What's Your Candle Made Of? Coconut-Apricot Wax vs Paraffin — Gloravi
Most candle shoppers never think about the wax. They read the scent name, check the price, and decide. The wax is invisible until it starts burning — and once it does, it's already in the air.
Here's what's actually happening inside a candle, and why the wax you choose matters.
What Actually Burns in a Candle
It's not the solid wax. You're not burning wax — you're burning gas.
A candle works through a continuous phase-change process. The flame's heat melts the solid wax near the wick into liquid. That liquid wax travels up the wick through capillary action. At the tip of the wick, the heat vaporizes it into gas. Those gaseous hydrocarbons combust — that's the flame you see.
Whatever is in the wax mixture becomes part of what vaporizes and burns. Whatever's in the fragrance blend. Whatever additives were included to make the wax look smoother or the scent last longer. All of it becomes airborne. You're not just smelling a candle when you burn it — you're breathing it.
Paraffin: What Most Candles Are Made Of
Paraffin wax is a byproduct of crude oil refining. It's inexpensive, holds fragrance extremely well, and burns predictably — which is why it became the industry default. The majority of mass-market candles are still paraffin.
The problem is combustion chemistry. Paraffin undergoes incomplete combustion when burned, releasing volatile organic compounds (VOCs) including benzene and toluene — both classified carcinogens. The same compounds appear in diesel exhaust. At typical home candle use levels, the concentration is far lower than industrial exposure, but they're present and they accumulate in enclosed spaces.
The black soot you see on candle jars and sometimes on walls is partially carbonized paraffin. It's also what you're breathing when a paraffin candle burns heavily.
This isn't fringe science. It's basic combustion chemistry. The candle industry often pushes back by noting that high-quality paraffin burns cleaner than cheap paraffin, which is true. Food-grade paraffin burns significantly better than industrial-grade. But if the goal is eliminating petroleum combustion byproducts entirely, paraffin is the starting point you're moving away from, not toward.
Soy Wax: Better, With Caveats
Soy wax is made from hydrogenated soybean oil. It's plant-derived, biodegradable, and burns more completely than paraffin — producing less soot and fewer VOCs. Soy candles typically burn 30% longer than paraffin candles of the same size.
The caveats are worth knowing.
First, soy wax alone is quite soft, which means many manufacturers blend it with paraffin to give it structure. Labels that say "soy wax candle" can legally contain significant paraffin percentages — there's no regulated definition of what percentage qualifies. The term "pure soy" has similar problems: it means the soy wax component is pure, not that the candle is 100% soy.
Second, the fragrance blend matters independently of the wax. A soy candle with phthalate-laden synthetic fragrance is not a clean candle, regardless of the wax.
Third, soy has a narrow temperature tolerance. It frosts (develops white surface crystals), can have adhesion issues in containers, and is generally more temperamental to work with than paraffin or coconut blends. The frosting is purely aesthetic, but the structural instability sometimes leads manufacturers to add chemical stabilizers.
Coconut Wax: What It Is and Why It Burns Better
Coconut wax is made by hydrogenating coconut oil — the same process used for soy, but starting with a different plant oil. It's soft, creamy, naturally white, and burns more cleanly than either paraffin or soy alone.
The key differences:
Scent throw. Coconut wax has an exceptional ability to hold and release fragrance. It requires fewer additives to achieve a strong, accurate scent release than soy or paraffin. This matters for candles where the scent is doing specific work — you want it to arrive in the room accurately, not muffled by incomplete diffusion.
Burn quality. Coconut wax burns more slowly and evenly than paraffin, and has less tendency toward tunneling (the problem where only the center of the candle melts, leaving wax on the sides). A well-made coconut wax candle maintains a full melt pool more reliably.
Clean combustion. Coconut wax produces minimal soot. It's an oxygenated fuel — the molecular structure includes oxygen, which supports more complete combustion than petroleum-based waxes. Cleaner combustion means less particulate matter in the air.
Renewable source. Coconuts are a high-yield perennial crop. The same tree produces fruit for 60-80 years.
