Compatibility
Works well with:
Phenoxyethanol Ethylhexylglycerin Niacinamide Sodium Benzoate Glycerin Hyaluronic Acid
Use caution with:
High concentrations of divalent cations (Ca2+, Mg2+)
Sodium Phytate is a strong chelator and can sequester divalent metal ions such as calcium and magnesium, which may disrupt formulas that rely on those ions for structural integrity (e.g., certain crosslinked polymers or mineral-based systems). It functions as a preservative booster by chelating trace metals that would otherwise support microbial growth or oxidative degradation. It is generally well-tolerated alongside standard preservative systems such as phenoxyethanol and organic acid salts.
Formulation notes
Sodium Phytate is the sodium salt of phytic acid, a naturally derived chelating agent obtained primarily from rice bran or corn. It sequesters trace metal ions that catalyze oxidation and microbial proliferation, thereby extending product stability and enhancing preservative efficacy. It is considered a mild, skin-compatible ingredient and is often marketed as a natural alternative to EDTA, making it popular in clean-beauty and eco-certified formulations.
