what makes a candle truly eco-friendly?
"eco-friendly" has become one of those phrases that appears on almost everything and explains almost nothing.
in the candle market especially, it gets used loosely. sometimes it means something. sometimes it's a font choice on a label that happens to be kraft paper. here's what it actually means when it's real — and what to check before you buy.
start with the wax
the wax is the biggest variable. most mass-market candles use paraffin wax, a petroleum by-product. it burns fine, holds fragrance well and is cheap to produce. it is not, by any reasonable definition, eco-friendly.
the alternatives:
soy wax is the most widely used natural wax in the UK. it's made from soybean oil, a renewable resource, and burns cleaner and more slowly than paraffin. it's biodegradable. the main caveat: soy farming has sustainability concerns at scale, so it's worth looking for brands that care about sourcing.
rapeseed wax is growing in popularity as a UK-grown alternative. shorter supply chains, lower food miles, still natural and renewable.
coconut wax burns very cleanly but is more expensive and often blended with other waxes.
blends are common and not inherently a problem — a soy/coconut blend can still be genuinely clean. the thing to watch for is "soy blend" being used to describe a candle that's mostly paraffin with a little soy added. always check what percentage is actually natural wax.
then check the fragrance
wax is one part of the equation. fragrance is the other.
synthetic fragrance oils can contain phthalates, which are chemical plasticisers linked to hormone disruption. they're not always labelled. "fragrance" on an ingredient list can legally cover hundreds of compounds.
what to look for: phthalate-free fragrance oils. paraben-free. some brands will specify this clearly. others won't mention it at all, which is a signal in itself.
a genuinely eco-friendly candle should be able to tell you exactly what's in the fragrance oil. if they can't or won't, that's worth knowing.
the wick matters too
most wicks are cotton, which is fine. some cheaper wicks use zinc or lead cores to keep them upright — these release trace metals when burned. look for cotton or wood wicks. good brands will tell you.
packaging
glass jars are recyclable and, if well-made, genuinely reusable. tin containers are recyclable. plastic anything in a candle context is harder to justify.
paper and cardboard outer packaging should be recycled or FSC-certified. the handwritten note is a nice touch that doesn't need to be wrapped in anything.
what "vegan" means in a candle
beeswax is the main non-vegan ingredient in candles. it's natural, it burns beautifully and some people prefer it. but it's not vegan.
soy wax, rapeseed wax and coconut wax are all vegan. as are most synthetic fragrance oils, though it's worth checking whether the brand tests on animals.
the blissli position
every blissli candle is made with 100% soy wax, phthalate-free and paraben-free fragrance oils, cotton wicks and a recyclable glass jar. vegan and cruelty-free. hand-poured in small batches in Surrey.
none of that is on the label as a marketing point. it's the minimum standard we were willing to work to when we started making these. because if you're burning something in your home every day, it should be something you'd actually choose to have there.
