Soy Wax vs Paraffin Wax: What's the Difference?

When you're buying a candle, it's easy to focus on the scent.

Lavender, peppermint, tangerine or something warm and spicy. You find a scent you like, light it at home and enjoy it.

But have you ever stopped to think about the wax inside your candle?

The type of wax used can influence how a candle performs, including its texture, appearance, scent release and burning characteristics.

Two common options are soy wax and paraffin wax. Both are used to make candles, but they come from different sources and have different characteristics.

At Sea Zen, we use natural soy wax in our handmade candles. Here's a closer look at the differences and what they mean when you're choosing a candle.

What is soy wax?

Soy wax is made from soybean oil. The oil is processed and hydrogenated to create a wax that can be used in candle making.

It's popular with candle makers who want to use a plant-derived wax in their products.

Soy wax can work well in container candles, although the finished candle's performance depends on the particular wax blend, wick, fragrance or essential oil, and container.

It can also have a different appearance from other waxes, sometimes developing a naturally creamy or slightly textured surface.

What is paraffin wax?

Paraffin wax is derived from petroleum refining.

It's widely used in candle making and has been used for many years because of its versatility and established performance in different candle formulations.

Depending on the formulation, paraffin candles can offer strong scent release and a consistent finish.

Like soy wax, the way a paraffin candle burns depends on factors such as the wick, container and overall design.

Neither wax guarantees a perfect candle on its own. The finished product matters just as much as the ingredient.

Soy wax vs paraffin wax: the main differences

1. Where they come from

Soy wax is derived from soybean oil, while paraffin wax is derived from petroleum refining.

If you prefer plant-derived ingredients, soy wax may be more aligned with your preferences.

2. How they burn

Both types of wax can be used to make well-performing candles.

Burn time and flame behaviour depend on the candle's size, wick, formulation and how it's used. You shouldn't assume a soy candle will always burn longer than a paraffin candle.

3. Scent performance

Both waxes can carry fragrance, but scent strength varies depending on the formulation.

The type of wax is only one part of the equation. The wick, oil selection, concentration and candle design also play a role.

4. Appearance

Soy wax often has a creamy finish, while paraffin wax can be formulated to create a range of appearances and textures.

Neither appearance is automatically an indication of quality.

5. Environmental considerations

Soy wax is plant-derived, but that doesn't automatically mean every soy candle has a lower environmental impact.

Factors such as agricultural production, land use, processing, packaging and transport all matter. Paraffin is petroleum-derived, but a fair comparison needs to consider the wider product lifecycle rather than just one ingredient.

If sustainability matters to you, look at the whole product and how it's made.

Is soy wax better than paraffin wax?

That depends on what you're looking for.

If you prefer a candle made with plant-derived wax, soy wax may be the better fit for you.

If your priority is a particular scent performance or finish, it's worth considering the complete formulation rather than choosing based on wax alone.

It's also important not to assume that one wax automatically makes a candle non-toxic, healthier or free from emissions. Any burning candle produces combustion by-products, so good ventilation and safe use are important regardless of wax type.

Why we chose soy wax for Sea Zen

When I started making candles, I became interested in the ingredients that went into them.

I wanted to understand the materials I was working with and create something that felt consistent with the direction I wanted Sea Zen to take.

We chose natural soy wax because it fits our approach to making candles: simple, considered and focused on the experience of enjoying a scent at home.

We combine it with pure essential oils to create our range of scents, from lavender and tangerine to peppermint and pine.

Every candle is hand-poured in Dunedin, New Zealand.

It's a process that takes care, experimentation and attention to detail. The ingredients matter, but so does the finished candle.

What should you look for when buying a candle?

Rather than focusing on wax alone, consider the whole product.

• Ingredients: Look for clear information about the wax and the oils or fragrances used.
• Burn instructions: A good candle should come with clear guidance on safe use.
• Wick and container: These need to be appropriate for the candle's design.
• Scent: Choose something you'll genuinely enjoy having in your space.
• Transparency: Look for a maker who can explain how their products are made.

The right candle is the one that suits you

There isn't a single wax that makes every candle the best.

Soy wax and paraffin wax each have different origins and characteristics, and both can be used to make candles people enjoy.

For us at Sea Zen, soy wax was the right choice for the kind of candles we wanted to create.

We want our products to feel thoughtful, natural and easy to enjoy as part of everyday life.
