Wax melts have become increasingly popular as a safe and convenient way to add fragrance to a room, but some people have experienced crumbling issues with their wax melts. Wax melts can crumble or break for several reasons, and here are some of the most common causes:
- Temperature fluctuations: If the wax melts are exposed to temperature fluctuations, such as going from hot to cold, they can become brittle and crumble easily.
- Improper storage: If wax melts are stored in an area that is too hot or too cold, it can cause the wax to shrink or expand, resulting in cracking and crumbling.
- Age: Over time, wax melts can lose their elasticity and become more brittle, making them prone to cracking and crumbling.
- Quality of wax: Lower-quality wax melts may be more prone to crumbling than higher-quality melts due to differences in the wax blend or additives.
- Mold release: If wax melts are not properly released from the mold, they may become damaged and crumble easily.
Causes of Wax Melts to Crumble
Wax melts are a popular alternative to traditional candles, but they can be frustrating when they crumble. There are several reasons why wax melts may crumble, including temperature fluctuations, incorrect pouring temperature, using the wrong type of wax, using too much fragrance oil, and not adding additives.
Wax melts are sensitive to temperature fluctuations, which can cause them to crumble. The wax can become brittle and break apart if exposed to extreme heat or cold. Storing wax melts in a cool, dry place away from direct sunlight and heat sources is important.
Incorrect Pouring Temperature
Another common reason wax melts may crumble is incorrect pouring temperature. If the wax is poured at too high of a temperature, it can cause the wax to shrink and crack once it cools. Conversely, if the wax is poured at a low temperature, it may only partially adhere to the mold and break apart when unmolded.
Using the Wrong Type of Wax
Not all waxes are created equal, and using the wrong type of wax can cause wax melts to crumble. Some waxes are designed specifically for candles and may need the necessary additives to make them suitable for wax melts. Be sure to choose a wax that is specifically formulated for wax melts.
Using Too Much Fragrance Oil
While fragrance oils are, an essential part of wax melts, using too much can cause them to crumble, according to the Eco Candle Project. Fragrance oils can weaken the structure of the wax, making it more prone to breaking apart. Be sure to follow the recommended fragrance oil ratio for your specific wax.
Not Adding Additives
Additives, such as stearic acid or cyber, can help improve the structure and scent throw of wax melts. These additives are necessary for wax melts to be more prone to crumbling. Be sure to add the recommended amount of additives for your specific wax.
Tips to Prevent Wax Melts from Crumbling
Using the Right Wax
Choosing the right wax is crucial in making wax melts that don’t crumble. Some waxes are more brittle than others and tend to crack and crumble when unmolded. To prevent this, use a wax formulated for making wax melts or tarts.
Soy wax, beeswax, and paraffin wax are popular choices. Soy wax is known for its excellent scent throw, while beeswax is known for its natural, golden color. Paraffin wax is the most commonly used wax for making wax melts, and it is known for its smooth and creamy texture.
Measuring Fragrance Oil Correctly
Adding too much or too little fragrance oil can cause wax melts to crumble. Measuring the fragrance oil correctly ensures the scent is strong enough but not overpowering. The general rule of thumb is to use one ounce of fragrance oil per pound of wax. However, some fragrances may require more or less oil. Always check the manufacturer’s recommendations for your specific fragrance oil.
Additives such as stearic acid, cyber, and microcrystalline wax can improve the texture and scent throw of wax melts. Stearic acid can make the wax harder and less brittle, while cyber can improve the scent throw. Microcrystalline wax can improve the texture and help the wax melt more evenly. However, adding too many of these additives can cause the wax to crumble. Always follow the manufacturer’s recommendations for the number of additives to use.
Pouring at the Correct Temperature
Pouring wax at the correct temperature prevents wax melts from crumbling. If the wax is too hot, it can cause the fragrance oil to evaporate, resulting in a weak scent. If the wax is too cold, it can cause wax to crack and crumble. The ideal pouring temperature for most waxes is between 150°F and 160°F. Always check the manufacturer’s recommendations for the specific wax you are using.
Storing Wax Melts Properly
Based on observation, wax melts are sensitive to light and temperature, and storing them improperly can cause them to crumble. Store wax melts in a cool, dry place away from direct sunlight. Avoid storing them in the fridge or freezer, as this can cause them to crack and crumble. Please keep them in their clamshells or back in the sealed packaging dispatched to you to keep them dust-free.
