Safety score · 0–100

Fine

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

A manuka-oil beta-triketone with antimicrobial activity. Same chemistry inspired the mesotrione herbicide, so cosmetic data is thinner than for everyday plant extracts.

Skin benefits

  • Beta-triketone constituent of manuka oil
  • Antimicrobial activity
  • Used in manuka-derived skin formulas

Known concerns

  • Plant-protection herbicidal analogue (mesotrione is derived from it)
  • Limited cosmetic-specific safety data
  • Potential aquatic toxicity
