What’s Really in Your Candles?

Most candles on the market contain paraffin wax, a petroleum byproduct that releases known carcinogens like toluene and benzene when burned. According to Women’s Health Network, these candles can also be scented with synthetic fragrances that release phthalates and other compounds linked to hormone disruption and airway irritation.

The good news? If you light candles regularly, switching to non-toxic options may help improve your indoor air quality. Look for candles made from 100% beeswax, coconut wax, or soy wax, and choose ones scented with essential oils rather than synthetic fragrances. Essential oils offer a cleaner alternative without these harmful chemicals.

Beyond better air quality, non-toxic candles also burn 30-50% slower than paraffin and are less likely to leave black soot on your walls or jars.

Not All ‘Natural’ Candles Are Created Equal

While soy, beeswax, and coconut wax candles are cleaner alternatives to paraffin, quality varies widely. Many brands blend natural wax with paraffin or use synthetic fragrances, which release the same harmful chemicals you’re trying to avoid. Always check the full ingredient list before buying.

What to Look for in Non-Toxic Candles

When shopping, check labels carefully. Avoid candles that list “fragrance” or “parfum” as these are umbrella terms that hide synthetic chemicals. Non-toxic candles have three essential parts: clean wax—like 100% pure beeswax, organic soy, coconut, or a soy-coconut blend—essential oil-based scents, and lead-free wicks (cotton or wood).

Look for brands that list all their ingredients—complete transparency makes shopping easier. If you want to skip the search, you can try making your own at home; it’s simpler than you’d think and feels like a calm ritual. Alternatively, all of Pao Apothecary’s candles are hand-poured in small batches, with organic soy wax, pure essential oils, and cotton wicks.

In Conclusion

You shouldn’t have to choose between a cozy atmosphere and cleaner air quality. If you light candles regularly, switching to non-toxic candles is one of those small changes that adds up over time, with fewer chemicals and candles you can actually feel good about.
