DeFINITIONS AND STANDARDS FOR ESSENTIAL OILS

The QUOSENTIS online shops are able to guarantee and certify the following labels, names and specifications:

They are essential oils, absolute and concretely botanically and biochemically defined. This means that we know the botanical variety, and that we can define the chemical (or biochemical) composition.

They are essential, absolute and concrete oils whose chemical composition is known with precision, and for which we can guarantee the major constituent, for example:

• Menthol, the majority in mint essential oil,
• Puleol in the absolute of frangipani flowers containing mainly lupeol, or benzyl acetate in the concrete Sambac. 

This is the case of essential oils, absolute, concrete shops hosted by QUOSENTIS, all identified by their botanical varieties and their chemical compositions.

These are essential oils and extracts (absolute, concentrated, concrete, butters) guaranteed without adding other close extracts, such as:

• Add an essential oil of lavandin in an essential oil of lavender
• Adding essential oil of petitgrain sour orange in a neroli essential oil
• Addition of limonene ex-orange Brazil, in a pink grapefruit essential oil

These are essential oils and extracts (absolute, concentrated, concrete, butters) guaranteed without adding synthetic molecules, for example:

• Addition of synthetic linalool in a coriander essential oil
• Addition of phenyl-ethyl synthetic alcohol in Rose's absolute.

Or addition of product difficult to detect without extensive control, such as: Addition of Hercolyn D, triacetine, IDCA, to "weigh down" the essential oil, the concrete, or the absolute.

This designation guarantees that the natural extract has been the subject of numerous controls (mainly gas chromatography with FID and MS detection, density, refractive index, rotatory power, flash point, and in some cases HPLC, infrared or ultraviolet), and that the results obtained are consistent with the natural references of the profession.

The technical references to evaluate the previous guarantees are present in the following bibliographical references:

The 26 allergenic compounds identified by IFRA and identified by the European Directive 2003/15 / EC, are determined by GC / FID double column, according to an internal method.
