<<0>> hello everyone i'm dr prabhu satel
<<3>> working as chief scientific officer for
<<6>> aromatic plant research center
<<9>> i've been involved on essential research
<<11>> since
<<12>> 10 years and today i'm going to talk
<<14>> about my past experience on essential
<<17>> oil analysis
<<18>> what i have seen unfortunately as the
<<20>> demand for
<<22>> essential oils has increased the
<<24>> incentives for dishonest
<<26>> people to cut corner with inferior
<<29>> product has also
<<30>> increased when consumers use these
<<34>> inferior products their perception of
<<37>> essential oils and their efficacy
<<40>> suffers
<<41>> before doterra there was no industry
<<43>> standard
<<44>> on essential oils i have been
<<47>> researching
<<48>> essential oil adulteration since more
<<51>> than 10 years
<<53>> today i will share my data and
<<55>> experiences
<<56>> i hope you will like this before
<<59>> going through this presentation i would
<<61>> like to define
<<62>> adulteration adulteration can be defined
<<65>> as a process
<<67>> by which quality or nature of a given
<<69>> oil is
<<70>> reduced through addition of our foreign
<<73>> or inferior
<<74>> substances like for example orange oil
<<78>> yuzu and grapefruit oils are 99
<<82>> similar oils with each other
<<85>> but they have a huge price difference 20
<<88>> to
<<89>> 100 times and they are easy to mix as
<<92>> well
<<93>> certainly there is a huge aroma
<<96>> difference
<<97>> between yuzu orange and grapefruit oils
<<100>> mixing of lavending in lavender a mixing
<<103>> of geranium in rose oils etc etc
<<108>> how many types of essential oils are
<<111>> available in market
<<113>> on the daily basis i analyzed several
<<115>> companies oils
<<117>> and found following types of oils pure
<<121>> and natural essential oils are one of
<<123>> the most
<<125>> expensive commodities the price of
<<127>> commercial essential oil
<<129>> such as aggro road can cost more than
<<133>> 50 000 per kg so to make higher profit
<<137>> people all the time try to develop some
<<140>> advanced method
<<141>> on adulteration so that they can make
<<143>> more profit
<<145>> there are basically five types of
<<147>> essential oils
<<148>> sold as 100 pure natural organic
<<152>> essential oils
<<154>> and they are aroma enhanced essential
<<157>> oil
<<158>> some synthetic fragrance compounds are
<<160>> added in essential oil
<<162>> cheap essential oil mislabeled essential
<<165>> oil
<<167>> bitter orange oil is sold as grapefruit
<<169>> oils lemonade is sold as lavender
<<172>> condiment is sold as peppermint
<<175>> synthetically derived essential oil
<<178>> natural compounds are not only found in
<<180>> plant
<<181>> they can come from chemical processes
<<183>> too some oils were found to contain
<<186>> added nature identical synthetic
<<189>> molecule
<<190>> some companies oils had heavier
<<193>> percentages of the career oil
<<197>> on my market survey i have found in
<<199>> every more than 80 percent of commercial
<<203>> commercially sold essential oils are
<<205>> adulted by any means
<<209>> adulteration can happen in all possible
<<211>> points
<<213>> some distiller starts distilling
<<215>> essential oils with this spray of aroma
<<218>> chemicals
<<219>> so that they can increase the oil yield
<<221>> percentages
<<222>> some do also eat carrier oils in the
<<225>> production site
<<226>> but this type of adulteration happens in
<<228>> minimum quantity
<<230>> the price of essential oil remains same
<<233>> even though
<<234>> it comes from a long cena broker so what
<<236>> is stabilizing the price
<<238>> you will get the same price as the
<<241>> production price
<<242>> its adulteration
<<246>> and there that's that's the magic of you
<<247>> know establishing the price
<<249>> so lesser the traders more the chance
<<252>> your oils to be pure least likely
<<255>> happens with retailer labor
<<256>> to make more profit they were already
<<260>> cheated by their supplier because they
<<262>> are buying oils in cheaper price
<<264>> till now i have analyzed more than 50
<<266>> 000
<<268>> essential oils samples from various
<<270>> countries
<<271>> producers distillers and retailers
<<275>> here is a summary of few data from my
<<277>> past analysis
<<280>> those data are obtained from the sellers
<<281>> claiming their oils to be 100 pure
<<284>> and natural essential oil i have not
<<287>> covered all the analysis
<<289>> data points may not be sufficient for
<<291>> some countries however data are not
<<294>> encouraging to me i carried out
<<297>> lavender essential oil adulteration
<<299>> several times
<<301>> back in 2017 19 and 21.
