Bath and Body Works candles are primarily made from paraffin wax, which is a petroleum-based product. When burned, they release particulate matter and volatile organic compounds (VOCs), including toxic BTEX chemicals. The fragrances used in Bath and Body Works candles are made with a number of synthetic chemicals that can be harmful to health, including phthalates, which are hormone disruptors. Other additives like dyes and stabilizers are also used, some of which are linked to health concerns. However, according to the safety data sheets provided by Bath and Body Works, no specific material or group of materials is likely to react with the product to produce a hazardous situation.

In summary, the positive aspects of Bath and Body Works candles are their pleasant fragrances and the fact that they are widely available. However, the negative aspects include the use of paraffin wax, synthetic fragrances, and other additives that can be harmful to health and the environment.
