Coverage & match quality
5 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 irritantMELALEUCA ALTERNIFOLIA LEAF OIL
- MELALEUCA ALTERNIFOLIA LEAF OIL: An essential oil whose oxidation products carry its sensitising potential; the EU assesses it as a moderate skin sensitiser. SCCS Scientific Opinion on Tea Tree Oil (CAS/EC 68647-73-4 / 285-377-1), SCCS/1681/25, adopted 30 October 2025, which concludes it is a moderate skin sensitiser. It does not set maximum levels of its own: it assesses the concentrations the applicant defended, and finds no concern at 2,0% in shampoo, 1,0% in shower gel, 1,0% in face wash and 0,1% in face cream, for oil conforming to ISO 4730:2017, in adults, in non-sprayable formats. It draws on the earlier SCCP opinions SCCP/1155/08 and SCCP/0843/04 and incorporates their data by reference; it says nothing about their status.
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.
barrier lipidLINOLEIC ACID
- LINOLEIC ACID: An essential fatty acid the skin barrier uses and cannot make for itself. Khnykin D, Miner JH, Jahnsen F, "Role of fatty acid transporters in epidermis", Dermatoendocrinol 2011;3(2):53-61, DOI 10.4161/derm.3.2.14816, open access: "The human body can produce all but two of the fatty acids it needs: linoleic acid (C18:2, n6) and alpha-linolenic acid (C18:3, n3)", and replacing linoleic acid with a non-essential fatty acid "will lead to barrier defects". Feingold and Elias, J Lipid Res 2024: linoleate "is required for the synthesis of a subgroup of acylceramides".
soothingZINC OXIDE
- ZINC OXIDE: A mineral UV filter that the FDA also recognises as a skin protectant. FDA OTC skin protectant monograph, 21 CFR 347.10(u), lists zinc oxide as a skin-protectant active at 1 to 25%. Its labelled indication is 21 CFR 347.50(b)(3), "dries the oozing and weeping of poison: ivy, oak, sumac". The monograph does not give it the "minor skin irritation and itching" wording.