<<304>> all three times carried market surveys
<<306>> sold me more than 80 percent
<<309>> commercially sold lavender oil is
<<311>> altered
<<312>> you can find those in published articles
<<316>> we also did more than 15 popular brand
<<318>> of essential oil from
<<319>> europe market they also had high
<<322>> quantities of
<<323>> adulteration pure essentials are
<<328>> way expensive since they are produced in
<<330>> low quantities
<<333>> with expensive herb material if you are
<<335>> hunting for
<<336>> cheaper essential oil he may get screwed
<<338>> in adulterated
<<340>> essential oil people like to smell
<<342>> synthetic fragrances
<<344>> understanding human psychology
<<346>> adulterated manipulate aroma
<<349>> by blending with fragrant chemicals
<<352>> there is no strict regulation by
<<354>> government body on federal level
<<356>> adulteration detection is not easy it
<<359>> needs lots of expertise and experience
<<362>> essential oil being a natural products
<<364>> chemistry keeps changing on
<<366>> to deliver consistency to the customer
<<369>> sometimes adulteration has to happen but
<<372>> most of the adulteration happens for
<<374>> economic motive in market most of the
<<377>> sellers claim their oils
<<378>> by gcms tested
<<382>> 100 pure and natural essential oil
<<385>> so and so on sometimes they try to sell
<<388>> cheaper
<<389>> essential oil in the name of expensive
<<391>> essential oil
<<392>> such as boswellia cirrata is sold as
<<396>> frankincense
<<397>> pestilencerata is an indian frankincense
<<400>> and has low price
<<402>> yes it is also frankincense but they
<<404>> don't clearly mention
<<406>> the botanical name in the bottle
<<408>> cinnamon oil
<<411>> for cassia since they say the same zen
<<414>> as cinnamon
<<415>> and their name is miss utilized to take
<<418>> advantages
<<419>> cinnamon bark is way expensive over leaf
<<422>> they do not clearly mention in the label
<<425>> plant parts
<<426>> once i bought cinnamon oil considering
<<428>> bark
<<429>> it turned out to be leaf chemistry and
<<432>> therabatic efficacies
<<434>> bark versus leaf is way different
<<438>> another example is globe bird oil is way
<<441>> expensive than
<<442>> leaf and stem so
<<444>> [Music]
<<445>> do not fall on globe world or
<<448>> before buying oil try to understand
<<450>> which plant part was used to make the
<<452>> oil
<<453>> it makes a lot of sense in benefits too
<<457>> uh like spike lavender lavendin
<<460>> are also sold as lavender but the true
<<463>> lavender is lavandula angustifolia
<<465>> which is way different therapeutic
<<468>> quality over them
<<471>> similarly peppermint corn mint
<<473>> experiment they are not only mint
<<475>> so cheaper mint is sold as expensive by
<<478>> not
<<479>> mentioning exact botanical name
<<482>> roars uranium oil is not roswell kananga
<<485>> is sold as ylang
<<486>> oil because they say the same botanical
<<488>> name and they are differentiated by
<<491>> their sub species only
<<494>> there are several level traps so every
<<497>> time when you buy oil make sure
<<499>> you are buying right oils of right
<<501>> botanical name
<<502>> correct plant part used
<<506>> know the distillation process country of
<<508>> origin
<<509>> and check the gcms reports
<<512>> and i am showing you some market example
<<516>> i bought a sandalwood essential oil from
<<518>> a four and a half
<<519>> you know close to five rated best
<<521>> sellers in amazon
<<523>> with more than 63 000 reviews
<<526>> and found that it was completely fake
<<530>> sandalwood essential oil 20
<<534>> per bottle of sandalwood which is kind
<<536>> of impossible
<<538>> they claim their product to be 100 pure
<<540>> and natural
<<541>> essential oil however the oils aroma
<<544>> was like a sandalwood aroma you can be
<<546>> easily duped
<<548>> if you are not experienced
<<551>> the aroma of sandalwood was caused by
<<553>> synthetic sandalwood fragrances
<<555>> they are way cheaper than true
<<557>> sandalwood
<<559>> there were no sandalwood components
<<561>> present in this sandalwood
<<562>> essentially you can see the gcms report
