We make wax melts. Pure coconut wax, hand-poured in Shropshire. So we're not a neutral party — we'll be upfront about that from the start.
But we've also been in this industry long enough to see a lot of nonsense written about wax. Paraffin described as basically a biohazard. Soy marketed as the ethical choice while quietly linked to industrial farming. Coconut wax sold as a miracle material by brands who are actually using a coconut-soy blend.
This post is for people who want the actual picture. If you're trying to make a genuinely informed choice — whether you're a customer, a maker, or just someone who uses a lot of wax melts and wants to know what's in them — we'll try to be useful rather than self-serving.
We'll cover how each wax is actually made, the real environmental picture, what the health claims are actually based on, and how they compare for wax melts specifically. We'll also tell you why we chose coconut wax — and acknowledge the parts of that choice that aren't straightforward.
How Each Wax Is Actually Made
The word "natural" gets used a lot in this industry. It's worth slowing down on it, because none of these waxes comes out of the ground or off a tree ready to use. They're all processed materials.
Paraffin wax is a byproduct of petroleum refining. Crude oil is distilled, and the waxy fraction left over is further refined, de-oiled, and bleached. It's a petrochemical product. There's no other way to describe it.
Soy wax starts as soybean oil, which is extracted from soybeans and then hydrogenated — a process that adds hydrogen to the oil under heat and pressure to make it solid at room temperature. It's also typically bleached and deodorised. The raw ingredient is plant-based, but the finished product is the result of industrial processing.
Coconut wax begins as cold-pressed coconut oil. That oil is then hydrogenated in the same way as soy — it needs to be, because coconut oil is liquid at room temperature and would be useless as a wax without it. So while the source is plant-based, the process is not meaningfully different from how soy wax is made.
"Natural" is a spectrum, not a binary. Coconut and soy waxes come from plants; paraffin comes from fossil fuel. That's a real difference and it matters. But anyone marketing their coconut or soy wax as "completely natural" or "unprocessed" is being loose with the truth.
Paraffin: The Honest Picture
Paraffin wax has a bad reputation in the indie fragrance world, and some of it is deserved — but some of it is based on a single study that doesn't hold up well.
The widely repeated claim that paraffin candles release benzene, toluene, and other toxic compounds at levels dangerous to human health comes largely from a 2009 study by researchers at South Carolina State University. That study was never published in a peer-reviewed journal, its methodology has been questioned, and it's never been replicated. The US National Candle Association and various independent researchers have since concluded that in a normally ventilated home, the combustion byproducts from a well-made paraffin candle or melt are not at levels associated with health risks. Overclaiming on this has been a genuine problem in the alternative wax industry, including by brands who should know better.
So why do we not use paraffin? A few honest reasons:
- It is a petroleum derivative, and we'd rather not use fossil fuel products where there's a practical alternative.
- It does produce more soot than plant-based waxes — which affects air quality in your home over time, even if it doesn't hit toxic levels.
- It tends to produce a harder, faster scent throw that fades quickly, rather than a sustained release.
Paraffin is cheap, widely available, performs reliably, and holds fragrance well. That's why it still dominates the mass-market candle and melt industry. The reasons to avoid it for daily home use are real — just don't let anyone tell you it's the equivalent of burning a tyre in your living room.
Soy Wax: What the Marketing Often Misses
Soy wax has been positioned as the responsible alternative to paraffin for about twenty years now. Some of that positioning is fair. Some of it isn't.
The genuine upsides: soy wax burns cleaner than paraffin with less soot, it comes from a renewable crop, it's widely available, and it's relatively affordable for makers and customers alike. It also performs well in candles — it has good adhesion to glass, a reasonable fragrance load, and a clean appearance.
The deforestation narrative is where things get complicated. You'll often see soy wax criticised with reference to Amazon deforestation. That link is real — but it's geographically specific. Amazon deforestation is primarily driven by Brazilian soy production, most of which goes to animal feed and beef farming, not fragrance products. Most UK and European soy wax comes from US-grown soy — Iowa, Illinois, Indiana — cultivated on existing agricultural land that has been farmed for generations. It is not coming from freshly cleared rainforest. The "soy wax = destroying the Amazon" claim, as applied to most UK products, is misleading.
That doesn't make soy wax environmentally uncomplicated. US soy farming is heavily industrialised: monoculture, high pesticide use, and largely GMO crops. The environmental impact is real; it's just different from what the marketing usually implies.
