About

A fragrance ketone with aquatic toxicity and skin irritation warnings, bearing structural similarity to restricted ionone derivatives.

Dimethylcyclohexyl 3-butenyl ketone is a synthetic fragrance ingredient structurally related to ionones but with modifications that alter its allergenic profile. It carries H411 (aquatic chronic toxicity) and H315 (skin irritation) classifications. The butenyl side chain introduces additional sensitizing potential compared to simpler ionones. EU regulations on this specific compound require concentration limits in leave-on skin products.

Known concerns

  • H411: Aquatic chronic toxicity
  • H315: Skin irritation
  • Sensitization potential from unsaturated side chain
  • EU fragrance allergen considerations