<<565>> so rating and claims are not always
<<569>> reliable
<<570>> tools for quality assessment
<<576>> you ever heard blueberry essential oil
<<579>> have you ever used there is nothing like
<<582>> blueberry essential oil in this universe
<<585>> when i saw this in amazon i ordered and
<<588>> tested
<<589>> it seems to be synthetic fragrances only
<<592>> but it was claimed to be hundred percent
<<594>> pure organic plant
<<596>> essential oil as you see in the picture
<<601>> frausulent products innocent consumers
<<604>> have been ripped up no one is taking
<<606>> responsibility for this
<<609>> dishonesty nowadays
<<612>> essential oil is available almost in in
<<615>> every store
<<616>> and surprises me how can they do quality
<<619>> control
<<620>> qc is the toughest part of essential oil
<<622>> trade
<<624>> i have sample collection hobby for
<<627>> testing alteration technique
<<629>> supermarket essential oil samples are
<<631>> more than
<<632>> 80 percent adulterated as with online
<<638>> and here is one bergamot sample i bought
<<641>> in
<<641>> whole food store and
<<644>> probably you know bergamot essentially
<<646>> is sold more than 12 times
<<648>> of actual production since bergamot
<<652>> farming is done
<<653>> just for essential oil production not
<<656>> much
<<656>> use of juices or byproducts like with
<<659>> other citrus product
<<661>> and bergamot is kind of king of the
<<663>> essential oil
<<664>> because it has properties of lavender
<<667>> lemon
<<668>> lime grapefruit all other different
<<671>> citrus oil
<<672>> i consider this might be one of the best
<<674>> oil and is in high demand
<<677>> on analyzing bergamot oil from whole
<<679>> food store
<<681>> some questions came up in my mind you
<<684>> can see the dcms report
<<686>> and you can see it was passing iso
<<688>> standard and it will pass
<<690>> chirality test and even c14 testing
<<693>> on the gcms test you can see yellow
<<695>> highlighted components
<<697>> such as pleniolicity a b c
<<700>> and d and linoleum oxide acetate c is
<<703>> transparent those are considered
<<705>> synthetic marker of
<<706>> linale acetate in bergamot essential oil
<<712>> and that clearly indicates linale
<<713>> acetate has been boosted on this
<<715>> bergamot sample
<<717>> this is one of the example of smart
<<720>> alteration
<<721>> ordinary lab and chemist will fail on
<<723>> identifying this type of sophisticated
<<726>> adulteration there are several natural
<<728>> claims cosmetic products
<<730>> out there in market and i tested them
<<733>> too
<<734>> none of them were my kind of more than
<<736>> 95 percent of them are not
<<738>> natural pure as was mentioned in the
<<742>> label
<<744>> they use synthetic harmful fragrances it
<<746>> can cause
<<748>> you know adverse effect rather any
<<750>> beneficial effect when you use product
<<751>> like this
<<753>> customer awareness is the most effective
<<756>> way to reject harmful synthetic
<<758>> fragrances
<<761>> there are samples these are samples i
<<764>> analyzed from india market none of them
<<767>> were pure
<<769>> absolutely fake nothing closer even to
<<772>> the you know real oils chemistry
<<775>> i'm surprised where is ethics to
<<777>> understand uses
<<778>> chemistry and safety we can follow those
<<781>> books you know they are very
<<783>> useful books
<<786>> market survey i did on birds essential
<<789>> oil
<<790>> out of all those analyzed birdswell none
<<793>> of them were true birds
<<795>> essential oil and we are publishing
<<796>> paper on this
<<798>> 70 percent of those oils were synthetic
<<801>> and rest of them were winter green or
<<804>> winter green mixed with synthetic methyl
<<806>> salicylate
<<808>> conclusion of this market research was
<<811>> there is no
<<812>> so called birds oil exist in the market
<<817>> most of the alteration is motivated for
<<820>> financial gain
<<823>> it has some serious consequences
<<826>> toxicity essentially used in
<<828>> aromatherapy
<<830>> sometimes adulterer oils contain toxic
<<832>> chemical that can have
<<833>> adverse effect on human health unfair
<<836>> competition the price difference of
<<839>> synthetic oil
