Perfumes..

Perfumes are a mixture of essential oils and aromas. The smell of a particular perfume will vary slightly from woman to woman, as each person’s individual skin chemistry and body temperature will react slightly differently to a given scent, so each individual will have a different preference when choosing a perfume.

On application, body heat causes the solvent to evaporate quickly, leaving the fragrance to evaporate gradually over several hours. The rate of evaporation(vapor pressure) and the odor strength of the compound partly determines the tenaciousness of the compound and determines it perfume note classification.

Top notes: Scents that are perceived a few minutes after the application of a perfume. Top notes create the scents that forms a person's initial impression of a perfume. Because of this, they are very important in the selling of a perfume. The scents of is note class are usually described as "fresh", "assertive" or "sharp". The compounds that contribute to top notes are strong in scent, very volatile, and evaporate quickly. Citrus and ginger scents are common top notes.

Heart notes or Middle notes : The scent of a perfume that emerges after the top notes wear-down. The heart note compounds form the "heart" or main body of a perfume and acts to smooth the sharpness from the initial impression of perfume that caused by the top notes. Not surprisingly, the scent of heart note compounds are usually more mellow and "rounded". Scents from this note class appear anywhere from 10 minutes to 1 hour after the application of a perfume. Lavender and rose scents are typical heart notes.

Base notes: The scent of a perfume that appears after the departure of the heart notes. Base Notes bring depth and solidness to a perfume. Compounds of this class are usually the fixatives used to hold and booster the strength of the lighter top and heart notes. The compounds of this class of scents are typically rich and "deep" and are usally not perceived until 30 minutes after the application of the perfume or during the period perfume dry-down . Musk, vetiver and scents of plant resins are commonly used as base notes.

You may already enjoy choosing from a wide variety of very different perfumes, selecting whichever best suits your mood on a given day. However, women’s perfume fragrances can be split into seven different olfactive families, as follows:

Aldehydic
This group of perfumes contains chemicals from the aldehyde group. The most famous perfume in this group is Chanel No.5, which was also the first aldehydic perfume to be created.


Chypre
Named after the perfume of the same name created by Coty in 1917, perfumes in this category have a base of bergamot, labdanum, patchouli and oakmoss, which gives a mixture of woody and floral tones. The scent of chypre perfumes tends to be very rich and long-lasting.

Citrus
These perfumes are fresh and light, and traditionally have been used only as eau de colognes, as the fragrance tends to be subtle. Citrus scents include bergamot, grapefruit, lemon, orange and tangerine.

Floral
As the name suggests, the dominant fragrances in floral perfumes are derived from one or several types of flower. This is a very popular group, and floral perfumes tend to be suitable for any occasion. To ensure that the fragrance is long lasting, you should purchase perfumes at the quality end of the scale, as cheaper perfumes tend to use lower quality oils, which can make a difference in this group.

Fougere
The term ‘fougere’ means fern in French, and perfumes in this category feature a base of oakmoss, lavende and coumarin which combine to produce a woody, herbaceous scent that is especially popular in men’s fragrances. The first fougere perfume was Houbigant’s Fougere Royale (Royal Fern), created in 1882.

Oriental
Oriental perfumes form another large olfactory group. Also known as ambers, perfumes in this category are often described as warm and sensual. The scents for these perfumes come from musk, vanilla and exotic woods.

Woody
Perfumes with fragrances that are derived from woods such as cedar, patchouli, sandalwood and vetiver are part of the woody group.
They are more commonly found in men’s fragrance ranges, but there are still several women’s perfumes in this family (usually described with Oriental or Floral tones as well).

Perfumery Chemicals
Perfumery compounds or chemicals are essential elements for aromatic perfumery chemicals. These perfumery chemicals are volatile components of different plants by steam distillation, that contribute to various aromas. These perfumery chemicals are key components in a number of successful perfumery and cosmetic industries. These are some of the examples of perfumery chemicals includes benzyl acetate,

benzyl benzoate, cyclamen aldehyde, diphenyl methane, ethyl phenylacetate, methyl phenyl acetate, alpha amyl cinnamic aldehyde and para cresyl phenyl acetate.
