Fragrance materials A to Z
The index currently holds 2,672 aroma chemicals, essential oils, absolutes and solvents. Every entry carries what a perfumer needs before weighing a material: how it smells, how long it lasts, what it is chemically, and how far it may be dosed under the IFRA Standards.

What is in the index
Every material page collects the same set of facts, so two candidates can be compared side by side: the written odor description, the note tier (top, heart or base), odor impact and tenacity, the CAS number and INCI name, molecular data, boiling and flash point, density, refractive index and solubility, the IFRA maximum concentration for all eighteen product categories, and the substances that must appear on the label under Annex III of the EU Cosmetics Regulation.
The figures are guide values gathered from public reference works and supplier declarations. They differ between batches, origins and qualities, so the data sheet of your own supplier is always the authoritative document for the material you actually use.
