Is Urbane Mess Defining Paste 85g low tox? Our scanner flagged 10 ingredients (2 in the avoid tier, 8 caution) on its published label, screened against our 237 source-cited chemical rules.
Slowly releases formaldehyde. Common eczema and contact dermatitis trigger.
Chemical UV filter. Documented endocrine disruptor; restricted in Hawaii, Florida, Aruba.
FDA Matta et al. JAMA 2019 (systemic absorption); Hawaii Act 104 sunscreen restriction
Wool-derived emollient. Comedogenic and a documented contact allergen.
Manufacturing process can leave 1,4-dioxane (probable carcinogen) and ethylene oxide as contaminants. Look for 'vacuum-stripped' products.
Synthetic polymer film-former. Microplastic concern (rinse-off products), low-grade monomer-residue concern.
Gut inflammation concerns; contested in research literature but worth a trial of avoidance for IBS.
Chelating agent — generally tolerated but documented MCAS trigger in case reports.
Can react with nitrosating preservatives to form nitrosamines (carcinogenic).
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:
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.
This is automated analysis of a published label, not medical advice — always verify the label yourself before changing products. Methodology and source list at scan.lowtoxgear.com.
