Cosphaderm® PA-12 (INCI: Sodium Phytate) is a 100% natural, corn brand derived chelating agent. Sourced from the “soak water” of corn bran—a classic example of upcycling and waste-valorization—it represents a powerful circular economy story. As the water-soluble salt of phytic acid, it is one of the most potent natural chelating structures known in plant biochemistry, offering a sustainable and high-performance alternative to synthetic EDTA.
Key Benefits and Performance
-
Multidentate Coordination: Its complex molecular structure allows it to “wrap around” and inactivate a broad range of divalent and trivalent metal ions (Fe2+/3+, Cu2+, Ca2+, and Zn2+).
-
Broad pH Stability: Unlike some synthetic chelators that lose efficacy in acidic or alkaline environments, Cosphaderm® PA-12 maintains high chelating power across a wide pH range, making it suitable for almost any formulation type.
-
Oxidation & Color Protection: By sequestering transition metals like Iron and Copper, it prevents the formation of Reactive Oxygen Species (ROS). This extends the shelf life of oxidation-sensitive oils, fragrances, and active ingredients while ensuring color consistency.
-
Enhanced Foaming: In rinse-off products, it prevents calcium and magnesium from interfering with surfactant performance, ensuring a rich, stable foam even in hard water areas.
-
Preservation Support: It indirectly aids preservation by depriving microorganisms of the trace minerals (like Iron) that are essential for their enzymatic function and metabolic growth.
Formulation Guidelines
-
Processing: Fully cold-processable. It should be added to the water phase at the beginning of the manufacturing process to ensure all potential metal ions in the process water are sequestered immediately.
-
Compatibility: * O/W Emulsions: Protects plant oils from rancidity.
-
Surfactant Systems: Maintains clarity and foam quality.
-
Water-free Systems: Can be used if a small amount of water or a polar glycol is present to facilitate dissolution.
