<<0>> Hello, my name is Minas, I am the
<<2>> production manager here at doTERRA
<<4>> Ireland. I would like to introduce you to one of
<<6>> our leading chemists on site,
<<7>> my colleague Kelly, who is here with us
<<11>> today. So, for those who didn't
<<12>> hear, our newest facility
<<15>> was opened in October 2020, and our
<<17>> goal is to produce over 90
<<20>> different oils for the European
<<21>> market by the end of 2021.
<<22>> However, we don't just have a
<<23>> production facility in Ireland; we
<<25>> also have a laboratory to monitor
<<27>> quality, and that is an important
<<28>> aspect. Yes, we even have a laboratory
<<31>> that is state-of-the-art,
<<33>> right here on site, which
<<34>> is further divided into two areas:
<<35>> a chemical and a micro-
<<38>> microbiological laboratory. We test everything
<<40>> that comes here, from raw materials when they
<<43>> first arrive for a blend, to the
<<45>> finished product, ensuring the purity of the
<<47>> oil throughout its entire life cycle.
<<50>> We perform various tests on
<<52>> site, including analytical tests like HPLC,
<<55>> GC-MS, ICP. For all of them, we use the
<<58>> mass detector, which improves sensitivity
<<60>> and therefore our results.
<<61>> After that, we perform concentration and
<<63>> purity tests. These include
<<66>> refractive index, optical rotation, and
<<68>> specific gravity, and we do our FTIR
<<70>> tests, which are all FTIR, and
<<73>> organoleptic tests, and we will now describe them
<<75>> in detail. The organoleptic tests
<<78>> are divided into three tests, so we have
<<80>> appearance, color, and smell. Yes, we have two samples here, and I
<<84>> have covered the labels.
<<86>> One was purchased online, and the
<<90>> other is one of our oils.
<<92>> Okay, so the first test we perform
<<95>> is for appearance. The idea is that we
<<97>> have specifications for all of our oils.
<<98>> Therefore, for this specific oil,
<<100>> the standard says it should be a semi-opaque,
<<103>> mobile liquid. So,
<<105>> the first thing we do when you take it here
<<107>> out of the holder is hold it
<<109>> against this white paper to
<<110>> ensure there are no particles or anything.
<<112>> Well, yes, it is clear, semi-opaque, with
<<116>> a good viscosity. Next is the color.
<<119>>
<<120>> According to the specs for this oil,
<<123>> it says it can be pale to light yellow.
<<125>> What do you see? It looks like it is
<<129>> very, very light yellow. Next is
<<132>> smell. Smell is one of the
<<135>> most important characteristics.
<<136>> So what we do is waft it towards
<<138>> the nose and check if it is the oil it
<<141>> should be. This is delicate and lingers.
<<144>> And even when I move it away, I can
<<147>> still smell it on my palate.
<<149>> Okay, does that make sense? No, that's good,
<<151>> it's good. Yes, it's good, so I won't say
<<155>> anything until we have compared it with the other one.
<<157>> That is sample B, yes.
<<159>> So, appearance again: it should be a
<<161>> semi-opaque, mobile liquid.
<<164>> It looks similar to the first sample. Is it
<<167>> semi-opaque and mobile? Perfect. Then
<<170>> color-wise, it is similar again, maybe slightly
<<172>> lighter, but similar. Okay, now the smell.
<<176>> So, waft it towards the nose again.
<<182>> That is quite sharp and intense,
<<186>> but it disappears, it disappears
<<187>> very quickly now, as if it has completely
<<189>> vanished. Okay, yes, if you bring the
<<191>> two together so that you
<<194>> can see the difference side-by-side,
<<195>> looking at the color, the semi-opaque,
<<197>> mobile liquid, the sample
<<200>> here on my right is slightly darker.
<<202>> Yes, both are mobile, yes, but I
<<205>> think that is one of the main factors to
<<208>> recognize whether an oil is natural or
<<209>> synthetic. Both look very similar,
<<211>> but the main difference is the
<<213>> smell. With a natural product, you know
<<216>> the oil is a bit soft when
<<218>> it first reaches the nose,
<<220>> and the smell lingers; the smell
<<222>> remains in the nose for a while afterward.
<<224>> With synthetic oil,
<<227>> on the other hand, you get a sharp,
<<229>> intense smell that you notice immediately,
<<231>> but it disappears just as quickly as
<<234>> you noticed it. That is the
<<236>> main difference between a
<<237>> synthetic and a natural oil.
