Candles are made from different types of wax, such as coconut, soy, paraffin, or beeswax, and the melting point of a candle depends on the type of wax it is made from. Coconut and soy wax, for example, have lower melting points than paraffin wax, with melting points between 49°C and 54°C. On a hot day, the temperature inside a parked car can reach 71°C, so it is likely that candles will melt if left in a hot car, especially during the summer months. However, there are ways to prevent candles from melting in a hot car, such as wrapping them in kitchen plastic wrap and placing them in a cardboard box, or using additives to harden the wax.

Candles in hot cars: melting points
Candles are made from different types of wax, and various waxes melt at different temperatures. For example, coconut and soy waxes usually melt at temperatures between 49°C and 54°C, while paraffin wax melts between 99°F and 130°F, and beeswax has a higher melting point of 145°F. The temperature inside a car can quickly soar above these levels, especially during the summer months, and so candles are susceptible to melting inside hot cars.
The melting point of a candle depends on its size, type, and the wax it is made from. Smaller candles tend to melt faster than larger ones, and pillar candles may melt in their packaging. Candles made from softer waxes, such as soy wax, are more likely to melt in a hot car than harder waxes like beeswax.
If a candle melts inside a car, it can be salvaged by carefully removing the container and allowing the wax to cool and solidify. However, if a candle is left in a hot car for an extended period, it may suffer damage. The fragrance oil may separate from the wax and pool on top, creating a fire hazard. Conversely, leaving candles in a cold car can also cause issues, as the wax may shrink and pull away from its container.
To prevent candles from melting in a hot car, they can be wrapped in kitchen plastic wrap and placed in a cardboard box. Cardboard is a great insulator and will help keep the candles cool. Alternatively, additives can be used to harden the wax and increase its melting temperature. Palm stearic acid or universal additives can be used, or waxes with higher melting points, such as palm, paraffin, or beeswax, can be chosen.

Preventing candle melting in hot cars
Candles are prone to melting in hot cars due to the high temperatures inside the vehicle. The temperature inside a parked car can reach 71°C (160°F), which is much higher than the melting points of various types of wax commonly used in candles. For example, coconut and soy wax typically melt between 49°C (120°F) and 54°C (130°F). Therefore, it is important to take precautions to prevent candle melting if you need to store or transport them in a car.
One way to prevent candle melting in a hot car is to choose candles made from waxes with higher melting points. Harder waxes like palm, paraffin, or beeswax can withstand higher temperatures compared to softer waxes like soy, coconut, or apricot wax. If you prefer candles made from softer waxes, consider blending them with harder waxes to increase the melting point. For instance, you could try a combination of 30% beeswax and 70% soy wax to make your candles harder and less susceptible to melting.
Additionally, you can add certain additives to your wax to increase its melting point. Additives such as palm stearic acid or universal additives can raise the temperature at which the wax melts. However, keep in mind that using too many additives may affect the colour, scent, and burn properties of your candle.
Another effective way to prevent candle melting in a hot car is to ensure proper storage and packaging. Store your candles in a cool place or airtight container out of direct sunlight before placing them in your car. When transporting candles, wrap them in kitchen plastic wrap, which doesn't absorb heat, and then place them in a cardboard box. Cardboard is a great insulator and will help keep your candles cool. Avoid using wax paper, as it is not heat-resistant, and will melt along with your candles.
Lastly, if you are shipping candles to customers, try to deliver them as quickly as possible to minimise the time they spend in hot delivery vehicles or warehouses. This will reduce the chances of your candles melting during transit.

