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

    5 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.

    • 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.
    • common irritantSODIUM LAURYL SULFATE

      • 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/PARFUM

      • FRAGRANCE/PARFUM: 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.
    • humectantGLYCERIN

      • GLYCERIN: A humectant, and one of the two ingredients a comparison of moisturiser components found made a significant difference to skin hydration. FDA OTC skin protectant monograph, 21 CFR 347.10(h), lists glycerin as a skin protectant at 20 to 45%. On the humectant half: Jeong CB, Han JY, Cho JC, Suh KD, Nam GW, "Analysis of electrical property changes of skin by oil-in-water emulsion components", Int J Cosmet Sci 2013;35(4):402-410, DOI 10.1111/ics.12059, PMID 23621673, found that "glycerine and urea showed significant skin hydration effects compared with other humectants".
