The Formula
Formulation
Stability
Optimal stability and antioxidant activity are observed within a precise pH range of 5.5 to 6.5. As a carboxylic acid, its solubility and stability are pH-dependent, demonstrating increased solubility when ionized at higher pH values. It has been successfully formulated alongside physical UV filters such as titanium dioxide (TiO2) and zinc oxide (ZnO).
Conflicts
- Due to its inherent acidic nature, potential reactivity with certain excipients requires careful formulation consideration.
- Its acidic properties may also lead to potential corrosion or degradation of specific packaging materials.
