Dusting Analysis
Zinc Phosphate is primarily utilized in dental products, not as a common active ingredient in topical skincare, thus dusting is not typically a concern in this context.
The Formula
Formulation
Stability
Zinc Phosphate is practically insoluble in water but can dissolve in strong acids and ammonium hydroxide, which impacts its formulation stability.
Conflicts
- Oxidizing agents
- Reducing agents (e.g., hydrides, due to risk of forming phosphine gas)
- Strong acids
Safety
Safety Profile
The CIR Expert Panel found Zinc Phosphate safe in cosmetics at current use concentrations, provided formulations are non-irritating. While not an FDA-approved active for topical skincare, it is listed as a food contact substance and used in FDA-cleared dental cements.