<<840>> and natural oil production hues
<<843>> being the lack of awareness people are
<<845>> comparing the price of natural and
<<847>> synthetic and
<<848>> attracted to our synthetic oil because
<<850>> they smell great
<<852>> likewise there is unfair competition
<<854>> brought up by adulterated oil
<<857>> and it will impact on communities
<<858>> economy several poor farmers and their
<<861>> economies are dependent upon production
<<863>> of pure and natural essential oil
<<866>> if they have to drop their essential
<<868>> price to mess with synthetic
<<870>> market they are never going to get fair
<<873>> ways
<<874>> so this will impact on communities or
<<876>> the you know farmers economy
<<879>> as well as it will lower therapeutic
<<881>> values
<<882>> naturopathy is turning out to be
<<884>> syntheopathy
<<885>> so definitely it will not give the same
<<887>> benefit as
<<888>> natural is giving i
<<891>> imagine if this trends of adulteration
<<894>> remains
<<895>> continued on day for finding a pure
<<898>> and natural oils we need to visit to
<<901>> museums or it will be only in the story
<<906>> there is a lack of government regulation
<<908>> and proper analytical techniques
<<910>> that's the reason all adolescent
<<912>> adulteration is getting rampant
<<914>> what is the health impact of
<<915>> adulteration
<<918>> unexpected biological activities are
<<920>> shown by
<<921>> adulterated oils oil contains chiral
<<924>> molecules they exist in two form d
<<926>> and l or rnds as for example thalidomide
<<930>> medicines for pregnant humans durr
<<934>> reduces morning sickness but if yellow
<<937>> aureus is used
<<938>> it also it can also go it was causing
<<941>> birth defect
<<942>> that's why this medicine was banned
<<944>> because you know its counterpart
<<946>> was not doing the work
<<949>> molecule is the same but their peer can
<<950>> cause severe birth defects on human
<<953>> health
<<954>> similar things can happen with essential
<<956>> oil molecules like for d
<<957>> limonene can increase systolic blood
<<959>> pressure whereas yellow limonene only
<<961>> affects in alertness
<<963>> and every you know and once they do
<<965>> adulteration they
<<966>> put both enantiomer d and dl together
<<970>> and use a wrong enantiomer
<<973>> can cause different biological activity
<<977>> essential oil community is always
<<979>> challenged by
<<980>> four different and most common kind of
<<983>> adulteration
<<984>> synthetic or man-made they can be either
<<988>> derived from natural precursor
<<990>> or petrochemical based precursor by
<<992>> using various reagents
<<994>> naturally isolate compounds is converted
<<997>> into another aeroma chemical
<<999>> which is used as fillers in essential
<<1001>> oil
<<1002>> this is one of the analytically
<<1004>> challenging types of adulteration
<<1006>> and it is considered as one of the
<<1007>> sophisticated adulteration technique
<<1010>> like for example naturally offering
<<1012>> limonine from orange oil
<<1014>> can get converted to other aroma
<<1016>> chemicals such as turbine in furrow
<<1019>> and other courier oils
<<1022>> or cooking oil edison type of
<<1024>> adulteration is the
<<1026>> dumbest type of adulteration
<<1029>> adding non-volatile impurity which even
<<1031>> barely shows up
<<1032>> in the gcms testing another one is
<<1036>> essential component isolated or fraction
<<1040>> fractionally isolated component such as
<<1042>> usinol
<<1043>> one it's in your limonene or other will
<<1046>> be added to alternate
<<1048>> essential oil it is quite most
<<1050>> challenging type of adulteration from
<<1052>> analytical perspective
<<1055>> most sophisticated out of all is the
<<1057>> addition of similar oil such as
<<1059>> lavendin into lavender cone mint and
<<1062>> peppermint
<<1064>> orange into in a grapefruit etc since
<<1067>> they have
<<1068>> similar chemical profile because they
<<1070>> are
<<1071>> economical profitable and chemically
<<1074>> similar to
<<1076>> adulteration is getting advanced day by
<<1078>> day and perpetrator find
<<1080>> some new and advanced ways of
<<1084>> adulteration so to overcome all the
