Soy, paraffin, and coconut wax: what we do and do not compare

Wax is the loudest claim on a candle label. This guide does not compare these materials' performance, cost, prevalence, blend composition, cosmetic behavior, or health effects.

What this guide does not compare

This guide does not compare these materials' performance, cost, prevalence, blend composition, cosmetic behavior, or health effects. We have not collected attributable evidence for any of those comparisons.

That covers burn behaviour, scent throw, production cost, cosmetic appearance in the vessel, blend composition, and how blends are labelled. We hold no source for any of those topics, so we publish nothing on them.

Why we will not rank them anyway

A ranking is probably what you came here for. We are not going to give you one, because we would be inventing it. Any guide that ranks candle waxes confidently is either citing something we have not seen, or telling you more than it knows.

If a claim printed on a label is what is driving your decision, the maker is the party who has to support it. Ask them what it is based on.

What we publish instead

On Ember & Main, each burn figure identifies its publisher and we preserve documented disagreements. A figure appears only after someone opened the page it was published on and recorded the source and the date.

That is a narrower promise than a wax ranking, and it is one we can keep.

Questions

What people ask

Is soy wax healthier than paraffin?
We do not know, and we are not going to guess. This guide has not collected evidence sufficient to compare the health effects of different candle waxes, so we do not recommend one as healthier and we make no comparative claim about indoor air quality. If that is your concern, the appropriate sources are a medical professional or a public-health or environmental agency, not a candle comparison site.
Why does my soy candle look patchy?
We do not describe how any wax behaves in a vessel, because we have not collected attributable evidence for it. Use the care instructions supplied with the specific candle, and ask its maker whether what you are seeing is expected for their product.
