Why Create a Custom Wax Blend?

While single-ingredient waxes like 100% Soy are great, professional candle makers formulate their own "house blends" to combine the best properties of different waxes. A unique house blend gives you a competitive edge that cannot be easily copied.

Top 3 Wax Blend Recipes

Use these industry-standard ratios as a starting point for your experiments:

1. "Parasoy" (70% Soy / 30% Paraffin)

The industry favorite. Soy provides a clean burn and marketing appeal, while the Paraffin stabilizes the structure, prevents frosting (white spots), and drastically improves the hot scent throw.

2. Luxury Coco (80% Coconut / 20% Soy)

Coconut wax has incredible scent throw but is very soft (it can melt in a hot truck). Blending in 20% Soy raises the melting point enough to make it shippable.

3. The Hardener (90% Soy / 10% Beeswax)

Perfect for wax melts and tart shells. Adding just 10% Beeswax instantly hardens the soy, allowing it to release cleanly from silicone molds without crumbling.

🔥 The Golden Rule of Blending

Always melt the wax with the higher melting point first! For example, when making Parasoy, melt the Paraffin fully until liquid, then add the Soy wax. This ensures they bind together correctly without separation.

How to Test a New Blend

Blending waxes changes how the candle burns. Follow this simple testing checklist:

Step 1: Small Batch

Make a 100g Test Batch

Do not make a full case immediately. Use the calculator above to mix a tiny amount for just one or two candles.

Step 2: Wick Calibration

Re-Calibrate Your Wick

If adding Paraffin, you can likely use a smaller wick (Wick Down). If adding Beeswax, you must use a larger, hotter wick (Wick Up).

Step 3: The Cure

Cure for 1 Week

Different waxes bind at different speeds. Let the blend sit for at least 7 days before lighting to test the true scent throw and structure.

Frequently Asked Questions

What is the best ratio for Parasoy?
The most common "Parasoy" ratio is 70% Soy to 30% Paraffin. This ratio keeps the candle mostly natural (for marketing) while gaining the scent throw and smooth tops of paraffin.
Which wax blend has the best scent throw?
Generally, Paraffin blends offer the strongest "hot throw" (scent while burning). However, a Coconut/Soy blend (80/20) is widely considered the best natural alternative, offering a superior scent throw compared to 100% Soy.
How do I harden soy wax for molds?
To harden soy wax for pillars or silicone molds, blend in 10% to 20% Beeswax or Stearic Acid. This raises the melting point and makes the wax more durable and easier to demold.
How do I calculate wax blend percentages?
To calculate manually: Multiply your Total Batch Weight by the decimal percentage. For a 70% blend in a 1000g batch, multiply 1000 x 0.70 to get 700g. Our calculator above does this math instantly for any batch size.
Do I need to change my wick when blending waxes?
Yes. Paraffin burns easier than soy, so adding paraffin might allow you to use a smaller wick. Conversely, Beeswax is very hard to burn, so adding beeswax usually requires sizing up to a larger, hotter wick.