<<239>> Visually, they are identical; without
<<242>> further testing, it is difficult to tell
<<243>> the difference, which one is actually
<<245>> pure and which is synthetically produced.
<<247>>
<<251>> After the organoleptic test, the next
<<255>> test we perform is to
<<256>> identify and quantify molecular compounds.
<<260>>
<<261>> In simple terms, an identity
<<263>> test is like a fingerprint. Yes, very much like
<<265>> a fingerprint, exactly. What happens
<<267>> when you have the equipment is you
<<269>> place the oil on the prism, and the infrared
<<272>> light passes through it and hits
<<276>> the detector, and then a
<<277>> unique fingerprint spectrum is created for
<<279>> these components. So, every
<<281>> different component in the oil has its
<<283>> own spectrum. Can we tell this way
<<285>> which oil is pure and which is not?
<<286>> Yes, that's how you find out, and there is a standard for all
<<289>> of our oils. For example, if we
<<292>> take a Lavender (Lavender) oil,
<<293>> we have the standard
<<295>> available. The sample of the Lavender (Lavender) must
<<297>> match the standard by 95% or more.
<<299>> So, we tested both oils using FTIR.
<<302>> The result was: for our own
<<305>> Lavender (Lavender) oil, we got 99%
<<307>> back. The purchased oil, I can't
<<310>> find even the slightest match for Lavender (Lavender),
<<312>> even though we purchased it as
<<314>> Lavender (Lavender) oil. We had bought a
<<316>> Lavender (Lavender) oil. That's interesting, yes. It
<<319>> does not correspond in any way to our
<<321>> Lavender (Lavender), which is unusual
<<323>> if only one petroleum product was detected, and
<<326>> the other is a mixture, which suggests
<<328>> that the other oil is a combination
<<330>> of many other substances, as opposed
<<332>> to simple Lavender (Lavender) oil. Very
<<333>> interesting.
<<338>> After finding out that it was not what
<<340>> we expected, the next test
<<342>> would be a GC-MS.
<<344>> GC-MS is an abbreviation for
<<347>> gas chromatography. What a GC-MS does is
<<350>> identify individual components of a sample.
<<352>> Now we know for sure it doesn't match,
<<354>> and it doesn't match the Lavender (Lavender) standard.
<<357>> The next
<<358>> step is to determine exactly
<<360>> which components it is
<<362>> composed of. Okay, GC-MS
<<364>> consists of two steps. We have
<<366>> the stationary phase and the mobile
<<369>> phase. The stationary phase is in the column.
<<373>> For our test, we use helium. We
<<375>> inject the oil into the column, the gas moves
<<378>> the sample through the column to the
<<379>> detector, and then the detector prints out a
<<382>> chromatogram. These are
<<386>> two results we got from the oils.
<<389>> The peaks are all the components present in the oil.
<<392>> Here, there is a specific
<<394>> peak you can see; it is
<<396>> isopropyl alcohol. It is not in our oil, but
<<401>> in the synthetic one, and not
<<403>> in our natural oil. That is a major
<<405>> indicator to know whether an oil is
<<407>> natural or has been synthetically, chemically modified.
<<409>> This peak here
<<411>> is one of them, isopropyl alcohol. It
<<414>> is widely used in the
<<416>> cosmetics industry, in medicine, for example,
<<418>> surface treatment, where rapid absorption
<<420>> is desired. So it is added
<<423>> chemically. As you can see, it makes up
<<425>> a large amount, and I think
<<428>> in this synthetic oil, you are buying 40%
<<429>> alcohol instead of Lavender (Lavender). In our
<<432>> oil, it is of course not present
<<433>> because it is 100% pure.
<<436>> Why do we go to all this trouble?
<<438>> Why is quality control so important? It is
<<440>> very important for any successful
<<441>> company to guarantee quality
<<442>> and ensure that products going to
<<446>> our customers meet and even
<<448>> exceed their expectations.
<<450>> Quality controls are there to
<<452>> guarantee safety and high
<<454>> efficacy. This gives us the
<<456>> confidence to know that the oils and
<<458>> products reaching our customers are of the
<<460>> highest quality out there, and
<<462>> we are proud of that. Well, Kelly, I
<<465>> must thank you. It was very helpful
<<467>> that you, as our lead chemist here on site,
<<468>> explained some of the tests that
<<471>> are necessary, why we perform them,
<<472>> and what that means not only for
<<475>> us, but also for our customers in the field.
