Coverage & match quality
6 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 (3)
These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.
fragrance materialMENTHOL
- MENTHOL: The cooling component of mint oils, named by the EU as a fragrance substance to be declared on the label. EU Regulation (EC) 1223/2009, Annex III entry 338, inserted by Commission Regulation (EU) 2023/1545: 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. It is declarable in its OWN right, not by way of any component it carries. The name to look for on a label is "Menthol". The duty applies now. Transition footnote (40) lets stock that does not comply, lawfully placed on the Union market before the 31 July 2026 cut-off, be made available until 31 July 2028.
humectantSODIUM PCA, GLYCERIN
- SODIUM PCA: The salt of PCA, one of the water-holding substances the outer layer of skin makes for itself. Dörner C, Steinbinder J, Sachslehner AP, Sukseree S, Eckhart L, "Amino Acid Metabolism of the Skin: Control by Specific Enzymes and Contribution to Protective Functions", Metabolites 2025;15(9):601, DOI 10.3390/metabo15090601, open access, section "Glutamine Is Converted to Pyrrolidone Carboxylic Acid, a Component of the NMF": "pyrrolidone carboxylic acid (PCA), also known as pyroglutamic acid or 5-oxoproline, accumulates in the stratum corneum."
- 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".
soothingALLANTOIN
- ALLANTOIN: A skin protectant used at low levels in products aimed at irritated skin. FDA OTC skin protectant monograph, 21 CFR 347.10(a), lists allantoin as a skin-protectant active at 0,5 to 2%. Its labelled indications are 21 CFR 347.50(b)(1), "temporarily protects minor: cuts, scrapes, burns", and (b)(2), which covers chafed, chapped or cracked skin. The monograph does not give it the "minor skin irritation and itching" wording; that one belongs to colloidal oatmeal, sodium bicarbonate and one combination, and to topical starch without the itching half.
