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.

Cosmetics only · lead with safetyProduct data from public sources incl. Open Beauty Facts & EWG Skin Deep · their ratings never scraped or shown

    Coverage & match quality

    7 ratings · 2 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, 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%.
      • 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

      • 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".
    • 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%.
