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.
Laws and loopholes / Government agency
The 2022 US cosmetics law does not cover air fresheners, cleaning products, or laundry products at all.
Strong evidence: MoCRA amends the FFDCA cosmetics chapter only; household products fall under CPSC/EPA law.

Laws and loopholes / Other evidence
FDA's food allergen labeling law explicitly does not apply to cosmetics, drugs, or household cleaning products, so fragrance allergens in those products have no allergen-naming duty under it.
Strong evidence: Says nothing about the separate MoCRA fragrance-allergen rulemaking, which is still pending.

Laws and loopholes / Other evidence
OSHA lists perfumes and colognes, cleaning products, pesticides and personal-care products among sources of workplace indoor air pollutants, but sets no limit or rule for any of them.
Strong evidence: Mentions are brief source lists; fragrance is not named as a category, and no health data are given.
