Soft and pliable waxes, like beeswax, may be preferred for such sculpture, but " investment casting waxes," often paraffin-based, are expressly formulated for the purpose. In a histology or pathology laboratory, paraffin wax is used to impregnate tissue prior to sectioning thin samples of tissue.
Why is paraffin wax important?
Paraffin represented a major advance in the candlemaking industry because it burned cleanly and reliably and was cheaper to manufacture than any other candle fuel. Paraffin wax initially suffered from a low melting point; however, this shortcoming was later remedied by the addition of harder stearic acid.
How much paraffin is safe to use?
The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) for paraffin wax fume exposure of 2 mg/m 3 over an 8-hour workday.
What is the product wax called?
After the solvent is recovered by distillation, the resulting products are called "product wax" (or "press wax ") and "foots oil". The lower the percentage of oil in the wax, the more refined it is considered (semi-refined versus fully refined). The product wax may be further processed to remove colors and odors.
When was paraffin wax invented?
Paraffin wax was first created in 1830 by the German chemist Karl von Reichenbach when he tried to develop the means to efficiently separate and refine the waxy substances naturally occurring in petroleum. Paraffin represented a major advance in the candlemaking industry because it burned cleanly and reliably and was cheaper to manufacture than any other candle fuel. Paraffin wax initially suffered from a low melting point; however, this shortcoming was later remedied by the addition of harder stearic acid. The production of paraffin wax enjoyed a boom in the early 20th century as a result of the growth of the oil and meatpacking industries which created paraffin and stearic acid as byproducts.
What is the melting point of paraffin wax?
Paraffin wax is a white, odorless solid with a typical melting point between approximately 115 and 154 °F (46 and 68 °C) having a density of approximately 0.9 g/cm 3. Wax has low thermal conductivity, a high heat capacity, and is insoluble in water.
What is paraffin wax?
Paraffin wax is a white or colorless soft, solid wax that is composed of a complex mixture of hydrocarbon derivatives with the following general properties: (i) nonreactive, (ii) nontoxic, (iii) water barrier, and (iv) colorless. Paraffin wax is characterized by a clearly defined crystal structure and has the tendency to be hard and brittle with a melting point typically in the range 50–70°C (122–158°F). On a more specific basis, petroleum wax is of two general types: (i) paraffin wax in crude oil distillates and (ii) microcrystalline wax in crude oil residua. The melting point of wax is not directly related to its boiling point because waxes contain hydrocarbon derivatives of different chemical nature. Nevertheless, waxes are graded according to their melting point and oil content.
What is petroleum wax?
On a more specific basis, petroleum wax is of two general types: (i) paraffin wax in crude oil distillates and (ii) microcrystalline wax in crude oil residua. The melting point of wax is not directly related to its boiling point because waxes contain hydrocarbon derivatives of different chemical nature.
How is paraffin wax obtained?
Paraffin wax is usually obtained by dewaxing refined lubricating oil stocks. Dewaxing processes usually employ a combination of chilling, filtration, and extraction by suitable solvents such as MEK or MIBK. Soft wax is obtained at the preliminary dewaxing stages and, therefore, contains some residual quantities of oil.
How is wax dissolved in a pipeline?
Wax, paraffin, or sulfur deposits in an oil or gas pipeline can be dissolved by addition of a compound which liberates carbon disulfide on contact with acid. Thereby the deposit is dissolved by the liberated carbon disulfide [ 20 ].
Is paraffin wax a hydrocarbon?
Although many natural waxes contain esters, paraffin waxes are hydrocarbon derivatives, mixtures of alkane derivatives usually in a homologous series of chain lengths. These materials represent a significant fraction of crude oil and are refined by vacuum distillation.
Is paraffin wax a liquid?
Paraffin wax is a solid crystalline mixture of straight-chain (normal) hydrocarbons ranging from C20 to C 30 and possibly higher, that is, CH 3 (CH 2) n CH 3 where n ≥ 18. It is distinguished by its solid state at ordinary temperatures (25°C, 77°F) and low viscosity (35–45 SUS at 99°C, 210°F) when melted. However, in contrast to petroleum wax, petrolatum ( petroleum jelly ), although solid at ordinary temperatures, does in fact contain both solid and liquid hydrocarbons. It is essentially a low-melting, ductile, microcrystalline wax.
How to melt paraffin wax at home?
If you have nail polish on, remove it before starting the process. Wash your hands well and dry them with a lint-free towel. To melt the wax: Add four pounds of paraffin wax to the top of a double boiler.
What is paraffin wax?
Paraffin wax is a white or colorless soft, solid wax. It’s made from saturated hydrocarbons. It’s often used in skin-softening salon and spa treatments on the hands, cuticles, and feet because it’s colorless, tasteless, and odorless. It can also be used to provide pain relief to sore joints and muscles. Paraffin wax has many other uses, too.
How to make wax from a wax boiler?
Add water to the bottom of the boiler and place it on the stove over low heat. Add one cup of mineral oil to the wax. When the wax is completely melted, take the boiler off the stove. Carefully pour the wax into a greased plastic container. Wait for a thin skin to form on the top of the wax.
How much does a paraffin wax bath cost?
The cost of a paraffin wax treatment varies greatly by salon, starting from around $15. It generally takes around 30 minutes.
Why does paraffin wax make you swell?
If you have a chemical sensitivity , you may develop minor swelling or breakouts from the wax treatment. That’s because paraffin comes from petroleum products. If you’re doing a paraffin wax treatment at home, take care not to heat the wax too much, as it may catch fire.
How long does it take to remove wax from your hand?
After 15 to 20 minutes, remove your hand from the mitt or towel and the plastic bag. Use soft tissue to remove the wax residue from your skin. Apply moisturizer all over your hand.
How long to put wax on foot?
Then place it in an oven mitt or wrap it in a towel for 15 to 20 minutes.
Overview
Properties
Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m . It is insoluble in water, but soluble in ether, benzene, and certain esters. Paraffin is unaffected by most common chemical reagents but burns readily. Its heat of combustion is 42 MJ/kg.

Manufacturing
The feedstock for paraffin is slack wax, which is a mixture of oil and wax, a byproduct from the refining of lubricating oil.
The first step in making paraffin wax is to remove the oil (de-oiling or de-waxing) from the slack wax. The oil is separated by crystallization. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled. As it cools, wax crystallizes out of the sol…
Applications
In industrial applications, 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 EVA copolymers, 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. Pure paraffin wax is rarely used for carving origina…
Occupational safety
People can be exposed to paraffin in the workplace by breathing it in, skin contact, and eye contact. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) for paraffin wax fume exposure of 2 mg/m over an 8-hour workday.
