Wax Melt Supplies

Melt waxes are formulated to release fragrance effectively when warmed to wax burner temperatures - typically from a tea light or electric burner - rather than to hold a wick and sustain a flame. They are generally softer and lower in melting point than pillar wax, which allows them to pool fully in a burner and release scent cleanly. Container candle wax used in melts typically gives inferior throw because the formulation is optimised for a different heat exposure profile.

Soy melt waxes - such as Golden Wax 494 - have a plant-derived origin suited to brands with natural positioning. Paraffin-containing blends like HPM typically deliver stronger, crisper scent throw and a harder snap finish. Many makers use a soy-paraffin blend like HPM to get the performance benefits of both. The decision is partly technical and partly a brand positioning choice - both perform well at the correct fragrance load.

A clean snap finish comes from waxes with a harder, more brittle set. HPM Blend (soy and paraffin) and Golden Wax 494 (100% soy) both give a firm snap. Fully natural waxes like RCX Melt Blend have a softer set and may not produce the same clean break, but suit brands where plant-based origin matters. The trade-off is generally between snap and natural credentials rather than between snap and scent throw.

Wax melts can typically carry a higher fragrance load than container candles because there is no wick performance to manage. Most dedicated melt waxes support 8-12% fragrance by weight, and working toward the upper end of the wax's stated range maximises cold and hot throw. The ceiling is set by the wax's physical binding capacity - candles and wax melts share the same IFRA category, so there is no additional IFRA restriction to check beyond what applies to candles. The limiting factor is simply what your wax can hold without bleed.

Most dedicated melt waxes support 8-12% fragrance by weight. The ceiling is set by the wax's physical loading capacity and the IFRA maximum for the wax melt category. Working toward the upper end of the wax's stated range gives the strongest cold and hot throw. Going beyond the stated maximum causes fragrance bleed regardless of how carefully you add the oil or at what temperature.

Strong melt throw comes from three things working together: fragrance load at or near the wax's maximum binding capacity; a melt-specific wax formulated for efficient fragrance release at wax burner temperatures; and a burner that reaches the correct operating temperature to pool the wax and vaporise the scent fully. Melt throw is generally more intense than candle throw because there is no combustion competing with fragrance vaporisation and the full wax surface is exposed to the heat source.

Yes - candles and wax melts share the same IFRA category, so there are no additional restrictions to navigate between the two. One practical advantage of wax melts is that the fragrance never reaches combustion, which opens up options that would not work in a candle. Essential oils and more delicate blends that burn off or behave unpredictably in a flame can perform perfectly well in a melt warmed by a tea light or electric burner. This makes wax melts a useful format for fragrance types that are difficult to wick reliably.

Fragrance bleed - oil pooling on the surface or seeping from the solid melt - is most commonly caused by exceeding the wax's maximum load, adding fragrance at too low a temperature so it fails to bind properly, or using a fragrance with a high proportion of components the wax cannot fully absorb. Rapid temperature change is also a cause: melts stored in cold conditions and then brought into a warm room can sweat fragrance out of the wax. This will often reabsorb as the temperature normalises, but not always. Reduce the fragrance percentage to within the stated range and check your addition temperature first. If bleed continues at a compliant load, the specific wax and fragrance combination may not be compatible.

No. Purpose-made melt waxes are engineered specifically for wax melt applications and come ready to use - no additives needed. Adding additives to a pre-formulated melt wax risks disrupting the scent throw, texture, and surface finish the blend was designed to deliver. If you want to adapt a standard container wax for melt use, stearic acid can be added to increase hardness and improve snap. That said, starting with a dedicated melt wax is always the simpler and more predictable route.

Melt waxes are not suitable for container candles - the hardness and adhesion profile is wrong and they will not adhere properly to glass. They are generally too soft for freestanding pillar candles. HPM Blend is an exception given its harder formulation and is suited to both melts and pillars. As a general principle though, trying to find one wax that works across multiple product formats is rarely a good strategy. Each product type performs best when the wax, fragrance and wick - or in the case of melts, the wax and fragrance - are optimised specifically for that application. Handmade products should outperform mass-produced equivalents on quality, and that comes from fine-tuning rather than generalising.

Yes. Wax melts are subject to the same CLP labelling requirements as candles and reed diffusers. If the finished product contains classified hazardous substances above the relevant concentration thresholds - which most fragranced melts do - the label must carry the required hazard pictograms, signal words and responsible party details. The label must reflect your actual fragrance usage level at the concentration you produce, not a generic template.
