Coverage & match quality

9 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 (2)

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

common irritantPropylene glycol, p-Phenylenediamine
- Propylene glycol: A solvent that shows up in patch-test clinics, more often as irritation than as allergy. American Contact Dermatitis Society, Allergen of the Year 2018 (Jacob SE, Scheman A, McGowan MA, Dermatitis 2018;29(1):3-5).
- p-Phenylenediamine: A hair-dye coupler and one of the most frequently positive substances in patch-test clinics. EU Regulation (EC) 1223/2009, Annex III entry 8a permits p-phenylenediamine and its salts as a hair dye substance in oxidative hair dye products, at a maximum of 2% free base applied to hair after mixing; entry 8b separately permits them in products intended for colouring eyelashes, professional use only, at the same 2% limit, so this is not a hair-dye-only restriction. The general-use wording entry 8a mandates begins with the mixing ratio, then "Hair colourants can cause severe allergic reactions", "Read and follow instructions", "This product is not intended for use on persons under the age of 16", "Temporary “black henna” tattoos may increase your risk of allergy", a three-part "Do not colour your hair if" contraindication list, "Contains phenylenediamines" and "Do not use to dye eyelashes or eyebrows". The professional-use wording PREPENDS "For professional use only." and ends "Wear suitable gloves." where the general one ends with the eyelash sentence.
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".
