Soy candles are candles made from soy wax, which is a processed form of soybean oil. They are usually container candles because soy wax typically has a lower melting point than traditional waxes, but can also be made into pillar candles if certain additives are mixed into the soy wax. [1]
Soy wax is made by the full hydrogenation of soybean oil; [1] [2] chemically this gives a triglyceride, containing a high proportion of stearic acid. It is typically softer than paraffin wax and with a lower melting temperature, in most combinations. However, additives can raise this melting point to temperatures typical for paraffin-based candles. The melting point ranges from 49 to 82 degrees Celsius (120 to 179 degrees Fahrenheit), depending on the blend. [3] The density of soy wax is about 90% that of water or 0.9 g/ml. [4] This means nine pounds (144 oz) of wax will fill about ten 16-oz jars (160 fluid ounces of volume). Soy wax is available in flake and pellet form and has an off-white, opaque appearance. Its lower melting temperature can mean that candles will melt in hot weather. Since soy wax is usually used in container candles, this is not much of an issue. [5]
Some soy candles are made up of a blend of different waxes, including beeswax, paraffin, or palm wax. [6]

Sоу candles dіѕtrіbutе frаgrаnсеѕ and ѕсеntѕ slightly less than paraffin candles. Paraffin is usually added to make a 'soy blend' which allows for a better scent throw and works better in hotter weather conditions. Soy is often referred to as a superior wax in comparison to paraffin because it produces a cleaner and slower burning candle. [5] The low melting роіnt trаnѕlаtеѕ to сооlеr-burning, longer-lasting саndlеѕ in temperate areas.
Soy candles can also come with coconut wax as an additive because coconut wax is viewed as more sustainable and is softer than soy making for a larger melt pool and disbursement of scent.
Paraffin wax is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), and its boiling point is above 370 °C (698 °F). Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons.
Beeswax is a natural wax produced by honey bees of the genus Apis. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols.
A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time. Candles have been used for over two millennia around the world, and were a significant form of indoor lighting until the invention of other types of light sources. Although electric light has largely made candle use nonessential for illumination, candles are still commonly used for functional, symbolic and aesthetic purposes and in specific cultural and religious settings.
Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different types are produced by plants and animals and occur in petroleum.
Petroleum jelly, petrolatum, white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons, originally promoted as a topical ointment for its healing properties. Vaseline has been an American brand of petroleum jelly since 1870.
Surfboard wax is a formulation of natural and/or synthetic wax for application to the deck of a surfboard, bodyboard, or skimboard, to keep the surfer from slipping off the board when paddling out or riding a wave. It is also used to increase grip on the paddle of a surf kayak or dragon boat.
Wax play is a form of temperature play practiced in a BDSM context, in which wax from a candle is dripped onto a person's naked skin, in order to introduce a slight burning sensation to the skin.
Ski wax is a material applied to the bottom of snow runners, including skis, snowboards, and toboggans, to improve their coefficient of friction performance under varying snow conditions. The two main types of wax used on skis are glide waxes and grip waxes. They address kinetic friction—to be minimized with a glide wax—and static friction—to be achieved with a grip wax. Both types of wax are designed to be matched with the varying properties of snow, including crystal type and size, and moisture content of the snow surface, which vary with temperature and the temperature history of the snow. Glide wax is selected to minimize sliding friction for both alpine and cross-country skiing. Grip wax provides on-snow traction for cross-country skiers, as they stride forward using classic technique.
A votive candle or prayer candle is a small candle, typically white or beeswax yellow, intended to be burnt as a votive offering in an act of Christian prayer, especially within the Anglican, Lutheran, and Roman Catholic Christian denominations, among others. In Christianity, votive candles are commonplace in many churches, as well as home altars, and symbolize the "prayers the worshipper is offering for him or herself, or for other people." The size of a votive candle is often two inches tall by one and a half inches diameter, although other votive candles can be significantly taller and wider. In other religions, such as Hinduism and Buddhism, similar offerings exist, which include diyas and butter lamps.
Petroleum products are materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. Most petroleum is converted into petroleum products, which include several classes of fuels.
Ozokerite or ozocerite, archaically referred to as earthwax or earth wax, is a naturally occurring odoriferous mineral wax or paraffin found in many localities. Lacking a definite composition and crystalline structure, it is not considered a mineral but only a mineraloid. The name was coined from Greek elements Όζω ozο, to stink, and κηρός keros, wax.
Microcrystalline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. In contrast to the more familiar paraffin wax which contains mostly unbranched alkanes, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons. It is characterized by the fineness of its crystals in contrast to the larger crystal of paraffin wax. It consists of high molecular weight saturated aliphatic hydrocarbons. It is generally darker, more viscous, denser, tackier and more elastic than paraffin waxes, and has a higher molecular weight and melting point. The elastic and adhesive characteristics of microcrystalline waxes are related to the non-straight chain components which they contain. Typical microcrystalline wax crystal structure is small and thin, making them more flexible than paraffin wax. It is commonly used in cosmetic formulations.
Hot-melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is sticky when hot, and solidifies in a few seconds to one minute. Hot-melt adhesives can also be applied by dipping or spraying, and are popular with hobbyists and crafters both for affixing and as an inexpensive alternative to resin casting.
Candle making was developed independently in a number of countries around the world.
A candle wick or lamp wick is usually made of braided cotton that holds the flame of a candle or oil lamp. A candle wick works by capillary action, conveying ("wicking") the fuel to the flame. When the liquid fuel, typically melted candle wax, reaches the flame it then vaporizes and combusts. In other words, the wick brings the liquified wax up into the flame to burn. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, fire-resistance, and tethering.
A candle warmer is an electric warmer that melts a candle or scented wax to release its scent. The candle warmer shown is intended to be used with jar candles or candles in cups, not with taper candles or candles without containers large enough to accommodate all the melted wax. Some candle warmers have a built-in bowl in which the candle is placed.
Cheese analogues are products used as culinary replacements for cheese. They are usually products made by blending other fats or proteins and used in convenience foods. The category includes vegan cheeses as well as some dairy-containing products that do not qualify as traditional cheeses, such as processed cheese. These foods may be intended as replacements for cheese, as with vegan products, or as alternatives, as in the case of products used for salad bars and pizza-making, that may have other properties such as lower cholesterol content or different melting points that make them attractive to businesses.
A melting tank is a tank used by manufacturing companies to manufacture a variety of products.
Wax melters are devices used in the packaging and candle-making industries to melt wax.
Wax emulsions are stable mixtures of one or more waxes in water. Waxes and water are normally immiscible but can be brought together stably by the use of surfactants and a clever preparation process. Strictly speaking a wax emulsion should be called a wax dispersion since the wax is solid at room temperature. However, because the preparation takes place above the melting point of the wax, the actual process is called emulsification, hence the name wax emulsion. In praxis, wax dispersion is used for solvent based systems.
