How Much Fragrance Oil Should I Add?

The world of candle making is equal parts art and science. Whether you're a beginner hobbyist or a growing brand, the heart of your operation is your wax melter. A high-quality melter ensures even heat distribution, preserves fragrance integrity, and boosts your production efficiency.

But with so many models on the market, how do you choose? And once you have your melter, a critical question arises: How much fragrance oil should I add?

This comprehensive guide will walk you through everything you need to know, featuring a detailed comparison of professional wax melting pots to help you make an informed decision.

Why a Dedicated Wax Melter is a Game-Changer

Ditching the double boiler for a dedicated wax melter was the best decision I made for my candle business. Here’s why:

Precise Temperature Control: Prevents scorching, which can ruin your wax and destroy delicate fragrance notes.

Efficiency: Melt large batches at once, saving you immense time and energy.

Safety: Designed with melting wax in mind, they are far safer than makeshift setups.

Consistency: The key to a professional product is batch-to-batch consistency, which a good melter provides.

How Much Fragrance Oil Should I Add? The Golden Rule

This is the most common question for a reason! Getting the ratio wrong can lead to poor scent throw or even oil seeping out of the candle (a problem called "frosting" or "sweating").

The industry standard is a fragrance load of 6% to 10%. This means for every pound of wax, you add 0.96 to 1.6 ounces of fragrance oil.

For a 10% Load: 1.6 oz of fragrance oil per 1 lb of wax.

For an 8% Load: 1.28 oz of fragrance oil per 1 lb of wax.

For a 6% Load: 0.96 oz of fragrance oil per 1 lb of wax.

Pro Tip: Always check the manufacturer's recommendations for your specific wax and fragrance oil. Some waxes have a maximum load they can hold. I always recommend starting at 8% and testing from there. Always use a scale for accuracy—volume measurements are not reliable for this!

3 Pro Tips for Using Your Wax Melter

Preheat Your Melter: Turn it on before you add wax. This helps the wax melt evenly and prevents a hard layer from forming on the bottom.

Melt to the Right Temperature: Heat your wax to the temperature recommended by your wax manufacturer (usually between 175-185°F or 79-85°C) before adding fragrance oil.

Stir, Stir, Stir! After adding your fragrance oil at the correct temperature, stir gently but thoroughly for at least two minutes to ensure the oil is fully emulsified into the wax.

Investing in the right wax melter is the first step toward creating a successful, scalable candle business. By understanding your needs and matching them to the right machine—like the reliable range from ToAuto—and mastering the fundamentals like fragrance load, you’re setting yourself up for success.
