Candles have been used as a source of light for thousands of years, dating back to ancient Egypt. While they are aesthetically pleasing, they can also be a hassle when they start dripping. The messiness of traditional candles has led to the creation of dripless candles, which are made from wax with a higher melting point. These candles are designed to burn slowly and cleanly, without creating a mess. While stearin candles, which are made from plant-based or animal-based stearin wax, are often marketed as dripless, they may still produce drips, especially if they have varying diameters. To create dripless candles at home, one can add stearic acid to the wax, increasing its melting point and making it harder.

| What are stearin candles? | Candles made with wax that contains stearic acid, which is formed when animal fats are broken down by the action of an alkali, such as sodium hydroxide. |
| Why do they not drip? | The stearic acid makes the wax harder, increasing its melting point so that the heat of the candle is not enough to melt the edges. |
| Are there any downsides? | Even dripless candles can sometimes drip, for example, if the candle is tilted or if there is a draft. |
| Are there any natural alternatives to stearin candles? | Beeswax is the only naturally dripless material used to make candles and is a healthier alternative to paraffin wax. |
| Are there any plant-based alternatives to stearin candles? | Yes, some manufacturers have made candles from plant-based wax, but these are much trickier to make since their wax is naturally softer than paraffin wax. |

What You'll Learn
Stearin candles are made from palm oil or animal fats
Stearin, also known as stearic acid, is a valuable additive in candle-making. It is a natural wax derived from animal or vegetable sources, such as tallow or palm oil. Historically, stearin was produced from animal fats, but today, it is mainly derived from palm or coconut oil.
Stearin provides many benefits when used in candles. Firstly, it increases the melting point of the wax, making the candles harder and less prone to dripping. This is especially advantageous in warmer climates, as stearin candles are less likely to melt, sag, or lose their shape. Secondly, stearin makes the wax more opaque, resulting in intensely coloured candles. Additionally, stearin candles produce a brighter, longer-lasting flame and burn more slowly, providing a longer-lasting candle with reduced mess and less frequent replacements.
The use of stearin also offers sustainability benefits. Stearin is a renewable and ethical source that can be sourced from RSPO-certified palm oil. It produces the lowest CO2 emissions of all wax types, with a 60% reduction in CO2 emissions compared to paraffin or soy wax candles and a 20% reduction compared to palm wax candles. Furthermore, stearin is biodegradable, ensuring it breaks down naturally without causing harm to the environment.
In terms of quality, stearin candles are considered superior, noticeable in their increased weight. They possess a natural, mild scent that adds a pleasant fragrance without the need for synthetic fragrances. Stearin is easy to work with and can be blended with other waxes or poured into moulds to create custom candles. Overall, stearin candles offer a high-quality, eco-friendly, and functional option for candle enthusiasts.

They are harder and smoother than other candles
Stearin candles are made from stearic acid, a substance formed when animal fats are broken down by an alkali such as sodium hydroxide. The discovery of stearic acid in the 19th century revolutionized the candle-making process, as it burned well and was inexpensive to produce. However, one drawback was that stearic acid was brittle. Candle-makers solved this problem by adding paraffin, a petroleum byproduct. Unfortunately, this made the wax melt more easily, resulting in dripping.
To create dripless candles, manufacturers increase the amount of stearic acid in the wax, making it harder and raising its melting point. This higher melting point ensures that the heat of the candle flame is insufficient to melt the edges, thus preventing dripping. The addition of stearic acid also makes the wax smoother, resulting in a shiny and scratch-resistant finish.
The Maison Balzac Volute Candles, for example, are made from plant-based stearin wax derived from palm oil. These candles have a hard and smooth texture, free of pockmarks or casting flaws, and are resistant to scratches. While the Volute candle did exhibit some dripping during testing, the drips were easier to dislodge and remove from surfaces compared to other waxes.
In addition to stearin candles, beeswax is another naturally dripless option. Beeswax candles burn cleanly and are a healthier alternative to paraffin wax, making them ideal for individuals with allergies. They produce a mildly sweet smell and are free of the stickiness sometimes associated with paraffin and beeswax candles. However, beeswax candles have a shorter burn time than their paraffin counterparts.
Overall, stearin candles offer a harder and smoother alternative to traditional wax candles, providing a longer-lasting, cleaner burn with minimal dripping. Their unique properties make them a desirable option for those seeking a mess-free and aesthetically pleasing candle experience.

