The one rule

We never blend a score that hides who disagrees. Funding model travels with every rating. Weights are computed at read time and never stored.

    Coverage & match quality

    6 ratings · 1 of 4 axes

    • Some ratings rest on an automatic match that has not been human-reviewed.
    • Fewer raters reach smaller-brand products, so a missing rating is not a clean bill of health, only a gap.

    What these ingredient tags mean (4)

    These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.

    • commonly dryingALCOHOL DENAT

      • ALCOHOL DENAT: Denatured ethanol: a fast-evaporating solvent that thins a formula and leaves a dry finish. International Chemical Safety Card ICSC 0044, Ethanol (anhydrous), prepared by an international group of experts for the ILO and WHO: "The substance defats the skin, which may cause dryness or cracking." WHO Guidelines on Hand Hygiene in Health Care (2009) records depletion of the skin lipid barrier by lipid-dissolving alcohols, and also that "the lipid-dissolving effect of alcohols is inversely related to their concentration". Both describe stronger exposures than a cosmetic formula.

    • common irritantP-PHENYLENEDIAMINE

      • P-PHENYLENEDIAMINE: A hair-dye coupler and one of the most frequently positive substances in patch-test clinics. EU Regulation (EC) 1223/2009, Annex III entry 8a permits p-phenylenediamine and its salts as a hair dye substance in oxidative hair dye products, at a maximum of 2% free base applied to hair after mixing; entry 8b separately permits them in products intended for colouring eyelashes, professional use only, at the same 2% limit, so this is not a hair-dye-only restriction. The general-use wording entry 8a mandates begins with the mixing ratio, then "Hair colourants can cause severe allergic reactions", "Read and follow instructions", "This product is not intended for use on persons under the age of 16", "Temporary “black henna” tattoos may increase your risk of allergy", a three-part "Do not colour your hair if" contraindication list, "Contains phenylenediamines" and "Do not use to dye eyelashes or eyebrows". The professional-use wording PREPENDS "For professional use only." and ends "Wear suitable gloves." where the general one ends with the eyelash sentence.

    • fragrance materialBENZYL ALCOHOL

      • BENZYL ALCOHOL: Used both as a fragrance component and as a preservative; the EU names it either way. EU Regulation (EC) 1223/2009, Annex III entry 45: a fragrance substance whose presence must be indicated in the list of ingredients above 0,001% in leave-on and 0,01% in rinse-off products, because of established contact-allergy risk. That entry carries transition footnote (38), which is footnote (37) plus a condition: stock that does not comply may still be made available until 31 July 2028 only "provided that they comply with the restrictions applicable on 15 August 2023", and only if it was lawfully placed on the Union market before the 31 July 2026 cut-off. Entry 45 covers its non-preservative use; it is separately an allowed preservative at Annex V entry 34.

    • undeclared fragrance blendFRAGRANCE

      • FRAGRANCE: A blend the label does not itemize, so what is in it cannot be read from the ingredient list. EU Regulation (EC) 1223/2009 permits the collective term "parfum"; the SCCS Opinion on Fragrance Allergens (SCCS/1459/11) reviews the contact-allergy evidence for the substances it can contain.
