Sodium phytate is the synthetic salt form of the antioxidant phytic acid. In this form, it works as a chelating agent, keeping metals from binding to water in cosmetics. This also helps stabilize the formula.
Sodium phytate is described as a hygroscopic powder (meaning it’s a substance that attracts moisture from its surroundings) and is considered highly soluble in water.
The Cosmetic Ingredient Review’s latest assessment of sodium phytate (in 2018) reaffirmed its status as a safe cosmetic ingredient. Their report surveyed 412 products ranging in 0.0099-0.5% concentration. (Only small amounts of this ingredient are needed to enable its chelating function.)
