Soy Wax Candles
Soy candles are a plant-based wax alternative made by hydrogenating soybean oil. As consumer awareness of indoor air quality and product sourcing grows, soy wax has become a popular choice for wellness-conscious individuals attempting to avoid the use of synthetic, petroleum-based waxes like paraffin.
Renewable and Biodegradable
Soy wax is derived from soybeans—a renewable, biodegradable resource.
Cleaner Burning
A 2002 study found that, when compared to paraffin, soy wax combustion resulted in lower levels of volatile organic compounds (VOCs) and particulate matter, reducing potential indoor respiratory irritants.
Longer Burn Time
Soy wax has a lower melting point than many other waxes, allowing it to burn more slowly and evenly—offering a longer-lasting candle experience.
Aroma Retention
Known for its excellent scent throw, soy wax holds fragrance well—especially when paired with essential oils. This allows brands to deliver rich, natural aromas without relying on heavy, synthetic perfumes.
Health & Environmental Considerations
While soy wax is often seen as a cleaner option, any indoor candle combustion can release pollutants. A study by Salthammer et al. (2021) found that soy candles, though generally cleaner than paraffin, still emitted small amounts of formaldehyde, acetaldehyde, and VOCs—particularly when fragranced. To reduce exposure, burn candles in well-ventilated spaces and limit use to a few hours at a time. Read our full article on "Non Toxic Candles" for an analysis on the research.
Be mindful that many candles labeled "soy wax" are actually soy blends, often mixed with paraffin. For a truly cleaner burn, choose products labeled as 100% soy wax, and review ingredient lists when available.
Sustainability varies by brand, as large-scale soy farming can contribute to deforestation and monoculture. Look for brands that clearly outline ethical sourcing practices and/or participate in sustainable initiatives. Most brands have begun to include a "sustainability" section on their website where they lay out all of their efforts.
