Science
Mechanism of Action
This compound is classified as an antimicrobial agent. Its silver component is responsible for its antibacterial action, which can be further enhanced by magnesium. Magnesium is understood to promote cell migration via pathways such as MEK/ERK/MMP7, and has been observed to enhance keratinocyte proliferation and neovascularization, suggesting a potential role in supporting wound healing and contributing to general skin health.

Stability
Studies on related magnesium phosphate minerals indicate stability at physiological pH, with precipitate formation only occurring at concentrations 10-100 times higher than physiological levels. Compatibility assessments involving magnesium sulfate and sodium phosphate intravenously demonstrated no notable alterations in pH, turbidity, or visual appearance.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed SODIUM MAGNESIUM SILVER PHOSPHATE. While the Scientific Committee on Consumer Safety (SCCS) initially allowed micron-sized particulate Silver up to 0.2% in rinse-off and 0.3% in leave-on products, a more recent SCCS opinion (June 2024) concluded that micron-sized particulate Silver is not considered safe at these concentrations for general cosmetic use, with exceptions for specific oral and eye shadow products. Although this specific ingredient has not been explicitly reviewed by SCCS, the safety concerns regarding its silver component are significant. No specific FDA status for this ingredient in cosmetics has been identified.

Verdict
While SODIUM MAGNESIUM SILVER PHOSPHATE exhibits antimicrobial properties, recent SCCS opinions deeming micron-sized particulate silver unsafe for general cosmetic use, despite this specific compound being unreviewed, necessitates avoidance due to significant safety concerns regarding its silver component.
