Are Scented Candles Toxic or Harmful to Your Health?

Are scented candles actually toxic?

Not all scented candles are toxic, but some can emit harmful substances depending on the materials used. Cheap candles made from paraffin wax and synthetic fragrances may release pollutants like benzene, toluene, and formaldehyde, which can affect indoor air quality. This is why at Karessa Candles, we use soy wax and natural fragrances to keep your space safe and clean.

What makes some candles potentially harmful?

Toxicity in candles typically comes from:

• Paraffin wax, a petroleum by-product, which can release carcinogenic fumes when burned

• Synthetic fragrance oils, which may contain phthalates and VOCs

• Metal-core wicks, especially those containing lead (banned in many countries but still found in some imported candles)

• Artificial dyes and additives that can emit chemicals while burning

You can avoid all of these by shopping from our natural candle collection.

Do all scented candles release toxins?

No. Not all scented candles are toxic. High-quality candles made with:

• Soy, coconut, or beeswax

• Essential oil-based fragrances

• Lead-free cotton or wooden wicks

…are much cleaner and safer to burn. Check out our soy candles and gift hampers for toxin-free options.

Can scented candles affect sensitive individuals?

Yes, people with asthma, allergies, or chemical sensitivities may experience:

• Headaches

• Coughing or sneezing

• Difficulty breathing

• Irritated eyes or throat

For these individuals, we recommend our unscented candle jars for ambiance without scent exposure.

How can you enjoy candles safely?

Here are a few tips:

• Burn candles in well-ventilated rooms

• Trim the wick to ¼ inch before each use

• Limit burning time to 3–4 hours

• Avoid placing candles near drafts to reduce soot

• Choose natural wax candles, like the ones in our collection
