The signature molecule of orris root: dry, powdery iris with violet, woody and faintly waxy-carrot facets of exceptional refinement. Used sparingly to give true iris character where orris butter is too costly or too fatty.

Every regulatory join - IFRA, GHS, allergens - is by CAS number, and a material can supply one through its constituents as well as its own row, so of the 569 materials carrying no CAS number the 244 without a constituent table are the ones that return "nothing known" rather than "nothing applies". The blotter hours are sourced rather than measured by us, and the app labels every one of them an estimate. There is no physical chemistry on a row: no molecular weight, no vapour pressure, no boiling point. The longer answer, or the whole catalog counted.
