Non-Toxic Candles Ireland: What to Look For and Why It Matters
This guide was written by Paula McGovern, founder of Wizard & Grace Wellbeing. Paula started making essential oil candles in West Cork after developing a sensitivity to synthetic fragrance and finding that genuinely natural candles were almost impossible to find in the Irish market. Every Wizard & Grace essential oil blend is formulated by Paula. This is not a theoretical guide - it comes from years of reading labels, testing products, and learning exactly what makes a candle genuinely clean.
Ever lit your favourite scented candle, only to notice a headache creeping in an hour later? Or spotted black soot collecting on walls near your candle collection? If you're nodding along, you're not alone - and it might be time to reconsider what's actually burning in your living room.
The problem isn't candles. It's what's in them.
Most conventional candles are made with paraffin wax, synthetic fragrances, and metal-core wicks - all of which can release harmful chemicals into the air when burned. Over time this affects indoor air quality, irritates allergies, and impacts overall wellbeing. Not exactly the relaxing atmosphere you were hoping for.
The good news is that genuinely clean candles do exist. But with so much greenwashing in the market - brands using words like "natural," "clean," and "eco" with nothing to back them up - knowing how to find them requires knowing what to look for.
This guide explains exactly that.
Why Non-Toxic Candles Matter
The concerns around conventional candles fall into three main categories.
Paraffin wax is a petroleum byproduct - what's left over after crude oil is refined into fuel. When burned it releases compounds including benzene and toluene, both recognised by the EPA as hazardous air pollutants. Burning multiple paraffin candles regularly in an enclosed space creates measurable indoor air pollution.
Synthetic fragrance is listed on labels simply as "fragrance" or "parfum" - a legal catch-all that can contain hundreds of individual chemical compounds, none of which need to be disclosed individually. Among the most concerning are phthalates — chemicals used to make fragrance last longer that are classified as endocrine disruptors and have been linked to hormonal disruption, reproductive concerns, and developmental issues.
Metal-core wicks - less common now but still found in some imported candles — can contain zinc or lead, releasing heavy metals into the air when burned.
Beyond immediate reactions like headaches and respiratory irritation, long-term concerns include allergic reactions, asthma flare-ups, hormone disruption, and indoor air pollution levels that can exceed outdoor pollution in urban areas.
Switching to genuinely non-toxic candles removes these specific risks. Natural waxes burn cleaner, essential oils provide real aromatherapy benefits without synthetic compounds, and clean wicks mean nothing unwanted going into your air.
What Actually Makes a Candle Non-Toxic
The word "non-toxic" has no regulatory definition for candles. Any brand can use it. The only way to know if a candle is genuinely clean is to look at the specific ingredients — not the marketing language on the front of the jar.
Here is what to check.
The Wax
Natural waxes burn cleaner than paraffin and come from renewable rather than petroleum sources. The main options are:
Rapeseed wax — sustainably grown in Europe, increasingly popular among Irish candle makers for its clean burn and low carbon footprint. A genuinely local and sustainable choice.
Coconut wax — excellent scent throw, clean-burning, and derived from a renewable source.
Beeswax — one of the cleanest burning waxes available. Said to release negative ions that help purify air. Ideal for those with sensitivities.
Soy wax - better than paraffin but comes with social justice and intensive farming issues around GMO farming and pesticide use. This is why we do not use in our Wizard & Grace Candles.
What to avoid: Paraffin wax, and any label that says "wax blend" without specifying what's in the blend — this often means paraffin mixed with a small amount of natural wax to allow a "natural" claim.
The Fragrance
This is where most so-called natural candles fall short — and where your headaches are most likely coming from.
Pure essential oils are derived directly from plants through steam distillation or cold pressing. They contain no phthalates, no synthetic compounds, and no undisclosed ingredients. They also deliver genuine aromatherapy benefits - the therapeutic compounds in the plant are present in the oil and interact with your nervous system when inhaled.
Synthetic fragrance is a laboratory-created compound designed to mimic a scent. It may contain phthalates, synthetic musks, and dozens of other compounds that don't need to be disclosed. A candle can legally be called an "aromatherapy candle" while containing zero essential oils and 100% synthetic fragrance.
What to look for on the label: named essential oils listed individually — lavender, clary sage, frankincense, and so on. If the label says "fragrance," "parfum," or "fragrance oil" without further specification, you don't know what's in it.
The Wick
Often overlooked but important.
Cotton wicks are the standard for clean-burning candles — widely used by quality candle makers and produce minimal soot.
Wooden wicks create a satisfying crackling sound and burn cleanly.
What to avoid: metal-core wicks, which may contain zinc or lead. If you're unsure, rub the unlit wick against white paper — a grey pencil-like mark indicates a metal core.
The Packaging
A genuinely sustainable candle brand thinks beyond the candle itself. Look for recyclable glass or tin containers, plastic-free packaging, compostable or biodegradable labels, and local production to minimise carbon footprint.
The Non-Toxic Candle Checklist
Before buying any candle, ask these five questions:
1. What is the wax? It should name a specific natural wax — rapeseed, coconut, beeswax, or organic soy. "Premium wax blend" without further detail is a red flag.
2. What is the fragrance? It should list named essential oils. "Fragrance" or "parfum" on its own means you don't know what's in it.
