Trimethylcyclopentenyl Methylisopentenol

Trimethylcyclopentenyl Methylisopentenol (CAS 67801-20-1) is one of the fragrance allergens the European Union requires to be named on a label once it passes a threshold. It is rarely something you added on purpose: 3 materials in this catalog carry it as a constituent, which is how a formula ends up over the line without a single line item admitting to it.

What Trimethylcyclopentenyl Methylisopentenol smells like

Intense, powerful synthetic sandalwood with a rich, warm, natural creamy-milky character and subtle musky facets; far stronger than the natural oil. A workhorse for modern sandalwood accords.

It is a material in its own right, not only a line on a label: its catalog page carries the full profile.

Estimates from typical published compositions, not a certificate of analysis for your bottle. A supplier's own figures always win.

PerfuMate totals these across a whole formula while you compose, counting the same molecule arriving from several materials at once, and writes the declaration for the back of the bottle. Start a formula, free. No account needed.
