Sodium Phytate is the sodium salt of Phytic Acid, a saturated cyclic acid.  Phytic Acid is found abundantly in plant tissues, especially bran and seeds, where it acts as the principal storage form of phosphorus.

Sodium Phytate is an all-natural chelating agent that can be used as a replacement for disodium and tetrasodium EDTA in cosmetic products.  It will help to prevent undesirable metal-catalyzed reactions, thereby stabilizing cosmetic products.  It may help with discoloration and rancidity caused by metals present in formulations and works synergistically with other antioxidants.

Chelating agents are commonly added to cosmetic formulations to act as a preservative potentiator,  Micro organisms need trace metals for cell wall maintenance and survival.   Chelants bind with these metals, making them unavailable to bacteria, thereby weakening bacteria and allowing cosmetic preservatives to work more efficiently.  EDTA is commonly added to cosmetic formulations for this purpose and Sodium Phytate should have a similar function.

In addition to its chelating properties, Sodium Phytate has other skin benefits:

  • Moisturizes skin
  • Improves skin elasticity
  • Normalizes oily skin
  • May help reduce pore size
  • Helps lighten skin
  • May help improve the appearance  of cellulite

Sodium Phytate is fully neutralized and has a pH of ~12
