Candles and Home Fragrance Swaps
Most conventional candles burn paraffin wax and synthetic fragrance. Both release compounds into the air you breathe for hours after use. The alternatives burn cleaner, smell better and last longer.
Why conventional candles are a concern
Most candles sold in the UK are made from paraffin wax, a petroleum byproduct. When burned, paraffin releases benzene and toluene, both of which are known carcinogens and VOCs. Studies have found that burning paraffin candles indoors creates air quality comparable to light traffic pollution.
The synthetic fragrance oils used to scent most candles add a further layer of concern. Fragrance is an unregulated category and the compounds released when synthetic fragrance burns at high temperatures include phthalates, formaldehyde and acetaldehyde. These linger in the air long after the candle is extinguished.
Beeswax and soy candles burn significantly cleaner. Beeswax actually produces negative ions when burned, which bind to airborne particles and help clean the air. Scented with pure essential oils rather than synthetic fragrance they are the only genuinely clean candle option.