3. What is the wick? Cotton or wood. Not metal-cored.
4. Are ingredients fully disclosed? Brands that care about ingredients will tell you exactly what's in their products. If they won't or can't, that tells you something.
5. Are claims specific or vague? "Natural," "clean," and "eco-friendly" mean nothing without specifics to back them up. Look for concrete ingredient facts, not marketing language.
How to Match Clean Candles to Every Room
Where you place a candle matters as much as what's in it. With a little intention, you can use non-toxic candles to genuinely support different states throughout your day.
Bedroom: Lavender, chamomile, and clary sage for sleep and relaxation. These three oils work synergistically — lavender addresses anxiety, clary sage lowers cortisol, chamomile gently sedates without grogginess. Our Rest candle blends all three specifically for sleep.
Home office: Peppermint, eucalyptus, and rosemary for focus and mental clarity. These stimulate the nervous system and improve alertness without overstimulation. Our Flow candle — peppermint, eucalyptus and may chang — works well here.
Living room: Uplifting oils like bergamot, orange, and rosemary lift mood and energy. Our Courage candle with rosemary, bergamot and orange is ideal for a main living space.
Bathroom: Grounding and calming scents like cedarwood, elemi, or patchouli for a spa-like atmosphere. Our Peace candle uses these to create stillness and calm.
Gifting: A candle built around a specific intention — sleep, courage, peace, renewal — makes a far more thoughtful gift than a generic scented candle. Our gift sets pair candles with matching pulse point oils for a complete wellbeing experience.
The Wizard & Grace Standard
Wizard & Grace was founded in 2022 by Paula McGovern after she developed an allergy to synthetic fragrances. Unable to find candles she could safely burn at home, she made her own.
Every Wizard & Grace candle is made to a standard Paula would burn herself:
- 100% natural rapeseed and coconut wax blend — no paraffin
- Pure therapeutic-grade essential oils only — no synthetic fragrance, no phthalates
- Cotton wicks
- FSC-certified compostable packaging
- Every essential oil named on every product label
- Hand poured in Ireland in small batches
Each candle is built around a specific wellbeing intention — Rest, Peace, Courage, Renew, Flow, Gratitude, Enchant, Believe. The essential oil blend in each one is formulated to actively support that state, not just to smell like it.
This is the standard we'd encourage you to hold any candle brand to — whether you buy from us or not.
Frequently Asked Questions
Are scented candles toxic?
Conventional scented candles made with paraffin wax and synthetic fragrance can release harmful compounds when burned — including benzene, toluene, and phthalates. Whether this constitutes "toxic" depends on concentration and exposure levels. The precautionary approach is to choose candles made with natural wax and pure essential oils, burn them in ventilated spaces, and avoid prolonged burning in small enclosed rooms.
What candle wax is safest?
Rapeseed wax and coconut wax are among the cleanest burning natural waxes available. Beeswax is also excellent. Soy wax is better than paraffin but comes with questions around GMO farming and pesticide use. Paraffin — derived from petroleum — is the wax to avoid. If a label says "wax blend" without specifying the components, treat it with scepticism.
Are soy candles really non-toxic?
Soy candles are significantly cleaner than paraffin candles but "soy" alone doesn't make a candle non-toxic. Many soy candles still use synthetic fragrance — which can contain phthalates and other endocrine-disrupting compounds. Check both the wax and the fragrance source before assuming a soy candle is clean.
Are essential oil candles healthier than scented candles?
They can be - when they genuinely contain therapeutic-grade essential oils rather than synthetic fragrance. The distinction matters because essential oils contain the actual plant compounds that interact with your nervous system, while synthetic fragrance mimics the smell without delivering therapeutic effect. Always check the label for named essential oils rather than the word "fragrance."
What candles are safe for people with allergies or asthma?
Candles made with natural wax and pure essential oils are generally better tolerated by people with fragrance sensitivities, allergies, or asthma. Wizard & Grace was founded specifically because Paula developed an allergy to synthetic fragrance. That said, even natural essential oils can trigger sensitivities in some people — if you're highly sensitive, test any new candle in a well ventilated space first.
What ingredients should I avoid in candles?
Paraffin wax, synthetic fragrance or parfum, phthalates, artificial dyes, and metal-core wicks. The word "fragrance" on a label is a legal catch-all that can contain hundreds of undisclosed chemical compounds including phthalates — classified endocrine disruptors. If you can't see a full, named ingredient list, be sceptical.
Are paraffin candles bad for indoor air quality?
Paraffin wax is a petroleum byproduct that releases compounds including benzene and toluene when burned — both recognised by the EPA as hazardous air pollutants at sufficient exposure levels. Regular use of multiple paraffin candles in poorly ventilated spaces can meaningfully affect indoor air quality. Switching to natural wax candles and ventilating when burning anything significantly reduces this risk.
What does "non-toxic candle" actually mean?
Nothing legally — the term has no regulatory definition for candles. Any brand can use it. The only way to verify a genuinely non-toxic candle is to check the specific ingredients — named essential oils, natural wax, cotton or wood wick, full transparency on everything inside.
In Summary
A genuinely non-toxic candle has natural wax, named essential oils, a cotton or wood wick, and full ingredient transparency. The word "non-toxic" on a label means nothing without those specifics to back it up.
Apply the checklist above to any candle before you buy. Read the label, look for named ingredients, and be sceptical of vague claims.
