizes their catalytic activity, thereby preventing oxidation reactions, maintaining product clarity and color, and preserving the efficacy and stability of the overall formulation.

Stability
This ingredient, particularly in its sodium salt forms, demonstrates excellent chemical stability and high thermal tolerance, retaining its properties at temperatures up to 200°C. Its optimal performance spans a pH range from 6.0 to 10.5, with specific salt forms like pentasodium (EDTMP·Na5) favoring 6.0-8.0 and octasodium (EDTMPS) favoring 9.5-10.5.
Safety
Safety Profile
While a specific CIR Expert Panel review for SODIUM EDTMP or its various salt forms is currently noted as 'insufficient data,' manufacturers generally characterize it as innocuous, non-toxic, and non-polluting. Related chelating agents like EDTA and its salts have been deemed 'safe as used' in cosmetics. One form, PENTASODIUM ETHYLENEDIAMINE TETRAMETHYLENE PHOSPHONATE, is reported to be present in 0.01% of cosmetic formulations. General safety advice includes flushing with water upon eye or skin contact.
