Fermentation Derivative

GLIOCEPHALOTRICHUM SIMPLEX/FERROUS SULFATE/TYROSINE FERMENT FILTRATE

Safety score · 0–100

Moderate

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

A proprietary fungal ferment filtrate with ferrous sulfate and tyrosine. Obscure ingredient with thin safety data and oxidation-chemistry concerns.

This ingredient is a filtrate of Gliocephalotrichum simplex fermentation with ferrous sulfate and the amino acid tyrosine added. Gliocephalotrichum species are plant-pathogenic fungi not commonly used in cosmetics; the combination with ferrous sulfate (an iron-II salt that catalyzes Fenton-type reactive-oxygen generation in the presence of peroxides) plus tyrosine (a melanin precursor) suggests a pigment-modulation or antioxidant angle, but independent peer-reviewed dermal toxicology is effectively absent. EU CosIng listing without restriction is not a substitute for a real safety dossier here.

Skin benefits

  • Proprietary fermentation-derived active
  • Contains tyrosine-related metabolites
  • Marketed for skin-conditioning effects

Known concerns

  • Gliocephalotrichum is a plant pathogen fungus — unusual source
  • Ferrous sulfate catalyzes oxidation / Fenton chemistry
  • Very thin independent safety dossier
  • Unvalidated cosmetic use history
