Hello, I'm an expert in the field of environmental health and safety. I can provide you with information on the potential toxicity of candles.

Candles can be toxic if they release harmful chemicals when burned. The toxicity of a candle depends on several factors, including the type of wax, the wick, and any additives or fragrances used. Here's a breakdown of these components:


1. Wax: Most candles are made from paraffin wax, which is a byproduct of petroleum. When burned, paraffin wax can release small amounts of toluene and benzene, both of which are known carcinogens. However, beeswax and soy wax are natural alternatives that burn cleaner and produce fewer harmful emissions.


2. Wick: The wick can also contribute to toxicity. Metal wicks, for example, can release lead when burned. It's safer to use cotton or wooden wicks.


3. Additives and Fragrances: Many candles are scented with synthetic fragrances that can release volatile organic compounds (VOCs), which can cause respiratory issues and other health problems. Unscented candles are a safer option.


4. Lead Wicks: Some candles have wicks that contain lead to improve burn quality. Lead is a toxic metal, and exposure can be harmful, especially to children.


5. Soot: All candles produce some amount of soot when burned, which can be inhaled and is considered harmful to health.

To minimize exposure to potentially harmful substances, it's best to choose candles made from natural waxes, with natural wicks and without added fragrances or dyes.

Most candles are made of paraffin wax, which creates highly toxic benzene and toluene when burned (both are known carcinogens). In fact, the toxins released from paraffin candles are the same as those found in diesel fuel fumes.read more >>
