Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A very broad bacterial genus that ranges from harmless (B. subtilis) to seriously pathogenic (B. cereus, B. anthracis). Without species-level specification this INCI entry warrants real caution.

Skin benefits

  • Source of fermentation-derived peptides
  • Some Bacillus species support skin microbiome
  • Source of enzymes (proteases, lipases)
  • Spore-forming — stable in formulation

Known concerns

  • Genus includes pathogens like B. cereus and B. anthracis
  • Species-level identification essential for safety
  • Spore-forming bacteria are hard to fully inactivate
  • Possible toxin (cereulide) production by some species
  • Limited cosmetic-specific safety review
