Candles are supposed to make your home feel better — not worse. But if you have ever gotten a headache from burning a candle, or wondered what is going into your air when you light one, those concerns are worth taking seriously.
The short answer: some candles are a problem. Many are not. Here is how to tell the difference — and why wax type matters more than most brands want to admit.
What Makes a Candle Potentially Toxic?
Most candle safety concerns come down to three ingredients:
1. Paraffin Wax
Paraffin is a petroleum byproduct found in most cheap, mass-produced candles. When burned, it can release volatile organic compounds (VOCs) including benzene and toluene — both known carcinogens. If a label says paraffin or does not specify wax type at all, that is a red flag.
2. Phthalates in Fragrance
Fragrance ingredients do not have to be individually disclosed in the US — brands can list everything under "fragrance." Many synthetic fragrance blends contain phthalates, linked to hormone disruption. Unless a candle explicitly says phthalate-free, you cannot assume it is.
3. Vague Wax Blends
Soy blend, coconut blend, natural blend — these labels can legally include a high percentage of paraffin. A candle marketed as "coconut wax" may actually be coconut-soy, coconut-apricot, or coconut-paraffin. Without full transparency, you are guessing.
What Does "Non-Toxic" Actually Mean for Candles?
"Non-toxic" is not a regulated term — any brand can use it. What actually matters:
• Phthalate-free fragrance oils — explicitly stated, not implied
• California Prop 65 compliant — the strictest consumer safety standard in the US. If a brand is compliant, their ingredients have been verified against the list of chemicals known to cause cancer or reproductive harm.
• 100% natural wax — not a blend. Pure wax with a clear origin.
• Cotton or wood wicks — no metal cores
A brand that is genuinely non-toxic will state all of these things clearly. If any are missing, that is worth noticing.
Wax Comparison: Paraffin/Soy Blend vs. Coconut Wax
Paraffin Soy Blend
- Releases VOCs Yes — benzene,
- Phthalate-free Rarely/Sometimes
- Prop 65 compliant - Rarely
- Burns clean - No
- Petroleum-based - Yes
- Scent throw Moderate
How Sorelle Candles Are Different
Every Sorelle candle is made with 100% coconut wax — not a blend. Not coconut-soy, not coconut-apricot.
Pure coconut wax that burns at a lower temperature, produces less soot, and holds significantly more fragrance oil than paraffin or soy. That is why our candles fill 700–1,500 square feet instead of just drifting weakly from the jar.
Our fragrances are phthalate-free and our candles are California Prop 65 compliant — the most rigorous safety standard in the US. Hand-poured in Houston, Texas, and transparent about every ingredient we use.
How to Burn Any Candle More Safely
Frequently Asked Questions
Are all candles toxic?
No. Candles made with 100% coconut, soy, or beeswax — phthalate-free fragrances and cotton wicks — are safe when burned properly. The issue is paraffin wax, phthalate-containing fragrance, and brands that are not transparent about ingredients.
Can burning candles make you sick?
Paraffin candles burned regularly in poorly ventilated spaces can contribute to headaches, respiratory irritation, and aggravated asthma. Clean-burning candles made with natural wax and phthalate-free fragrance do not carry these risks.
Is coconut wax the safest candle wax?
Coconut wax is among the cleanest options available. It burns at a low temperature with minimal soot and holds more fragrance than paraffin or soy. The key distinction is 100% coconut wax vs a coconut blend, which may contain soy or paraffin.
What does California Prop 65 compliant mean for candles?
California's Prop 65 requires disclosure of chemicals known to cause cancer, birth defects, or reproductive harm. A Prop 65 compliant candle has been verified to not contain those chemicals above safe threshold levels. Most candle brands do not meet this standard.
How can I tell if my candle is toxic?
Check for: paraffin wax or unlabeled wax type, no phthalate-free claim, metallic-looking wicks, excessive soot or smoke. Brands that are genuinely clean will state their wax type, phthalate-free fragrance, and Prop 65 compliance clearly.
