Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Paraffin shopping experience:
1. Compare - without doubt the biggest advantage that the Paraffin offers shoppers today is the ability to compare thousands of Paraffin at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Paraffin? Wrong! If the Paraffin is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Paraffin then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Paraffin? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Paraffin and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Paraffin wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Paraffin then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Paraffin site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Paraffin, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Paraffin, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
Paraffin is a common name for a group of
alkane hydrocarbons with the general formula C
nH2
n+2, where
n is the number of carbon atoms. The simplest paraffin molecule is that of methane, CH4, a gas at room temperature. Heavier members of the series, such as that of
octane C8H18, appear as liquids at room temperature. The solid forms of paraffin, called
paraffin wax, are from the heaviest molecules from C20 to C40. Paraffin wax was identified by Carl Reichenbach in 1830.
Britannica 1911
Paraffin, or
paraffin hydrocarbon, is also the technical name for an alkane in general, but in most cases it refers specifically to a linear, or
normal alkane — whereas branched, or
isoalkanes are also called
isoparaffins. It is distinct from the fuel known in Britain and South Africa as
paraffin oil or just
paraffin, which is called kerosene in much of the U.S., Australia and New Zealand.
The name is derived from the Latin
parum (= barely) +
affinis with the meaning here of "lacking
electron affinity", or "lacking reactivity".
Physical and chemical properties
It is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 47 °C and 64 °C. It is insoluble in water, but soluble in diethyl ether,
benzene, and certain esters. Paraffin is unaffected by most common chemical
reagents, but
combustion readily.
Pure paraffin wax is an extremely good electrical
Electrical insulation, with an electrical
resistivity of between 10^{13} and 10^{17} Resistivity.{{cite web | last =

For casting of metal and other materials, "investment casting waxes" are used, in which the paraffin wax is combined with several other materials to obtain the desired properties. Paraffin wax is not much used to make original models for
casting, as it is relatively brittle at room temperature and usually cannot be cold-carved without excessive chipping and breaking. Soft, pliable waxes such as beeswax are preferred for these purposes.
In industrial uses, it is often useful to modify the crystal properties of the paraffin wax, typically by adding branching to the existing carbon backbone chain. The modification is usually done with additives, such as
Ethylene-vinyl acetate, microcrystalline wax, or forms of
polyethylene. The branched properties result in a modified paraffin with a higher viscosity, smaller crystalline structure, and modified functional properties.
Liquid paraffin
Mineral oil, a mixture of heavier alkanes, has a number of names, including nujol, adepsine oil, alboline, glymol, medicinal paraffin, saxol, or USP mineral oil. It is often used in
infrared spectroscopy, as it has a relatively uncomplicated IR spectrum. When the sample to be tested is made into a mull (a very thick solution), liquid paraffin is added so it can be spread on the disks to be tested.
Liquid paraffin (medicinal) is used to aid bowel movement in persons suffering chronic constipation; it passes through the
alimentary canal without itself being taken into the body, but it limits the amount of water removed from the
Human feces. In the food industry, where it may be called "wax", it can be used as a lubricant in mechanical mixing, applied to baking tins to ensure that loaves are easily released when cooked and as a coating for fruit or other items requiring a "shiny" appearance for sale.{{cite web| last =
