Candle wax types compared
Soy, beeswax, coconut, rapeseed and paraffin wax all burn differently. This guide compares how each one is made, how it smells, how long it lasts and what it is best for.
Why the wax matters
Wax is the fuel of a candle. When you light the wick, the heat melts the wax near the flame. The liquid wax travels up the wick, turns into vapor and burns. The type of wax changes how fast that happens, how much fragrance the candle can hold, how the surface looks once it sets and how much wax is left behind as a hard wall that never melted.
No wax is perfect. Each one is a trade-off between scent throw, burn time, appearance, price and where the raw material comes from.
The main waxes at a glance
| Wax | Made from | Melt point | Scent throw | Burn | Best for |
|---|---|---|---|---|---|
| Soy | Hydrogenated soybean oil | Low to medium | Good, gentle | Slow and even in a container | Container and jar candles |
| Beeswax | Honeycomb wax made by bees | High | Light honey smell of its own | Long, bright flame | Pillars, tapers, unscented candles |
| Coconut | Hydrogenated coconut oil, usually blended | Low | Very good | Slow, creamy pool | Luxury container candles |
| Rapeseed | Hydrogenated rapeseed (canola) oil | Low to medium | Good | Slow | Container candles, often blended |
| Paraffin | By-product of petroleum refining | Varies by grade | Strong | Fast, easy to wick | Pillars, votives, bright colors |
Soy wax
Soy wax was developed in the 1990s as a plant-based alternative to paraffin. It is soft, so it works best poured into a container, where the glass holds it in shape. It melts at a fairly low temperature, which helps it form a wide melt pool and release fragrance gently.
Soy is known for a creamy, matte look. It can also show "frosting", a white crystal bloom on the surface or along the sides of the jar. Frosting is natural and does not affect the burn. Many small-batch makers use soy or a soy blend because it pours cleanly and burns slowly.
Beeswax
Beeswax is one of the oldest candle waxes. It has a high melting point, so beeswax candles burn slowly and hold their shape well enough for tall pillars and tapers. It has its own soft honey scent and a natural golden color, which is why it is often sold unscented. Beeswax costs more than plant waxes because supply is limited by what hives produce.
Coconut wax
Coconut wax is usually blended with soy or another wax to make it firm enough to use. It is prized for strong scent throw and a smooth, white surface, but it costs more than most other waxes.
Rapeseed wax
Rapeseed wax is a plant wax popular in Europe, where the crop is grown widely. It behaves a lot like soy and is often blended with it.
Paraffin wax
Paraffin has been the most common candle wax since the late 1800s. It is cheap, holds color and fragrance very well and comes in many hardness grades for different candle styles. Its downside for many shoppers is that it comes from petroleum. Claims that paraffin is much less healthy to burn than plant waxes are not backed by strong evidence. What matters more for indoor air is a trimmed wick, good ventilation and not burning candles for many hours at a time.
Blends
Many modern candles use blends, such as soy with coconut or soy with a little paraffin. Blending lets makers balance hardness, scent throw and looks. If a label says "soy blend", it means soy plus at least one other wax.
Whatever the wax, the first burn sets the pattern for the life of the candle. Read first burn and the memory ring before you light a new jar.
How to choose
- Want a slow, gentle burn in a jar: choose soy or a soy blend.
- Want a strong scent in a big room: look at coconut blends.
- Want a classic unscented pillar: choose beeswax.
- Want bold colors on a budget: paraffin does the job.
