A safety assessment by the Research Institute for Fragrance Materials (RIFM) for this specific ingredient (CAS 154171-77-4) concludes its safety as a fragrance ingredient. Structurally similar compounds have been evaluated and found not to be genotoxic, PBT (Persistent, Bioaccumulative, and Toxic), photoirritating, or photoallergenic. One analogue demonstrated a No Expected Sensitization Induction Level (NESIL) of 5300 µg/cm² for skin sensitization. However, a Safety Data Sheet for a very closely related chemical (CAS 154171-76-3) classifies it as causing serious eye irritation and notes it is suspected of damaging fertility or the unborn child. This warrants extreme caution for use, especially in sensitive populations.

Our Assessment

Verdict

Questionable

Lacking any direct skincare benefits and presenting nuanced safety considerations due to a closely related chemical, its inclusion solely for perfuming is questionable for precision skincare formulations.
