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.

    • common irritantLANOLIN ALCOHOL, P-PHENYLENEDIAMINE, SODIUM LAURYL SULFATE

      • LANOLIN ALCOHOL: A rich wool-derived emollient that is also a long-standing patch-test allergen. American Contact Dermatitis Society, Allergen of the Year 2023: "Lanolin: The 2023 American Contact Dermatitis Society Allergen of the Year", Cutis 2023;112(2):78-81, DOI 10.12788/cutis.0825, PMID 37820332; FDA OTC skin protectant monograph, 21 CFR 347.10(k), lists lanolin as a skin protectant at 12,5 to 50%.
      • 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.
      • SODIUM LAURYL SULFATE: A strong cleansing agent used as the reference irritant in skin-irritation testing. OECD Test Guideline 439 (in vitro skin irritation, reconstructed human epidermis), paragraph 24: "The suggested PC is 5% aqueous SDS", sodium dodecyl sulphate, the same substance as sodium lauryl sulfate, CAS 151-21-3.
    • 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.
    • exfoliating acidSALICYLIC ACID, GLYCOLIC ACID

      • SALICYLIC ACID: A beta hydroxy acid that clears the inside of pores; the EU restricts its level and keeps it off children under three. SCCS Opinion on Salicylic Acid, Submission I (SCCS/1601/18, corrigendum of 20 to 21 June 2019); EU Regulation (EC) 1223/2009 Annex III entry 98, as amended by Commission Regulation (EU) 2021/850, which for purposes other than preservation caps it at 3,0% in rinse-off hair products, 2,0% in other products, and 0,5% in body lotion, eye shadow, mascara, eyeliner, lipstick and roll-on deodorant, and states "Not to be used in preparations for children under 3 years of age." Its separate PRESERVATIVE use sits at Annex V entry 3, capped at 0,5% (acid), where the salts carry the carve-out "except for shampoos".
      • GLYCOLIC ACID: An alpha hydroxy acid that loosens surface skin cells; it also makes skin more sun-sensitive while you use it. FDA, "Guidance for Industry: Labeling for Topically Applied Cosmetic Products Containing Alpha Hydroxy Acids as Ingredients" (announced at 70 FR 1721, 10 January 2005; FDA web pages title it "Labeling for Cosmetics Containing Alpha Hydroxy Acids"), which names this acid and recommends the statement "Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn."
    • rich occlusiveLANOLIN ALCOHOL

      • LANOLIN ALCOHOL: A rich wool-derived emollient that is also a long-standing patch-test allergen. American Contact Dermatitis Society, Allergen of the Year 2023: "Lanolin: The 2023 American Contact Dermatitis Society Allergen of the Year", Cutis 2023;112(2):78-81, DOI 10.12788/cutis.0825, PMID 37820332; FDA OTC skin protectant monograph, 21 CFR 347.10(k), lists lanolin as a skin protectant at 12,5 to 50%.
