Evaluated by RIFM as part of the 'cyclopentanone and cyclopentenone group' of fragrance ingredients, with no safety concerns at reported levels of use. Maximum dermal exposure for high-end users is calculated to be up to 15.16% in hydroalcoholic products. While undiluted cyclopentanone can cause skin and serious eye irritation, minimal evidence of skin irritation is associated with its current levels of use in cosmetic products. It is not classified as a respiratory or skin sensitizer. Specific SCCS or FDA cosmetic status beyond FEMA recognition as a flavor/fragrance ingredient is not available.
