About

A rose ketone (damascone variant) restricted under EU Annex III/164 due to its skin sensitization potential.

Rose Ketone-5 is a damascone-type fragrance ketone (CAS 33673-71-1) restricted under EU Annex III with reference 164. Like other rose ketones, it provides powerful fruity-rose notes but carries sensitization concerns. The specific isomer configuration that defines Rose Ketone-5 requires concentration restrictions in leave-on products. IFRA standards apply for safe use levels, and EU cosmetic formulations must comply with these restrictions.
