There are many different types of waxes available for candle-making. The type of wax effects the way the candle burns and the amount of fragrance it provides.
Soy wax burns at a low temperature so it liquefies quickly which makes it easy to burn evenly. Since soy wax is cool to the touch when it is liquid, the liquid wax of some soy wax candles can be rubbed into the skin as a moisturizer to help heal dry skin. Soy wax is a friendly candle wax since it is a renewable resource. When a soy wax candle re-solidifies after burning, it has a "bumply" surface. There is nothing wrong with that and it doesn't affect subsequent burns, it's just somewhat unsightly. Soy wax does not typically provide as much fragrance as paraffin wax, so in a natural soy wax candle, the fragrance can be subtle. Some candlemakers use fillers or artificial fragrances to compensate for the inadequate scent throw of soy wax. Some soy wax candle makers state that soy wax burns slower that paraffin, but we haven't found that to be true. We actually find it to burn quicker. (Our longest lasting candle line is Voluspa and they don't use any soywax.) It's misleading when candles say "Soy Wax" on the packaging. To be called a "Soy Wax" candle, it needs to have at least 50% soy wax, but it may be blended with other waxes, including paraffin, so beware. Aromatherapy Interventions, Archipelago Botanicals and Paddywax are Soy Wax candles. A Scent of Scandal is made with 100% soy wax and it states that on the label. Also, it is a myth that soywax candles burn cleaner than other types of candles since soot and smoke have to do with the wick, not the wax. (Sometimes the fragrance oils affect smoking).

Vegetable wax candles typically include soy wax and other natural waxes such as palm wax. They are typically paraffin free (such as k. hall and Anthousa). Red Flower is a vegetable and soy wax candle but they do use a touch of paraffin wax. Vegetable wax candles burn beautifully and the container can be washed out with soap and water when finished and reused or recycled (the same is true for soy wax candles).
Beeswax is one of my favorite waxes for it's natural properties and it burns beautifully. It isn't commonly used in scented candles as it doesn't provide fantastic scent throw and it's extremely expensive. We have 100% unscented beeswax pillars and taper candles in our shop, but nothing that is scented at this moment. Palm wax is another natural wax that isn't commonly used but does have beautiful natural properties, especially the way it crystallizes when it hardens. Santuario di Bellezza is a very extravagant 100% palm wax candle.
Paraffin wax is the most widely used wax for candle-making. There are various grades of paraffin wax available. Paraffin wax can be refined so purely that it is used in lip gloss and chocolates. Voluspa candles use this type of food and cosmetic grade paraffin wax. They burn very cleanly and easily and they are our longest lasting candle line. Paraffin wax is commonly used for scented candles because of its ability to provide fantastic scent throw. The most fragrant candle lines in our shop (Votivo, Seda, Tocca, Trapp, Nest Fragrances, Jonathan Adler) use fine grade paraffin wax. Le Cherche Midi, Rigaud and D. L. & Co. use European grade paraffin wax. The wax of a Rigaud candle re-solidifies to the same gorgeous, smooth, shimmery finish that it has when it is new. We've never seen any other candle with that same effect.
DayNa Decker Botanika candles use a resin wax in their translucent candles. They burn cleanly and beautifully.
