Short answer: yes — but not all soy candles are created equal, and "soy wax" alone doesn't automatically mean safe. Here's everything you need to know before you buy.
What makes a candle toxic in the first place?
Most conventional candles are made from paraffin wax — a byproduct of petroleum refining. When burned, paraffin releases compounds including toluene and benzene, both classified as potential carcinogens. Studies have found that poorly ventilated rooms with burning paraffin candles can accumulate indoor air pollutants at levels that exceed outdoor air quality standards.
Beyond the wax itself, toxicity in candles can come from three other sources:
-
Synthetic fragrance oils — many contain phthalates, which are endocrine disruptors
-
Lead-core wicks — now banned in the US but still found in some imported candles
-
Synthetic dyes — some produce toxic byproducts when burned
The type of wax matters less than the overall formulation. A candle made with soy wax but loaded with synthetic fragrance and dyes is not inherently safer than a well-formulated paraffin candle.
Why soy wax candles are generally cleaner
Soy wax is derived from soybean oil — a renewable, plant-based resource. When burned, natural soy wax produces significantly less soot than paraffin and doesn't release the same petroleum-derived compounds. This matters especially for people with asthma, allergies, or chemical sensitivities.

What to look for in a truly non-toxic soy candle
When shopping for non-toxic candles, soy wax is a great starting point — but it's not the whole story. Here's the checklist we recommend:
1. 100% soy wax — not a blend
Many brands label their candles as "soy" even when the wax is a blend of soy and paraffin. Look for "100% soy wax" or "pure soy wax" explicitly stated on the product. Blends still carry some of the same risks as paraffin.
2. No synthetic dyes
Pure soy wax is naturally cream or off-white. If a candle is brightly colored, it almost certainly contains synthetic dyes. Unscented, undyed soy candles are the cleanest option — what you see is exactly what burns.
3. Clean wick — cotton or wood
Always check that the wick is made from natural cotton or wood. Avoid wicks with metal cores. Our MOORED Wooden Candle features three wooden wicks for an especially clean, crackling burn.
4. Fragrance transparency
If a candle is scented, the brand should be able to tell you exactly what's in the fragrance. "Fragrance oil" alone tells you nothing. Look for phthalate-free fragrance oils or natural essential oils. Our CRYSTAL Candles use carefully selected clean fragrance.
If a candle brand can't tell you exactly what's in the fragrance, that's a red flag. Transparency is the clearest sign of a truly non-toxic candle.
Are unscented soy candles the safest option?
Yes — unscented soy wax candles are the cleanest burning candles available. Without any fragrance or dye additives, you're burning pure plant-based wax with a natural wick. For households with babies, pets, or people with respiratory sensitivities, unscented is always the safest choice.
This is why the majority of our collection at Beyond Candle Store is unscented. Products like our PEONY Sculptural Candle, AXIS Sculptural Set, and HEART Wooden Candle are made from nothing but premium soy wax and a natural wick.
How long do soy wax candles burn?
Soy wax burns at a lower temperature than paraffin, which means it burns slower and longer. A well-made soy candle typically burns 30-50% longer than a paraffin candle of the same size. For sculptural soy candles, we recommend burning in 2-3 hour sessions to preserve the form and get maximum burn time.
Are eco-friendly candles better for the environment?
Significantly. Soy wax is:
-
Biodegradable — soy wax breaks down naturally, unlike petroleum-based paraffin
-
Renewable — soybeans are a sustainable crop, replanted seasonally
-
Lower carbon footprint — soy production has a smaller environmental impact than petroleum extraction
-
Easy cleanup — spilled soy wax cleans up with soap and warm water
At Beyond Candle Store, we pair our eco-friendly soy wax with sustainable packaging — because a clean-burning candle shouldn't come in wasteful packaging.
The bottom line
Soy wax candles are genuinely non-toxic and cleaner burning than paraffin — but only if the full formulation is clean. A truly safe non-toxic candle combines:
- 100% pure soy wax (no paraffin blends)
- Natural cotton or wood wick
- No synthetic dyes
- Transparent fragrance ingredients (or unscented)
Every candle we make at Beyond Candle Store — handcrafted in Chandler, Arizona — meets all four of these standards. That's our commitment to clean, sculptural, intentional craft.

Frequently asked questions
Are soy candles safe to burn around pets?
Unscented soy wax candles are generally considered safe around pets. Avoid scented candles around cats especially, as their livers cannot process many aromatic compounds. Always ensure good ventilation and never leave a burning candle unattended around animals.
Are soy candles safe during pregnancy?
Unscented, pure soy wax candles with natural wicks are the safest candle choice during pregnancy. Avoid strongly scented candles and ensure the room is well ventilated. When in doubt, consult your healthcare provider.
How can I tell if my candle is really soy wax?
Pure soy wax is naturally off-white or cream colored and has a slightly rough or frosted surface texture. It also burns cooler to the touch than paraffin. If a candle is pure white and perfectly smooth, it may contain paraffin. Always check the label for "100% soy wax."
Do soy candles smell as strong as paraffin candles?
Soy wax holds fragrance differently than paraffin — it tends to release scent more gradually and evenly rather than in a strong initial burst. Many people find soy candle scent throw more pleasant and less overpowering. Unscented soy candles have no scent by design.
