CRYPTOCOCCUS/HUMUS FERMENT FILTRATE

65

Safety score · 0–100

Fine

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

A ferment of humus (soil-derived organic matter) by Cryptococcus yeast. Used for antioxidant claims; the chemistry is plausible but the obscure substrate and lack of public safety data hold the score down.

Skin benefits

  • Yeast-fermented humic substances
  • Antioxidant phenolic and humic acids
  • Trace minerals from humus substrate

Known concerns

  • Humus is a heterogeneous substrate — composition varies
  • Cryptococcus species are usually non-pathogenic but require sterility check
  • No public CIR/SCCS dossier
