Essential Oils, Absolutes, and Fragrances
These are natural, fragrant oils extracted from plant matter.
Essential oils are most often extracted from grasses, roots,
leaves, flowers, fruit and seeds. Extraction is generally done
using steam distillation, extraction via liquid carbon dioxide
or other solvent or by pressing or squeezing.
Are highly concentrated, alcohol soluble extracts of natural
perfume materials. Absolutes are usually prepared thru
alcohol extraction. The alcohol is subsequently removed so that
the finished absolute will be completely soluble in designer
perfumes and colognes.
Fragrances and Fragrance Compounds:
These are usually blends of natural essential oils, ingredients
isolated from them, synthetic aromatic chemicals, natural
resins, balsams and fixatives.
A finished fragrance compound blends a balance of:
I. Top Notes: The fastest evaporating ingredients, which
give the first impression of the fragrance.
II. Middle notes: The main body of the fragrance, which
predominates most of the extent of the fragrance, and provides
the main character of the scent.
III. Base Notes: The slowest evaporating and longest
lasting part of any fragrance. They include ingredients which,
by themselves, as well as fixatives will give longer lasting
properties to a fragrance.
