About

An inorganic antimicrobial complex incorporating silver with aluminum and magnesium phosphates, offering broad-spectrum preservation potential.

Silver Magnesium Aluminum Phosphate is a composite inorganic material produced by reaction of silver oxide with phosphorus pentoxide, magnesium oxide, and aluminum oxide under high temperature. The silver component provides antimicrobial properties, while the phosphate matrix moderates silver ion release. Silver-based preservatives have a long history in medical applications, though their use in cosmetics is limited and raises questions about potential silver accumulation with long-term use. The ingredient is not specifically addressed in EU Regulation 1223/2009 Annexes.