The main drawback is cost. Coconut wax is more expensive than both paraffin and soy, which is why many candle brands blend it with soy rather than using it alone.
Apricot Kernel Oil: Why It's in the Blend
Gloravi's candles use a coconut-apricot soy wax blend. The apricot component is apricot kernel oil, cold-pressed from the seeds of apricots.
Apricot kernel oil is a light, slightly fruity carrier oil. In a wax blend, it contributes softness, a finer crystal structure, and a cleaner, more even surface. It also improves fragrance adhesion — the oil helps bind the fragrance to the wax more effectively, supporting a consistent scent release from first burn to last.
The result is a blend that burns consistently across the life of the candle, releases fragrance evenly without hot and cold spots in the scent, and does all of this from a base that doesn't include petroleum.
How to Compare Waxes
When comparing candles by wax type, the relevant questions are:
What's actually burning? Paraffin = petroleum combustion byproducts. Plant waxes = cleaner, more complete combustion. The distinction matters for indoor air quality.
How well does the scent reach the room? Scent throw determines whether the fragrance does its intended work. Coconut wax is among the best at this without requiring synthetic additives to boost projection.
How long does it burn? Plant waxes — coconut and soy — burn longer than paraffin per ounce, which typically means better value despite the higher ingredient cost.
What else is in it? The wick matters (cotton or wood vs. metal-core). The fragrance matters (phthalate-free vs. synthetic with undisclosed additives). The wax is the foundation, not the whole story. What makes a non-toxic candle covers the complete ingredient checklist.
Wax and the Nervous System
There's a reason this matters beyond clean ingredients.
If the goal of a candle is partly to create a specific nervous system state — to signal calm, clarity, warmth, focus — that signal is only as clean as what's delivering it. Paraffin combustion adds a layer of VOCs and soot particles to the air that compete with the scent signal. The nervous system has to process both: the intended fragrance and the background byproducts of burning petroleum.
Coconut-apricot wax is the base the Gloravi candles use because the scent should be the only thing doing work. Not the wax chemistry.

FAQ
Is soy wax actually non-toxic?
Soy wax itself burns cleaner than paraffin. But "soy candle" doesn't tell you about the wick, the fragrance, or whether the wax is actually 100% soy. A candle made from pure soy wax with a synthetic fragrance containing phthalates and a metal-core wick is not a clean candle, despite the soy base. Always look at the full ingredient picture.
What does "coconut-apricot wax" mean exactly?
It's a blend of hydrogenated coconut oil and apricot kernel oil, typically combined with a percentage of soy wax for structural stability. The coconut wax provides clean combustion and excellent scent throw. The apricot oil contributes surface smoothness and fragrance adhesion. The soy gives the blend enough hardness to hold its shape in a container at room temperature.
Can I tell the difference between paraffin and plant wax by looking at the candle?
Sometimes. Soy and coconut waxes often have a slightly softer, more matte appearance. Paraffin tends to look harder and more perfectly smooth. Natural waxes may show frosting (white surface spots) or slight surface imperfections — these are cosmetic and a sign of real plant wax, not a defect. The smell when burning is also different: paraffin candles often have a faintly petroleum-adjacent undertone, especially cheap ones.
Does the wax type affect how long the candle lasts?
Yes. Coconut and soy waxes have lower melting points than paraffin, which means they burn at a lower temperature and consume wax more slowly. A well-made coconut-soy candle typically burns 5-7 hours per ounce — so an 8-ounce candle runs 40-56 hours. Paraffin candles often run 3-5 hours per ounce.
What's the best way to burn a candle to preserve the wax quality?
The first burn matters most. Allow the candle to create a full melt pool — liquid wax reaching the edges of the container — on the first lighting. This usually takes 2-3 hours for a standard 3-inch diameter container. Extinguishing before the melt pool reaches the edges creates a "memory ring" that causes the candle to tunnel on every subsequent burn.

The flame is only as clean as what's feeding it.
