What we flagged
amber
Ceteareth-20
Manufacturing process can leave 1,4-dioxane (probable carcinogen) and ethylene oxide as contaminants. Look for 'vacuum-stripped' products.
amber
Sodium Laureth Sulfate
Milder than SLS but still drying for sensitive skin.
amber
Resorcinol
Hair-dye coupler with thyroid-disrupting activity in animal studies.
amber
Sodium Sulfite
Documented MCAS, asthma and migraine trigger in sensitive individuals.
amber
Tetrasodium EDTA
Chelating agent — generally tolerated but documented MCAS trigger in case reports.
amber
M-Aminophenol
PPD-family hair-dye intermediate.
amber
Propylene Glycol
Common humectant. Documented contact allergen — especially for eczema-prone skin.

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.
