Ingredients for Perfumery

Ingredients for perfumery that consist of a mixture of multiple materials produced to a consistent formula. Includes both industry standard bases and proprietary blends and bases.

Ingredients with fixative properties. Many materials have some fixative properties or are routinely used to extend the odour of shorter lived ingredients. Most have odours of their own and few will fix all materials: to appear in this category a material must have useful fixative effects on a range of materials.

Ingredients for perfumery that are normally liquid at room temperature in the form supplied.

Ingredients for perfumery where the primary constituent is one molecule, whether synthetically produced or extracted from a natural product. Note that purity levels vary a great deal and some molecules are mixtures of multiple isomers.

Ingredients for perfumery that are normally solid at room temperature in the form supplied. These includes crystals, powders and materials that are normally melted prior to use. Note that some materials, particularly when supplied in small containers, may remain liquid even when cooled although larger amounts will solidify.

Materials used primarily as solvents or additives, usually odourless or nearly so. Note that most liquid perfumery materials will also function as solvents: this category is for those used for that purpose either as general solvents or for particular materials. Also in this category are additives with other functions, such as stabilisers, that are either odourless or not mainly used for their odour.
