Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
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.
Green, natural and unscented / Government agency
Health Canada's current guidance (accessed 2026-09-27) states that a cosmetic labeled 'unscented' or 'fragrance-free' may contain a masking agent added to hide other odors, confirming a 2010 secondhand quote of the same policy word for word.
Strong evidence.
Caveats
Confirmed directly against Health Canada's current (2025-03-17/2026-04-24) guidance and its Cosmetic Regulations s.21.4(3) legal basis; no longer resting on a 2010 secondhand NGO quote alone. Does not measure how often masking actually occurs in Canadian products.
