Candle Wax Types Explained

Soy is a vegetable wax with a low melting point, roughly 45 to 52°C. That low melt point is the source of all its characteristics: it burns cooler, consumes wax more slowly and produces very little soot, so the glass stays clear and the burn time is long for the volume.

The trade-off is scent throw. Cooler wax releases fragrance less aggressively, so a soy candle in a large room can feel underpowered next to a paraffin one. Brands compensate with higher fragrance oil loads. Le Labo pours in 100% soy and offsets the throw with a generous oil concentration.

Soy is also prone to frosting, the white crystalline bloom that appears on the surface. It is purely cosmetic and is in fact a sign the wax has not been blended with paraffin.

Coconut wax has become the artisan default over the last decade, usually blended with rapeseed or soy because pure coconut wax is too soft to hold a shape. The blend burns as slowly as soy while carrying fragrance considerably better, which makes it the best all-round performer for most rooms.

It is more expensive than soy or paraffin, which is why it appears mostly in artisan and independent brands rather than in mass-market ranges. Lumond built its top ranking partly on this blend, achieving 60 to 80 burn hours with a full, even melt pool and no paraffin.

Paraffin is a petroleum by-product and remains the strongest performer on pure scent throw. It has a higher melting point, holds a large volume of fragrance oil and releases it fast, which is why the candles you can smell from the next room are almost always paraffin or paraffin-blended.

The costs are a hotter burn, faster wax consumption, more visible soot and a petroleum origin that sits awkwardly with sustainability claims. Nest New York uses a paraffin-based blend and is the strongest thrower in our ranking as a direct result. Many French houses use paraffin within their proprietary "vegetal blend" formulations without stating the proportion.

Beeswax burns longer and cleaner than anything else, with a very high melting point and negligible soot. Unscented beeswax gives off a faint natural honey aroma, and it is the traditional wax for candles where no added fragrance is wanted.

It is poorly suited to scented candles: the dense wax structure resists fragrance oil and the natural honey note interferes with delicate compositions. It is also expensive and, being an animal product, unsuitable for vegan buyers.

For a large or open-plan room where throw matters most, a paraffin blend will outperform everything else. For a bedroom or study where you want a long, clean, slow burn, soy or a coconut blend is the better answer. For the best balance of the two, a coconut and rapeseed blend is the strongest all-round choice and the reason artisan brands have converged on it.
