terpenes and sesquiterpenes
• Odor profile of EOs determined by delicate
ratio of constituents
– DNA or genetic footprint
– Example: Lavender vs. Lavandin
– Variation from species to species, even plant to plant
• Can change to adapt to the environment

• External Secretory Structures– Glandular trichomes found on surface of plant; responsible for the
production of EO chemicals
– Plants with glandular trichomes: Basil, Lavender, Marjoram, Melissa,
Oregano, Peppermint, Rosemary, and Spearmint
• Internal Secretory Structures– Secretory cavities and ducts consisting of large, intercellular spaces;
formed by separation of neighboring cell walls or by disintegration of cells
– Plants with secretory cavities: Grapefruit, Lemon, Eucalyptus, Orange
– Plants with secretory ducts: Caraway, Dill, Fennel, Fir, Cedar, Juniper
• Essential oil cells– Found within plant tissue throughout the plant
– EOs with cells: Black pepper, Cinnamon, Ginger, Lemongrass, Nutmeg
Where do plants make and store Essential Oils?

Refractive Index• A number that describes how light propagates through that medium.
• Defined as n = c/v where c is the speed of light in a vacuum and v is
the phase velocity of light in the medium.
• For example, the refractive index of water is 1.333, meaning that light
travels 1.333 times faster in a vacuum than it does in water.
Optical Rotation• The rotation of the plane of polarization of linearly polarized light as it
travels through certain materials
• Optical activity occurs only in chiral materials, those lacking
microscopic mirror symmetry.
• The rotation of the plane of polarization may be either clockwise, to
the right (dextrorotary — d-rotary), or left (levorotary — l-rotary)
depending on which stereoisomer is present (or dominant).
• Optical activity is measured using a polarized source and polarimeter.
Specific Gravity• The ratio of the density of a substance to the density of a reference
substance (usually water)
• Equivalently, it is the ratio of the mass of a substance to the mass of a
reference substance for the same given volume

Essential oils are priced based
on the following factors:
• Yield from crops
• Labor
• Extraction Techniques
• Availability and demand
Pricing of Essential Oils
![Page 65: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/65.jpg)
• Certain oils require more plant material
to generate a substantial amount of oil
• It takes about 4 tons (1,600,000) rose
petals to make 1 kg of oil
• It takes about 0.055 tons of eucalyptus
leaves to make 1 kg of oil
• Rose oil is far more expensive than
eucalyptus oil
• Market price for Bulgarian Rose Oil is $5,126/lb (25 lb pricing)
• Market price for eucalyptus oil is $9.50/lb
(drum pricing)
Yield From Crops
![Page 66: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/66.jpg)
Harvesting procedure affects pricing of essential oils
Cost of Labor
Oranges Jasmine
• Harvested in bulk at any time of
the day
• Gently picked no later than
10am on the day of harvest
• Mechanically harvested • Hand picked, labor intensive
• Market price is $8/lb (drum) • Market price is $2,600/lb (drum)
![Page 67: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/67.jpg)
• Most citrus oils are extracted via
cold press
• Most essential oils are extracted
by distillation
• Essential Oils produced by supercritical fluid extraction (SFE)
tend to be more expensive than other extraction methods
• SFE equipment costs hundreds of thousands of dollars
• Ginger oil from SFE is $865/lb compared to $37/lb from distillation
Extraction Techniques
![Page 68: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/68.jpg)
• A shortage or limited supply in any essential oil
will drive up the price.
• On the other hand, an overflow of any essential
oil in the market might drive prices down.
• A strong demand of an essential oil will push
prices up.
Availability and Demand
![Page 69: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/69.jpg)

on various factors:
• Weather Conditions
• Crop Issues
• Geographical Location
• Politics
Fluctuation in Pricing

• Heavy rains/storms during growing and
harvesting periods may delay crop
collection and processing.
• This could lead to temporary shortages
and price hikes.
• Haiti is the world’s leading producer of
vetiver oil—constantly suffers from severe
heavy rains and tropical storms.
• Consequently, vetiver oil production is
reduced due to a decrease in root yield.
• Shortage caused fluctuation in vetiver
prices from $170/lb to $230/lb
Weather Conditions
![Page 71: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/71.jpg)
• Delays and reduction in new crop
growth also causes shortages and
may increase price.
• If new crops have better yields than
previous years, there’s a possibility
prices could drop.
• Florida is a leading producer for
grapefruit production.
• Recently grapefruit trees have been
suffering from HLB virus
– Major reduction in grapefruit yield
– Resulted in price hikes; price of
grapefruit EO continues to rise
Crop Issues

