Science
Mechanism of Action
This ingredient functions by modulating the pH of cosmetic solutions, maintaining them within a stable range, typically between 7.0 and 9.0. Furthermore, its ability to complex with heavy metal ions contributes to formulation stability by preventing unwanted reactions and degradation over time.

Formulation
Stability
Potassium Tartrate is stable and actively aids in maintaining optimal pH levels within formulations, contributing to their overall stability and extending shelf life. A 1% aqueous solution of Potassium Tartrate exhibits a pH between 7.0 and 9.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deferred evaluation of Potassium Tartrate, citing its prior assessment by the FDA. The FDA affirmed its status as Generally Recognized As Safe (GRAS) for direct food use (as E336), with no concentration limitations beyond current good manufacturing practices. Its manipulation poses minimal risks, indicating a favorable safety profile for cosmetic applications.
