Is Schwarzkopf Live Colour Hair Dye Silver Toner Semi Permanent each low tox? Our scanner flagged 4 ingredients (4 in the caution tier) on its published label, screened against our 237 source-cited chemical rules.
Weakly oestrogenic preservatives. Endocrine concerns particularly relevant for hormonal conditions.
Milder than SLS but still drying for sensitive skin.
Manufacturing process can leave 1,4-dioxane (probable carcinogen) and ethylene oxide as contaminants. Look for 'vacuum-stripped' products.
Ethoxylated surfactants — 1,4-dioxane contamination concern plus mild stripping action.
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.
