Soy wax is the go-to choice for most beginner candle makers in the UK — and with good reason. It’s natural, burns clean, holds fragrance beautifully, and is wonderfully easy to work with. If you’re making your first candles at home, soy is where to start.

This guide focuses specifically on working with soy wax. We’ll cover which soy wax to buy, the right temperatures, how to get a strong scent throw, and the quirks you’ll encounter along the way. If you haven’t read our complete beginner’s guide yet, start there for an overview of the full candle making process.
Why Choose Soy Wax?
Soy wax is made from soybean oil, making it a renewable, biodegradable alternative to paraffin (which is petroleum-based). Here’s why it’s ideal for beginners:
It melts at a low temperature (around 45–50°C), which means fewer burns and less equipment needed. It produces virtually no soot when burned with the right wick. It has excellent fragrance-holding capacity — most soy waxes handle 8–10% fragrance load comfortably. And it cleans up with just soap and warm water, which is a huge plus when you’re learning.
The main trade-off compared to paraffin wax is that soy can be prone to frosting (a white crystalline pattern on the surface) and doesn’t hold colour as vibrantly. Neither of these affects how the candle burns or smells — they’re purely cosmetic.
Which Soy Wax to Buy in the UK
The UK candle making community primarily uses a handful of trusted soy wax brands. Here are the main ones to look for:
Golden Wax 464 is the most popular soy container wax worldwide. It’s specifically formulated for container candles (jars and tins), gives a smooth top, and has good fragrance retention. Available in 1–5kg bags on Amazon UK. This is what we recommend for beginners.
Nature Wax C3 is another excellent container soy wax with a creamy, opaque finish. It’s slightly harder than GW464, which some makers prefer for a cleaner look.
Golden Wax 494 is designed specifically for wax melts rather than container candles. If you want to make wax melts, this is the wax to choose.

Soy Candle Making: Step by Step
Prepare Your Workspace
Cover your work surface with newspaper or a silicone mat — spilled wax is much easier to peel off than scrub off. Have your containers, wicks, fragrance oil, thermometer, and scale ready before you start melting. Preparation is everything with soy candles.
Melt the Wax
Weigh your soy wax flakes and melt them using a double boiler or electric wax melter. Heat the wax to 80–85°C to make sure all the flakes are fully melted and the wax structure is properly broken down. Stir gently and occasionally. Use a candle making thermometer — don’t guess the temperature.
Add Fragrance at the Right Temperature
This is where many beginners go wrong. Remove the wax from the heat and let it cool to 60–65°C before adding fragrance oil. This temperature range allows the fragrance molecules to bind properly with the soy wax without evaporating.
Add your fragrance at 8–10% of the wax weight. For 200g of wax, that’s 16–20g (roughly 16–20ml) of fragrance oil. Stir slowly and continuously for a full two minutes. This stirring time is important — it ensures the fragrance is evenly distributed throughout the wax.
Pour at the Correct Temperature
Let the wax continue cooling to 55–60°C before pouring. This is the sweet spot for soy wax — cool enough to minimise sinkholes and wet spots, but warm enough to flow smoothly into your container.
Pour slowly and steadily. Avoid moving or disturbing the candle while it cools. Soy wax takes 4–8 hours to fully set at room temperature. Don’t put it in the fridge — rapid cooling causes cracking and adhesion problems.
The Second Pour
Soy wax almost always develops small sinkholes around the wick as it cools — this is completely normal. Once the first pour has fully hardened, poke 2–3 relief holes around the wick with a cocktail stick or skewer. Re-melt a small amount of wax, let it cool to 60°C, and pour a thin top-up layer to fill the holes and create a smooth finish.
Getting a Strong Scent Throw
Scent throw is the term candle makers use for how strongly a candle smells. “Cold throw” is the scent when unlit; “hot throw” is the scent when burning. Here’s how to maximise both with soy candles:
Cure for at least one week. This is the single biggest factor. Fresh soy candles have a weak scent throw because the fragrance hasn’t fully bonded with the wax. After 7–14 days of curing, the difference is remarkable.
Use the right fragrance load. For most soy waxes, 8–10% is the sweet spot. Going above 10% doesn’t make the candle smell stronger — it can actually cause problems like fragrance oil seeping or poor burns.
Choose quality fragrance oils. Not all fragrance oils are created equal. UK-based suppliers like Nikura make oils specifically formulated for candle making, which perform much better than generic craft oils.
Use the correct wick size. An undersized wick creates a small melt pool that doesn’t release enough fragrance. Make sure your wick creates a full melt pool that reaches the edges of the container. Our wick guide explains sizing in detail.
Common Soy Wax Issues
Frosting: A white crystalline pattern on the wax surface. This is natural and unavoidable with soy wax — it’s actually proof that your wax is natural soy. It doesn’t affect the candle’s performance. Learn more in our frosting guide.
Wet spots: Gaps between the wax and the glass where the wax has pulled away. Pouring at a lower temperature (55°C) and warming your jars slightly before pouring helps minimise these.
Sinkholes: Depressions around the wick after cooling. Fixed with a second pour as described above. Read more in our sinkhole troubleshooting guide.
Tunnelling: If the candle burns down the centre without melting to the edges, the wick is too small. See our tunnelling fix guide for solutions.
