Inositol Hexaphosphoric Acid IP6 Myo-Inositol Hexakisphosphate Phytate Rice Bran Extract
Compatibility
Works well with:
Niacinamide Vitamin C Alpha Arbutin Hyaluronic Acid Kojic Acid Glycerin
Use caution with:
High concentrations of divalent metal ions Calcium-based ingredients Magnesium-based ingredients
Phytic acid is a strong chelator and can bind divalent and trivalent metal ions (Ca2+, Mg2+, Fe2+, Zn2+), potentially destabilizing formulas that rely on these ions for structural integrity or efficacy. It can reduce the effectiveness of metal-ion-dependent preservative systems, so preservative efficacy testing is recommended. It pairs well with other brightening actives such as Vitamin C and alpha arbutin for synergistic melanogenesis inhibition.
Formulation notes
Phytic acid is a naturally derived chelating and brightening agent sourced primarily from rice bran, corn, and other cereal grains. It inhibits tyrosinase activity and chelates metal ions involved in melanin synthesis, making it a popular ingredient in skin-brightening and anti-hyperpigmentation formulations. At higher concentrations or lower pH values it can provide mild exfoliating activity; it is generally well-tolerated but should be used within its effective pH window for stability.