Candle damage from hot cars
Candles are susceptible to damage from hot cars, with the potential for melting and spillage. The damage caused depends on the type of wax, the temperature, and the duration of exposure. Cars can reach temperatures of 71°C (160°F) on hot days, and wax melts at temperatures between 45°C and 145°F (depending on the type of wax). This means that candles are likely to melt in a hot car, especially those made from softer waxes like soy, coconut, or apricot wax, which have lower melting points.
The extent of the damage caused to a candle left in a hot car can vary. In some cases, the candle may only soften or lose its shape, while in others, it may completely melt and spill out of its container. If the candle is a pillar candle, it may melt through its packaging. Additionally, fragrance oils in candles can separate from the wax and pool on the surface, creating a fire hazard as the oil is flammable.
To reduce the risk of candle damage in a hot car, choose candles made from harder waxes like palm, paraffin, or beeswax, which have higher melting points. Alternatively, consider adding an additive to your wax to increase its melting temperature, such as palm steric acid or a universal additive. Another option is to blend two types of wax, such as combining 30% beeswax with 70% soy wax, to create a harder candle with a higher melting point.
If you need to transport candles in a hot car, there are a few precautions you can take. Wrapping candles in kitchen plastic wrap can help insulate them from the heat, and placing them in a cardboard box will provide an extra layer of protection. Cardboard egg cartons are especially useful for storing small votives or tealights and helping to keep them cool. Ultraviolet Light Absorbers (UVLAs) can also be added to candles as an additive to protect them from sun damage, although they may affect the colour, scent, and burn properties of the candle.
If your candle has already melted in a hot car, don't panic. You can still use it once it cools down and solidifies. Place the candle on a flat surface in a cool environment and ensure the wick is centred to reset. For container candles, be careful not to spill the wax as you move it, and avoid spilling wax everywhere.

Candle wax and car temperature
Candles are made from different types of wax, and each type has a unique melting point. For instance, coconut and soy wax candles usually melt at temperatures between 49°C and 54°C. Harder waxes like beeswax can withstand higher temperatures, whereas softer waxes like soy wax are more susceptible to melting in hot environments.
The temperature inside a car can quickly become extremely hot, especially during the summer months. On a hot day, the temperature inside a parked car can reach up to 71°C. This increase in temperature is influenced by several factors, including the colour of the car, the size of the car, and the materials used in its construction. As a result, candles left in a hot car may soften, lose their shape, or even melt entirely.
The length of time a candle is left in a hot car will also affect whether it melts. A candle can melt in a hot car within 25 minutes to 2 hours. If the candle is a pillar candle, it may melt in its packaging. If it is a container candle, it may be salvaged if it remains upright and can be placed on a flat surface to reset and harden.
To prevent candles from melting in a hot car, they can be wrapped in kitchen plastic wrap and placed in a cardboard box. Egg cartons are useful for storing small votives or tealights. Cardboard acts as an insulator, helping to keep candles cool and prevent melting. Ultraviolet Light Absorbers (UVLAs) can also be added to candles to protect them from the sun's rays, although these additives can affect the colour, scent, and burn properties of the candle.

Candle type and car interior temperature
The temperature inside a car can get extremely hot, especially during the summer months. On a hot day, the temperature inside a parked car can reach 71°C (160°F). Therefore, the type of candle and its wax is an important factor in determining whether it will melt in a hot car.
Soy wax candles, for example, typically melt at temperatures above 40°C. However, coconut and soy wax candles usually have melting points between 49°C (120°F) and 54°C (130°F). This means that these types of candles are more susceptible to melting in high temperatures and are likely to melt in a hot car. Harder waxes like beeswax, on the other hand, have higher melting points, with beeswax candles melting at around 145°F. Therefore, candles made from beeswax are less likely to melt in a hot car.
The size of the candle also matters, as smaller candles tend to melt faster than larger ones. Additionally, the style of the candle can impact the melting time. For example, a paraffin wax pillar candle may begin to melt within 25 to 30 minutes, whereas a container candle might remain upright and not spill over.
To prevent candles from melting in a hot car, it is recommended to wrap them in kitchen plastic wrap and place them in a cardboard box. Cardboard is a great insulator and will help keep the candles cool. Alternatively, you can add additives to the wax to increase its melting temperature. For example, palm stearic acid or a universal additive can be used to harden the wax.
