Why Your Wax Melts Smell Weak - and How to Fix It
Few things are more disappointing than lighting a wax burner and realising the scent is barely noticeable. If you've ever wondered why some wax melts smell weak - or lose their fragrance quickly - the answer lies in the science of wax types, fragrance quality, and melt temperature. Here, we explain what truly affects scent throw and how to enjoy stronger, longer-lasting fragrance every time.
Understanding Scent Throw
"Scent throw" refers to how far and how strongly a fragrance travels once your wax begins to melt. The strength of a wax melt depends on the balance between its wax base, fragrance oil concentration, and melting point. Even small variations can make a significant difference - excessive fragrance can cause separation, while insufficient fragrance can result in a faint or short-lived scent.
Paraffin Wax - Strong but Synthetic
Paraffin wax is derived from petroleum and has long been used for candles and wax melts because it holds fragrance well and offers a strong hot throw. However, it has drawbacks: it burns hotter, can produce soot, and is not considered eco-friendly. Paraffin can overpower delicate notes and, over time, release volatile compounds that many households prefer to avoid. It's cheap and powerful, but not clean or sustainable.
Soy Wax - A Popular Natural Alternative
Soy wax is made from hydrogenated soybean oil and quickly became the go-to for those seeking a "natural" option. It's renewable and burns cleaner than paraffin, but it has a higher melting point - meaning fragrances can sometimes take longer to bloom. Soy melts can also frost (develop a cloudy appearance) and may struggle with consistent scent distribution unless carefully blended. Many quality brands still use soy successfully, but it often requires higher fragrance loads and careful formulation.
Beeswax - Natural but Subtly Scented
Beeswax is another natural option prized for its purity, long burn time, and subtle honeyed aroma. However, it's expensive and has a natural scent that competes with added fragrance oils. This makes it less suitable for creating bold or varied scent profiles. Beeswax melts tend to offer a gentle, background aroma - perfect for relaxation but not ideal if you're looking for a strong, room-filling throw.
Coconut Wax - The Cleanest and Strongest of Them All
Coconut wax is a newer, luxury alternative made from cold-pressed coconut oil. It melts at a lower temperature, meaning fragrance oils release gradually and evenly for hours of consistent scent. Unlike soy or beeswax, it doesn't carry a natural aroma that interferes with the fragrance itself. It's smooth, sustainable, vegan-friendly, and offers an exceptional scent throw without overheating or releasing toxins.
Tillybell uses 100% pure coconut wax, hand-poured in County Durham and blended with high-grade UK fragrance oils. This gives every bar a balanced performance - clean, even melting and long-lasting scent strength that transforms your space without overpowering it.
Other Factors That Affect Scent Throw
Even the best wax can underperform if other elements aren't right. Here's what else matters:
- Fragrance quality: Cheap oils fade quickly. Look for IFRA-certified blends like those used by Tillybell.
- Curing time: Wax melts need time to bind with the fragrance. Many waxes perform best after curing for at least 7-10 days.
- Burner temperature: Electric burners with low heat or tealight burners placed too high can limit scent release. Select a stable burner that is suitable for your wax type.
- Room size and airflow: Strong airflow or vast spaces can dilute scent quickly - try closing doors for a more concentrated aroma.
How to Make Wax Melts Smell Stronger
If your melts aren't performing, try these quick fixes:
- Use your burner correctly - right dish size, proper tealight or electric heat level.
- Start with a clean burner - residue from old melts can weaken scent throw.
- Store melts in a cool, dark place to preserve fragrance oils.
- Experiment with different fragrance families - spicy and woody scents often project stronger than delicate florals.

Wax Melt FAQs
Do wax melts lose their scent over time?
Yes - over time, fragrance oils can slowly evaporate or break down, especially if melts are stored in warm or bright environments. To preserve scent, keep your Tillybell wax melts in a cool, dark place and use them within six months for the richest aroma.
Which type of wax gives the best scent throw?
Coconut wax generally delivers the best scent throw thanks to its low melting point and smooth texture. It releases fragrance evenly and cleanly, outperforming paraffin, soy, and beeswax for both hot and cold scent projection. It's also vegan, sustainable, and toxin-free - ideal for modern homes.
Can I mix different wax melt scents together?
Yes - blending scents can create beautiful custom fragrances, but make sure your burner isn't overfilled. Start with compatible families such as floral and fruity, or woody and spice. Tillybell melts are formulated to blend well without overpowering each other.
Why does my wax melt smell strong at first but fade quickly?
That often happens with lower-quality wax or oils. Some brands use high-fragrance bursts that fade as the melt overheats. Coconut wax melts, such as those from Tillybell, release fragrance gradually, maintaining consistency and strength over time.
Are wax melts safe to use around children and pets?
Yes - provided you use clean, toxin-free melts and keep burners out of reach. Tillybell uses vegan, cruelty-free ingredients and IFRA-certified oils, making our melts a safer, cleaner choice for homes with children and pets.
