Rose Extract
What does 20/40 when looking at distillation equipment?
I want to buy some lab scale distillation or solvent extraction kit to distil/extract essential oils from lemon peel, rose petals, cinnamon bark and wondered what 20/40 meant as I have seen this often in E-Bay listings.
It’s the size of the ground glass joint. The first number is the outer diameter (in mm) at the base of the joint (where it’s the largest) and the second number is the length of the joint.
So when you built your distillation kit, when you want to connect two pieces you will need a male and female joint of the same diameter and ideally the same length.

How Roses are Turned Into Oil for Perfume-producing Rose Oil
One of the most popular scents for perfume is the scent of real roses. Traditionally it is believed that Arab chemists were the first to find a way to produce useable perfume oils from roses. Rose oil commands a very high price, because it is so laborious to extract. The harvesting of the buds is done by hand before sunrise and the petals are used to create oil and scent extracts the very same day. It takes many pounds of rose petals to make just one ounce of oil. So how is the rose scent used in perfume created?
There are three current methods of getting oil out of the rose petals.
-
Extraction by a solvent -
Extraction by steam distilling -
Extraction via superficial carbon dioxide
In the solvent extraction method the rose petals are mixed in a vat or tub with some kind of solvent like hexane. The hexane draws out the rose aroma, as well as some wax and pigments. A vacuum process removes the Hexane and leaves a thick wax-like mass which is called Concrete in the perfume industry. Alcohol is put through the Concrete which draws out the scent part only. This alcohol mixture is then evaporated under low pressure, leaving the pure scent extract behind. This is called Rose Absolute and is an amber yellow to deep red in color. This is the least expensive method of scent extraction.
Removing rose scents by steam distilling involves large stills filled with rose petals and water. The still is heated for a period of time, until the water vapor along with rose oil vaporizes out of the still and into a condenser, where the condensate is run off into a container. Then the water is drained off from the oil leaving very concentrated oil. The drained off water is then re-distilled to extract water soluble oils or alcohols that still exist in the water. There is also a method to perform a combination distillation-extraction of this left over water. These water soluble constituents are mixed with the original concentrated oil to get the final oil product called Rose Otto or Attar. Rose Otto is made up of around 20% of the concentrated oil and 80% of the water soluble products. It is then diluted heavily when used in perfume. It is pale yellow to olive green in color and will crystallize at room temperature. Bulgaria is the largest producer of Rose Otto.
The carbon dioxide extraction method is the most expensive method of the three and the price of your perfume may reflect that. Carbon dioxide, which is normally a gas at normal pressures, is put under pressure until it liquefies. The Rose petals are mixed with liquid carbon dioxide and heated at very low temperatures. The rest of the process is similar to the standard solvent extraction method. When normal pressure is restored to the carbon dioxide it turns back into gas and leaves the aroma extracts behind. The CO2 does not leave any odor of its own behind.
A good deal of quality control must follow the process of making and buying pure rose oils as it is not unusual for it to be unscrupulously diluted with essential oils from the Geranium flower or Palmarosa herb (related to the Geranium), or even other alcohol related chemicals.

Does the following listing provide and efficient body cleansing or “detox”?
Does the following listing provide and efficient body cleansing or “detox”?
Buckthorn bark, triphala powder(amla, chebulic, myrobalan, belleric myrobalan) acidolphilus bifidus, fennel seed, foenugreek powder, papaya, ginger extract, barberry root, celery powder, peppermint, rose hips.
The ingredients are combined in a pill, but I want to know if it will “detox” the liver, kidney, and muscles?
Thats a really strange and large combination.
You didnt say specifically what your health concern is but in general it is best to avoid products that are heavily advertised over the net eg:products specifically saying things like Acaicleanse or detox formula etc.Some are ok but some arnt,so best to avoid things like you find at the first couple of entries of google(paid ads) or things which have free trials or credit card offers/autoship.
Its best to see a N.d/Naturopath/Herbalist or at least purchase from companies that are health/herbal interested & have good quality standards & know about herbs and not just profit focused.
Briefly-
Buckthorn bark used as laxative.
↓Triphala=G.I disorders,liver disorders.

Acidophilus bifidus is a probiotic for good bacteria.
Fennel seed is used for gas,increasing breast milk.
Fenugreek is used for lowering triglycerides amongst other things.
Papaya is used for enzymes.
Ginger for some types of nausea and rheumatoid arthritis.
European Barberry is used for kidneys,antimicrobial etc.
Celery powder for diuretic,arthritis,potassium,blood pressure.
Peppermint is used for sore throat,headaches,IBS etc.
Rose Hips i dont find much value in personally.
They are also used for other things too.
This tablet i dont find a well thought out formula with just different things thrown in together like a bad recipe.
