How to Make Strong-Smelling Wax Melts with Fragrance Oils: Tips, Ratios & FAQs
If you're making wax melts at home or just curious about how we at Aroma Ninjas craft our signature strong-scented snap bars, this guide is for you. We’re answering some of the most frequently asked questions around using fragrance oils in wax melts, including how much to use, the difference between essential and fragrance oils, and how to make your wax melts smell as strong as possible.
Can I Use Fragrance Oils in Wax Melts?
Yes, fragrance oils are the most popular and effective choice for making wax melts. Unlike essential oils, which are natural plant extracts, fragrance oils are often synthetically enhanced to create long-lasting, complex scents that perform beautifully when melted.
At Aroma Ninjas, we use high-quality, wax-compatible fragrance oils that are specifically designed for home fragrance products, ensuring great scent throw and a lasting aroma.
Is Fragrance Oil Better Than Essential Oils in Wax Melts?
This depends on your goals, but for most wax melt makers, the answer is yes.
Why fragrance oils are often better:
-
Stronger scent throw (especially in hot throw – how your wax smells when melted)
-
Wider range of fragrances – think candyfloss, coffee, perfume dupes, etc.
-
More stable when heated, meaning your wax melts won’t lose their scent quickly
Essential oils can be a great natural option, but they tend to be more subtle, expensive, and not all are safe for melting due to their flash points. That’s why fragrance oils are typically the better choice for wax melts.
What Is the Ratio of Fragrance Oil to Wax for Wax Melts?
The ideal fragrance load is typically 6–10% of your total wax weight.
So for every 100g of wax, you would use:
-
6g–10g of fragrance oil
Always check the wax manufacturer’s guidelines for maximum fragrance load – exceeding it can cause issues with melting, curing, or even safety.
What Happens If You Put Too Much Fragrance Oil in a Wax Melt?
Using more fragrance oil than your wax can hold might seem like a shortcut to stronger wax melts – but it can backfire.
Here’s what can happen if you go overboard:
-
Oily, leaky wax that never sets properly
-
Reduced scent throw, as excess oil can block scent diffusion
-
Poor burn quality or even safety hazards like smoking or fire risk in burners
Stick to the correct ratio and allow your melts to cure for 1–2 weeks for best results.
How to Make Strong Smelling Wax Melts
Want wax melts that fill your room with fragrance? Here are our top tips:
-
Use high-quality fragrance oils designed for wax products
-
Choose a wax with good scent throw, like soy or para-soy blends
-
Heat your wax to the correct temperature before adding fragrance (usually 60–70°C)
-
Allow proper curing time – at least 7–14 days before use
-
Store melts properly – cool, dry, airtight containers preserve the scent
What Is the Best Fragrance Load for Wax Melts?
While 6%–10% is common, the best fragrance load depends on:
-
Your wax type
-
The specific fragrance oil used
-
How strong you want the scent to be
Our general rule at Aroma Ninjas is to go as high as safely allowed, usually around 8%–10%, to create a bold, room-filling aroma.
