Soy Wax vs Paraffin Wax: Which Should You Use?
Share
Soy wax burns cooler and cleaner with a lighter scent throw, while paraffin wax burns hotter with a stronger scent throw and better performance in decorative or carved candles. Neither wax is universally "better" — the right choice depends on whether you're prioritizing a clean-burning container candle or maximum fragrance strength and moldability.
What Is Soy Wax?
Soy wax is made from hydrogenated soybean oil. It's a popular choice for beginner and eco-conscious candle makers because it's renewable, burns at a lower temperature, and produces less soot than paraffin. Soy wax flakes are typically used in container candles — jars and tins — rather than free-standing or carved candles, because pure soy wax is too soft to hold its own shape once removed from a container.
Typical characteristics of soy wax:
- Lower melting point, generally cooler burn
- Lighter, more subtle scent throw compared to paraffin
- Slower burn time in most container candles
- Prone to "frosting" (a white, crystalline surface texture) — a cosmetic effect, not a defect
What Is Paraffin Wax?
Paraffin wax is a petroleum byproduct and has been the standard candle-making wax for over a century. Pure paraffin wax holds detail well, which makes it the preferred choice for pillar candles, carved candles, and molded shapes — including many of the religious and decorative molds sold at Cubicle. It also generally carries a stronger, more consistent scent throw than soy.
Typical characteristics of paraffin wax:
- Higher melting point, firmer finished candle
- Stronger, more consistent scent throw
- Holds fine detail in molded and carved candles
- Widely available and generally lower cost per batch
Side-by-Side Comparison
| Soy Wax | Paraffin Wax | |
|---|---|---|
| Best for | Container candles, jars, tins | Pillar, carved, and molded candles |
| Scent throw | Lighter | Stronger |
| Burn temperature | Cooler | Hotter |
| Detail retention | Poor (too soft) | Excellent |
| Eco-profile | Renewable, plant-based | Petroleum-based |
Our Recommendation for Beginners
If you're making your first candles in jars, start with soy wax flakes — it's more forgiving of small measurement errors and easier to work with at lower temperatures. If your goal is a molded or carved candle (including religious, seasonal, or decorative shapes), pure paraffin wax will give you a cleaner, more detailed result and a longer shelf-stable shape.
FAQ
Can I mix soy wax and paraffin wax together?
Yes, wax blends combining both are common and aim to balance soy's clean burn with paraffin's stronger scent throw and firmer structure.
Which wax is better for scented candles?
Paraffin generally holds and releases fragrance oil more strongly, but soy wax can still carry a good scent throw if fragrance load and wick size are matched correctly.
Why does my soy candle have a white, uneven top?
This is called frosting, a natural characteristic of soy wax caused by temperature changes as it cools. It doesn't affect burn quality or scent.
Is soy wax more expensive than paraffin?
Pricing varies by supplier, but soy wax is often slightly more expensive per kilogram than standard paraffin wax.
