POTASSIUM EDTMP.

Insufficient Data CAS 34274-30-1 / CHELATING

POTASSIUM EDTMP is a water-soluble potassium salt that functions as a chelating agent in skincare formulations. It primarily sequesters metal ions, thereby enhancing product stability, preserving appearance, and preventing degradation of other ingredients.

Summary

chelating

Science

Mechanism of Action

As a chelating agent (also known as a sequestering or complexing agent), POTASSIUM EDTMP neutralizes metal ions present within a skincare formula. This action prevents these ions from inducing adverse effects such as discoloration, oxidation, or destabilization of the product matrix and active components.

Dusting Analysis

Not commonly dusted

POTASSIUM EDTMP serves as a formulation aid rather than an active ingredient with direct skin benefits; therefore, 'dusting' in the context of topical efficacy or irritation from high direct application concentrations is not applicable.

Stability

POTASSIUM EDTMP is a water-soluble potassium salt derived from Ethylene Diamine Tetra (Methylene Phosphonic Acid) (EDTMP). While the acid form (EDTMPA) has a pH of ≤2.0 (1% solution), as a salt, it readily dissolves in water. No specific optimal pH range for its stability within cosmetic formulations has been identified, though most skincare products are formulated within a pH range of 4.5 to 5.5 for optimal skin compatibility.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

No direct safety assessment by either the Cosmetic Ingredient Review (CIR) Expert Panel or the Scientific Committee on Consumer Safety (SCCS) has been conducted for POTASSIUM EDTMP. While some GHS hazard statements indicate potential skin and serious eye irritation for the acid form (EDTMP), specific dermal toxicity data for POTASSIUM EDTMP as a cosmetic ingredient are currently undetermined. Paula's Choice also rates this ingredient as 'Not rated,' highlighting a current lack of comprehensive safety data.

Our Assessment

Verdict

Insufficient Data

While POTASSIUM EDTMP is a valuable chelating agent for maintaining formulation stability and appearance, there is insufficient comprehensive data regarding its direct skin benefits, sensitization risk, and long-term safety profile in cosmetic applications to provide a definitive skin-centric verdict.
