The Formula
Formulation
Stability
Formulations are most stable with a pH between 4.5 and 5.5. Care must be taken to avoid sharp drops in pH below 7.5, as zinc ions can become more soluble, leading to potential instability.
Conflicts
- Low pH environments (below 7, especially below 7.5)
- Certain thickeners
- Film-formers
Safety
