Every fact on this site, with its evidence grade, its caveats, and a link to the source.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
The industry / Review of other studies
The candle recipes tested in this study, the criteria for making them, and the study's funding all came from an advisory committee of candle and fragrance industry groups: the European Candle Association, National Candle Association, Latin American Candle Manufacturers Association, and the fragrance houses Arylessence, Belmay, Firmenich, Givaudan, International Flavors & Fragrances, Symrise, and Takasago.
Strong evidence.
Caveats
The authors' Declaration of Competing Interest states no known competing financial interests, alongside this acknowledged industry funding, study design input, and co-author industry affiliations (Arylessence, European Candle Association).
