Common Name(s): Inositol hexaphosphate,ip6,phytate
CAS Number: 83-86-3
DESCRIPTION
What It Does: Provides multi-function brightening through copper chelation, antioxidant, and gentle exfoliant activity.
Why It's Used: Multi-function brightener โ phytic acid's six phosphate groups provide copper chelation for tyrosinase inhibition alongside direct antioxidant and gentle aha-like exfoliation in a natural grain-derived compound.
How It Works: Six phosphate groups provide multiple copper-chelating sites for tyrosinase active site copper removal. also chelates iron for antioxidant (fenton reaction inhibition). mild acidic ph provides gentle aha-like exfoliation. found naturally in rice bran, legumes.
Typically Found In: Natural brightening products,multi-function serums,rice-derived formulas

SCIENTIFIC NOTE
Phytic acid's hexaphosphate structure gives it six chelating sites for metal ions โ iron and copper are the primary targets. by chelating both copper (tyrosinase cofactor) and iron (fenton reaction catalyst), phytic acid simultaneously inhibits melanin synthesis and prevents oxidative damage โ a dual brightening + antioxidant mechanism from a single plant-derived molecule.
