What are ‘Florasols’?

“Many flowers, plants and herbs are to delicate to withstand the rigours of steam distillation, and therefore other methods of extraction must be used, ‘Florasols’ are extracted by using a harmless, low-boiling refrigerant gas that captures more of the plants components and produces a fragrance, aroma or flavour more true to nature.”

‘FLORASOLS’ are exquisite, pure, natural oils prepared from the finest quality plant material.

‘FLORASOLS’ are never heated above room temperature (as are distilled oils), never exposed to acids (as are ‘SCFE’ oils), and are complete with all their volatile / fragrant ingredients and with all their natural active components. They are never ‘stripped’ (as are ‘concretes’ and ‘absolutes’).

‘FLORASOLS’ are prepared under anaerobic conditions. No oxidation of fragile components can occur.

The quality of ‘FLORASOLS’ is approved by many major pharmaceutical companies and do not use alcohol in the process. ‘FLORASOLS’ are not exposed to oxygen and the resultant oils are ‘as nature intended’. They are entirely free from hexane or chlorinated solvents or other toxic residues and are sterile, pathogen free; contain no E. Salmonella, no Listeria, no ‘aphlatoxins’. Oil produced by our process is approved by European Commission ‘Food Safety Committee’ and the European Parliament as being safe for use as food flavours.

Our revolutionary HFC 134a process

uses refrigerant-based solvents (1,1,1,2 – tetrafluoroethane) as the extraction solvent.

Is very gentle (So gentle that some seeds are still alive after extraction and can be geminated)

Is a fully sealed process – so it does not allow emission into the environment

Does not use toxic solvents

 Is not hazardous

Requires VERY little energy

 Use no water

Is economical to operates

Re-cycles its resources

Use no acids – it is pH neutral

Extracts no waxes, no fats, no ‘water’

Produces no effluent

“The most environmentally friendly way of preparing fine, pure, natural oils from plants.”

‘FLORASOLS’ are oils, produced using the revolutionary method of oil extraction invented in the late 1980s and further developed by Dr. Peter Wilde B.Sc., Ph.D., F.R.I.C., F.L.S., as a new generation of plant oils of the very highest quality.

‘FLORASOLS’ are far superior to their more traditional counterparts. To understand the nature of these products, it is first necessary to look what they are not …

‘Florasols’ Are NOT ‘Essential Oils’! Why?

‘Essential’ oils are made by steam or water distillation. The plant material is boiled for several hours in a kettle with lots of water (typically three times its weight). Some of the water turns to steam which carries the fragrant oil with it. The steam is condensed back to water by cooling it in condensers. The ‘essential’ oil floats on the surface of the condensed water and is skimmed off. So, ‘essential oil’ has all been COOKED. Heat will have damaged and changed many of the fragile, naturally occurring substances. Much of the most delicate, fragrant, light, volatile components will have been lost during the condensation. Much of the fragrant is also lost – dissolved in the condensed waters (rose water is a fragrant!), this loss have been at the expense of the oil. This process uses huge amounts of fossil fuel to boil the plant/water mix, pollutes, and also produces vast quantities of boiling hot liquid waste.

‘Florasols’ Are NOT ‘Concretes’! Why?

‘Concretes’ are made by stirring up vegetable matter with hexane (gasoline) or chlorinated solvents (such as methylene chloride). Hexane dissolves (extracts) many of the plant’s components. The hexane solution is then evaporated to dryness at 750 Celsius. The ‘concrete’ is what it’s left, after the hexane has been driven off/boiled away. So, ‘concretes’ have also been heated. They also contain residual hexane. They contain about 50% of the plant’s waxes, pigments, resins, fats, (triglycerides and fatty acids) and sterols and their esters. Heating will have caused damage to the fragile components and the loss of their delicate ‘volatiles, particularly if the hexane has been removed under high vacuum (which is usual practice) hexane is lost into the atmosphere where it is a serious ‘Volatile Organic Compound’ – VOC pollutant, contributing to toxic. Needless to say, the process is also extremely hazardous as hydrocarbons are all flammable.

We can however extract from Concretes using our HFC Process and, in this case, we first coat the Concrete onto a carrier medium and then extract using the normal ‘FLORASOLS’ process. The extraction time will be longer than a standard extraction, but the yield will of cause be proportionally higher as the concentration of the oil in the Concrete is higher also. As an example; 1kg of Rose Concrete may produce 500 Gms of oil whereas 1 kg of Rose will provide 1 Gm of oil.

‘Florasols’ Are NOT ‘Absolutes’! Why?

‘Absolutes’ are made from ‘concretes’ by milling them with 98% alcohol. Strong alcohol dissolves the ‘absolutes’ out of the buttery mass of ‘concretes’. This alcohol solution is frozen to – minus 100 Celsius (14 degrees Fahrenheit), which precipitates the waxes. This cold solution is filtered and the filtrate/solution concentrated by rigorously boiling off of the alcohol under vacuum. The ‘absolutes’ is the oil which is left after the alcohol has been boiled away. Alcohol boils at 78Celsius. So “absolutes’ have been through TWO ‘boiling-off’ processes (the first from hexane, the second from alcohol), Volatile fragrant components will have been stripped out and lost and damage will have been done to the delicate heat sensitive components of the oil on both occasions.

 ‘Florasols’ Are NOT ‘SCFE Oil’! Why?

Warm carbon dioxide gas at exceeding high pressure can be used to dissolve fragrant/flavour oils from some plant materials. The acidic gas, carbon dioxide, is passed through the warm plant material at 300 – 500 times the pressure of the atmosphere (pressure such as those found in the nature at the bottom of the Pacific Ocean, three miles down!) -  don’t try this at home! This ‘fluid’ dissolves oil, resins and waxes out of the plant material. When the pressure is allowed to fall to only 100 ‘Bar’ (=100 time atmospheric pressure, the oil form into a mist and can be collected. Needless to say, the equipment needed for this process is massive in the extreme and VERY costly and uses huge quantities of electricity to drive it. This is why products are so expensive. The effect of the high degree (all low as pH 2.0) at these temperatures on the ‘naturalness’ of SCFE products, will reward further study.
