Is paraffin a good candle wax?
Updated
On this page7
Yes, for many candles. Paraffin is a refined petroleum wax sold in grades from soft container waxes to hard pillar waxes, used in pillars, votives, tapers, jars and many blends, and one large supplier chooses it for containers for its vivid color and fragrance throw. Its melt range is wide: FAO puts most paraffin waxes between 48 and 68°C (118 to 154°F), so the grade you buy decides what you can make. This page explains how paraffin grades differ, how to read a paraffin specification, why it is used in pillars and blends, and what the evidence says about the health claims made against it.
What paraffin is, and why grade matters more than the name
Paraffin wax is a petroleum product, de-oiled and purified to the degree its intended use requires. What a candle maker buys is never just "paraffin." It is a grade defined by a few measured properties, and two grades can behave as differently as soy and beeswax.
The wide range FAO gives for paraffins, 48 to 68°C [1], spans container waxes at the low end and pillar waxes at the high end. The additive maker NuCera draws the line in its VYBAR literature at 58°C: it recommends one set of its polymers for paraffins melting at or above 58°C, used in "columns, pillars, tapers, freestanding decorative and votive candles," and another for paraffins melting below 58°C, used in container, votive and tart candles [2]. That is one supplier's dividing line, but it matches the general rule that freestanding candles need a harder, higher-melting wax.
Reading a paraffin specification
Here is what one paraffin seller publishes for a fully refined grade sold for candles. The figures are DistrEbution GmbH's, from its product specification dated April 28, 2026 [3].
| Property on the sheet | Value for this grade | What it tells you |
|---|---|---|
| Solidification point | 56 to 58°C (133 to 136°F) | The temperature at which the cooling wax sets. Also called the congealing point. Sellers often name the grade by it. |
| Melting point | 58 to 60°C (136 to 140°F) | Where the solid wax turns liquid. It sits just above the solidification point. |
| Oil content | 0.75 percent or less by mass | How much liquid oil remains in the wax. Lower oil generally means a harder, drier wax. |
| Needle penetration at 25°C | 19 or less (tenths of a millimeter) | Hardness. A needle pushed into the wax under a set load sinks less into a harder wax. |
| Color (Saybolt) | 27 or higher | Whiteness. Higher numbers are paler. |
| Light stability | 4 or less | Resistance to yellowing in light. |
| Stated uses | Industrial application, candle manufacturing, use as a component | The seller's intended uses. It gives no pour temperature or wick; the sheet says each use must be tested. |
The same seller lists a 54 to 56°C solidification grade with a melting range of 50 to 60°C and oil content "less than 0.8%," described as easily mixed with fragrances, stearines and other waxes [4]. The sheet for one grade does not describe the next.
Fully refined and semi-refined
"Fully refined" means the wax has been de-oiled and purified to a low oil content; both DistrEbution grades above are sold as fully refined with oil content below 0.8 percent [3][4]. Semi-refined grades carry more oil, which makes them softer and more prone to oil on the surface. None of the candle data sheets cited here gives an oil figure for a semi-refined grade, so none is stated here. If a supplier sells "paraffin" without saying whether it is fully refined and without an oil content, ask before you buy.
Where paraffin is used, by candle type
| Candle | Why paraffin is chosen | A named example |
|---|---|---|
| Container | Smooth tops, vivid color, strong throw in a soft grade | CandleScience used IGI 4630 for a container tutorial "due to its ability to achieve vivid colors and throw fragrance quite well," melting to 185°F, adding 1 oz fragrance per lb, pouring at 170°F with an LX 14 wick, and recommending a 3 to 5 day cure [5] |
| Pillar and votive | A hard, higher-melting grade holds its shape while the top melts | CandleScience sells IGI 1239A for pillars and votives; its category page gives no figures [6] |
| Taper | A hard grade that resists bending | See making taper candles |
| Blends | Paraffin is mixed with soy or coconut to improve smoothness, adhesion or throw | CandleScience's coconut apricot wax includes paraffin [7]; SimplySoy "mixes easily with most paraffin waxes" [8] |
Pillar paraffin is often modified with additives that the seller or the maker adds: polymers such as VYBAR for hardness, opacity and fragrance retention, and stearic acid for opacity and mold release. What each one does, and where the usage rates come from, is on the additives page.
Wicks for paraffin
CandleScience calls its LX series "our recommended wick for paraffin waxes" [9]. Supplies for Candles in the UK recommends its LX range or Stabilo wicks for paraffin and its ECO range for paraffin and soy blends [10]. Those are two suppliers' recommendations for their own wick lines. Wick series are compared on the wick types page.
The health claims made against paraffin
Paraffin is regularly described online as toxic, as releasing benzene or toluene, or as the dirty alternative to soy. Here is what each claim rests on, as far as could be traced.
| Claim | What it rests on | What the evidence supports |
|---|---|---|
| Burning paraffin releases toluene and other harmful chemicals | A 2009 South Carolina State University study. A supplier that traced it reports the study "was never published in any peer-reviewed journals" and is no longer on the university's website [11] | An unpublished result cannot be checked. It is not a basis for a claim. |
| Paraffin candles smoke and smell bad | Patent background text, for example "Conventional candles produced from a paraffin wax material typically emit a smoke and can produce a bad smell when burning," in a patent for a soy wax [12] | An applicant's description of the problem its invention addresses. It is not a measurement. |
| Scented candles harm health in normal use | A 2014 study by authors from the fragrance research institute RIFM, fragrance houses and consumer-products companies measured chamber emissions from scented candles and concluded that under normal use they "do not pose known health risks to the consumer" [13] | The most detailed exposure study found; its authors are industry-affiliated. It covers scented candles generally and does not compare paraffin with soy. |
| Soy burns cleaner than paraffin | No peer-reviewed comparison was found | No good comparative evidence either way. |
Soot, the black smoke you can see, is the part of a candle's emissions you can observe and measure in your own burn tests; ASTM F2326 is the standard method for collecting it, one of the six ASTM candle standards CPSC lists [14]. The full picture of what has and has not been studied is on the candle emissions page. Whatever wax you use, do not claim that it is non-toxic or cleaner burning without evidence; the claims rules are on what you can claim about your candle.
When paraffin is the right choice, and the next step
Choose paraffin when you are making pillars, votives or tapers that must stand on their own, when you want vivid color and a smooth top in a jar, or when you are working with a blend that includes it. Choose another wax if your label or your customers require a vegetable or beeswax candle. If you are heading toward molded candles, go next to how to make a pillar candle. If you plan to modify a paraffin with VYBAR or stearic acid, read the additives page first, because any additive is a reason to retest the wick.
