Compositional Analysis
of Kobashi Essential Oils

Doing what's necessary! Searching, finding, and enjoying. The adulterators are out there. Unfortunately most don't have a clue due to the complexity. Fortunately you don't have to worry about this. The challlenge is ours to deal with. :)

Neroli and a Jasmine sambac have been a disappointment, in the past, but just part of the job.

Sample name :JASMINUM SAMBAC Batch number :20216 EJASS Origin :CHINA Plant part :FLOWER Our reference :BX75 28, 15.21,


This is why the majority of suppliers are selling adulterated garbage to customers that don't have a clue. The majority of suppliers don't have a clue either. This is just the tip of the iceberg!

26, 14.27, LINALOOL, 31.02

What does PLINOL @ 0.01% mean? Well, Linalool in Jasmine Sambac is usually around 8%. The PLINOL shows that synthetic linalool was added and most likely about 23%.

Also the 39, 18.66, BENZYL ACETATE, 32.54 BENZYL ACETATE is usually around 9%, so most likely around 23% was added.


Sample name :DAIDAI CITRUS AURANTIUM AMARA Batch number :20208 DAIDAI OIL Origin :CHINA Plant part :FLOWER Our reference :BX74 26, 33.99, PLINOL, 0.04 24, 32.00, LINALOOL, 49.97 (most likely over 10% synthetic added.) 9, 12.55, LIMONENE, 21.33 ( most likely 6%  to 12% added)

Not going to look at this any more, waste of time!


These samples passed the GC/MS, but failed the Pesticide test.

We laugh and are appalled when we see what many 'oil and Aromatherpy' companies say and peddle.

New kobashi water filtration system

KobashiNew state of the art water filtration system.

Kobashi water comes from a spring aquifer 66m below
the pristine hills of higher Cotley surrounded by the
ancient oak forest (Dandyland wood) and Dartmoor National Park.

When you purchase Kobashi Products your money is reinvested
to improve our already premium quality.

We wanted the best water for Kobashi products and drinking.
The system cost over 14,000GBP and filters to 5 microns and although no bugs were found, we still use a UV filter to sterilize.

Scott At GC-Ms

Mass Spectrum HP MS 5972 quadrapole detector, GC 5890 and Auto Sampler

The main analysis on each oil is carried out using gas-chromatography / mass-spectroscopy (GC-MS).
This type of analysis gives information about the individual components of each oil, and their relative amounts. See below for more information.

The physical properties of each oil are also tested to ensure that they are within the expected range for each oil (e.g., density). GC-MS Analysis Component identification The different components of each oil are identified using the following databases;

1.) Comparison of the GC retention time with a retention time library.

a) Comparison of the mass spectrum with the Wiley275.L, Wiley7n.L, and HPCH1607.L mass spectra librarys, containing over 360 000 entries. )

Comparison with pure 'standards' for certain- components, especially unwanted contaminants such as phthalates.

2.) Cross-referencing with other oils.

3.) Comparison with published data on each essential oil

4.) Analysis run on quantified library of pesticides to PPT accuracy. ppm = parts per million

1 ppm = 1/1,000,000 = 0.000001 = 0.0001%
10 ppm = 10/1,000,000 = 0.00001 = 0.001%
100 ppm = 100/1,000,000 = 0.0001 = 0.01%
200 ppm = 200/1,000,000 = 0.0002 = 0.02%
