A bicyclic tertiary alcohol fragrance ingredient with acute oral toxicity (H302) and limited cosmetic safety data.

8-Ethyl-1,5-dimethylbicyclo-8-octanol is a bridged bicyclic tertiary alcohol used as a fragrance ingredient with woody, balsamic odor character. Its H302 classification (harmful if swallowed) indicates acute oral toxicity concern, though dermal toxicity is considered low for most tertiary alcohols. The bicyclic structure limits metabolic breakdown, potentially leading to systemic exposure. EU fragrance industry reviews note limited data for this specific ingredient, warranting additional safety assessment before use in children's products or lip/oral area cosmetics.

Known concerns

  • Acute oral toxicity (H302) - harmful if swallowed
  • Limited chronic and reproductive toxicity data
  • Bicyclic structure may persist in environment
