Key Takeaways - Why the crumbling ?

  • Wax melts can crumble due to temperature changes, so it's best to keep them in a place where the heat and cold are consistent.
  • Using too much oil in your wax melts can make them weak and cause crumbling; always measure carefully and follow guidelines.
  • Crumbling of wax melts is also avoided by storing them properly; choose a cool, dry area away from sunlight or dampness to protect their shape and scent.


Causes of Crumbling Wax Melts

Changes in temperature can cause wax melts to become brittle and crumble, while a high oil content can also lead to crumbling.

Changes in temperature

Wax melts can become vulnerable to crumbling if they experience frequent or severe temperature fluctuations. Warm conditions might cause the wax to soften, while colder temperatures can make it brittle and more prone to breaking apart.

This sensitivity results from the natural properties of soy wax, commonly used in making wax melts. To maintain a smooth and consistent texture, it is crucial to keep your wax melts in a stable environment where heat and cold are controlled.

Avoid placing your wax melt storage near windows, radiators, or air conditioners where sudden temperature changes are likely. Consistency is key; find a cool, dry place that stays at a relatively constant temperature year-round.

By doing so, you reduce the risk of the melted wax consistency becoming too soft or hard which then leads to issues with crumbling when you're ready to use them again.

High oil content

High oil content in wax melts can lead to crumbling. To prevent this issue, consider adjusting the oil content in your wax melt recipe. Be mindful of the proportion of fragrance or essential oils added to ensure that it does not exceed recommendations for optimal performance.

When adjusting oil content, carefully balance the amount used and consult guidelines specific to the type of wax being utilised. It's vital to strike a harmonious blend that enhances scent throw without compromising the structural integrity of your wax melts.

By making adjustments to achieve an ideal oil-to-wax ratio, you can create sturdy and long-lasting wax melts.

Solutions to Prevent Wax Melts from Crumbling

To prevent wax melts from crumbling, proper storage methods such as keeping them away from direct sunlight and extreme temperature changes are essential. It is also important to adjust the oil content in the wax melts to achieve a smoother texture and prevent crumbling.

Proper storage methods

To maintain the integrity of your wax melts, store them in a cool, dry place away from direct sunlight and extreme temperature changes. A cupboard or drawer is an ideal storage location to protect the melts from moisture and temperature fluctuations.

When exposed to sunlight or high temperatures, wax melts can soften or melt slightly, resulting in a change in texture and fragrance strength. Additionally, ensure that the packaging is properly sealed to prevent exposure to air and moisture which could cause crumbling or loss of scent.

Adjusting oil content

After addressing proper storage methods, another key factor to consider for preventing wax melts from crumbling is adjusting the oil content. To maintain the structural integrity of your wax melts, it's essential to find the right balance in oil content.

Too much oil can lead to a softer texture, making the wax prone to crumbling and breaking. On the other hand, insufficient oil may result in dry and brittle wax melts that are also susceptible to crumbling.

Adjusting the oil content involves carefully measuring and experimenting with different ratios until you achieve a consistency that holds together without being overly greasy. It's crucial to follow recommended guidelines for fragrance oils and additives while making adjustments in order to avoid compromising the quality of your wax melts.


To prevent wax melts from crumbling, store them in a cool, dry place away from direct sunlight and temperature fluctuations. Adjust the oil content when making your wax melts to achieve the right balance for a smooth texture.

Proper storage methods and tweaking the oil content will help maintain the integrity of your wax melts.


1. Why do my wax melts start to crumble when I use them?

Your wax melts might crumble due to a range of issues like improper storage, using the wrong type of soy wax in your homemade candles, or candle making problems linked with temperature during the setting process.

2. What should I do if my wax melt has clumps or uneven texture?

If you have clumpy soy wax, it's often a sign that something went wrong during melting or there are issues with your wax melt mould. Following precise melting instructions and checking your moulds can help solve this problem.

3. Can storing my wax melts incorrectly cause any problems?

Yes! Proper wax melt storage is essential as exposure to heat and light can degrade the quality causing crumbling or discolouration over time, affecting both their appearance and fragrance throw.
