Soy candles are candles made from soywax, which is a processed form of soybean oil. They are usually container candles, because soy wax typically has a lower melting point than traditional waxes, but can also be made into pillar candles if certain additives are mixed into the soy wax. And it is softer than paraffin wax but safer I guess. (https://en.wikipedia.org/wiki/Soy_candles)
Beeswax (cera alba) is a natural wax produced by honey bees of the genus Apis. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols. (https://en.wikipedia.org/wiki/Beeswax)
Health Benefits:
Soy Wax - Soy wax is vegetable wax from the oil of soybeans. It's a renewable source and is a neutral carbon product so It hasn't had any negative impact in the environment. Soy wax is clean burning and does not release any toxins, carcinogens or any pollutants (compare to paraffin wax) which mean it less likely to trigger allergy. Soy wax won't release petrol-carbon soot like what you get from paraffin wax products meaning no more black marks from the wall...
Bees Wax - Beeswax candles produce negative ions when burned, and those ions help to neutralize pollutants in the air. This helps eliminate dust, odors, and mold in the atmosphere, easing allergy and asthma symptoms and improving breathing for anyone nearby. It is meant to help Asthma and Allergy relief. It does not harm the environment. Chemical free production as Beeswax is used in its native raw state which does not involve bleaching or hydrogenation. Beeswax is perfect mixed with essential oil with no chemical or synthetic additives to it. Beeswax candles are sootless and dripless and burn for hours without producing any soot and drip.
And I love the smell of Beeswax melting....
