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

    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 (5)

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

    • commonly dryingISOPROPYL ALCOHOL

      • ISOPROPYL ALCOHOL: A fast-evaporating solvent with a drying finish, common in toners and hand products. International Chemical Safety Card ICSC 0554, Isopropyl alcohol, prepared by an international group of experts for the ILO and WHO: "Repeated or prolonged contact with skin may cause dryness and cracking." It describes a stronger exposure than a cosmetic formula.
    • fragrance materialHEXYL CINNAMAL, LINALOOL, BENZYL SALICYLATE, LIMONENE, BENZYL ALCOHOL, COUMARIN

      • HEXYL CINNAMAL: A jasmine-like fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 87: 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.
      • LINALOOL: A floral fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 84: 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.
      • BENZYL SALICYLATE: A faintly floral fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 75: 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. The entry was replaced by Commission Regulation (EU) 2026/909 of 27 April 2026, which caps it per product type from 0,004% in oral products to 4% in fragrance products; under its footnote (**), products not complying may not be placed on the Union market from 1 January 2027, nor made available from 1 July 2028.
      • LIMONENE: A citrus-smelling fragrance component named separately on the label; the one name covers three related isomers. EU Regulation (EC) 1223/2009, Annex III entry 88: 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 (37): stock that does not comply, lawfully placed on the Union market before the 31 July 2026 cut-off, may still be made available until 31 July 2028. It is marked on the racemic dl-limonene/Dipentene line and the (S)-(l-limonene) line, but NOT the (R)-p-mentha-1,8-diene (d-limonene) line, CAS 5989-27-5, whose duty was already running as entry 88 before Commission Regulation (EU) 2023/1545 and so needed no transition. All three isomers are declared under the single glossary name "Limonene", so that name on a label does not identify which of them is present.
      • 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.
      • COUMARIN: A sweet hay-scented fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 77: 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.
    • undeclared fragrance blendPARFUM / FRAGRANCE

      • PARFUM / 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 occlusiveDIMETHICONE

      • DIMETHICONE: A silicone that forms a film on the surface of the skin without an oily feel. FDA OTC skin protectant monograph, 21 CFR 347.10(g), lists dimethicone as a skin protectant at 1 to 30%.
