Question: are vegetable oil candles safe?
Answer: There are no rules or bans in the works for paraffin candles and those scented with synthetic oils. ... Buy candles made from 100 percent vegetable-based waxes, which are also nontoxic. To reduce soot, no matter what kind of wicks are in your candles, trim wicks to 1/8 inch, and do not burn candles in a drafty area.
