Scientists warn that romantic candlelight dinners or luxurious aromatherapy baths can be harmful to health. Many candles produce smoke that contains toxic substances associated with cancer, asthma and eczema.
Researchers say that occasional candles do not cause harm, but people should avoid using candles in bathrooms and other poorly ventilated rooms.
There is also an essential chemical in the scented candle called limonene. Limonene is considered to be a safe substance, and its citrus fragrance is refreshing, so limonene is widely used in scented candles, air purifiers and detergents.
The latest research in the UK shows that limonene is easily combined with air to form formaldehyde. Formaldehyde is a heavy industrial material used for anti-corrosion. It is a carcinogen and is extremely harmful to the human body. During the test, the researchers asked each participating household to write down the names of all the scented candles, air fresheners and cleaning products they used, as well as the frequency of usual use. The researchers then conducted tests at each home.
Aromatherapy candle paraffin ingredients are harmful to the body
Most of the scented candles on the market are made of solid paraffin. In addition, scented candles contain a lot of chemicals, which combine with air to produce substances harmful to the body.
Most of the candles sold in the UK (including scented candles) are made from solid paraffin. Paraffin wax is a by-product of the petroleum industry that releases potentially harmful chemicals such as toluene and benzene. The more expensive beeswax and soy wax were found to have no harmful substances in the test.
