TRIMETHYL-2-CYCLOHEXENYL-3-PENTANONE/2-PROPYNOL.

Questionable CAS 68611-23-4 / PERFUMING

This compound, chemically identified as 3-Pentanone, 1-(2,6,6-trimethyl-2-cyclohexen-1-yl)-, reaction products with 2-propyn-1-ol, functions primarily as a fragrance component within cosmetic formulations. While 98.8% of its GHS classifications indicate it does not meet hazard criteria, its structural kinship to recognized skin irritants and sensitizers necessitates prudent consideration.

Safety

CIR Status
Not reviewed
Sensitization risk Moderate

The U.S. EPA's TSCA Inventory lists this ingredient as 'Active'. While GHS classifications for this specific compound indicate a low hazard profile in 98.8% of analyzed reports, a notable concern arises from its structural resemblance to known cyclic ketone fragrance ingredients that are established skin irritants and sensitizers, including the EU and California-classified allergen Alpha-Isomethyl Ionone.

Our Assessment

Questionable

Its primary role as a fragrance, an unreviewed safety status by CIR, and potential for irritation and sensitization (derived from structurally similar compounds) render its utility in precision skincare questionable without further specific safety and efficacy data.
