A Scientific Look at Candle Waxes & Fragrances: The Superior Choice for a Healthy Home
In an era of heightened awareness around environmental toxins and indoor air quality, the chemical composition of everyday household items is under greater scrutiny. This is particularly true for products that undergo combustion, like candles, as the materials chosen are the critical factors in determining the candle's emission profile.
At Mbur Candle Co., our exclusive use of 100% pure beeswax and cosmetic-grade fragrances is a decision rooted in material science and a commitment to public health. This is a scientific breakdown of common candle ingredients and why our choices lead to a safer, superior product.
A Comparative Analysis of Common Candle Waxes
The wax is a candle's fuel source. Its chemical origin dictates its combustion byproducts.
-
Paraffin Wax: The most common wax, paraffin is a hydrocarbon mixture derived from the de-waxing process of crude oil. As a fossil fuel byproduct, its thermal decomposition is known to release Volatile Organic Compounds (VOCs), including the known human carcinogen benzene (C₆H₆) and the neurotoxin toluene (C₇H₈), posing a clear health risk.
-
Soy Wax: A vegetable wax derived from hydrogenated soybean oil. From a health perspective, soy wax is considered non-toxic and does not release the carcinogenic compounds, benzene and toluene, that are associated with paraffin wax. While it is a renewable resource and burns cleaner than paraffin, it has performance drawbacks. Its low melting point can lead to a fast burn, and environmentally, its production is often linked to monoculture soybean farming, which contributes to deforestation and requires significant pesticide use.
-
Coconut Wax: Another vegetable wax derived from hydrogenated coconut oil. Like soy wax, coconut wax is non-toxic and is not considered carcinogenic. Its clean combustion profile means it does not emit the harmful toxins found in paraffin. It offers a very clean, slow burn and excellent fragrance diffusion. However, it is extremely soft and is almost always used as part of a blend with harder waxes for structural integrity. Like soy, its sourcing is tied to the environmental and ethical concerns of large-scale monoculture farming.
-
Beeswax: A complex natural ester, a long-chain polymer produced biologically by honey bees (Apis mellifera). Beeswax is the superior choice for several reasons:
-
Clean Combustion: Like the vegetable waxes, it is non-carcinogenic. Its chemical structure results in a burn that produces primarily water (H₂O) and carbon dioxide (CO₂) with negligible VOC emissions.
-
Air Purification: It is the only wax known to produce negative ions when burned. These ions bind with positively charged airborne particulates (dust, dander, pollen), neutralizing them and effectively removing them from the air.
-
Performance: With a high melting point (62-64°C), it burns longer and brighter than other waxes. It requires no chemical additives or blending for structural integrity.

The Complexity of Candle Fragrance: Essential Oils vs. Formulated Oils
A common misconception is that candles made with 100% essential oils are inherently safer or better. From a chemical standpoint, this is often not the case.
The Downsides of Using 100% Essential Oils in Candles:
-
Unintended Combustion Byproducts: Essential oils are highly volatile organic compounds. They are not chemically designed or tested for stability under the high heat of direct combustion. When a pure essential oil is burned, its complex structure can break down, or "crack," into different, potentially irritating or harmful compounds.
-
Poor Performance: Many essential oils have a low flash point, meaning they combust and burn off too quickly in a candle's hot melt pool. This results in a weak or rapidly fading scent, a phenomenon known as "scent burnout."
-
Safety & Sustainability: Many common essential oils are toxic to pets. Furthermore, producing a small amount of essential oil requires an immense quantity of plant matter, making their use in large-format products like candles highly unsustainable.
The Case for Scientifically Formulated Fragrance Oils:
At Mbur Candle Co., we use expertly crafted, phthalate-free fragrance oils. These are sophisticated blends of natural essential oils and safe, nature-identical aroma compounds that are specifically designed and safety-tested for optimal performance and stability in a candle.
This scientific approach ensures that the fragrance remains stable at high temperatures, providing a consistent, beautiful scent without the risk of chemical breakdown or the sustainability issues of pure essential oils. It is the safest and most effective way to fragrance a candle.
An Evidence-Based Conclusion
The decision to use 100% pure beeswax and cosmetic-grade formulated fragrances is based on empirical evidence. While vegetable waxes like soy and coconut offer a non-carcinogenic alternative to paraffin, beeswax stands alone with its combination of a clean burn, superior performance, and unique air-purifying properties.