• Crops from various geographical locations
tend to vary in quality and price.
• Traditional sandalwood oil is from India
and is very rare to obtain.
• Indian sandalwood is a higher grade and
better quality than sandalwood from other
regions.
• Australian sandalwood is the most widely
purchased sandalwood today.
• Even though Australian sandalwood is not
the same genus as Indian sandalwood, it’s
price is still high due to investment in
agricultural techniques.
Geographic Location

• Indian sandalwood is the most known source of
sandalwood oil.
• Government restriction of private ownership of
sandalwood plantations has led to a shortage and hence continuous price increases of sandalwood oil.
• As local currencies in Indonesia and Brazil weaken
against the US dollar, prices for products in these
countries have declined.
• If currency in these countries appreciate, this will be
reflected through an increase in the US dollar price.

IFRA Standards
• Prohibited: cannot use at all (0.1% is acceptable as
“unavoidable impurities” in raw materials such as essential oils)
– Verbena Oil (Phototoxicity and Sensitizing)
• Restricted: can use the material but only below a certain
concentration in the finished product
– Bergamot Oil (Phototoxicity) Nutmeg(Safrole content < 0.01%)
• Specification: adhere to specific purity criteria
– Cade Oil (Rectified) limited PAH
Linalool and natural products to be rich in linalool, such as bois de rose, should only
be used when the level of peroxides is kept to the lowest practical level. It is recommended
to add antioxidants at the time of production of the raw material. The addition of
0.1% BHT or alpha-tocopherol has shown great efficiency.

EOs are the foundation of perfumery…
![Page 94: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/94.jpg)
It Starts with the Basics
• Essential oils are the OG fragrance materials
– Biblical references to EOs
– Egyptian use for embalming
• Learning addition and subtraction comes before
multiplication
• Popularity of these types has continued despite the
increase in options from new odor molecules
![Page 95: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/95.jpg)
EOs can cost a lot of money…
![Page 96: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/96.jpg)
A Rough Guide to Cost
• Orange Oil $
• Lavender Oil = $$
• Ginger SFE = $$$
• Rose Oil = $$$$$$
• Orris Absolute = If you have to ask then you
can’t afford it

EOs have irreplaceable character…
![Page 98: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/98.jpg)
Time, Cost, Quality
• Plants are master perfumers in their own rite and
EOs should be considered plant derived fragrance
formulas
• It’s cheaper to use EOs than a perfumer trying to
recreate that character
• Perfumers consistently look to essential oils when the
price allows it
• Perfumer will also remove costly synthetics to use
more EOs
![Page 99: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/99.jpg)
EOs are single materials…
![Page 100: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/100.jpg)
EOs are always natural…
![Page 101: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/101.jpg)
EOs are regulated by the FDA under
the Food and Cosmetic Act…
![Page 102: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/102.jpg)
Highly Sought, Poorly Understood
• The FDA has a limited scope
• Same goes for USDA
• Understanding the precise wording on how
suppliers define EOs is important
• Ask about "pure & natural" when in doubt
![Page 103: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/103.jpg)
The FDA does not define the terms “organic,”
“natural,” nor “essential oil” in cosmetics…
![Page 104: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/104.jpg)
The characteristic smell of an EO
is what makes it an EO…

EOs smell better than fragrances
made from synthetic materials…
![Page 106: Welcome to Fragrance 301 - Orchidiaorchidia.com/wp-content/uploads/2017/03/presentation_frag301_2017... · Welcome to Fragrance 301 ... Morning Session What Are Essential Oils?](https://reader030.vdocuments.us/reader030/viewer/2022020412/5aef1db07f8b9a8c308b82d8/html5/thumbnails/106.jpg)
Essential Oils Can be Limiting
• Specific fragrance characters with well
established appeal for consumers cannot
be achieved with EOs alone
• The most popular fragrances achieve their
character from the creative blending of
naturals AND synthetics
