Sodium Polyaspartate
Ingredient Info
Sodium polyaspartate is a synthetic polymer derived from the amino acid aspartic acid. In skincare, it functions primarily as a chelating agent and film-former, helping to bind minerals and maintain product stability while potentially providing mild anti-stain properties.
Benefits
- May help reduce visible staining on skin surface
- Helps stabilize skincare formulations
- Chelates minerals that can affect product performance
Science: Clinical evidence comes primarily from dental care studies, where sodium polyaspartate showed statistically significant anti-stain efficacy at 3 months in toothpaste formulations. Direct peer-reviewed data on topical skincare application is limited, though the ingredient's safety profile and mechanism suggest similar chelating benefits may apply to cosmetic use.