The processing reality, as above: soy wax is hydrogenated, bleached, and deodorised. It's not a raw plant product.
Coconut Wax: Genuine Strengths and Honest Caveats
This is the wax we use, so read this section with that in mind. We'll try to be fair.
The strengths are real. Pure coconut wax has a fragrance load capacity of up to 10–12%, comparable to paraffin and higher than most soy waxes. Its melt point is low — around 35–40°C — which means it releases fragrance slowly and evenly rather than all at once. In a wax warmer, that translates to a scent that builds gradually and holds for longer, rather than hitting hard and fading. In our experience, most people who switch to coconut wax notice the scent feels more present throughout a longer burn, rather than peaking in the first twenty minutes.
The blending problem. This is important: a lot of what's sold as "coconut wax" isn't pure coconut wax. Pure coconut wax is very soft — which is fine for wax melts, where structural integrity doesn't matter, but genuinely difficult for candles, where it can pool, crater, or sweat. Many products labelled as "coconut wax candles" are actually coconut-soy or coconut-paraffin blends. This isn't inherently dishonest, but it does mean the label tells you less than you might think. If you care, ask the brand specifically what's in their wax.
The environmental picture. Coconut farming is generally not associated with deforestation. Coconut palms grow for 60–80 years, sequester carbon, and in their natural growing regions require no irrigation. The farms tend to be smaller and less industrialised than US soy operations. That's all genuinely positive. But the supply chain is long — coconuts come from the Philippines, Indonesia, Sri Lanka, or India — and the shipping distance to the UK, plus the processing involved, means the environmental case isn't as simple as "it grows on a tree so it's fine."
Side-by-Side Comparison
A quick reference for the key differences:
| Wax type | Source | Processing | Fragrance load | Scent throw character | Clean burn | Environmental notes | Typical cost per melt |
|---|---|---|---|---|---|---|---|
| Paraffin | Petroleum (refined) | Heavy — distillation, de-oiling, bleaching | 6–12% | Strong initial hit, fades faster | More soot than plant waxes | Fossil fuel derivative; not renewable | Lowest |
| Soy wax | Soybeans (hydrogenated oil) | Heavy — hydrogenation, bleaching, deodorisation | 6–10% | Moderate, reasonably even | Cleaner than paraffin | Renewable; monoculture, GMO, pesticide-heavy; deforestation link overstated for UK products | Low–mid |
| Coconut wax | Coconut oil (hydrogenated) | Cold-pressing then hydrogenation | Up to 10–12% | Slower build, more sustained, longer-lasting | Clean — low soot | Renewable; not linked to deforestation; long supply chain; often blended in practice | Higher |
For Wax Melts Specifically
Most of the conversation about wax types centres on candles, but wax melts behave differently — and that changes which wax performs best.
In a candle, you need the wax to hold its shape, adhere to the container, and burn with a stable flame. That's why coconut wax is genuinely challenging in candles and why brands often blend it. For wax melts, none of that applies. The wax just needs to melt evenly in a warmer, release fragrance well, and not overheat or pool awkwardly.
Paraffin in a wax warmer will often produce a strong initial scent that diminishes noticeably within an hour or two. Soy performs better than paraffin for sustained release, but in our experience it can still front-load the scent throw. Coconut wax's low melt point is an actual advantage here: it melts gradually, releases fragrance at a lower temperature, and holds scent more evenly across the full duration. Our discs are rated at 16–20 hours each, and most customers tell us the scent stays noticeably present throughout rather than fading after the first session.
If you use wax melts frequently and care about sustained scent rather than an immediate hit, the wax type matters more than most product descriptions let on.
Why We Chose Coconut Wax
We use pure coconut wax — not a blend — and we hand-pour in Shropshire. Here's the honest version of why.
Performance was the first reason. For wax melts specifically, coconut wax's melt point and fragrance capacity work together in a way that produces a better result for sustained scent release. We tested other waxes. Coconut wax won on what we were actually trying to achieve.
The environmental case was the second. It's not perfect — nothing with a supply chain that starts in Southeast Asia is — but we'd rather use a renewable, carbon-sequestering crop than a petroleum product, and we'd rather know the farming isn't associated with habitat destruction.
It's not the cheapest choice. Coconut wax costs significantly more than paraffin and more than soy. That feeds into our pricing, and we don't apologise for it — it's the material we'd want to use ourselves.
If you want to try our coconut wax melts, our pick and mix botanical wax melts are a good place to start — you can build your own selection across different scents without committing to a full pack.
