Dermofeel PA-3 is a natural chelating agent. Chelating agents bind metal ions, especially iron and copper, and destabilize microorganisms, thereby increasing preservative efficacy. Metal ions promote oxidation and discoloration and reduce foaming of soaps and detergents.
Dermofeel PA-3 has an acidic pH and may lower the pH of the final product.
Adding Dermofeel PA-3 at a concentration of 0.1% can increase the activity and effectiveness of Dermosoft 1388 preservative .
A natural chelating agent, Dermofeel PA-3 is readily biodegradable, unlike chelators such as EDTA .
