It is distinct from the fuel known in Britain as paraffin oil or just paraffin, which is called kerosene in American English. Usage of the term varies in other countries, leading to confusion about which substance is being referred to. The solid forms of paraffin are called paraffin wax. Paraffin is also a 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. The name is derived from the Latin parum (= barely) + affinis with the meaning here of "lacking 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 ether, benzene, and certain esters. Paraffin is unaffected by most common chemical reagents, but burns readily.
Pure paraffin is an extremely good electrical insulator, with an electrical resistivity of 1017 ohm meter. This is better than nearly all other materials except some plastics (notably teflon).
Liquid paraffin
Liquid paraffin has a number of names, including nujol, mineral spirits, adepsine oil, alboline, glymol, liquid paraffin, 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 is also excellent for helping bowel movement in persons suffering chronic constipation.
Uses
Candlemaking;
Coatings for waxed paper or cloth.;
Food-grade paraffin wax
is used in some candies to make them look shiny. Although edible, it is nondigestible; it passes right through the body without being broken down.;
Non-food grade paraffin wax can contain oils and other impurities which may be toxic or harmful.;
Magic Shell;
Coating for many kinds of hard cheese, like Edam cheese.;
Sealing jars, cans, and bottles.;
;
A key component in wax used for investment casting.;
As anti-caking, moisture repellent, and dustbinding coatings for fertilizers.;
Preparing specimens for histology.;
Solid propellant for hybrid rocket motors.;
In dermatology, as an emollient (moisturiser).;
Surfing, for grip on surfboards as a component of surfwax.;
The primary component of glide wax, used on skis and snowboards.;
For use on handrails and cement ledges to dramatically reduce friction for rolling, otherwise known as aggressive in-line skating.;
Microwax as a food additive, a glazing agent with E number E905.;
The paraffin test is used in forensics to detect granules of gunpowder in the hand of a shooting suspect.;
A fire performance fuel.;
Blends of paraffin and micro waxes in rubber compounds as anti-ozonant agent, to prevent cracking of the rubber. The antiozonant waxes can today be produced from synthetic waxes, FT wax, and Fischer Tropsch wax.;
"Potting" guitar pickups, which reduce microphonic feedback caused from the subtle movements of the pole pieces;
Paraffin, being rich in hydrogen, is used in some experiments with neutrons.;
