What it is
Sodium phytate is derived from phytic acid, a naturally occurring compound found in plant seeds and grains. In sunscreens and skincare it functions as a chelator, sequestering metal ions such as iron and copper that would otherwise catalyze oxidation and compromise product stability. By tying up these ions it supports color and odor stability and the performance of preservatives and antioxidants, and it is often used as a milder alternative to synthetic chelators.
Safety & warnings
Sodium phytate is used at low levels and is generally well tolerated, with no significant allergen or comedogenicity concerns in normal cosmetic use.
Origin & sourcing
Naturally derived; phytic acid is extracted from plant sources such as rice bran and other seeds and grains, then neutralized to its sodium salt.
Questions everyone asks
What does sodium phytate do in sunscreen?
It is a chelating agent that binds trace metal ions, helping prevent oxidation and keeping the formula stable.
Where does sodium phytate come from?
It is the sodium salt of phytic acid, a compound naturally found in plant seeds and grains such as rice bran.
