Trimethylcyclopentenyl Methylisopentenol
Trimethylcyclopentenyl Methylisopentenol
A fragrance ingredient also known as Ebanol and chemically described as 3-Methyl-5-(2,2,3-trimethyl-3-cyclopentenyl)pent-4-en-2-ol. It is used to impart a woody, musky, or amber-like scent in cosmetic and personal care products. It functions as a perfuming agent rather than a treatment active, and is typically included at low levels in finished formulations.

Risks & Warnings
Main concern is fragrance sensitivity: it may trigger irritation, stinging, or allergic contact dermatitis in susceptible users, especially on compromised or very sensitive skin. As a volatile perfume ingredient, it may also be problematic for people with fragrance intolerance or respiratory sensitivity. There is no evidence here that it is intrinsically comedogenic, but fragranced products can still worsen acne indirectly in some users by irritating skin.
