About
A small, volatile, flammable ketone used at trace levels in perfumery — in the solvent/irritant category rather than a mainstream cosmetic material.
Cyclopentanone (CAS 120-92-3) is a five-membered ring ketone used as a chemical intermediate and as a flavor/fragrance constituent. It is classified as a flammable liquid (H226) with skin, eye, and respiratory irritation hazards (H315/H319/H335). Its volatility and reactive ketone chemistry are consistent with a solvent/intermediate role rather than a cosmetic skin-contact material. Used at trace levels for fruity-minty top-notes. No supportive CIR/SCCS cosmetic monograph — industry use is managed under fragrance-industry practice only. Conservative orange placement rather than higher rating.
