How this analysis is generated
Each ingredient on this product's published label is matched against our 237 source-cited chemical rules, each documenting a concern from peer-reviewed research and regulatory sources. Severity tiers:
- Avoid (red) — banned or restricted in the EU, UK or Canada but still legal in the US, IARC-listed, or strong contact-allergen evidence.
- Caution (amber) — regulatory caution, contamination risk, or condition-specific irritant.
- Mild (green) — low concern but commonly avoided in low-tox formulations.
Each flag links to its primary chemical-level source, and each condition pill links to a PubMed-indexed paper that discusses the chemical class in the context of that condition. Every citation is a real peer-reviewed paper — we don't link to Wikipedia or PubMed search pages. Some pairs use a topically-broad paper (e.g. a fragrance-allergen patch-test review) rather than a single-pair study where the literature is thin. The full evidence chain (chemical → mechanism → condition → paper) is one click away.