<<1086>> instrumental limitation
<<1088>> people use natural isolate or naturally
<<1090>> derived synthetic molecule
<<1092>> since it can pass all available testing
<<1094>> method
<<1096>> i have seen several companies invest
<<1097>> more time on their adult trading
<<1099>> technique
<<1101>> where they can make more money rather
<<1103>> investing farms
<<1104>> farmers and in agriculture
<<1108>> our technique for adulteration detection
<<1110>> is one of the unique technique
<<1111>> which is called marker based technique
<<1114>> or altered oils all the time has this
<<1116>> type of testing
<<1117>> not much research work has been done on
<<1120>> this
<<1120>> area that's why
<<1124>> i decided to get my doctoral research on
<<1127>> marker-based
<<1128>> essential oil adulteration
<<1132>> all of the adulteration detection
<<1134>> techniques have several limitations
<<1138>> gcms is one of the best method of
<<1142>> essential oil analysis if information
<<1145>> obtained from gcms
<<1147>> is properly interpreted with all
<<1149>> experienced chemist
<<1151>> adulteration detection could not be a
<<1152>> nightmare
<<1154>> most of the time people ask me what is
<<1156>> the difference between your lab and
<<1158>> their lab they do have the same
<<1159>> instrument
<<1160>> as you have we do not only have
<<1163>> cutting-edge instrument
<<1165>> but also have the advanced adulteration
<<1167>> detection tools
<<1168>> i have developed during my last 10 years
<<1172>> time period
<<1173>> my library of essential oil analysis is
<<1176>> the world's
<<1177>> probably largest library of essential
<<1179>> analysis
<<1180>> essential oil it contains more than 14
<<1183>> 000
<<1184>> essential oil components
<<1187>> we carefully observed synthetic marker
<<1189>> and biomarkers
<<1191>> during our analysis for each and every
<<1193>> batch of
<<1194>> doterra essential oil and some people
<<1197>> say the oil is iso standard
<<1200>> does iso or any standard matter
<<1205>> iso standard is all the time encouraging
<<1208>> people to adulterate
<<1209>> as you saw the example of bergamot
<<1211>> essential oil from whole foods
<<1214>> probably they were trying to make iss
<<1215>> standard and it was meeting eyes so even
<<1217>> though it was not pure
<<1219>> i talk a lot about marker
<<1222>> on my previous slides let me explain
<<1226>> what are they
<<1228>> particularly i classify marker into two
<<1230>> categories
<<1231>> biomarkers and synthetic marker
<<1234>> biomarkers are unique characteristics
<<1236>> molecule
<<1237>> of the individual oil which is
<<1239>> commercially unavailable
<<1240>> to adulterate oils if some addition is
<<1243>> happened
<<1244>> by a marker of unrelated oil appears or
<<1246>> biomarkers of the
<<1248>> adulterated oil disappears like for
<<1250>> example
<<1251>> if corn meat oil is
<<1255>> added in peppermint oil you will see low
<<1257>> burner floral low carbohydrate d
<<1259>> low methyl fluoride on peppermint corn
<<1261>> mint is a cheaper oil
<<1264>> oils have similar chemistry to
<<1266>> peppermint oil
<<1267>> but cornmeal does not have those
<<1269>> molecules
<<1272>> lowering of those molecule or
<<1273>> disappearance of those molecules
<<1276>> in any peppermint oil definitely
<<1277>> indicates adulteration
<<1279>> in peppermint oil so vertebral
<<1282>> fluorosarmactin d
<<1283>> and menthopiran are biomarker peppermint
<<1286>> essential oil the impurities of the
<<1290>> synthetic molecules are all
<<1291>> are called synthetic marker the
<<1293>> appearance of synthetic markers
<<1295>> in oils indicate adulteration
<<1298>> with synthetic chemicals like for
<<1299>> example synthetic glynol
<<1301>> if you added in any linoleum containing
<<1304>> oils
<<1304>> you will see the hydroline aloe as a
<<1306>> synthetic marker of the linoleum edison
<<1309>> which you do not see in any pure
<<1311>> essential oil
<<1313>> there are all the time stress quantities
<<1317>> it's all the time tricky to find those
<<1319>> marker we are
<<1321>> we are all the time involved in
<<1322>> discovering those proprietary techniques
<<1326>> and thank you
