Fragrance allergens › Hexamethylindanopyran
Hexamethylindanopyran (CAS 1222-05-5) 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: 17 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.

The benzyl benzoate cut of Galaxolide, one of the standard commercial grades ScenTree lists alongside the IPM, DEP and DPG dilutions. The musk itself is IFF's clean, powerful and versatile iso-chroman musk with exceptional persistence, a quality approaching the tone of macrocyclic musks; supplier odour tags are musk, floral, woody, clean, with berry and milky facets in the drydown. It holds a blotter past two days and carries bloom and lift into the base. The carrier is not neutral the way IPM is: benzyl benzoate is itself faintly sweet-balsamic, it is a listed fragrance allergen, and it can discolour a pale base, so this grade behaves differently from the IPM cut even though the musk is identical. Dosed straight from the bottle at roughly twice the weight of neat Galaxolide.
It is a material in its own right, not only a line on a label: its catalog page carries the full profile.
0 of the 20 carriers in this catalog are naturals and 20 are synthetic. The heaviest carrier that is not the molecule itself is White Musk Blend, at about 40%.

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.
