Probably. Studies have shown that beeswax, paraffin and vegetable-based waxes are biodegradable. The vast majority of candles today are made primarily from these waxes.

No. By definition, a wax is not soluble in water.

Metal-core wicks are sometimes used in container candles and votives to keep the wick upright when the surrounding wax liquefies during burning. Today's metal-core wicks are made with either zinc or tin. Scientific studies have repeatedly shown both zinc- and tin-core wicks to be safe and non-toxic.

No. Paraffin wax – like all candle waxes - is non-toxic. In fact, paraffin is approved by the U.S. Food and Drug Administration for use in food, cosmetics, and medical applications. Food-grade paraffin is commonly used for manufacturing candles.  

Candles are safe when burned properly, responsibly and according to manufacturer directions. Nevertheless, it’s important to remember that a burning candle is an open flame, and thus a potential fire hazard if not monitored carefully.

When burning candles, consumers should follow these basic safety rules:

Keep lighted candles within your sight. Never leave a burning candle unattended.

Never burn a candle on or near anything that can catch fire.

Keep candles out of the reach of children and pets.

Trim wicks to ¼ inch prior to each use.

Keep candles away from drafts and vents.

Always use an appropriate candleholder placed on a stable, heat-resistant surface.

Read and follow all manufacturer instructions carefully.
