Pick up any candle in a shop and there's a good chance the label says "natural" somewhere. Or "eco-friendly." Or "clean." Or "non-toxic."
Most people assume these words mean something specific. That there's a standard behind them. A certification. An inspection.
There isn't.
"Natural" has no legal definition on a candle in the UK
There is no legal definition of "natural" when it appears on a candle label. No certification body governs the term. No testing requirement exists. No enforcement mechanism applies.
The same is true of "eco-friendly," "green," "non-toxic" and "clean-burning." Any candle brand can put any of these words on their label tomorrow. Nothing stops them.
If you're used to food labelling - where "organic" requires certification from a body like the Soil Association - this probably feels wrong. But candles operate under completely different regulations and marketing language isn't part of them.
What UK candle regulations actually cover
Candles are regulated in the UK. But the rules are about safety, not marketing claims.
CLP (Classification, Labelling and Packaging of Chemicals) is the main regulation for scented candles. If you've seen warning pictograms or allergen lists on a candle label, that's CLP. It requires candle makers to declare any allergens present in their fragrance oils - things like limonene and linalool, which are found naturally in citrus fruits, lavender and many other plants. These warnings aren't there because the candle is dangerous. They're there so that anyone with a specific sensitivity can make an informed choice. Think of it like food allergen labelling - a jar of peanut butter isn't dangerous, but the label needs to say it contains peanuts.
CLP tells you what allergens are in the candle. It doesn't tell you whether the candle is "natural."
GPSR (General Product Safety Regulations) requires all consumer products on the UK market to be safe. For candles this means fire safety testing, safety warnings based on EN 15494, traceability information and a UK Responsible Person.
GPSR ensures the candle is safe to burn. It doesn't regulate whether the word "natural" on the front of the label is accurate.
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) requires that chemical substances used in products - including fragrance ingredients - are registered and evaluated for safety. Candle makers are typically "downstream users" who must ensure their products comply with substance restrictions.
REACH controls which chemicals can be used in a candle. It doesn't control which words can appear on the marketing label.
None of these regulations define, restrict or enforce the words "natural," "eco-friendly," "green" or "non-toxic" on a candle.
What about IFRA?
IFRA - the International Fragrance Association - sets safety standards for fragrance ingredients. IFRA standards define maximum usage levels for specific fragrance compounds across product categories. Candles fall under Category 12. These limits exist to prevent adverse reactions like skin sensitisation and are based on research from RIFM (the Research Institute for Fragrance Materials).
When a candle maker says their fragrance oils are "IFRA-compliant," it means the oils have been formulated within these safe usage limits. That is a meaningful safety standard.
But there are things worth knowing about IFRA too.
IFRA membership is voluntary. It is not a legal requirement for fragrance suppliers, though most reputable ones comply. IFRA also does not regulate the word "natural." A fragrance can be IFRA-compliant whether it contains synthetic compounds, essential oils or both. And IFRA certificates are produced by fragrance suppliers themselves - there is no external body inspecting a finished candle and awarding an IFRA stamp.
IFRA compliance is a genuine safety benchmark. It is not a "natural" certification.
Other label claims worth understanding
"Natural" isn't the only term on candles that means less than you'd expect. Here are a few others worth knowing about - not because brands using them are doing something wrong, but because it helps to understand what they do and don't tell you.
"Phthalate-free" is a positive thing and phthalates are worth avoiding. But the term only covers one class of chemical compound. A fragrance can be phthalate-free and still vary widely in quality and formulation. It's a good start but it's not the whole picture. What matters most is overall IFRA compliance and the quality of the formulation as a whole.
"Triple scented" has no standard definition. It might refer to three fragrance notes (top, middle, base). It might be a comparison to older wax formulations that held less fragrance. It might just mean "strong." Most quality candles already use the maximum safe fragrance load for their wax type - you can't keep adding more without creating safety issues. It's not a regulated term so there's no way to know what a particular brand means by it.
"Vegan" means no animal products were used, which is straightforward and useful to know - especially if that matters to you. Our candles are vegan too. It's worth being aware though that "vegan" on its own doesn't cover things like carbon footprint, packaging or sourcing practices. It's one piece of information about a product, not a complete picture of its environmental impact.
"Non-toxic" has no regulated definition for candles. All combustion produces some byproducts. The 2007 Ökometric Wax and Emissions Study - funded by the European Candle Association - found that well-made candles of all major wax types produce virtually identical emissions when properly wicked and maintained. How a candle performs comes down to wick quality, fragrance load and how it's burned - not a claim on the label.
We use this word too
Our footer says "100% Natural Soy Wax." So we should explain what we mean.
When we say "natural soy wax" we're talking about the raw material. Our wax is plant-derived from soybeans. It's renewable. There's no paraffin blended in. That's a specific, verifiable claim about what the wax is made from.
Our fragrance oils are professionally formulated and IFRA-compliant - tested and approved for safety when burned.
So here's what's in a Lakeland Lights candle: soy wax, IFRA-compliant fragrance oils, cotton wick. That's it. The difference between us and a label that says "natural"? We'll tell you what that means.
What to look for when you're buying a candle
Rather than taking label claims at face value, these are more useful questions.
What is the wax made from? Soy, paraffin, coconut, beeswax and blends all have different properties. A brand that specifies the wax type is giving you something verifiable. A brand that just says "natural wax" is not.
What can the brand tell you about their fragrance oils? You don't need the exact formula - that's proprietary. But a brand should be able to tell you whether their oils are IFRA-compliant and what standard they're formulated to. If they can't or won't say, that tells you something.
Are they IFRA compliant? This is the most meaningful safety standard available for candle fragrances. It's not perfect - compliance is self-declared - but it's based on genuine safety research and most reputable fragrance suppliers adhere to it.
Will the brand actually tell you? This is the real test. Transparency isn't about revealing trade secrets. It's about being willing to answer straightforward questions about what's in the product you're burning in your home.
If a brand won't explain what "natural" means on their label, the label is doing the talking for them.
