Use the search and family filters to compare materials by name and broad scent character. Each profile describes one material, suggests what to observe, and links to a supplier reference. The top, heart, or base label is a study aid. It does not predict a fixed evaporation time, and the same material can behave differently with a change in dilution or surrounding formula. Pairing suggestions are starting questions for a study.

Record the exact product name, supplier, grade, lot, and stock strength alongside your observations. Similar names do not guarantee identical products: a natural extract, an isolated molecule, and a supplier blend can have different compositions. The description in this library follows the cited reference. Check your own bottle and documentation before using that description to identify the material in your collection.

Compare materials consistently

A useful study changes as few conditions as possible. Record the dilution and solvent, label each blotter, and compare observations at the same elapsed times. Write down your own description before reading it against another person’s account. If you change the stock strength, create a separate record so you can distinguish a concentration effect from a different material or formula revision.

Use the blotter journal for observations and the formula builder for quantities. When working with a prediluted material, enter its stock strength separately from the amount weighed; those values describe different things. The library does not supply recommended use levels or a restrictions database. Supplier specifications and the requirements for the intended application remain separate from scent descriptions, note roles, and educational pairing ideas.
