Coverage & match quality

6 ratings · 3 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 irritantCOCAMIDOPROPYL BETAINE, SODIUM LAURYL SULFATE
- COCAMIDOPROPYL BETAINE: A mild cleansing agent, but a recurring patch-test finding, usually traced to leftovers from how it is made. American Contact Dermatitis Society, Allergen of the Year 2004 (Fowler JF Jr, Dermatitis 2004;15(1):3-4).
- 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.
humectantPANTHENOL
- PANTHENOL: A provitamin B5 humectant used in products aimed at irritated and healing skin. On the humectant half: Ferreira VTP, Silva GC, Martin AA, Maia Campos PMBG, "Topical dexpanthenol effects on physiological parameters of the stratum corneum by Confocal Raman Microspectroscopy", Skin Res Technol 2023;29(9):e13317, DOI 10.1111/srt.13317, PMID 37753694, PMCID PMC10504581, open access, Introduction: "As a humectant, it has been shown to retain water more efficiently than other humectants during the last stages of dehydration..." On the soothing half, which that paper does NOT support: Cho YS, Kim HO, Woo SM, Lee DH, "Use of Dexpanthenol for Atopic Dermatitis—Benefits and Recommendations Based on Current Evidence", J Clin Med 2022;11(14):3943, DOI 10.3390/jcm11143943, PMID 35887707, open access, section 3.5: "To facilitate wound healing, dexpanthenol reduces inflammation, and promotes cell proliferation and epithelial remodeling."
