A diluted solution of ethanol
is most commonly used as a solvent for perfumes. Some manufacturers
also use lipids like jojoba or fractionated coconut oil as solvent
for scents. The intensity and longevity of a perfume increases
in direct proportion to the percentage of aromatic compounds
used in it. Fragrances are typically made of three notes, the
top, the middle and the base that unfold themselves gradually
as one applies scent on her or his body. The top note leaves
an immediate impression while middle and base notes gradually
appear later. Raw material for scents can be sourced from plants
and animals or they can be synthesized artificially as well.
Plant sources could include
flowers, fruits and bulbs while animal sources typically include
civet musk, honeycomb and ambergris. Rare and expensive aromatic
compounds like coumarin and linalool are generally synthesized
artificially. Companies like Givaudan, Symrise and Takasago are
the leading manufacturers of artificially synthesized perfumes.
Different types of fragrant extracts like absolute, tincture
and pomade are used to manufacture scents. Fragrant extracts
are commonly known as essential oils.
Fragrances require proper upkeep
and preservation. Most of them will degrade in the presence of
strong heat and light. Therefore, they should be kept away from
a heat source or strong light. Scents can usually maintain their
aroma for about a year if left open. An almost empty bottle of
scent will degrade faster than an almost full bottle as oxygen
increases the rate of scent degradation.
Many modern cologne and men perfumes are made using
different combinations of fragrance bases. A fragrance base is
essentially a modular perfume which has been blended with aromatic
chemicals and essential oils. Perfumes usually contain tens of
thousands of ingredients and it may be quite difficult to analyze
their formula. However, generally all scents use four groups
of ingredients that are combined in different proportions. These
four basic ingredient groups are primary scents, blenders, modifiers
and fixatives. Men perfumes vary to a great extent in their composition
and also use different ingredients. Keeping in mind the interests
of fashion conscious men, leading manufacturers of scents have
rolled out a range of men perfumes into the markets in past few
years. |
