If you see the word “natural” on a candle, you probably assume it is safer to burn, completely chemical free, and better for the planet. But in the candle industry, “natural” is essentially a marketing term with no strict rules. Here is the honest truth about what goes into plant based waxes, why origin does not guarantee safety, and what you should actually look for.
Walk into any artisan market or browse online, and you will see the word “natural” plastered across hundreds of candle labels.
It is a beautiful, reassuring word. When we see it, we naturally assume the candle is safer for our health, burns cleaner in our homes, and is entirely sustainable. But the truth is, the word tells you almost nothing on its own.
This isn’t because candle makers are intentionally trying to trick you. It happens because candles sit right at the intersection of chemistry, fire, and marketing, and those three things rarely fit neatly onto a minimal, aesthetic label.
To really understand what you are burning in your home, we have to look past the buzzwords. We need to look at where an ingredient comes from, how it is processed, and most importantly, how it behaves when you actually light the wick.
The problem with the word “natural”
Here is the most important thing to know: “natural” is not a regulated safety label.
There is no strict rulebook saying what a candle must contain to use that word. Two completely different candles can both call themselves natural while being made in entirely different ways.
When a brand uses the word, they usually just mean one of the following:
- The wax comes from plants instead of fossil fuels.
- The scent uses essential oils.
- The candle is vegan friendly.
- They haven’t used synthetic dyes.
None of those things are bad. In fact, they are often great choices. But none of them guarantee how safely or cleanly that candle will burn in your living room.
A more honest way to look at candle wax
Instead of relying on marketing terms, it is much more helpful to look at how much a material has been processed.
Naturally occurring materials
These are things that exist in nature in pretty much the exact form we use them. Beeswax is the classic example here. While it goes through some filtering to remove debris, it is as close to “raw” as a candle gets. But remember: just because something comes straight from nature does not automatically mean it burns perfectly or is the most sustainable choice for mass production.
Naturally derived materials (Plant based waxes)
This is where almost all modern plant based candles sit, including soy, rapeseed, and coconut wax.
These start out in nature as plants. But you can’t make a candle out of liquid oil. To turn that liquid oil into a solid wax that holds its shape at room temperature, it has to go through a chemical process called hydrogenation.
This process is absolutely necessary to create a stable, safe candle. But it is important to be honest about it. Once a plant oil has been hydrogenated, it is no longer “raw nature.” It has been intentionally modified by humans.
Calling a heavily processed, hydrogenated plant wax “100% natural” can be incredibly misleading if you, as the buyer, think that means it was scooped straight out of a coconut or a soybean pod without any scientific intervention. We prefer the terms plant based or naturally derived. It is just more honest.
Synthetic and nature identical materials
These are materials made in a lab. In the candle world, this usually means fragrance oils or performance additives.
The word “synthetic” gets a terrible reputation in wellness circles, but the reality is much more nuanced. Sometimes, recreating a molecule in a lab is actually much safer and more consistent than trying to extract it from nature. It also prevents the over harvesting of rare plants and takes the pressure off global land use.
Safety is always about the specific substance, the dose, and how it reacts to heat, not just whether it was born in a field or a laboratory.
Why we chose rapeseed and coconut wax at Purscents
When we were developing our candles at Purscents, we tested numerous waxes. We ultimately chose a blend of rapeseed and coconut wax, deliberately moving away from soy.
We didn’t do this because soy is inherently “toxic” or bad. We did it because sustainability is about the bigger picture. Rapeseed is widely grown across Europe, which massively reduces the carbon footprint tied to shipping it over to us here. When blended with responsibly sourced coconut wax, we found it gave us a beautifully stable burn and threw scent incredibly well, meaning we didn’t have to overload the candle with fragrance.
We made our choice based on supply chains, real world burn testing, and land use, not just because a certain wax sounded good on a label.
The biggest misconception of all
In today’s wellness culture, “natural” has become a shortcut for “safe and non toxic.” And that is where the danger lies. It makes us stop asking questions.
But natural is just an origin story. It tells you where a material started its life. What actually matters for your health and your home is what happens to that material when you set it on fire.
A poorly made “100% natural” candle with the wrong wick can pump out thick black soot, while a carefully engineered synthetic blend candle can burn incredibly cleanly.
Your quick checklist for buying candles
Next time you are shopping for a candle and see big claims, ask yourself:
- Does the brand actually tell you what wax they use, or do they just say “natural wax”?
- Do they talk about their wick choices and burn testing, rather than just listing ingredients?
- Do they provide clear advice on how to trim your wicks to reduce soot and smoke?
- Do they explain their sustainability choices in detail, or just rely on buzzwords?
Why I am sharing this
The conversation around “non toxic” and “natural” home fragrance has become exhausting. On one hand, you have brands claiming their candles are perfectly pure. On the other, you have social media influencers telling you to throw all your candles in the bin. Neither extreme reflects reality.
As candle makers who develop products for ourselves and other brands, we spend our days watching how wax, wicks, and airflow interact in real spaces. At Purscents, we believe lighting a candle should bring you comfort, not anxiety.
Wax is just one piece of the puzzle. The fragrance you choose matters just as much. In our next post, we will be tackling the next big question: Are essential oil candles actually cleaner to burn?
