About

An inorganic ceramic material made of iron, barium, and oxygen — primarily used in industrial magnetic applications, with no established role or safety profile in topical cosmetic products.

Barium hexaferrite (BaFe12O19) is a crystalline ferrite ceramic material belonging to the magnetoplumbite family, with a complex hexagonal crystal structure. It is one of the most widely used permanent magnetic materials in electronics, motors, and data storage due to its high coercivity and chemical stability. In cosmetic contexts, its presence is unusual — it is not a typical cosmetic ingredient and its function is listed as 'NOT REPORTED'. Barium is a heavy alkaline earth metal whose soluble salts (barium chloride, barium nitrate) are toxic by ingestion due to barium ion effects on potassium channels and cardiac function. The hexaferrite form is extremely insoluble, which reduces systemic absorption risk, but the complete absence of cosmetic safety data and the general unsuitability of industrial ceramic materials for topical application makes this ingredient a significant concern.

Function

NOT REPORTED

Known concerns

  • Industrial material with no established cosmetic safety data
  • Barium exposure from insoluble salts has unknown dermal absorption potential
  • Not reported function suggests undeclared or accidental ingredient presence
  • May contain trace heavy metals from manufacturing process
