Aluminum IRON CALCIUM MAGNESIUM GERMANIUM SILICATES is an inorganic chemical compound, a ceramic powder consisting mostly of silicon dioxide, aluminium oxide, ferric oxide, calcium oxide, magnesium oxide and germanium oxide.

What it is used for and where

Cosmetics

Antimicrobial agent. This ingredient is able to suppress or inhibit the growth and replication of a broad spectrum of microorganisms such as bacteria, fungi and viruses by making the stratum corneum temporarily bactericidal and fungicidal.

Antioxidant agent. Ingredient that counteracts oxidative stress and prevents cell damage. Free radicals, pathological inflammatory processes, reactive nitrogen species and reactive oxygen species are responsible for the ageing process and many diseases caused by oxidation.

Safety

Aluminium can interfere with different biological processes (cellular oxidative stress, calcium metabolism, etc.), so it can induce toxic effects in different organs and systems, and the nervous system is the main target of its toxicity.

A warning should be given about the risk of aluminium intake, which cannot be ruled out as this ingredient can be found both in cosmetic products and in widely consumed foodstuffs such as bread, various baked goods (1).