They are dripless, but can still drip in certain conditions
Stearin candles are made from stearic acid, a substance derived from the breakdown of animal fats with an alkali, such as sodium hydroxide. This process forms sodium stearate, which then becomes stearic acid when treated with an acid. Stearic acid burns well and is a cheap, effective ingredient for candle-making.
However, it has its drawbacks. One issue is that stearic acid is brittle, which can be solved by adding paraffin to the mix. But this causes another problem: the candle wax melts more easily, causing it to drip down the sides and create "waxicles".
To make stearin candles dripless, manufacturers increase the amount of stearic acid in the wax. This raises the melting point of the wax, preventing it from dripping. However, even dripless candles can still drip under certain conditions. For example, tilting the candle can cause the liquid wax to run out. A strong draft can also blow hot air or the flame to one side, causing the hard rim to melt and drip.
While stearin candles can provide a clean-burning flame with little to no drips, they are not entirely dripless in all conditions. The thickness of the candle also plays a role in dripless candles, as thicker candles are less likely to melt at the edges. Additionally, a thicker wick can help reduce dripping by absorbing more wax, which is then burnt off.

They are more expensive than regular candles
Stearin candles, also known as dripless candles, are more expensive than regular candles. This is because they are harder to make, requiring the addition of stearic acid to the wax to increase its melting point and prevent dripping. The higher melting point also means that stearin candles burn more slowly and last longer than regular candles, which may offset the higher cost to some extent.
Stearin candles are made by adding stearic acid to wax, which makes the wax harder and raises its melting point. This process was discovered in the 19th century with the advent of the chemical industry and has been used to make dripless candles ever since. The stearic acid is derived from animal fats or plant-based sources, such as palm oil.
The addition of stearic acid increases the cost of the candle, as it requires more materials and labour to produce. However, the resulting candle is more user-friendly and creates less mess, making it a popular choice for those who burn candles frequently.
While stearin candles are generally more expensive than regular candles, the price can vary depending on the brand, size, and quality of the candle. Some stearin candles may be more affordable than others, but they will still typically cost more than a regular candle of comparable size and quality.
It is worth noting that even dripless candles can sometimes drip, especially if they are tilted or subjected to a strong draft. However, they are designed to minimise dripping and will generally produce less mess than regular candles. For those who are willing to pay a premium for the convenience and longer burn time of a dripless candle, stearin candles can be a worthwhile investment.

They are longer-lasting than regular candles
Stearin candles are longer-lasting than regular candles. The addition of stearic acid to paraffin wax increases the melting point of the candle, making it harder and raising its melting point. This means that stearin candles take longer to melt and are less likely to drip, even when tilted. The higher melting point also means that the wax is absorbed and burned off through the wick, resulting in a longer-lasting candle.
Stearin candles are available in two main designs: thick pillar candles and slender taper candles. The thickness of the candle also contributes to its longevity, as a thicker candle will take longer for the flame to melt the edges. Additionally, stearin candles often have thicker wicks, which absorb more wax. This reduces the build-up of liquid wax and allows the candle to burn for a longer period without dripping.
The longevity of stearin candles is further enhanced by the fact that they are dripless. Regular candles can create large messes due to dripping wax, which not only causes inconvenience but also reduces the overall burn time. Stearin candles, on the other hand, burn cleanly and efficiently, making the most of the wax without creating a mess. This ensures that the candle lasts longer and provides a more cost-effective option for consumers.
While stearin candles may cost more upfront, their longer-lasting nature means they offer better value for money in the long run. By burning efficiently and minimising wax wastage, stearin candles provide a more sustainable and economical choice for those who frequently burn candles. The reduced mess and longer burn time make stearin candles a preferred option for those seeking a convenient and enduring lighting solution.
