About

Dnoc (iso) is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

DNOC (4,6-dinitro-ortho-cresol) is a highly toxic nitro-phenol pesticide historically used as an herbicide, insecticide, and ovicide. ECHA classifies DNOC as a substance of very high concern due to its acute toxicity, mutagenicity concerns, and environmental hazard profile. It is expressly listed in EU Cosmetics Regulation Annex II (list of substances prohibited in cosmetic products) under entry 94. Any cosmetic product containing DNOC would be non-compliant with EU market placement requirements.

Known concerns

  • EU Annex II banned substance
  • SVHC - very high concern under REACH
  • Acute toxicity
  • Potential mutagen
  • No cosmetic use authorized
